For most viruses,there is aneed for antimicrobials that target unique viral molecular properties.Acycloviris one such drug.It is activated into ahuman herpesvirusDNA polymerase inhibitor exclusively by HHV kinases and,thus,does not suppress other viruses.Here,we show that ACV suppresses HIV-1in HHV-coinfected human tissues,but not in HHV-free tissue or cell cultures.However,addition of HHV-6-infected cells renders these cultures sensitive to anti-HIV ACV activity.We hypothesized that such HIV suppression requires ACV phosphorylation by HHV kinases.Indeed,an ACV monophosphorylated prodrug bypasses the HHV requirement for HIV suppression.Furthermore,phosphorylated ACV directly inhibits HIV-1reverse transcriptase,terminating DNA chain elongation,and can trap RT at the termination site.These data suggest that ACV anti-HIV-1activity may contribute to the response of HIV/HHV-coinfected patients to ACV treatment and could guide strategies for the development of new HIV-1RT inhibitors.

对大多数病毒而言，都需要有针对其分子特性的靶向杀毒剂阿昔洛韦就是这样一种靶向药物在人疱疹病毒酶的特定作用下，阿昔洛韦被激活成为人疱疹病毒DNA聚合酶抑制剂，因此不能再抑制其它的病毒我们的研究发现阿昔洛韦在共感染人疱疹病毒的组织中可以抑制HIV-1，但在无人疱疹病毒感染的组织或细胞中无此作用然而，加入人疱疹病毒-6感染的细胞却使得其对抗HIV的阿昔洛韦变得敏感我们推测这种抑制作用依赖于人疱疹病毒酶导致的阿昔洛韦磷酸化实际上，单磷酸化的阿昔洛韦前体药物无需人疱疹病毒的参与即可抑制HIV此外，磷酸化的阿昔洛韦能直接抑制HIV-1逆转录酶，将其阻止在终止位点，从而终止DNA链的延长这些结果提示阿昔洛韦的抗HIV-1活性决定了艾滋病病毒/人疱疹病毒共感染的患者对阿昔洛韦的治疗反应，也有助于开发新的HIV-1逆转录酶抑制剂
