An efficient method for the conversion of available plant allylpolyalkoxybenzenes into unsubstituted and arylsubstituted polymethoxylated aryldihydrobenzo[g]indazoles, analogues of combretastatin A4, has been developed. The selective demethylation of target compounds resulted in indazoles with different position of OH-group. Their structure was confirmed by X-ray analysis. A sea urchin embryo assay
已开发出一种将可用的植物烯丙基聚烷氧基苯转化为未取代和芳基取代的聚甲氧基化芳基二氢苯并[ g ]吲唑(combretastatin A4 的类似物)的有效方法。目标化合物的选择性去甲基化导致具有不同 OH 基团位置的吲唑。它们的结构通过X射线分析得到证实。海胆胚胎试验表明,芳基二氢苯并 [g] 吲唑缺乏与微管蛋白相关的抗有丝分裂活性,具有 OH 基团和 1-未取代吡唑环化合物的全身毒性。
