Novel synthetic approach to N-aryl-4-(3-pyridyl)thiazol-2-amine and analogues using HMCM-41 as catalyst, and their biological evaluation as human platelet aggregation inhibitors
摘要:
A novel synthetic approach to N-aryl-4-(3-pyridyl)thiazol-2-amine and analogues using HMCM-41, a mesoporous aluminosilicate catalyst and their in vitro ADP-induced platelet aggregation inhibitory activity on human blood platelets is described. Among the test compounds N-(2'flourophenyl)-4-(3-pyridyl)thiazol-2-amine (9e) was found to be the most potent, IC50 = 4.84 x 10(-7) M. (c) 2007 Published by Elsevier Masson SAS.

An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.

N,N,N″-Trisubstituted guanidines (most of them N″-aryl-N-azacycloalkanecarboximidamides) are prepared in generally good yields by S-methylation of monosubstituted thioureas with methyl iodide in methanol or acetone and reaction of the resultant methyl carbamimidothioate hydroiodides with secondary amines in boiling tert-butyl alcohol or acetonitrile.

To develop agents for the treatment of infections caused by Mycobacterium tuberculosis, a novel phenotypic screen was undertaken that identified a series of 2-N-aryl thiazole-based inhibitors of intracellular Mycobacterium tuberculosis. Analogs were optimized to improve potency against an attenuated BSL2 H37Ra laboratory strain cultivated in human macrophage cells in vitro. The insertion of a carboxylic acid functionality resulted in compounds that retained potency and greatly improved microsomal stability. However, the strong potency trends we observed in the attenuated H37Ra strain were inconsistent with the potency observed for virulent strains in vitro and in vivo. (C) 2017 Elsevier Ltd.
