an attractive target for selective blockade of viral infection. Previously, we identified a series of sulfones, sulfonamides, and mercaptosalicylhydrazides (MBSAs) as IN inhibitors with antiviral activities in cell-based assays. In an effort to optimize a series of our active site directed lead compounds, we designed and synthesized novel benzodithiazines starting from MBSAs. In contrast to all reported
HIV-1整合酶(IN)是有效进行病毒复制的必需酶,并且是选择性阻断病毒感染的诱人靶标。以前,我们在基于细胞的测定中鉴定了一系列砜,磺酰胺和巯基水杨酰肼(MBSA)作为具有抗病毒活性的IN抑制剂。为了优化我们的一系列活性位点导向的铅化合物,我们设计并合成了从MBSAs开始的新型苯并二噻嗪。与所有报道的IN抑制剂相反,苯并二噻嗪基本上是无毒的。仅在浓度高于抑制纯化的IN所需浓度的条件下,才能观察到显着的抗病毒效力。
