  名称：

  2-Alkynyl-8-aryladenines possessing an amide moiety: their synthesis and structure–activity relationships of effects on hepatic glucose production induced via agonism of the A2B adenosine receptor

  摘要：

  A series of 2-alkynyl-8-aryladenine derivatives bearing an amide moiety at the 9-position of adenine was synthesized. These analogues were evaluated for inhibitory activity on N-ethylcarboxamidoadenosine (NECA)-induced glucose production in primary cultured rat hepatocytes. The in-primary benzamide derivative 15f was the most potent compound (IC50 = 0.017 PM), being 15-fold more active than the corresponding 9-methyl derivative (1). Compound 15f showed 72- and 5.2-fold selectivity for human A(2B) receptor versus human A(1) and A(2A) receptors, respectively. Structure-activity relationship (SAR) studies of the synthesized compounds indicated that a three-carbon linker, fixed in the form of a benzene ring, between the adenine core and the amide moiety is important for both A(2B) antagonistic activity and selectivity, The IC50 values in rat hepatocyte glucose assay correlated well with the IC50 values in cAMP assay using Chinese hamster ovary cells stably transfected with human A(2B) receptors (r(2) = 0.94). The A(1) and A(2A) affinities showed no correlation with the potency to inhibit NECA-induced glucose production. These results strongly support our previous conclusion that adenosine agonist-induced hepatic glucose production in rat hepatocytes is mediated through the A(2B) receptor.
