Application

CGS-15943 has been used as a non-selective adenosine receptor antagonist to study its effects on the proliferation of pancreatic ductal adenocarcinoma (PDAC) cells and hepatocellular carcinoma (HCC). It has also been used as a non-selective adenosine receptor antagonist to investigate the mechanism underlying adenosine inhibition on cholangiocarcinoma (CCA) cells.

Biochem/physiol Actions

CGS-15943 is a potent and non-selective adenosine receptor antagonist. It exhibits anti-carcinogenic and anti-apoptotic activity.

CGS 15943A, a triazoloquinazoline, is a potent and selective adenosine receptor antagonist as assessed by its effects on radioligand binding and adenosine-stimulated adenylate cyclase activity in guinea pig synaptoneurosomes. At the adenosine A-1 receptor labeled with [3H]cyclohexyladenosine, CGS 15943A had

The purpose of this study was to investigate the receptor subtypes that mediate the dilation of rat intracerebral arterioles elicited by adenosine. Penetrating arterioles were isolated from the rat brain, cannulated with the use of a micropipette system, and luminally

A three-dimensional model of the human A(2A) adenosine receptor (AR) and its docked ligands was built by homology to rhodopsin and validated with site-directed mutagenesis and the synthesis of chemically complementary agonists. Different binding modes of A(2A)AR antagonists and agonists

Caffeine and the adenosine A(1) and A(2A) receptor antagonist CGS15943 produce many behavioral effects that are similar to those produced by classic stimulant drugs (e.g. cocaine and amphetamines). The current study evaluated whether CGS15943 would maintain self-administration and reinstate extinguished

Adenosine is a potent vasodilator of vascular smooth muscle. Endothelium-derived nitric oxide (NO) elicits vasodilation. We have previously reported that adenosine stimulates the production of NO from porcine carotid arterial endothelial cells (PCAEC) via a receptor-mediated mechanism. This study was
