A series of steroid and azasteroid analogues containing a six-membered ring A with various functionalities were synthesized. Furthermore, the syntheses of tetracyclic analogues bearing a five-membered A-ring and the syntheses of a number of bicyclic secosteroid analogues were carried out. All compounds were tested for their antibacterial, antifungal and cytotoxic activities. Among all tested compounds
合成了一系列包含具有各种功能的六元环A的类固醇和氮杂类固醇类似物。此外,进行了带有五元A环的四环类似物的合成以及许多双环类固醇类固醇类似物的合成。测试所有化合物的抗菌,抗真菌和细胞毒性活性。在所有测试的化合物中,7和9表现出杰出的细胞毒性活性,但没有抗微生物活性。化合物的细胞毒性活性7,9和10最初是由美国国家癌症研究所(NCI)在单剂量60细胞试验验证。根据我们的结果7和9 满足了进行5剂量NCI筛选的预定阈值抑制标准,该标准揭示了这两种候选药物的选择性活性谱。
