natural nucleoside or nucleoside inhibitors. In the present study, we have explored the possibility to find a new lead molecule based on α-pyrone analogs as non-nucleoside inhibitors using structure based modeling approach. The designed molecules were synthesized and evaluated for anti-HSV activity using MTT assay. The compound 5h with EC50 7.4 μg/ml and CC50 52.5 μg/ml was moderately active against HSV
有几种治疗1型和2型单纯疱疹病毒的选择。然而,非特异性抑制和耐药性保证了新的抗疱疹性化合物具有更好的治疗特性或不同的作用方式的发现。HSV DNA聚合酶的非核苷抑制剂靶向的位点对于天然核苷或核苷抑制剂的结合而言并不重要。在本研究中,我们已经探索了使用基于结构的建模方法寻找基于α-吡喃酮类似物作为非核苷抑制剂的新先导分子的可能性。合成设计的分子,并使用MTT分析评估其抗HSV活性。化合物5h的EC 50 7.4μg/ ml和CC 50与阿昔洛韦相比,52.5μg/ ml对HSV具有中等活性。还进行了噬斑减少试验,结果显示5h对HSV-1更有效,选择性指数为12.8,比对HSV-2更好(SI = 3.6)。还评估了合成的化合物的抗HIV活性,但没有一个具有活性。
