soluble oncodazole analogue that could be easily formulated, a series of substituted oncodazoles was synthesized and evaluated for tubulin binding affinity, in vitro cytotoxicity against cultured mouse B-16 cells, and ability to prolong lifespan at the maximally tolerated dose in the P388 mouse leukemia model. Biological evaluation of all the isomeric methyloncodazoles demonstrated the thiophene 4'-position
为了鉴定易于配制的可溶性oncodazole类似物,合成了一系列取代的oncodazoles,并评估了微管蛋白结合亲和力,对培养的小鼠B-16细胞的体外细胞毒性以及在最大耐受剂量下可延长寿命的能力。在P388小鼠白血病模型中。对所有同分异构的甲基oncodazoles的生物学评估表明,噻吩4'-位点是具有显着容忍度的唯一位点,尽管用极性或带电官能团取代了该位点可消除生物学活性。已显示4'-羧甲基oncodazole的简单酯相对于oncodazole具有增强的抗肿瘤活性和微管蛋白结合亲和力。尽管这项研究未能确定具有抗肿瘤活性的水溶性oncodazole,
