摘要
目前,使用的抗逆转录病毒HIV治疗药物专门针对病毒生命周期必需的酶中的关键组。其基因突变的增加改变了这些病毒酶,这些酶一旦发生突变就可以逃避治疗靶向,这种效应可以提供抗药性。为了避免这种情况,我们的研究解决了设计和衍生HIV-Integrase(HIV-IN)抑制剂的策略,该抑制剂同时靶向两个IN功能域,即使酶积累了许多突变也使其失活。首先,我们回顾IN的酶促作用,将复制的病毒DNA插入宿主T淋巴细胞的染色体中,突出其主要功能和结构特征,使其受到抑制作用。从功能和结构的角度来看,我们提出了所有类别的HIV-IN抑制剂及其最具代表性的候选者。对于每种选择的化合物,我们还解释了其抑制IN的机制。我们使用最近解析的冷冻EM IN四聚体来自DNA复合物,在其上我们对接各种参考IN抑制性化学支架,例如靶向相邻的功能性IN结构域。配对具有互补活性的化合物,它们停靠在IN结构微域的附近,我们设计了双功能新药,它们不仅对IN突变更具弹性,而且可能是比原始对应物更有效的抑制剂。在我们的综述结束时,我们提出了将这些配对化合物与增强的协同IN抑制作用联系起来的合成途径。
