  摘要：

  根据来自大量HIV-1整合酶抑制剂的数据，可以观察到相似的结构特征，该特征由两个被中央连接子分隔的芳基单元组成。对于许多符合这种模式的抑制剂，至少一个芳基环也需要邻双羟基化以显着抑制作用。这类邻苯二酚物质原位氧化成反应性醌的能力对其实用性提出了一种潜在的限制。为了解决这个问题，制备了一系列不含邻双羟基的抑制剂。这些类似物均未显示出明显的抑制作用。因此，采取了另一种方法，其目的是增加效力而不是消除儿茶酚的亚结构。在后面的研究中，萘核被用作芳基成分，因为先前的报告已经表明，相对于基于单环苯基的系统，稠合的双环可能具有更高的亲和力。在单体单元的初步工作中，发现6,7-二羟基-2-萘甲酸（17）（IC50 = 4.7 microM）的效力比其5,6-二羟基异构体19（IC50 = 62.4微米）。特别值得注意的是，游离酸17和其甲酯21的效价之间存在巨大差异（IC50> 200 microM）。由

  Efficient replication of HIV-1 requires integration of a DNA copy of the viral genome into a chromosome of the host cell. Integration is catalyzed by the viral integrase, and we have previously reported that phenolic moieties in compounds such as flavones, caffeic acid phenethyl ester (CAFE, 2), and curcumin confer inhibitory activity against HIV-1 integrase. We now extend these findings by performing a comprehensive structure-activity relationship using CAPE analogues. Approximately 30 compounds have been prepared as HIV integrase inhibitors based on the structural lead provided by CAPE, which has previously been shown to exhibit an IC50 value of 7 mu M in our integration assay. These analogues were designed to examine specific features of the parent CAFE structure which may be important for activity. Among the features examined for their effects on inhibitory potency were ring substitution, side chain length and composition, and phenyl ring conformational orientation. In an assay which measured the combined effect of two sequential steps, dinucleotide cleavage and strand transfer, several analogues have IC50 values for 3'-processing and strand transfer lower than those of CAFE. Inhibition of strand transfer was assayed using both blunt-ended and ''precleaved'' DNA substrates. Disintegration using an integrase mutant lacking the N-terminal zinc finger and C-terminal DNA-binding domains was also inhibited by these analogues, suggesting that the binding site for these compounds resides in the central catalytic core. Several CAFE analogues were also tested for selective activity against transformed cells. Taken together, these results suggest that the development of novel antiviral agents for the treatment of acquired immune deficiency syndrome can be based upon inhibition of HIV-1 integrase.
