Abstract By the reaction of 3-[(furan-2-ylmethyl)sulfanyl]propanoylhydrazide with various isothiocyanates, the corresponding 4-substituted 1-[(furan-2-ylmethyl)sulfanyl] propanoylthiosemicarbazide derivatives (2–5) were obtained. Thiosemicarbazide derivatives (2–5) by ring closure with 2% NaOH, provided 5-2-[(furan-2-ylmethyl)sulfanyl]ethyl}-4-substituted-2,4-dihydro-3H-1,2,4-triazole-3-thiones (6–9)
摘要 通过3-[(呋喃-2-基甲基)硫烷基]丙酰肼与各种异硫氰酸酯反应,得到相应的4-取代1-[(呋喃-2-基甲基)硫烷基]丙酰氨基硫脲衍生物(2-5)。氨基硫脲衍生物 (2-5) 通过用 2% NaOH 闭环,提供 5-2-[(呋喃-2-基甲基)硫烷基]乙基}-4-取代的-2,4-二氢-3H-1,2, 4-三唑-3-硫酮 (6-9)。测试了新化合物的体外抗微生物活性。化合物 2、3 和 6 对革兰氏阳性细菌参考菌株具有体外活性,MIC 值:250–500 μg/mL(对于化合物 2)、125–250 μg/mL(对于化合物 3)、500–1000 μg/mL(对于化合物 6)。[本文提供补充材料。转至出版商的在线版 Phosphorus, Sulfer,
