A series of tetrazoles linked to the butenolide core via benzene rings were prepared by the Stille coupling reaction of α-(tributylstannyl)butenolides and 5-(alkylsulfanyl)-1-(4-iodophenyl)tetrazoles, and the compounds were tested for antifungal and cytostatic activity. Interesting antifungal activities against the filamentous strain Absidia corymbifera, and cytostatic activities against leukemic cells HL-60 and CCRF-CEM were found. The cytostatic activity requires the presence of both the butenolide ring and the alkylsulfanyl group bound to tetrazole ring. In addition, the feasibility of Pd-coupling reactions with 5-iodotetrazoles was evaluated.
一系列通过苯环连接到丁烯内酯核心的四唑类化合物,是通过α-(三丁基锡基)丁烯内酯和5-(烷基硫基)-1-(4-碘苯基)四唑的斯蒂尔偶联反应制备的,并且对这些化合物进行了抗真菌和细胞毒活性测试。有趣的抗真菌活性针对丝状菌株Absidia corymbifera,以及对白血病细胞HL-60和CCRF-CEM的细胞毒活性被发现。细胞毒活性需要丁烯内酯环和连接到四唑环的烷基硫基团同时存在。此外,还评估了与5-碘四唑进行Pd偶联反应的可行性。
