Enantioselective Catalytic Boronate Reactions
The development of new chemical methodologies is an important objective of organic synthesis. An area that continues to inspire chemists is the chemistry of organoboranes and boronates. The unique properties of boron and the ability to activate organic boronates to deliver carbon nucleophiles has yielded an impressive array of chemical methods and processes. We will extend the ability of organoboranes and boronates to deliver carbanion equivalents in novel condensation reactions including chemoselective carbonyl condensations and multicomponent reactions. The reactions will be rendered asymmetric through the development of asymmetric catalysts and chiral boronate reagents and the utility of the methods developed demonstrated by the asymmetric synthesis of pharmaceuticals and natural products. Significant advances have been made in the mechanistic understanding of boronate activation via ligand exchange with chiral diols. We will use the mechanistic insight we have obtained to expand the repertoire of reactions catalyzed by dynamic ligand exchange processes to include acyl cyanides as electrophiles, borono-Petasis reactions, and ortho-quinone methide chemistry. Our continued interest in reaction discovery has led to the identification of chiral diol acid catalysts capable of promoting the enantioselective addition reactions to acetals. We seek to explore this reactivity and expand it to include types of functionalized nucleophiles in additions to oxoniums and iminiums and boronate hetero-Diels–Alder reactions. Goals of the research program include developing a breadth of reactivity, providing access to novel chiral blocks, and new reaction development. Bond constructions are selected to access chiral synthetic intermediates that could be used in the construction of pharmaceuticals and natural products. The results will transform the way boronate nucleophiles are utilized in enantioselective synthesis.

Probing the role of membrane and cholesterol on APP-C99 structure and dynamics
Aggregation of proteins of known sequence is linked to a variety of neurodegenerative disorders. Familial mutations in the Amyloid Precursor Protein (APP), from which the amyloid β (Aβ) protein associated with Alzheimer’s Disease (AD) is derived, have been linked with the early onset of amyloid disease.
With this computational and theoretical research grant, augmented by synergistic experimental research collaborations, we will determine the structure and dynamics of the 99 amino acid transmembrane fragment of APP (APP-C99) in membrane environments in order to address fundamental biophysical questions articulated in three Specific Aims. (1) We will explore how length, sequence, and membrane composition influence the structure of the APP-C99 monomer. (2) The structures of APP-C99 dimers and the associated stability as well as the monomer-dimer equilibrium are also influenced by membrane composition and C99 sequence. We will investigate the influence of these environmental factors on the structure and dynamics of dimer formation. (3) We will also determine how APP-C99 interacts with cholesterol and cholesterol-analogs, as well as how those interactions influence APP-C99 structure and dimerization.
Plasmonically Enhanced Stimulated Coherent Spectroscopy
There is growing interest in using plasmonics to enhance and control chemistry on surfaces for applications such as chemical catalysis, pollution mitigation and energy conversion. The proposed time-domain experiments are aimed at developing a better dynamical and structural description of how molecules interact with plasmonic materials. Differences in energy fluctuation timescales, interaction strengths and energy distributions are anticipated for molecules on plasmonic surfaces as compared to molecules in liquid solutions. Characterizations of these properties are central to understanding chemical activity occurring on these substrates. Plasmonically enhanced stimulated coherent vibrational and electronic spectroscopic measurements of analytes on plasmonic substrates will be obtained to learn about these interactions. Fabricated metal nanoparticle cluster arrays will be employed here. This substrate type provides a wide range of design parameters that will be used to maximize signal strengths and robustness for the planned studies. The proposed research effort will be carried out by two Boston University PIs with complementary expertise in ultrafast spectroscopy and nanoscience.

Chemical probing of RNA tertiary structure in a whole transcriptome at single‐atom resolution
RNA (ribonucleic acid) is now widely appreciated to be a key participant in nearly all of the activities of the cell, yet we have limited information on the three-dimensional structures of most RNA molecules. This presents a challenge, because we know that the biological function of an RNA molecule depends on its structure. To understand the relationship between structure and function for the large number of RNA molecules that populate the cell, new high-throughput experimental approaches for structure determination are needed. The aim of this project is to develop a new experimental method that can provide detailed information on the three-dimensional folding of all the RNA molecules in a cell, in one experiment. The new method combines chemical probing of RNA structure by the hydroxyl radical, the quintessential Reactive Oxygen Species, with analysis by high-throughput sequencing, so that the structures of all RNA molecules in a cell can be monitored simultaneously.

Chemical Synthesis of Complex Natural Products for Translational Science
The National Institutes of Health, Institute of General Medical Sciences (NIGMS), has awarded Professor John Porco and coworkers (http://sites.bu.edu/porcogrp/) a five year MIRA (R35) grant entitled “Chemical Synthesis of Complex Natural Products for Translational Science.” The Maximizing Investigators’ Research Award (MIRA-R35), an Outstanding Investigator Award, is a grant that provides support for all of the research in an investigator’s laboratory that falls within the mission of NIGMS. Within these bounds, investigators have the freedom to explore new avenues of inquiry that arise during the course of their research. The goals of the MIRA (R35) research program are to continue chemical syntheses of bioactive molecules and expand efforts and capabilities in translational science. The MIRA effort effectively replaces two previous NIGMS-funded RO1 grants (Biomimetic Synthesis of Complex Natural Products (GM-073855) and Chemical Synthesis of Bioactive Flavonoid and Xanthone-Derived Natural Products (GM-099920) which were highly productive and led to 41 publications from 2010 – 2015. As part of the MIRA project, the Porco group will continue development of novel synthetic methodologies for concise entry to bioactive classes of natural products including oxaphenalenones, meroterpenoids, polyprenylated acylphloroglucinols, tetrahydroxanthones, and dimeric chromones. The project will also continue major emphasis on collaborations to study biological properties and mode of action (MoA) of target molecules for ultimate use as pharmacological therapies for human cancers as well as viral and bacterial illnesses.

SusChEM: Glycerol Polycarbonates as New Biomaterials
The future development of medical devices. Scientific advances, such as those described in this NSF sponsored research, will support US industries, which play an important role in this medical polymers market estimated to exceed $3.5 billion by 2018. This grant support undergraduate students and graduate students, who will benefit from an interdisciplinary cutting-edge research and educational experience that encompasses training in biomaterials and polymer chemistry. Students will be encouraged to think independently and creatively while recognizing the importance of collaborating with other experts (e.g., materials scientists, pathologist, biomedical engineers, and patent lawyers). These activities will contribute to positive societal outcomes by fostering excitement for basic research while educating and training a future workforce.
In the biomaterials and biomedical field, degradable polymers such as poly(lactic acid) and poly(glycolic acid) are widely studied and are an integral component of many medical device products. Although extensively used, these poly(hydroxy acid)s possess a number of limitations including: 1) limited capability for backbone functionalization; 2) acidic products upon degradation; and 3) poor control over molecular weight and dispersity. Consequently, there is significant need for new polymeric biomaterials that are amenable to facile modification, multiple processing or manufacturing methods, and controlled degradation without the generation of a local acidic environment. With NSF funding, the PI (Grinstaff) and his team will design, synthesize, and evaluate of a novel class of natural metabolite-based, non-toxic, and biodegradable polymeric materials based on a polycarbonate of glycerol. The activities in this highly interdisciplinary and cutting-edge research environment will also afford educated and trained undergraduate and graduate students for employment in industry and academia.

Illuminating Dynamic Receptor Clustering in the Epidermal Growth Factor Receptor
Dysregulation of members of the epidermal growth factor (EGF) receptor (EGFR) family is associated with oncogenesis and tumor growth. Due to its relevance in cancer development, EGFR is an important target in cancer drug discovery, and several EGFR targeted therapies have already been developed. Their clinical success has, however, often been modest, reinforcing the need for a more complete understanding of the EGFR signaling pathway. This proposal focuses on the insufficiently understood role of large-scale EGFR associates (“clusters”) in signaling initiation and transduction, in particular. While it has long been known that ligand induced dimerization plays a critical role in receptor signaling, there is growing evidence that this textbook model needs to be augmented to account for the heterogenous lateral distribution of the receptor in the plasma membrane. The local enrichment of the receptors in ”micro-domains” or ”nanoclusters” could strongly affect cooperative receptor interactions and shift the local EGFR association equilibria through a local concentration effect. The experimental investigation of the fundamental mechanisms underlying the large-scale receptor organization with conventional fluorescence microscopy remains challenging, due to the method’s limitation with regard to throughput, spatial and temporal resolution, and maximum observation time. Plasmon Coupling Microscopy (PCM) is a novel non-fluorescence based approach that uses electromagnetic interactions between noble metal nanoparticles (NPs) to investigate receptor clustering on subdiffraction limit distances (but beyond the spatial barrier o Fluorescence Resonance Energy Transfer, FRET). NP’s do not blink or bleach, are very bright, and can be imaged in a conventional widefield microscope. Consequently, PCM facilitates the monitoring of EGFR clustering without limitations in observation time in many individual cells simultaneously. This competitive renewal builds upon the plasmon coupling based tools developed in the previous funding cycle and outlines a vigorous research plan to elucidate the structural origin of dynamic EGFR clustering. PCM will then be applied to test the hypothesis that receptor clustering regulates the mode and strength of signaling and to elucidate the mechanisms underlying a spatial regulation of signaling intensity and outcome. The obtained insight will improve the understanding of spatial regulation mechanisms for a broad range of receptors. Noble metal NPs are not only superb optical labels for characterizing EGFR clustering in the plasma membrane, but they also represent potential therapeutic tools to restore and enhance negative EGFR signaling after covalent attachment to EGF. This hypothesis is experimentally tested in this proposal. If successful, this strategy would provide a new approach for overcoming apoptosis evasion in cancer.
Research For Undergraduates Program: Chemistry Research Addressing Biological Problems
This REU site will afford 30 undergraduates (10 per summer) the opportunity to engage in cutting edge, basic chemical research projects that address biological problems. REU students can choose from among 24 groups in BU’s Departments of Chemistry, Biology, or Biomedical Engineering. They will work in newly renovated laboratories, have access to the synthetic and computational resources of BU’s leading research centers, and be trained on state-of-the art instrumentation. The goal of the program is to provide undergraduates from 4-year colleges and community colleges who have limited or no research opportunities at their home institutions with an intensive, interdisciplinary research experience. At least 50% of the participants will be from community colleges with no research opportunities at their home campuses. The demographic aim is to have at least 70% of the students to be underrepresented minorities and at least 50% to be women. The program will also give preference to veterans applying from the target institutions. By fully integrating the REU students into the daily life of the laboratories and through mentoring by faculty, graduate students, and postdoctoral research associates, the REU students will fully experience the breadth of chemistry research and be motivated to pursue careers in science.

Chemical Transformations Enabled by Flow Chemistry
This award funds specific projects that are integral to the long term development of the Beeler Research Group. The overarching objective of our research is synthesis of small molecules that are used as tools to study human diseases. To achieve these goals we have identified a number of reactions that are highly enabled by flow chemistry. The scientific projects outlined in this proposal will result in sigfnificant advances toward the synthesis of a number of important biologically active molecules. Furthermore, the projects will provide advancements in flow chemistry that will enable chemists in acadmia and industry to implement a number of challenging reactions. The education projects in the proposal will provide training for undergraduates in flow chemistry, which is emerging as a critical technology in industry. The outreach projects will provide high school students from a wide range of socioeconomic backgrounds with a foundational path toward STEM higher education and careers. The first Aim is focused on expanding the utility of our flow photochemistry platform to develop reactions that will be highly useful in synthesis and medicinal chemistry. The second Aim is to develop a platform that is capable of milligram to multigram scale electrochemical reactions in flow. The third Aim will utilize highly reactive diazoalkanes in a Buchner reaction to access complex scaffolds. The proposal also outlines our continued involvement in outreach and education, including the Upward Bound program at Boston University to educate local high school students in chemistry, developing a summer camp for high school students, and integrating flow chemistry into the undergraduate laboratory curriculum.

Elucidating the role of ATP in cytosolic iron sulfur cluster biogenesis
Dr. Perlstein’s research focuses on how metals are mobilized and monitored within the cell so that they get to where they need to go and do not end up in places they shouldn’t. With this new five-year grant, Dr. Perlstein plans to unravel the molecular mechanism by which iron-sulfur cluster cofactors are assembled in the cytosol of eukaryotic organisms. Since inhibition of this first step in cluster biosynthesis can lead to defects in DNA replication, DNA repair and protein synthesis, she expects this work will provide new insight into how cluster biogenesis affects these other fundamental biochemical pathways.
With the CAREER award, Perlstein also plans to develop new undergraduate course curriculum as well as building on current STEM outreach program efforts to begin training the next generation of scientists.

Efficacy and Safety of a Novel, Implantable Drug-Eluting Film in Sarcoma
Despite aggressive multimodality therapies combining surgery, radiation, and/or chemotherapy, mesothelioma is essentially a universally fatal cancer with the majority of patients succumbing to local recurrence. To date, there is no effective cure for this disease or means to prevent recurrence. Consequently, new approaches, biomaterials, and mechanisms to deliver pharmacologically active agents are needed. In the current proposal, we utilize a murine model of human mesothelioma to investigate a new approach to reduce intracavitary tumor recurrence with the delivery of chemotherapy via unique tumor localizing polymeric nanoparticles (NPs) administrated locally at the time of surgical resection. The particle localizes to tumor in situ where upon endocytosis these “expansile” nanoparticles (eNPs) undergo a pH dependent transformation and swell from 100 nm to 1000 nm in diameter thus releasing the encapsulated chemotherapeutic agent intracellularly and acting as a drug depot, or reservoir, to deliver high local drug concentrations. Uniquely, expansion of eNPs also results in a functional depot whereby subsequently delivered intracavitary chemotherapy is concentrated inside eNP with prolonged delivery in situ at the sites of tumor where eNP accumulate. This is in contrast to conventional polymer delivery systems that degrade (e.g., poly(lactic-co-glycolic acid) particles), and result in burst release of their drug payload. We hypothesize that these eNPs will, via this unique mechanism, afford a higher intracellular concentration of paclitaxel (Pax), with greater efficacy in the prevention of local recurrence of mesothelioma after surgery that is superior to standard resection or Pax alone without adversely affecting healing at the surgical site. Importantly, we have data demonstrating that eNPs are readily internalized by cancer cells, act as a drug depot, and are superior to the standard Pax-Cremaphor formulation in preventing microscopic malignant disease in vivo.

Dissolvable Hydrogel Dressing for the Treatment of Burns
This will study the synthesis, characterization, and evaluation of a hydrogel dressing that dissolves and can be easily removed from the wound surface of a patient with second degree burns with no further trauma. Burns are one of the most common and devastating forms of trauma. Each year, more than 300,000 people die from fire-related burn injuries and millions suffer from burn-related disabilities and disfigurements with psychological, social, and economic effects on both the survivors and their families. Dressing removal is reported to be the time of most pain (after the burn itself) and opioids continue to be the mainstay of treatment for the burn patient. The duration of a burn dressing change in a typical injury requiring ICU/OR level care is often at least 60 minutes with induction of general anesthesia, which can extend to more than three hours depending on the case. At present, all clinically approved available dressings adhere to the wound surface so that each change of dressing leads to traumatization of newly formed tissues on the outer layer of the body’s surface, delayed healing, and great personal suffering for the injured patient. The proposal describes a thiol terminated dendron and a bifunctional NHS-activated PEG that react with each other to form a thiolester linked hydrogel dressing that can be subsequently dissolved by exposure of an aqueous thiol solution via a thiol-thiolester exchange mechanism. These experiments will test the hypothesis that a hydrogel-based, dissolvable burn dressing will provide a barrier to infection, promote wound healing, and be easily removable on demand. Importantly, it presents preliminary data demonstrating the synthesis, characterization, and performance of a dissolvable hydrogel dressing prototype.
Tuning directionality for CO2 reduction in the oxo-acid:ferredoxin superfamily
Exploiting catalytic chemistry for bioenergy production requires a detailed understanding of the molecular mechanisms of multi-electron redox processes, particularly those that transform/capture CO2. Understanding the molecular details of these complex reactions is a major challenge in modern energy science, particularly in the context of CO2 transformations, and the way in which bacteria and archaea capture CO2 for biomass. Here, we have focused on the remarkable catalysts used by nature to achieve either the oxidative liberation of CO2, or its formal reduction (and capture) in the form of useful intermediaries en route to biomass.
The enzymes that achieve CO2 reductions are highly powerful catalysts; yet very little is known about how they work, nor how they can be tuned to favor CO2 reduction chemistry. Through the completion of the project, this knowledge gap will be addressed in the context of the enzymatic chemistry of the oxo-acid:ferredoxin oxidoreductase (OFOR) superfamily, which is capable of CO2 reduction. We believe that our studies of the OFOR superfamily will reveal the molecular details of how nature biases the reactivity of an enzyme to preferentially reduce CO2. These efforts will yield foundational knowledge that will be broadly applicable to marrying the thermodynamics of redox reactions to atomistic information of enzymatic mechanism. We will examine a series of OFOR enzymes through three Aims over a 3-year period.
BU Chemistry is pleased to announce a 3-year renewal of funding for our NSF Research Experiences for Undergraduates (REU) Program. This summer program, hosted by the Chemistry Department, provides students from primarily undergraduate institutions with opportunities to work in advanced research laboratories. Of the 33 students who participated in the program over the past three years, 75% came from underrepresented minority groups, better than 60% were women, and more than 50% came from community colleges. Many of them co-authored peer-reviewed publications, presented their findings at conferences, and/or decided to attend graduate school, including BU. Another measure of the program’s success is its ever-expanding pool of applicants, with over 1,000 applications received for the summer 2015 program alone.
Chemistry would like to give special recognition to the efforts of Professors John Snyder, Principal Investigator (PI), and Linda Doerrer, co-PI, whose hard work and commitment to the program made this renewal possible.
The Chemistry Department is accepting applications now for the Summer 2016 session. For more information, visit the BU Chemistry REU.
The National Science Foundation’s Research Experience for Undergraduates Program supports active research participation by undergraduate students in any of the areas of research funded by the National Science Foundation. For the second time, BU Chemistry has received one of these coveted site awards. Focused on the theme “Fundamental Research in Chemistry Addressing Problems in Biology,” the 3-year program (2012-2015) is led by Professors John Snyder (Principal Investigator) and Linda Doerrer (Co-PI).
Professor Linda Doerrer and her research group have received a 4-year, $710,000 grant from the Office of Basic Energy Sciences in the Department of Energy to investigate a new potential water oxidation system.
Entitled “Development of Earth-Abundant Transition Metal Catalysts for Water Oxidation,” the study will focus on the separation of water into its elements and their recombination to release energy. Using their extensive experience with late first row transition metals (earth abundant) and fluorinated, oxygen donor ligands, the Doerrer Group will prepare new compounds and develop systems leading to a water oxidation catalyst.
The central idea of the research is to incorporate the proven oxidative robustness of fluorinated organic groups into transition metal compounds that will catalyze the oxidation of water to O2. Successful completion of this project will result in one or more new catalysts made with earth abundant materials for oxygen evolution. These compounds will also provide scientists with increased detailed understanding of the fundamental process of water oxidation and how it can be harnessed for environmentally sustainable energy use.
It is with great pleasure that the Department of Chemistry welcomes three new Assistant Professors to our faculty.
Professor Doerrer is a synthetic inorganic chemist. She received her Ph.D. in 1996 from the Massachusetts Institute of Technology, working with Professor Stephen Lippard. She was appointed a NATO Postdoctoral Fellow from 1996 to 1997 in the laboratory of Malcolm Green at Oxford University, followed by a Junior Research Fellowship with him from 1997 to 1999. Linda joined the faculty of Barnard College in 1999 and developed a research program that earned her awards from the National Science Foundation, the Camille and Henry Dreyfus Foundation, the Petroleum Research Fund, among others. In 2002 Barnard recognized her teaching excellence by giving her the Emily Gregory Award for Excellence in Teaching and Service. Linda’s current research interests include synthetic inorganic and organometallic solution phase molecules; perfluorinated aryl rings in weakly coordinated anions, and metallophilic interactions with precious metal double salts.
Professor Xia is joint faculty member in the Boston University Bioinformatics Program and the Department of Chemistry. He received his Ph.D. in 2003 from Stanford University, working with Professor Michael Levitt. He was a Postdoctoral Fellow at Yale University from 2003-2006 with Professor Mark Gerstein. He has been awarded fellowships from both the Jane Coffin Childs Memorial Fund for Medical Research (2004-2006) and the Howard Hughes Medical Institute (1996-2001). Brandon’s research interest is the application of computational techniques to study the structure, function, and evolution of complex bio-molecular systems, such as proteins and protein networks. Specific projects include: reconstruction of protein interaction and regulatory networks by genomic data integration; comparative and evolutionary analysis of proteins and protein networks; protein sequence-structure-function relationships; prediction of protein structure and function,
Professor Reinhard is a physical chemist. He received his Ph.D. in 2004 from the Technische Universität Kaiserslautern working with Professor Gereon Niedner-Schatteburg. He was a Postdoctoral Fellow from 2004-2006 with Professor Jan Liphardt at UC, Berkeley. He is a recipient of the Juan de la Cierva Award (2006) and a DFG Research Scholarship (2005). Björn’s interests are the design, implementation, and characterization of new tools for imaging and manipulation of “hard” (inorganic) and “soft” (biological) materials. One of his aims is to produce hybrid materials that combine interesting electronic/optical properties of inorganic materials with the structural properties of biological materials. He is currently also developing new probes and sensing schemes to characterize the function and dynamics of individual biological molecules and complexes. The ultimate goal of these studies is to generate reliable tools that can grant insight into fundamental biological processes on a single molecule level.
