  Novel 8-(furan-2-yl)-3-substituted thiazolo [5,4-e][1,2,4] triazolo[1,5-c] pyrimidine-2(3H)-thione derivatives as potential adenosine A2A receptor antagonists

  摘要：

  Novel thiazolotriazolopyrimidine derivatives (23-33) designed as potential adenosine A(2A) receptor (A(2A)R) antagonists were synthesized. Molecular docking studies revealed that all compounds (23-33) exhibited strong interaction with A(2A)R. The strong interaction of the compounds (23-33) with A(2A)R in silico was confirmed by their high binding affinity with human A(2A)R stably expressed in HEK293 cells using radioligand-binding assay. The compounds 24-26 demonstrated substantial binding affinity and selectivity for A(2A)R as compared to SCH58261, a standard A(2A)R antagonist. Decrease in A(2A)R-coupled release of endogenous cAMP in treated HEK293 cells demonstrated in vitro A(2A)R antagonist potential of the compounds 24-26. Attenuation in haloperidol-induced motor impairments (catalepsy and akinesia) in Swiss albino male mice pre-treated with compounds 24-26 further supports their role in the alleviation of PD symptoms.

  Novel bicyclic thiazolopyrimidine compounds (15-26) were synthesized to develop adenosine A(2A) receptor (A(2A)R) antagonist for the treatment of Parkinson's disease (PD). The binding affinity of the compounds (15-26) with A(2A)R was evaluated using radioligand binding assay on isolated membranes from stably transfected HEK293 cells. Selectivity of the compounds towards A(2A)R was assessed by comparing their binding affinities with A(1) receptors (A(1)R). cAMP concentrations were measured from HEK293 cells treated with compounds (15-26) as compared to NECA (A(2A)R agonist). The compound (16) possessed strongest A(2A)R binding affinity (K-i value = 0.0038 nM) and selectivity (737-fold) versus A(1)R. Decrease in A(2A)R-coupled release of endogenous cAMP from HEK293 cells treated with compounds (15-26) is evocative of their potential as A(2A)R antagonist. (C) 2009 Elsevier Ltd. All rights reserved.
