The pyridine alkaloid niphatesine C and its analogue norniphatesine C were prepared in a short and efficient way starting from commercially available 3‐iodopyridine and undec‐10‐yn‐1‐ol using a Sonogashira reaction as the key step. The resulting alkylpyridines were tested for antimicrobial activity against several bacteria and fungi. The cytotoxic activities were determined in the MTT assay against
以市售的 3-碘吡啶和 undec-10-yn-1-醇为原料,以 Sonogashira 反应为关键步骤,以一种简短有效的方式制备了吡啶生物碱 niphatesine C 及其类似物去甲硝基苯甲酸 C。测试所得烷基吡啶对几种细菌和真菌的抗微生物活性。在 MTT 试验中测定了对 HL 60 细胞的细胞毒活性。
