High-affinity thrombin receptor (PAR-1) ligands: a new generation of indole-based peptide mimetic antagonists with a basic amine at the C-terminus
摘要:
A new generation of indole-based peptide mimetics, bearing a basic amine at the C-terminus, was developed by the agency of two complementary, multistep, trityl resin-based approaches. Thus, we obtained several high-affinity thrombin receptor (PAR-1) ligands, such as 32 and 34. Compounds 32 and 34 were found to bind to PAR-1 with excellent affinity IC50 = 25 and 35 nM, respectively) and to effectively block platelet aggregation induced by SFLLRN-NH2 (TRAP-6) and alpha-thrombin.

A process for the production of (1,3-disubstituted indolyl) urea derivatives represented by the general formula (1), characterized by reacting a 1-substituted-aminoindole derivative with a phenyl halocarbonate to form a carbamate derivative, subjecting the carbamate derivative to Mannich reaction with a secondary amine and formaldehyde to form a 3-aminomethylindole derivative represented by the general formula (6), and then reacting the derivative (6) with a peptide derivative; indole derivatives represented by the general formula (6) which are intermediates for the above process; and a process for the production of the indole derivatives.

A novel, 10-step, solid-phase method, based on a secondary amide linker, was developed to construct a diverse library of indole-based SFLLR peptide mimetics as thrombin receptor (protease-activated receptor 1, PAR-I) antagonists. The key steps include stepwise reductive alkylation, urea formation, and Mannich reaction. Screening of the library led to a quick development of the SAR and the significant improvement of PAR-1 activity. (C) 2001 Elsevier Science Ltd. All rights reserved.
