Design and synthesis of (4E)-4-(4-substitutedbenzylideneamino)-3-substituted-2,3-dihydro-2-thioxothiazole-5-carbonitrile as novel A2A receptor antagonists
Novel 2-thioxothiazole derivatives (6-19) as potential adenosine A(2A) receptor (A(2A)R) antagonists were synthesized. The strong interaction of the compounds (6-19) with A(2A)R in docking study was confirmed by high binding affinity with human A(2A)R expressed in HEK293T cells using radioligand-binding assay. The compound 19 demonstrated very high selectivity for A(2A)R as compared to standard A(2A)R antagonist SCH58261. Decrease in A(2A)R-coupled release of endogenous cAMP in treated HEK293T cells demonstrated in vitro A(2A)R antagonist potential of the compound 19. Attenuation in haloperidol-induced impairment (catalepsy) in Swiss albino male mice pre-treated with compound 19 is evocative to explore its prospective in therapy of PD. (c) 2013 Elsevier Ltd.
