  Synthesis of novel 7-imino-2-thioxo-3,7-dihydro-2H-thiazolo [4,5-d] pyrimidine derivatives as adenosine A2A receptor antagonists

  摘要：

  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.

  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 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.

  A series of 3-phenyl/ethyl-2-thioxo-2,3-dihydrothiazolo[4,5-d]pyrimidin-7-yl urea and thiourea derivatives were designed and synthesized. All the compounds have been evaluated for their anti parkinsonian activity in catalepsy induced by haloperidol in mice. A majority of the compounds exhibited significant anti parkinsonian activity after intraperitoneal administration. The most active compound carries methoxy group at 2-position of the phenyl ring. Some of the potent compounds were selected for biochemical estimations of malondialdehyde, glutathione, superoxide dismutase and glutathione peroxidase from brain homogenate to highlight the neuroprotective properties associated with them. The results obtained in the present study may lead to the development of a suitable approach to the treatment of Parkinson's disease and may be the starting point for the future drug design.
