General description

CGS 21680 is a potent adenosine A2A receptors agonist (Ki = 27 nM) and xanthin derivative. CGS 21680 HCl exhibits reduced affinity for A2B receptors (Ki = 67 nM), but offers greater selectivity over A1R (Ki = 290 nM) and A3R (88.8 µM). Exerts an anti-inflammatory effect during chronic inflammation and ameliorates the tissue damage associated with collagen-induced arthritis. Been, shown to reduce CCR7 Protein Expression in THP1 macrophages. Shown to delay the progressive deterioration of motor performance and prevent a reduction in brain weight in murine model of Huntington′s disease.

Pannexins are large-pore ion channels expressed throughout the mammalian brain that participate in various neuropathologies; however, their physiological roles remain obscure. Here, we report that pannexin1 channels (Panx1) can be synaptically activated under physiological recording conditions in rodent acute hippocampal
