Indole derivatives and analogous compounds and pharmaceutical compositions comprising the same are provided. Also provided are methods of using these compounds to inhibit tubulin polymerization in a cell associated with a proliferative disease or to treat cancer, metastatic cancer, resistant cancer or multidrug resistant cancer, including inter-alia: prostate cancer, breast cancer, melanoma, colon cancer and bladder cancer.

new analogs have comparable potency to the most active compounds in the previous set when tested in two melanoma and four prostate cancer cell lines. These SAR studies indicated that the antiproliferativeactivity was very sensitive to subtle changes in the ligand. Tested compounds 3ab and 8a are equally active against highly paclitaxel resistant cancer cell lines and their parental cell lines, indicating
我们之前报道了 2-芳基-4-苯甲酰基-咪唑 (ABI-I) 作为黑色素瘤的有效抗增殖剂的发现。为了进一步了解 ABI 类似物效力的结构要求、深入了解构效关系 (SAR) 并研究这些化合物的代谢稳定性,我们报告了对 ABI-I 支架的广泛 SAR 研究。与前一组 ABI-I 类似物相比,新合成的 ABI-II 类似物总体上具有较低的效力,但当在两个黑色素瘤和四个前列腺中进行测试时,一些新类似物的效力与前一组中最活跃的化合物相当癌细胞系。这些 SAR 研究表明抗增殖活性对配体的细微变化非常敏感。测试化合物3ab和8a对紫杉醇高度耐药的癌细胞系及其亲代细胞系同样具有活性,表明基于 ABI-I 类似物开发的药物在治疗耐药肿瘤方面可能比紫杉醇具有治疗优势。化合物3ab 的代谢稳定性研究表明,N-甲基咪唑未能像文献报道的那样延长稳定性,因为去甲基化被发现是大鼠和小鼠肝微粒体中的主要代谢途径。然而,这
