生物活性 | MRK-016 is a selective, orally bioavailable inverse agonist ofGABAAα5 receptor, with anEC50of 3 nM for GABAAα5, andKis of 0.83, 0.85, 0.77 and 1.4 nM for human GABAA α1β3γ2, GABAA α2β3γ2, GABAA α3β3γ2, and GABAA α5β3γ2, respectively; MRK-016 also readily penetrates the CNS. | ||||||||||||||||

体外研究 (In Vitro) | MRK-016 is a selective, orally bioavailable inverse agonist of GABAAα5 receptor, with an EC50of 3 nM for GABAAα5, and Kis of 0.83, 0.85, 0.77 and 1.4 nM for human GABAA α1β3γ2, GABAA α2β3γ2, GABAA α3β3γ2, and GABAA α5β3γ2, respectively[1][2]. MRK-016 is a full inverse agonist at the α5-subtype, shows very weak affinity at the GABAAα4β3γ2-subtype (Ki395 ± 173 nM) and is essentially inactive at the GABAAα6β3γ2 receptor (Ki>4000 nM)[1]. MRK-016 shows a weak effect on GABAA α4β3γ2 with a Kiof 400 nM. MRK-016 (100 nM) alao increases long-term potentiation in mouse hippocampal slices[2]. | ||||||||||||||||
体内研究 (In Vivo) | MRK-016 does not enhance pentylenetetrazole-induced convulsions at 10 mg/kg via ip, or cause seizures at 30 mg/kg, via po for 20 days in mice. MRK-016 shows no obvious anxiogenic-like effects in rats at doses that occupy >95% of benzodiazepine (BZ) binding sites. MRK-016 (0.3, 1, and 3 mg/kg, p.o.) dose-dependently improves performance of rats hippocampal-dependent memory task[1]. MRK-016 (0.3-30 mg/kg, p.o.) causes good receptor occupancy in rats. MRK-016 (0.3, 1, or 3 mg/kg p.o.) shows cognition-enhancing activity in the delayed matching-to-position version of the Morris water maze. MRK-016 (1, 3, or 10 mg/kg i.p.) does not produce kindling in mice[2]. MRK-016 (3 mg/kg, i.p.) protects against LPS-induced learning/memory decrements in mice[3]. | ||||||||||||||||
