Antiproliferative 4-(1,2,4-oxadiazol-5-yl)piperidine-1-carboxamides, a new tubulin inhibitor chemotype
摘要:
We discovered a new chemical class of antiproliferative agents, 4-(1,2,4-oxadiazol-5-yl)piperidine-1-carboxamides. SAR-guided optimization of the two distinct terminal fragments yielded a compound with 120 nM potency in an antiproliferative assay. Biological activity profile studies (COMPARE analysis) demonstrated that 4-(1,2,4-oxadiazol-5-yl)piperidine-1-carboxamides act as tubulin inhibitors, and this conclusion was confirmed via biochemical assays with pure tubulin and demonstration of increased numbers of mitotic cells following treatment of a leukemia cell line.

initio molecular orbital calculations combined with qualitative estimates of steric interaction energies suggest that the lowest energy conformations of the acyloxyamidine linker are characterized by an extended planar CAr-C=N-O-C arrangement and either a syn-periplanar or anti-periplanar N-O-C-C(Ar') arrangement. Only the anti-periplanar conformation was observed in the crystalstructures of three

The central CB2 receptor represents a promising target for the treatment of neuroinflammatory diseases as CB2 activation mediates anti-inflammatory effects. Recently, the F-18 labeled PET radiotracer [18F]7a was reported, which shows high CB2 affinity and high selectivity over the CB1 subtype but low metabolic stability due to hydrolysis of the amide group. Based on these findings twelve bioisosteres

the other channels tested, and modest improvements in metabolic clearance. Analog VU0935685 represents a new, structurally distinct small-molecule inhibitor of SLACK channels that can serve as an in vitro tool for studying this target.
Discovery of 4-(1,2,4-Oxadiazol-5-yl)azepan-2-one Derivatives as a New Class of Cannabinoid Type 2 Receptor Agonists for the Treatment of Inflammatory Pain
attractive therapeutic strategy for the treatment of inflammatory pain without psychiatric side effects mediated by the cannabinoid receptor CB1. Herein, we report the discovery of 4-(1,2,4-oxadiazol-5-yl)azepan-2-one derivatives as a new class of CB2 agonists. Systematic structure–activity relationship investigations resulted in the identification of the most potent compound 25r. This compound displayed high
