A novel series of benzimidazolone-containing histamineH3-receptor antagonists were prepared and their structure–activity relationship was explored. These benzimidazolone analogs demonstrate potent H3-receptor binding affinities, no P450 enzyme inhibition, and strong H3 functional activity. Compound 1o exhibits the best overall profile with H3Ki = 0.95 nM and rat AUC = 12.9 μM h.
制备了一系列新的含苯并咪唑酮的组胺H 3受体拮抗剂,并探讨了它们的结构-活性关系。这些苯并咪唑酮类似物显示出有效的H 3-受体结合亲和力,无P450酶抑制作用,并且具有强大的H 3功能活性。化合物1o表现出最佳的总体特征,H 3 K i = 0.95 nM,大鼠AUC = 12.9μMh。
1-Thiazol-2-yl-N-3-methyl-1H-pyrozole-5-carboxylic acid derivatives as antitumor agents
A class of substituted 1-thiazol-2-yl-N-3-methyl-1H-pyrozole-5-carboxylic acidderivatives was found to have potent anti-proliferative activity against a broad range of tumor cell lines. A compound from this class (14) was profiled across a broad panel of hematologic and solid tumor cancer cell lines demonstrating cell cycle arrest at the G0/G1 interphase and has potent anti-proliferative activity

We disclose further optimization of hydantoin TNF-α convertase enzyme (TACE) inhibitors. SAR with respect to the non-prime region of TACE active site was explored. A series of biaryl substitutedhydantoincompounds was shown to have sub-nanomolar Ki, good rat PK, and good selectivity versus MMP-1, -2, -3, -7, -9, and -13.
