Uses
GR 79236 is an Adenosine A1-R agonist.
Definition
ChEBI: (2R,3R,4S,5R)-2-[6-[[(1S,2S)-2-hydroxycyclopentyl]amino]-9-purinyl]-5-(hydroxymethyl)oxolane-3,4-diol is a purine nucleoside.
Biological Activity
Adenosine A 1 receptor agonist (K i = 3.1 nM). Anticonvulsive in mice following systemic administration in vivo .
in vitro
gr79236 is a highly potent and selective a1 receptor agonist which is originally developed for the treatment of type 2 diabetes mellitus, as a cardioprotective agent and also for peripheral arterial occlusive diseases. gr79236 inhibited catecholamine-induced lipolysis in adipocytes at low concentrations [1]
in vivo
gr79236 has a pronounced effect on nefa and tg levels in both acute and chronic animal models, thus establishing the potential of this approach for the treatment of t2d [1]. gr79236 also can inhibit neurogenic vasodilation in anaesthetized rats, inhibit electrical stimulation of superior saggital sinusinduced trigeminovascular nociceptive transmission and cgrp release in anaesthetized cats and inhibit trigeminal nociception in humans [2].
