AMG2850
Based on 1 publication(s) in Google Scholar
AMG2850 is an orally active, blood-brain barrier-permeable selective TRPM8 competitive antagonist. AMG2850 abolishes the counterirritant effect of TRPM8 agonists, blocks TRPM8 activation induced by cold, (-)-Menthol (HY-75161) and Icilin (HY-11062), and exhibits selectivity over TRPA1, TRPV1, TRPV3 and TRPV4. AMG2850 is applicable for pain-related research.

In Vitro
AMG2850 is a potent, selective inhibitor of rat TRPM8 in CHO cells, with greater potency against cold-induced activation (IC50 7.3 nM) than Menthol ((-)-Menthol) (HY-75161)-induced activation (IC50 156 nM), and no activity at other tested TRP channels[2].
AMG2850 (2.5 min) potently and selectively inhibits rat TRPM8 in CHO cells, with IC50 values of 41 nM against cold activation and 204 nM against Icilin (HY-11062) activation, and shows minimal activity against other TRP channels[3].
AMG2850 (2 min pre-incubation; 2 min agonist/45Ca2+ incubation) inhibits agonist-induced calcium uptake in rat TRPM8-expressing CHO cells[3].

In Vivo
AMG2850 (30 mg/kg; i.p.; single dose; 10 min prior to smoke exposure) completely blocks the TRPM8-mediated counterirritant effect of L-menthol on cigarette smoke-induced respiratory irritation in female C57Bl/6J mice[1].
AMG2850 (100 mg/kg; p.o.; single dose) causes a maximum body temperature decrease of 0.98°C in male Sprague Dawley rats[2].
AMG2850 (100 mg/kg; p.o.; single dose) causes a maximum body temperature decrease of 0.73°C in male C57BL/6 mice[2].
AMG2850 (1-10 mg/kg; p.o.; single dose) dose-dependently and fully inhibits Icilin-induced wet-dog shakes in rats, with an ED50 of 1.8 mg/kg and an unbound in vivo IC90 of 99 nM[3].
AMG2850 (100 mg/kg; p.o.; single dose) does not reverse complete Freund's adjuvant-induced mechanical hypersensitivity in rats[3].

AMG2850 (10-100 mg/kg; p.o.; single dose) at doses up to 100 mg/kg p.o. does not affect open field locomotor activity in rats[3].
AMG2850 (30 mg/kg; i.g.; single dose) attenuates cold-defense mechanisms in rats, resulting in a 1.8°C nadir reduction in deep body temperature during severe cold exposure[4].
AMG2850 (0.3-10 mg/kg; p.o.; single dose) at 10 mg/kg p.o. fully blocks cold-induced increases in mean blood pressure in rats[3].
