A series of 2-arylamino-5-(indolyl)-1,3,4-thiadiazoles as potent cytotoxic agents
摘要:
A series of 2-arylamino-5-(indolyl)-1,3,4-thiadiazoles 6a-v were prepared and studied for their anticancer activity against selected human cancer cell lines. The reaction of indolylhydrazides 3a-h with a variety of aryl isothiocyanates 4 afforded the key intermediate thiosemicarbazides 5a-v, which upon treatment with acetyl chloride produced the 2-arylamino-5-(indolyl)-1,3,4-thiadiazoles 6a-v in good yields. Most of the synthesized compounds showed selective cytotoxicity towards human breast cancer cell line (MDA-MB-231). Of the synthesized 2-arylamino-5-(indolyl)-1,3,4-thiadiazoles, compound 6f is the most potent towards tested cancer cell lines (IC50 = 0.15-1.18 mu M). (C) 2012 Elsevier Masson SAS.

A series of new indolyl‐1,3,4‐oxadiazole derivatives 3, 4, 5, 6, 7 and 10, indolyl‐1,2,4‐triazole derivatives 14 and 15 was prepared, using 1‐(4‐methoxybenzyl)‐1H‐indole‐3‐carbohydrazide (2) as a key intermediate. Some of the new compounds were evaluated for their antineoplastic activity.
一系列新的吲哚基1,3,4-恶二唑衍生物的3,4,5,6,7和10,吲哚基-1,2,4-三唑衍生物14和15制备,使用1-(4-甲氧基苄基) ‐1 H ‐吲哚-3-碳酰肼(2)作为关键中间体。对一些新化合物的抗肿瘤活性进行了评估。
