Since the beginning of the HIV epidemic almost 70 million people have been infected with HIV. It is estimated that 42 million people are currently living with HIV/AIDS. The spread of HIV continues throughout the world and current estimates indicate that in 2002, 5 million people were newly infected with HIV and 3 million people died. Current treatments employ a combination of therapeutic agents that target the viral reverse transcriptase and protease enzymes and viral entry. However the clinical benefit of these agents is often limited due to issues of regimen compliance, significant side effects, and the emergence of viral strains that are drug resistant. The introduction of novel agents that interfere with alternate stages in the viral life cycle represent potential solutions to these problems. The integration of the HIV genome into the cellular chromosome, a process catalyzed by the viral enzyme integrase, has been shown to be essential for viral replication. Since HIV integrase has no direct cellular counterpart it presents itself as an attractive target for therapeutic intervention. This review summarizes recent and promising developments both in the HIV integrase field and the global quest for therapeutically useful inhibitors of HIV integrase.
自艾滋病流行开始以来,近7000万人感染了艾滋病毒。据估计,目前有4200万人感染艾滋病毒/艾滋病。艾滋病毒在全球范围内继续传播,目前的估计表明,2002年有500万人新感染艾滋病毒,300万人死亡。目前的治疗方法采用多种治疗药物的组合,这些药物靶向病毒逆转录酶、蛋白酶以及病毒进入过程。然而,由于治疗方案依从性问题、严重的副作用以及耐药病毒株的出现,这些药物的临床益处往往受到限制。引入干扰病毒生命周期不同阶段的新型药物可能解决这些问题。艾滋病毒基因组整合到细胞染色体中,这一过程由病毒整合酶催化,已被证明对病毒复制至关重要。由于艾滋病毒整合酶在细胞中没有直接对应的酶,它成为治疗干预的一个有吸引力的靶点。本综述总结了艾滋病毒整合酶领域近期有前景的进展以及全球对治疗性有用的艾滋病毒整合酶抑制剂的探索。
