    Product Description

    PHA-543613 is an agonist of α7 nicotinic acetylcholine receptors (nAChRs).1,2 It is selective for α7 nAChRs over α4β2-, α4β4-, α3β2-, or α3β4 subunit-containing nAChRs and the serotonin (5-HT) receptor subtype 5-HT3 (EC50s = 0.03, >100, >50, >100, >100, and 11 µM, respectively, in calcium mobilization assays).2 PHA-543613 prevents decreases in the number of retinal ganglion cells in a rat model of glaucoma when applied topically.3 It improves sensorimotor deficits and reduces brain edema in a mouse model of intracerebral hemorrhage, effects that can be reversed by methyllycaconitine (Item No. 21398) or wortmannin (Item No. 10010591).4 PHA-543613 (1 mg/kg) increases the time spent with the novel object in the novel object recognition test and reverses amphetamine-induced auditory gating deficits in rats.1 Intracerebroventricular administration of PHA-543613 (0.1 mg/animal) reduces food intake and body weight in rats.5
