A SAR study has been performed in order to evaluate how much the ester function could be a determinant for the anti-human immunodeficiency virus type-1 activity of pyrryl aryl sulfones (PASs), a potent family of non-nucleoside reverse transcriptase (RT) inhibitors discovered in the last years. Twenty-three new esters were prepared with the aim to enhance the inhibitory potency of 4a and 4c, two PAS agents endowed with good activity (EC50 = 0.14 microM) and deprived of cytotoxicity up to >200 microM. None of test derivatives was as potent as 4a and 4c and lacked of selectivity due to their higher cytotoxicity (compounds 22-25). Antiviral activity correlate with an ester ramified chain.
为了评估酯官能团对吡咯芳基砜(PASs)抗人免疫缺陷病毒1型活性的影响程度,开展了一项构效关系(SAR)研究。PASs是近年来发现的一类有效的非核苷逆转录酶(RT)抑制剂。制备了23种新的酯,目的是提高4a和4c的抑制效力,这两种PAS药物具有良好的活性(EC50 = 0.14 microM),且在高达>200 microM时无细胞毒性。测试的衍生物均不如4a和4c有效,并且由于细胞毒性较高(化合物22 - 25)而缺乏选择性。抗病毒活性与酯的支链有关。
