  Synthesis of 2-piperidinecarboxylic acid derivatives as potential anticonvulsants

  摘要：

  A variety of 2-piperidinecarboxamides were synthesized and evaluated for anticonvulsant activity using the MES and sc PTZ tests in mice and rats. Neurotoxicity was determined by the rotorod test. Several N-(benzyl)-2-piperidinecarboxamides exhibited potent MES activity in mice [2-CF3 14, ED50 = 29 mg/kg; 3-F 16, ED50 = 31 mg/kg; and 3-CF3 17, ED50 = 24 mg/kg]. The most active compounds in the MES test in mice were the 2,6-dimethylanilides [(R,S)-34, ED50 = 5.8 mg/kg; (R)-35, ED50 = 5.7 mg/kg; and (S)-36, ED50 = 14.8 mg/kg]. The enantiomer (S)-36 was about two-fold less potent in the MES test than (R)-35 and also was less neurotoxic. Acylation of the piperidine ring nitrogen of 12 and 34 led to a decrease in the MES activity. In the N-(alpha-methylbenzyl)-2-piperidine-carboxamides, the stereochemistry at either the 2-position of the piperidine ring or at the alpha-position of the N-(alpha-methylbenzyl) group does not significantly affect MES activity.

  The design, synthesis, and crystallographic analysis of protein-inhibitor complexes is described for a novel series of nonpeptidic HIV protease (HIV Pr)inhibitors. Beginning with a cocrystal structure of a Phe-Pro peptidomimetic bound to the HIV Pr, design was initiated that resulted in the substituted 2-butanol compound 8 as the lead compound (Ki = 24.5 microM, racemic mixture). Modifications on the

  蛋白质抑制剂复合物的设计，合成和晶体学分析描述了一系列新型非肽类HIV蛋白酶（HIV Pr）抑制剂。从与HIV Pr结合的Phe-Pro拟肽的共晶体结构开始，开始设计，最终得到取代的2-丁醇化合物8作为前导化合物（Ki = 24.5 microM，外消旋混合物）。然后根据其与HIV Pr的共晶结构和抑制数据对初始化合物进行修饰，从而产生具有增强的针对该酶的效力的化合物（化合物18，Ki = 0.48 microM）。发现这些抑制剂基本上根据原始设计假设所预测的与酶结合。单个对映异构体的立体特异性合成证实了对S醇立体化学的结合偏好的预测。在感染了HIV-1的CEM-SS细胞系中，对几种更有效的HIV Pr抑制剂表现出了适度的抗病毒活性。

  versatile N-carboxyanhydrides (NCAs) directly from amino acids and CO2 using n-propylphosphonic anhydride. Most of the NCAs were isolated with >95% purity after simple workup, avoiding the need for tedious purification procedures typically required using conventional methods. Because the reagents and conditions employed are mild, tandem reactions with moisture-sensitive NCAs were carried out to transform

  我们报告了使用正丙基膦酸酐直接从氨基酸和 CO 2制备综合通用的N-羧基酸酐 (NCA) 。大多数 NCA 在简单的后处理后以 > 95% 的纯度被分离出来，避免了使用传统方法通常需要的繁琐纯化程序的需要。由于所使用的试剂和条件温和，因此与对水分敏感的 NCA 进行串联反应，将它们在一锅中转化为药用生物碱色胺菊酯和 Phaitanthrin A。定性分析表明，我们的 NCA 合成方法比直接或间接使用剧毒气体光气的传统方法更环保。

  La présente invention a pour objet un nouveau procédé de synthèse de composés NCAs. Elle concerne également une nouvelle utilisation d'un agent de couplage peptidique. Le procédé selon l'invention permet d'obtenir les composés NCAs à partir d'acides-α-aminés, dans des conditions réactionnelles douces et non-racémisantes, et en absence de réactifs contraignants d'utilisation, tel que le phosgène, pouvant conduire à la formation de sous-produits non-désirables.
