  Diverse combinatorial design, synthesis and in vitro evaluation of new HEPT analogues as potential non-nucleoside HIV-1 reverse transcription inhibitors

  摘要：

  New analogues of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT) were synthesized and evaluated for their in vitro activities against HIV-1 in MT-4 cell cultures. Chemical diversity was introduced in 4 of the six positions of the core and the influence of each substituent was studied. This library was built on the basis of a rational diversity analysis with the objective of maximizing diversity and thus, the activity range with a minimum number of synthesized compounds. Among them, 2{1,2,3,1} and 2 {1,2,3,4} exhibited the most potent anti-HIV-1 activities (EC50 = 0.015 mu g/mL; 0.046 mu M, SI > 1667) and (EC50 = 0.025 mu g/mL; 0.086 mu M, SI > 1000), respectively, which were about 71-fold and 38-fold more active than the reference compound HEPT (EC50 = 1.01 mu g/ml; 3.27 mu M, SI > 25).

• Nonnucleoside HIV-1 Reverse-Transcriptase Inhibitors, Part 5. Synthesis and Anti-HIV-1 Activity of Novel 6-Naphthylthio HEPT Analogues

  As part of a series of studies to discover new HIV reverse-transcriptase inhibitors, various novel 6α- and 6β-naphthylthio 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio) thymine (HEPT) derivatives were synthesized, and in vitro anti-HIV-1 activity was evaluated. The results revealed that most of 6α-naphthylthio HEPT derivatives (7a—w) showed good activity [for 7e, IC50 value of 0.048 μM and selectivity index (SI) value of 735; for 7h, IC50 value of 0.057 μM and SI value of 579; for 7k, IC50 value of 0.063 μM and SI value of 565], 6β-naphthylthio HEPT derivatives (8a—f) showed low activity, but the introduction of α nitro group to the C-1 position of the 6β-naphthyl ring in the 6β-naphthylthio series (11a—c) resulted in a dramatic increase in anti-HIV-1 activity.

  作为发现新的 HIV 逆转录酶抑制剂的一系列研究的一部分，合成了各种新型 6α- 和 6β- 萘硫基 1-[(2-羟乙氧基)甲基]-6-（苯硫基）胸腺嘧啶（HEPT）衍生物，并对其体外抗 HIV-1 活性进行了评估。结果表明，大多数 6α-naphthylthio HEPT 衍生物（7a-w）都表现出良好的活性[7e 的 IC50 值为 0.048 μM，选择性指数（SI）值为 735；7h 的 IC50 值为 0.057 μM，选择性指数（SI）值为 579；7k 的 IC50 值为 0.063 μM，选择性指数（SI）值为 0.063 μM，SI 值为 565]，6β-萘硫基 HEPT 衍生物（8a-f）的活性较低，但在 6β-萘硫基系列（11a-c）的 6β-萘环的 C-1 位上引入 α 硝基后，抗 HIV-1 活性显著提高。

  The one-pot reduction-sulfenylation of 5-alkyl-6-chlorouracils (1) with diaryl disulfides (2) and sodium borohydride in methanol was carried out to afford 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine HEPT analogues in good to excellent yields.
