cellular processes. Most small‐molecule PARP inhibitors developed to date have been against PARP1, and suffer from poor selectivity. PARP14 has recently emerged as a potential therapeutic target, but its inhibitor development has trailed behind. Herein, we describe a smallmolecule microarray‐based strategy for high‐throughput synthesis, screening of >1000 potential bidentate inhibitors of PARPs, and the
μM), which was more potent than PCI-34058 (6) (IC50 = 0.31 μM), a known HDAC8 inhibitor. Molecular modeling suggested that the phenylthiomethyl group of C149 binds to a unique hydrophobic pocket of HDAC8, and the orientation of the phenylthiomethyl and hydroxamate moieties (fixed by the triazole moiety) is important for the potency and selectivity. The inhibitors caused selective acetylation of cohesin

Challenges exist in the development of potent and selective small‐molecule inhibitors against caspase‐1. Herein, by making use of the copper‐free strain‐promoted alkyne–azide cycloaddition (SPAAC) reaction between difluorinated cyclooctynes (DIFOs) and various azide‐containing compounds, we showed for the first time that potential caspase‐1 inhibitors could be rapidly synthesized. The resulting fused

the biological functions of the isoforms and as therapeutic agents for cancer and neurodegenerative disorders. To discover potent and selective inhibitors, we screened a focused library synthesized by using clickchemistry and obtained KPZ560 as an HDAC1/2-selective inhibitor. Kinetic binding analysis revealed that KPZ560 inhibits HDAC2 through a two-step slow-binding mechanism. In cellular assays
