  用于对抗耐药性的新型 HIV-1 蛋白酶抑制剂的设计、合成以及生物学和结构评估

  摘要：

  一系列新的 HIV-1 蛋白酶抑制剂 (PI) 是使用一种通用策略设计的，该策略将基于计算结构的设计与底物包络约束相结合。PI 将具有无环和环状杂原子官能团的各种醇衍生的 P2 氨基甲酸酯结合到 ( R )-羟乙胺等排体中。大多数新的 PI 显示出对野生型 HIV-1 蛋白酶和三种多重耐药 (MDR) 变体的有效结合亲和力。特别是，含有 2,2-二氯乙酰胺、吡咯烷酮、咪唑烷酮和 恶唑烷酮部分的抑制剂在 P2 处对K i最有效皮摩尔范围内的值。几种新的 PI 对来自 HIV-1 进化枝 A、B 和 C 以及两种 MDR 变体的患者来源的野生型病毒表现出纳摩尔级的抗病毒效力。四种有效抑制剂的晶体结构分析表明，新 P2 部分的羰基促进了与蛋白酶不变的 Asp29 残基的广泛氢键相互作用。这些构效关系的发现可用于设计具有增强的酶抑制和抗病毒效力的新 PI。

  A series of new HIV-1 protease inhibitors (PIs) were designed using a general strategy that combines computational structure-based design with substrate-envelope constraints. The PIs incorporate various alcohol-derived P2 carbamates with acyclic and cyclic heteroatomic functionalities into the (R)-hydroxyethylamine isostere. Most of the new PIs show potent binding affinities against wild-type HIV-1

  The acquisition of drug-resistant mutations by infectious pathogens remains a pressing health concern, and the development of strategies to combat this threat is a priority. Here we have applied a general strategy, inverse design using the substrate envelope, to develop inhibitors of HIV-1 protease. Structure-based computation was used to design inhibitors predicted to stay within a consensus substrate volume in the binding site. Two rounds of design, synthesis, experimental testing, and structural analysis were carried out, resulting in a total of 51 compounds. Improvements in design methodology led to a roughly 1000-fold affinity enhancement to a wild-type protease for the best binders, from a K(i) of 30-50 nM in round one to below 100 pM in round two. Crystal structures of a subset of complexes revealed a binding mode similar to each design that respected the substrate envelope in nearly all cases. All four best binders from round one exhibited broad specificity against a clinically relevant panel of drug-resistant HIV-1 protease variants, losing no more than 6-13-fold affinity relative to wild type. Testing a subset of second-round compounds against the panel of resistant variants revealed three classes of inhibitors: robust binders (maximum affinity loss of 14-16-fold), moderate binders (35-80-fold), and susceptible binders (greater than 100-fold). Although for especially high-affinity inhibitors additional factors may also be important, overall, these results suggest that designing inhibitors using the substrate envelope may be a useful strategy in the development of therapeutics with low susceptibility to resistance.

  We explore the applicability of an additive treatment of substituent effects to the analysis and design of HIV protease inhibitors. Affinity data for a set of inhibitors with a common chemical framework were analyzed to provide estimates of the free energy contribution of each chemical substituent. These estimates were then used to design new inhibitors whose high affinities were confirmed by synthesis and experimental testing. Derivations of additive models by least-squares and ridge-regression methods were found to yield statistically similar results. The additivity approach was also compared with standard molecular descriptor-based QSAR; the latter was not found to provide superior predictions. Crystallographic studies of HIV protease-inhibitor complexes help explain the perhaps surprisingly high degree of substituent additivity in this system, and allow some of the additivity coefficients to be rationalized on a structural basis.
• Substrate Envelope-Designed Potent HIV-1 Protease Inhibitors to Avoid Drug Resistance

  The rapid evolution of HIV under selective drug pressure has led to multidrug resistant (MDR) strains that evade standard therapies. We designed highly potent HIV-1 protease inhibitors (Pis) using the substrate envelope model, which confines inhibitors within the consensus volume of natural substrates, providing inhibitors less susceptible to resistance because a mutation affecting such inhibitors will simultaneously affect viral substrate processing. The designed Pis share a common chemical scaffold but utilize various moieties that optimally fill the substrate envelope, as confirmed by crystal structures. The designed Pis retain robust binding to MDR protease variants and display exceptional antiviral potencies against different clades of HIV as well as a panel of 12 drug-resistant viral strains. The substrate envelope model proves to be a powerful strategy to develop potent and robust inhibitors that avoid drug resistance.
