产品描述:
AS-19 is an agonist of the serotonin (5-HT) receptor subtype 5-HT7 (Ki = 0.6 nM).{48277} It is selective for 5-HT7 over 5-HT1A, 5-HT1B, 5-HT1D, and 5-HT5A receptors (Kis = 89.7, 490, 6.6 and 98.5 nM, respectively), as well as sigma-1 and imidazoline I2 receptors (Kis = 657 and 282 nM, respectively). AS-19 increases conditioned responses and reverses amnesia induced by the muscarinic acetylcholine receptor antagonist scopolamine in rats in an autoshaping learning task when administered post-training at a dose of 5 mg/kg.{48278} It increases the paw withdrawal threshold in a mechanical pressure test in rats with chronic constriction injury when 0.3 µl of a 1.5 nM solution is injected into the ventrolateral periaqueductal gray area (vlPAG), an effect that can be blocked by the 5-HT7 receptor antagonist SB-269970 (Item No. 17081).{48279}
