Among the designed indenopyrazoles ID01–ID33, a series of potent MTAs were identified. As the hydrochloride salt(s), ID09 and ID33 showed excellent aqueous solubility and favorable Log P value and displayed noteworthily low nanomolar potency against a variety of tumor cells, including those taxol-resistant ones. They inhibited tubulin polymerization, disrupted cellular microtubule networks by targeting
以先前发现的1-甲基-1,4-二氢茚并[1,2 c ]吡唑衍生物LL01为先导,对苯酚的6位和7位和苯胺的3位进行了系统的结构修饰。茚并吡唑核用于研究SAR和改善水溶性。在设计的茚并吡唑ID01 - ID33中,鉴定出一系列有效的MTA。作为盐酸盐,ID09和ID33表现出优异的水溶性和良好的Log P并显示出对多种肿瘤细胞(包括那些抗紫杉醇耐药的肿瘤细胞)低的纳摩尔浓度。他们通过靶向秋水仙碱位点抑制微管蛋白聚合,破坏细胞微管网络,并促进HepG2细胞周期阻滞和细胞凋亡。在HepG2异种移植小鼠模型中,ID09和ID33以25 mg / kg的口服剂量有效抑制肿瘤生长。每隔一天静脉注射(iv)10 mg / kg,ID09将肿瘤生长抑制了68%,而没有明显的毒性。
