TL;DR: It is demonstrated that S63845 potently kills MCL1-dependent cancer cells, including multiple myeloma, leukaemia and lymphoma cells, by activating the BAX/BAK-dependent mitochondrial apoptotic pathway.

TL;DR: The structure-based design, synthesis, structure-activity relationships and pharmacokinetics of potent small-molecule inhibitors of Hsp90 based on the 4,5-diarylisoxazole scaffold are described and analogues from this series have high affinity for HSp90, as measured in a fluorescence polarization (FP) competitive binding assay, and are active in cancer cell lines.

TL;DR: This work illustrates how virtual screening can identify a diverse set of ligands which bind to the targeted site, and the structural models for these ligands in the Chk1 ATP-binding site will facilitate further medicinal chemistry efforts targeting this kinase.

TL;DR: The structures of the HSP90alpha N-terminal domain complexed with the purine-based inhibitor, PU3, and analogs with enhanced potency both in enzyme and cell-based assays confirm that the molecules inhibit cell growth by a mechanism dependent on H SP90 inhibition.

TL;DR: The crystal structure of a previously reported screening hit 1 (CCT018159) bound to the N terminal domain of molecular chaperone Hsp90 has been used to design 5-amide analogues that exhibit enhanced potency against the target in binding and functional assays with accompanying appropriate cellular pharmacodynamic changes.
