  Structure-Activity Study of Tripeptide Thrombin Inhibitors Using .alpha.-Alkyl Amino Acids and Other Conformationally Constrained Amino Acid Substitutions

  摘要：

  In our continuing effort to design novel thrombin inhibitors, a series of conformationally constrained amino acids (e.g. alpha-alkyl, N-alkyl cyclic, etc.) were utilized in a systematic structure-activity study of the P3, P2, and P1 positions of tripeptide arginal thrombin inhibitors. Early examples of this effort include: D-MePhe-Pro-Arg-H (15), Boc-D-Phg-Pro-Arg-H (18), D-1-Tiq-Pro-Arg-H (23, D-1-Tiq D-1,2,3,4-tetrahydroisoquinolin-1-ylcarbonyl), and Boc-D-Phe-Pro-Arg-H (25).(10a,20) The current work clarifies the contribution of each residue of the tripeptide arginals toward the potent and selective inhibition of thrombin relative to that of t-PA and plasmin. The alpha-methylarginal modification in the P1 residue resulted in analogs 30 (D-MePhe at P3) and 32 (D-1-Tiq at P3) which had lower potency toward thrombin while exhibiting improved selectivity. Analogs modified at the P2 site were found to be very sensitive to the conformational changes induced by variations in side chain ring size with the flexible pipecolinic acid 31 being 2 orders of magnitude less potent at thrombin inhibition than the conformationally constrained azetidine analog 20. Examination of the P3 binding region indicated that alpha-alkylphenylglycine residues resulted in a tendency to exhibit substantial improvements in selectivity over the nonalkylated residues. Combinations of optimal P3 and P2 changes led to compounds TFA-D-Phg(alpha Et)-Azt-Arg-H (16), TFA-D-Phg(alpha Me)-Azt-Arg-H (17), Ac-D-Phg(alpha Me)-Azt-Arg-H (21), TFA-D-Phg(alpha Me)-Pro-Arg-H (27), 30, and 32, which are clearly more selective for thrombin versus plasmin than the nonconformationally constrained compounds.

  The first catalytic hydrocarboxylation of enamides and imines with CO2 to generate valuable α,α‐disubstituted α‐amino acids is reported. Notably, excellent chemo‐ and regio‐selectivity are achieved, significantly different from previous reports on β‐carboxylation of enamides, homocoupling or reduction of imines. Moreover, this transition‐metal‐free procedure exhibits low loading of an inexpensive catalyst

  据报道，酰胺和亚胺与CO 2的第一次催化加氢羧化反应生成有价值的α，α-二取代的α-氨基酸。值得注意的是，实现了出色的化学和区域选择性，这与先前有关酰胺的β-羧化，亚胺的均偶联或还原的报道有显着差异。此外，这种无过渡金属的方法显​​示出廉价催化剂的低负载量，易于获得的底物，温和的反应条件，高效，易扩展性和易于产品衍生化，为有机合成，药物化学和生物化学的应用提供了巨大潜力。
