A new series of HIV-1 fusion inhibitors and methods of use are disclosed. The compounds are based on a substituted indole, benzimidazole, indoline or isoindoline fragment. The compounds find use in inhibiting or preventing HIV fusion from occurring, thus inhibiting or preventing entry of viral RNA into host cells. The compounds may be useful towards other biological targets involving protein-protein interactions.

strongly correlated to fusion inhibitory data (R2 = 0.91), and corresponding inhibition of viral replication confirmed the hydrophobic pocket as a valid target for low molecular weight fusioninhibitors. The most active compound bound to the hydrophobic pocket and inhibited cell–cell fusion and viral replication at submicromolar levels. A common binding mode for the inhibitors in this series was established
融合的非肽抑制仍然是抗 HIV 研究的一个重要目标,因为它具有低成本预防或预防病毒细胞间传播的潜力。我们在此报告了一系列已通过基于结构的药物设计方法鉴定为 gp41 融合抑制剂的吲哚化合物。化合物对疏水袋的实验结合亲和力与融合抑制数据密切相关 ( R 2= 0.91),相应的病毒复制抑制证实了疏水袋是低分子量融合抑制剂的有效靶点。最活跃的化合物与疏水袋结合,并以亚微摩尔水平抑制细胞 - 细胞融合和病毒复制。通过使用蛋白质数据库中的 gp41 结构进行对接研究,建立了该系列抑制剂的常见结合模式。分子足够灵活以符合口袋的轮廓,最活跃的化合物能够采用模拟 D 肽 PIE7 疏水接触的结构。结果增强了我们对吲哚化合物作为 gp41 抑制剂的理解。
