Fragment-Based NMR Screening of the BPTF PHD Finger Methyl Lysine Reader Leads to the First Small-Molecule Inhibitors.

Methyl lysine readers, specifically PHD fingers, are emerging epigenetic targets in human diseases. For example, several PHD finger fusions are implicated in clinical cases of acute myeloid leukemia, highlighting the potential for PHD inhibitors in disease regulation. However, limited chemical matter targeting PHD fingers exists.

pH Effects Can Dominate Chemical Shift Perturbations in H,N-HSQC NMR Spectroscopy for Studies of Small Molecule/α-Synuclein Interactions.

H,N-Heteronuclear Single Quantum Coherence (HSQC) NMR is a powerful technique that has been employed to characterize small-molecule interactions with intrinsically disordered monomeric α-Synuclein (aSyn). We report how solution pH can impact the interpretation of aSyn HSQC NMR spectra and demonstrate that small-molecule formulations (e.g.

F NMR viewed through two different lenses: ligand-observed and protein-observed F NMR applications for fragment-based drug discovery.

F NMR has emerged as a powerful tool in drug discovery, particularly in fragment-based screens. The favorable magnetic resonance properties of the fluorine-19 nucleus, the general absence of fluorine in biological settings, and its ready incorporation into both small molecules and biopolymers, has enabled multiple applications of F NMR using labeled small molecules and proteins in biophysical, biochemical, and cellular experiments. This review will cover developments in ligand-observed and protein-observed F NMR experiments tailored towards drug discovery with a focus on fragment screening.

New Design Rules for Developing Potent Cell-Active Inhibitors of the Nucleosome Remodeling Factor (NURF) via BPTF Bromodomain Inhibition.

The nucleosome remodeling factor (NURF) alters chromatin accessibility through interactions with its largest subunit,the bromodomain PHD finger transcription factor BPTF. BPTF is overexpressed in several cancers and is an emerging anticancer target. Targeting the BPTF bromodomain presents a potential strategy for its inhibition and the evaluation of its functional significance; however, inhibitor development for BPTF has lagged behind those of other bromodomains.

4-Methyl-1,2,3-Triazoles as -Acetyl-Lysine Mimics Afford Potent BET Bromodomain Inhibitors with Improved Selectivity.

The bromodomain and extra terminal (BET) protein family recognizes acetylated lysines within histones and transcription factors using two N-terminal bromodomains, D1 and D2. The protein-protein interactions between BET bromodomains, acetylated histones, and transcription factors are therapeutic targets for BET-related diseases, including inflammatory disease and cancer. Prior work demonstrated that methylated-1,2,3-triazoles are suitable -acetyl lysine mimetics for BET inhibition.

Journeying through the Field of Medicinal Chemistry: Perspectives from Graduate Researchers.

The training of new medicinal chemists is vital to the future of the field, and as graduate students at this critical stage, we are uniquely positioned to comment on our training. Herein, we discuss the perspectives from graduate researchers before, during, and after graduate school by utilizing survey data obtained from five medicinal chemistry programs in the Midwest and recent alumni of the University of Minnesota. We also reflect on the female perspective within the field of medicinal chemistry.
