The Malcolmson lab has recently shown that gem-difluoroazadienes can serve as a novel building block for the synthesis of chiral alpha-trifluoromethyl amines via the vicinal fluoro-functionalization of its alkene. Alpha-trifluoromethyl amines are important medicinal motifs as the CF3 group serves as a proteolysis-resistant surrogate for an amide. In this work, the research team has demonstrated that AgF addition across the azadiene is catalyzed by a phosphine, leading to a metastable alpha-CF3 azaallyl–silver… read more about Malcolmson Lab Demonstrates New Route to Alpha-Trifluoromethyl Amines »

Agostino Migliore, Darius Teo and additional members of the Beratan Lab, with collaborators at USC, take an important step towards understanding intracellular redox signaling at the core of DNA repair and replication processes. Experiments suggesting a role for DNA charge transport in mediating such signaling have been the subject of a heated debated in recent literature. The lab has demonstrated that charge transfer between a [4Fe4S] protein and a nucleic acid duplex is unidirectional. This… read more about Unraveling Important Constraints on the Mechanisms for Redox Signaling in DNA Replication and Repair »

The static correlation error inherent in commonly used density functional approximations (DFAs) has seriously hindered the application of density functional theory (DFT) to strongly correlated systems. Here, an effective fractional-spin correction against the important issue of static/strong correlation in DFT is developed. With this, the flat-plane behavior of various DFAs is largely restored, and the potential energy curves of dissociation of ionic species, single bonds, and multiple bonds are properly described, which… read more about Yang Lab Describing Correlation with Fractional-spin Correction in DFT »

While the majority of small molecule chemical probes and drugs to date modulate the action of proteins, the Hargrove Lab is searching for small molecules that selectively engage binding pockets of RNA. In their most recent work, the group discovered the first ligands for the triple helix structure of an oncogenic long non-coding RNA MALAT1. The synthesis, evaluation and computational analysis of these novel small molecules revealed trends between small molecule shapes and their binding behavior. Together, these… read more about Hargrove Lab Searches for Small Molecules that Selectively Engage Binding Pockets of RNA »

The enantioselective and intermolecular addition of nucleophiles to internal olefins is a challenging process due to the typically low reactivity of these substrates. Hydroaminations of 1,4-disubstituted dienes present further challenges as several product regioisomers may be obtained and reactions tend to be reversible, leading to erosion of enantiopurity of products over time. The Malcolmson lab has now demonstrated that Pd–PHOX catalysts facilitate the regio- and enantioselective hydroamination of internal dienes with… read more about Malcolmson Lab Illustrates Enantioselective Hydroamination of Internal Dienes »

Non-coding RNAs have been identified that are essential for cellular regulation and that are misregulated in disease; however, the development of tools to study these RNAs has been challenging. To harness existing knowledge into the development of RNA-targeted chemical probes, the Hargrove lab examined the RNA targets, design and discovery strategies, and characterization techniques for ligands in the RNA-targeted BIoactive ligaNd Database (R-BIND).  Further, the survey… read more about Hargrove Lab Hopes to Expedite the Discovery of RNA-targeted Ligands »

Duke Chem alumni reunited at the University of Notre Dame for the Biennial Conference on Chemical Education! Drs. Robert Harris (Emory University), Jennifer Hawk (Converse College), and Pam Mosley (Michigan State) joined Dr. Kathryn Haas (St. Mary's College) to present talks, posters and Chair sessions.  Dr. James Parise (Univ. of Notre Dame) Co-Chaired the Conference.    read more about Alumni Reunited at the University of Notre Dame for the Conference on Chemical Education »

GGTDTC, a copper prochelator of dithiocarbamate was developed to release dithiocarbamate (DTC) in cancer expressing gamma-glutamyl transferase enzyme. Upon release DTC is free to bind to Cu to form toxic Cu(DTC)2 . GGTDTC was found to selectively release diethyldithiocarbamate only in prostate cancer cells with measurable gamma-glutamyl transferase activity.  These findings underscore a new strategy to leverage the amplified copper metabolism of prostate cancer by conditional activation of a metal‐binding… read more about Franz Lab Combating Prostate Cancer One Metal at a Time »

Professor Jennifer Roizen has received a Maximizing Investigator’s Research Award (R35).  Professor Roizen’s research under this award will enable chemists to harness a ubiquitous functional group, the alcohol, to replace a C–H bond at a site that is not generally accessible to direct functionalization, and is expected to streamline access to biologically under-evaluated health-relevant small molecules. Congratulations to Jenny and her research group on receipt of this prestigious award (and her… read more about Jennifer Roizen Receives NIH MIRA Award! »

The Charbonneau lab is bringing together researchers from industry and academia to develop a tool for automatizing protein crystal recognition.  Scientists came together to collect half a million images of protein crystallization experiments into a database that can specify which of these protein cocktails led to crystallization, based on human evaluation. The team then worked with a group led by Vincent Vanhoucke from Google Brain to apply the latest in artificial intelligence to help identify crystals in… read more about Charbonneau Lab Using A.I. to Recognize Crystals in Protein Crystallization Experiments »

Building upon their initial work illustrating the use of 2-azadienes for the enantioselective synthesis of challenging amine scaffolds, the Malcolmson lab has now reported that these reagents may engage in reductive couplings with imines for the synthesis of anti-1,2-diamines.  The Cu-catalyzed process is highly chemo-, diastereo-, and enantioselective for the preparation of a range of diamines, including those that have largely remained elusive until now.  The authors additionally highlight the… read more about Malcolmson Lab Demonstrates Reductive Coupling Strategy for 1,2-Diamine Synthesis »

The Franz Lab and collaborators explored the antibacterial mechanism of PcephPT, a prodrug of the antimicrobial chelator pyrithione.  Graduate students Jacqueline Zaengle-Barone and Abigail Jackson and former grad student David Besse found that PcephPT has an unconventional mode of action, requiring β-lactamase expression and copper availability for maximal activity. This “prochelator" overcomes the liability of metal chelation toxicity because it does not chelate metal ions until specifically… read more about Franz Lab Demonstrates Copper’s Role in Antibacterial Mechanism of a Prochelator »
