Three-component condensation of 2,4-diaminothiazoles with aldehydes and Meldrum's acid: synthesis of 7-aryl(alkyl)-substituted 6,7-dihydro-4H-thiazolo[4,5-b]pyridin-5-ones
摘要:
The new method of the synthesis of 6,7-dihydro-4H-thiazolo[4,5-b]pyridin-5-ones, based on decarboxylation of corresponding 2,4-diamino-5-thiazolecarboxylic acids has been elaborated; unstable derivatives of 2,4-diaminothiazole, generated in situ as a result of decarboxylation, react with aldehydes and Meldrum's acid forming target compounds.
2,4-Diaminothiazole derivatives which inhibit GSK-3 (glycogen synthase kinase-3) and which are useful for the treatment and/or prevention disorders and diseases wherein an inhibition of GSK-3 is beneficial, especially especially Alzheimer's disease, bipolar disorder, IGT (impaired glucose tolerance), Type 1 diabetes, Type 2 diabetes and obesity.

2,7-Diamino-thiazolo[4,5-d]pyrimidine analogues were synthesized as novel epidermal growth factor receptor ( EGFR) tyrosine kinase inhibitors. Representative compounds showed potent and selective EGFR inhibitory activities and inhibited in vitro cellular proliferation in EGFR-overexpressing human tumor cells. The synthesis and preliminary biological, physical, and pharmacokinetic evaluation of these thiazolopyrimidine compounds are reported. (C) 2009 Elsevier Ltd. All rights reserved.
