  N-Terminal Dipeptides of d(−)-Penicillamine as Sequestration Agents for Acetaldehyde

  摘要：

  Since acetaldehyde (AcH), a toxic oxidation product of ethanol, may play an etiologic role in the initiation of alcoholic liver disease, we had earlier pioneered the development of beta,beta-disubstituted-beta-mercapto-alpha-amino acids as AcH-sequestering agents. We now report the synthesis of a series of N-terminal dipeptides of D(-)-penicillamine, prepared from the synthon 3-formyl-2,2,5,5-tetramethylthiazolidine-4S-carboxylic acid (3), a cyclized N-protected derivative of D(-)-penicillamine. These dipeptides were equally or more effective than penicillamine in trapping AcH in a cell-free system. In experiments using a hepatocyte culture system, two of the dipeptides, D-penicillamylglycine (6a) and D-penicillamyl-beta-alanine (6d), at 1/20 the molar concentration of ethanol, lowered the concentration of ethanol-derived AcH by 79% and 84%, respectively, at 2 h. The presence of cyanamide tan inhibitor of aldehyde dehydrogenase) in the incubation medium resulted in a 45-fold increase in ethanol-derived AcH; nevertheless, dipeptides 8a and 6c (D-penicillamyl-alpha-aminoisobutyric acid) were able to reduce this AcH level by approximately one-third.

  一种L-青霉胺的制备方法

  摘要：

  本发明公开了一种制备L‑青霉胺的方法，如下步骤：首先采用丙酮和甲酸乙酯保护D‑青霉胺中的巯基和氨基，得到N‑甲酰异丙基‑D‑青霉胺；然后，采用醋酸或醋酸与甲苯的混合液对N‑甲酰异丙基‑D‑青霉胺进行消旋，得到N‑甲酰异丙基‑D、L‑青霉胺；N‑甲酰异丙基‑D、L‑青霉胺与盐酸反应，制得N‑甲酰异丙基‑D、L‑青霉胺盐酸盐；N‑甲酰异丙基‑D、L‑青霉胺盐酸盐在低级醇中通过有机碱游离得到游离消旋体D、L‑青霉胺；D、L‑青霉胺与拆分剂L‑酒石酸反应，得到L‑青霉胺·L‑酒石酸盐；L‑青霉胺·L‑酒石酸盐用有机碱解盐得到L‑青霉胺。本发明的制备方法所用拆分试剂价格低廉，反应条件温和，产品收率高，为工业化大批量生产L‑青霉胺提供了可行性。
