The synthesis and the evaluation of cytotoxicity and anti-HIV-1 activity of new aryl pyrrolyl (8) and aryl indolyl (9) sulfones are reported. Preparation of above sulfones was achieved by reacting arylsulfonyl chlorides with substituted pyrroles and indoles or by condensing sulfonamides with 2,5-dimethoxytetrahydrofuran in glacial acetic acid according to the Clauson-Kaas method. Chemical requisites
据报道合成了新的芳基吡咯基(8)和芳基吲哚基(9)砜,并对其细胞毒性和抗HIV-1活性进行了合成和评估。根据Clauson-Kaas方法,通过使芳基磺酰氯与取代的吡咯和吲哚反应,或通过将磺酰胺与2,5-二甲氧基四氢呋喃在冰醋酸中缩合,来制备上述砜。与这些化合物的抗HIV-1活性有关的化学要求是2-磺酰基-4-氯苯胺基部分和吡咯环2位的烷氧羰基。用乙氧基羰基和异丙氧基羰基取代基获得最佳的活性和选择性。药效基团部分的氨基取代导致无活性的产物(烷基化)或减弱的(酰化)抗HIV-1活性。在测试衍生物中,16种化合物的EC50值在10至1 microM之间,五种(8b',d',f',h'j')的EC50S在亚微摩尔范围内。这些化合物对野生型和AZT耐药菌株的HIV-1有活性,但对HIV-2没有活性。此外,在酶分析中,它们有效抑制了HIV-1重组逆转录酶,对耐奈韦拉平和TIBO耐药菌株的酶活性降低了1
