  2-Benzyl-2-methylsuccinic acid as inhibitor for carboxypeptidase A. synthesis and evaluation

  摘要：

  Recently, Asante-Appiah et al. (Asante-Appiah, E.; Seetharaman, J.; Sicheri, F.; Yang, D. S.-C.; Chan, W. W.-C. Biochemistry 1997, 36, 8710-8715) reported that 2-ethyl-2-methylsuccinic acid isa highly potent inhibitor for carboxypeptidase A (CPA), a prototypic zinc protease. The X-ray crystal structure of the complex of the enzyme formed with 2-ethyl-2-methylsuccinic acid revealed that at the active site of CPA there is present a small cavity which accommodates the methyl group of the inhibitor. These investigators postulated that incorporation of a methyl group at the alpha-position to the carboxylate of existing inhibitors of CPA would improve the inhibitory potency. We have synthesized racemic and optically active 2-benzyl-2-methylsuccinic acids and evaluated their inhibitory activities for CPA to find the K-i values to be 0.28, 0.15, and 17 mu M for racemic form, (R)-, and (S)-enantiomer, respectively. Contrary to the expectation, the effect on the binding affinity by the incorporation of the methyl group is minimal. The validity of the proposition that the small cavity may be utilized for the improvement of the inhibitory potency appears questionable. (C) 1999 Elsevier Science Ltd. All rights reserved.
