Lycogarubin C, permethyl storniamide A, and lamellarin G trimethyl ether are pyrrole containing, natural products, which exhibit interesting biological properties. Such properties include anti-tumor activity on a variety of cancer cell lines including those that confer drug resistance, inhibition of HIV integrase, and vascular disrupting activity. We now describe the use of methyl and ethyl 3-brom
Lycogarubin C,permethyl storniamide A和lamellarin G三甲基醚是含有吡咯的天然产物,具有令人感兴趣的生物学特性。这些特性包括对多种癌细胞系的抗肿瘤活性,包括赋予耐药性,抑制HIV整合酶和血管破坏活性的癌细胞系。现在我们描述使用甲基和3-溴-2-甲酰基吡咯-5-羧酸甲酯和乙酯作为这三种高度官能化的生物活性吡咯的正式合成的基础。由于能够轻松修改吡咯核心的位置2、3、4和5,这些新的构建基块现在将提供对天然产物和许多新颖类似物的便捷访问。
