  Investigation of the Active Site of Aminopeptidase A Using a Series of New Thiol-Containing Inhibitors

  摘要：

  Aminopeptidase A (APA) and aminopeptidase N (APN) are two metallopeptidases which have been suggested to be involved in the enzymatic cascade of the renin-angiotensin system. APA liberates angotensin III from angiotensin II by releasing the N-terminal aspartate, and APN participates in the inactivation of angiotensin III. As the role of angiotensin III in the regulation of blood pressure in the central nervous system and at the periphery is controversial, it was of interest to develop selective and efficient inhibitors of APA. Starting from Glu-thiol,(1) which was the first efficient APA inhibitor described, but however is equipotent on APA (K-i = 0.14 mu M) and APN (K-i = 0.12 mu M), beta-amino thiols bearing various carboxyalkyl chains have been synthesized and their inhibitory potencies measured on both purified enzymes. Compounds containing a carboxylated aromatic ring inhibited APA and APN with K-i values in the micromolar range but were slightly more active on APA. Conversely, inhibitors containing a cyclohexyl ring were more efficient on APN. Various modifications of the structure of Glu-thiol decreased inhibitory activity on both enzymes but increased the selectivity for APA, and compound 9d ((S)-4-amino-6-mercaptohexanoic acid) was 23 times more potent on APA (K-i = 2.0 mu M) than on APN (K-i = 45 mu M).

• Synthesis of Arylglycine and Mandelic Acid Derivatives through Carboxylations of α-Amido and α-Acetoxy Stannanes with Carbon Dioxide

  DOI：10.1021/jo202597p

  日期：2012.3.2

  Incorporation reactions of carbon dioxide (CO2) with N-Boc-alpha\-amido and a-acetoxy stannanes were developed using CsF as a mild tin activator. Monoprotected alpha-amido stannanes could be used, and the corresponding arylglycine derivatives were obtained in moderate-to-high yields under 1 MPa (10 atm) of CO2 pressure. alpha-Acetoxy stannanes also underwent carboxylation to afford mandelic acid derivatives in excellent yields under ambient CO2 pressure. Both transformations enabled the synthesis of alpha-tertiary and alpha-quaternary carboxylic acid derivatives. In addition, the chirality of (S)-N-tert-butylsulfonyl-alpha-amido stannanes was transferred with up to 90% inversion of configuration at 100 degrees C.
