A series of 1-acyl-1H-[1,2,4]triazole-3,5-diamine analogues were synthesized as cyclin-dependent kinase (CDK) inhibitors. These compounds showed potent and selective CDK1 and CDK2 inhibitory activities and inhibited in vitro cellular proliferation in various human tumor cells. Representative compound 3b demonstrated in vivo efficacy in a human melanoma A375 xenograft model in nude mice.

commercially available compounds was conducted with an unbiased approach to identify potential malaria inhibitors that bind to the Plasmodiumfalciparumproteinkinase 5 (PfPK5) ATP‐binding site. PfPK5 is a cyclin‐dependentkinase‐like protein with high sequence similarity to human cyclin‐dependentkinase 2 (HsCDK2), but its precise role in cell‐cycle regulation remains unclear. After two‐dimensional fingerprinting
使用无偏方法对35万种市售化合物进行了计算机筛选,以鉴定与恶性疟原虫蛋白激酶5(Pf PK5)ATP结合位点结合的潜在疟疾抑制剂。P f PK5是一种细胞周期蛋白依赖性激酶样蛋白,与人细胞周期蛋白依赖性激酶2(Hs CDK2)具有高度序列相似性,但其在细胞周期调控中的确切作用尚不清楚。在对得分最高的化合物进行二维指纹图谱分析后,根据其结构多样性对182种候选化合物进行了生化测试的优先级排序。对这些化合物的评估表明,135与Pf PK5的结合程度与已知Pf相似或更好。PK5抑制剂,证实该文库富含Pf PK5结合化合物。分别选择了先前报道的三唑二胺Hs CDK2抑制剂和筛选出的4-甲基伞形酮进行类似物研究。这项研究的结果强调优化难以兼顾Pf的用于PK5亲和力和结合选择性Pf的PK5超过其最接近人类同源HS CDK2。我们的方法能够通过适度的筛选活动发现几种新的Pf PK5结合化合物,并揭示了第一个具有改善的Pf
