  An enantioselective Biginelli reaction that proceeds by a dual-activation route has been developed by using a combined catalyst of a readily available trans-4-hydroxyproline-derived secondary amine and a Bronsted acid. Aromatic, heteroaromatic, and fused-ring aldehydes were found to be suitable substrates for this multicomponent reaction. The corresponding dihydropyrimidines were obtained in moderate-to-good

  通过使用容易获得的反式4-羟基脯氨酸衍生的仲胺和布朗斯台德酸的组合催化剂，已经开发了通过双活化途径进行的对映选择性比吉内利反应。发现芳族，杂芳族和稠环醛是该多组分反应的合适底物。在温和条件下，以中等至良好的收率获得了相应的二氢嘧啶，收率高达98％ee。根据实验结果和观察到的产物的绝对构型，提出了一个合理的过渡态来解释激活和不对称诱导的起源。

  Combinatorial libraries of HIV and FIV protease inhibitors are characterized by α-keto amide or hydroxyethylamine core structures flanked by on one side by substituted pyrrolidines, piperidines, or azasugars and on the other side by phenylalanine, tyrosine, or substituted tyrosines. The libraries are synthesized via a one step coupling reaction. Highly efficacious drug candidates are identified by screening the libraries for binding and inhibitory activity against both HIV and FIV protease. Drug candidates displaying clinically useful activity against both HIV and FIV protease are identified as being potentially resistive against a loss of inhibitory activity due to development of resistant strains of HIV.

  HIV和FIV蛋白酶抑制剂的组合库以α-酮酰胺或羟乙基胺核心结构为特征，一侧为取代吡咯烷、哌啶或氮代糖，另一侧为苯丙氨酸、酪氨酸或取代酪氨酸。这些库是通过一步偶联反应合成的。通过筛选这些库，识别出对HIV和FIV蛋白酶的结合和抑制活性高效的药物候选化合物。对HIV和FIV蛋白酶都显示出临床有用活性的药物候选化合物被确定为潜在对抗由于HIV耐药株的发展而导致的抑制活性丧失。

  Systematic replacement in the 3- or 4-position of the pyrrolidine ring at P1' proline was carried out. Compound 26, which has a C1 atom in the 4(S)-position was the most active among inhibitors substituted with other halogen atoms or other substituents. Furthermore, the replacement of the Z group in compound 26 with five- or six-membered fused aromatic heterocycle carbonyl groups produced more potent inhibitors. 7-Methoxybenzofuran-2-carbonyl derivative (44) was the best of these and showed K-i = 4.5 nM against HIV PR and IC(50)s 0.58 mu M and 0.06 mu M in chronic and acute infections, respectively. These results suggest that the combination of the 4(S)-Cl atom and fused bicyclic heterocycles may be effective in improving their cellular penetration. Copyright (C) 1996 Elsevier Science Ltd

  日期：——

  Some HIV-protease inhibitor derivatives having an N-carbomethoxycarbonyl-prolyl-phenylalanine benzyl ester (CPF) moiety as a binding site to gp120 were designed and synthesized. Almost all the compounds bearing CPF on the phenoxyacetyl group showed protease-inhibitory activity. Compounds 25a and 25b, which have the CPF moiety at the ortho- and meta-positions of the phenoxyacetyl group, respectively, had anti-HIV activity, although the others showed only protease-inhibitory activity. These results suggest that 25b binds to gp120 and inhibits HIV protease.
