anti-tumor agents. Several thiazolo-, pyrido-, pyrano- and lactam steroidderivatives were obtained using 17β-hydroxy-5α-androstan-3-one (androstanolone) 1 as starting steroid. The structure of the novelsteroidderivatives was confirmed using the analytical and spectral data. The most pure and structurally promising compounds 7a, 10a, 12b, 18 and 23 were evaluated as anti-tumor agents. The in vitro
本研究的目的是合成和评估新的潜在化疗抗肿瘤药物。使用17β-羟基-5α-雄烷-3-酮(雄甾烷酮)1作为起始类固醇,获得了几种噻唑基,吡啶基,吡喃基和内酰胺类固醇衍生物。使用分析和光谱数据证实了新型类固醇衍生物的结构。最纯净且结构上最有前景的化合物7a,10a,12b,18和23被评估为抗肿瘤药物。使用MTT测定法评估了针对肝癌细胞系的体外细胞毒性活性。还评估了针对艾氏腹水癌(EAC)的体内抗肿瘤活性。体外研究结果表明,在橄榄油中孵育72小时后,化合物7a是最有效的细胞毒性化合物,IC 50为30μM,而化合物18和23的作用与IC 50为37大致相似μM和35μM。当测试化合物溶于DMSO时,在48 h和72 h孵育期间显示出大约相同的IC 50,而化合物23是最有效的细胞毒性药物,在48小时时IC 50为42μM,在72小时时为40μM。体内研究的结果表明,所有测试的25 mg / kg
