  Adenosine A2A receptor (A2AR) antagonists have emerged as complementary non-dopaminergic drugs to alleviate Parkinson’s disease (PD) symptomatology. Here, we characterize a novel non-xhantine non-furan A2AR antagonist, PBF509, as a potential pro-dopaminergic drug for PD management. First, PBF509 was shown to be a

  Adenosine inhibits the biological functions of T lymphocytes infiltrating the cancer tissue by binding to the A 2A receptor. The affinity to A 2B receptor is believed to attenuate the response of dendritic cells and other parts of innate system. Thus blocking simultaneously the effects mediated by both receptor subtypes with dual inhibitor ...

Adenosine plays a role in energy processes, neurotransmission, and endogenous regulation of inflammatory responses. Istradefylline is a selective adenosine A2a receptor (A2aR) antagonist used for the treatment

  he adenosine A 2A receptor (A 2AR) is one of the four sub-types of adenosine receptors (A 1R, A 2AR, A 2BR, A 3R). As a member of the G protein-coupled receptor (GPCR) family, the A 2A receptor couples to stimulatory G protein G s and elevates intracellular cAMP upon activation by endogenous adenosine. The A 2AR has been an attractive drug ...

  Adenosine is a significant endogenous neuromodulator in the CNS [18]. Adenosine receptors play pivotal role in mediating adenosine transduction [19,20]. Regarding bio-chemical, pharmacological, structural functions and properties, four subtypes of adeno-sine receptors have been distinguished, i.e., A1, A2A, A2B and A3 [19]. Among them, A1
