Griseofulvin may combine with tubulin as a component of microtubules and, at high doses, inhibits microtubule formation in mammalian cells. In this study, the author examined the effects of three various 2'-substitutive derivatives of griseofulvin on microtubule distribution in Chinese hamster V79 cells. The results showed that 2'-demethoxy-2'propoxygriseofulvin was the strongest inhibitor of a normal cytoplasmic microtubule network, unlike findings in previous in-vitro studies.
灰黄霉素可能与作为微管成分的微管蛋白结合,并且在高剂量时抑制哺乳动物细胞中的微管形成。在本研究中,作者检测了灰黄霉素的三种不同的2'-取代衍生物对中国仓鼠V79细胞中微管分布的影响。结果显示,与之前的体外研究结果不同,2'-去甲氧基-2'-丙氧基灰黄霉素是正常细胞质微管网络的最强抑制剂。
