MRK-016

产品介绍 MRK-016 是一种选择性的,可口服的,可透过血脑屏障的 GABAA α5 receptor 拮抗剂,对 GABAA α5 的 EC50 值为 3 nM,对人 GABAA α1β3γ2,GABAA α2β3γ2,GABAA α3β3γ2 和 GABAA α5β3γ2 的 Ki 值分别为 0.83,0.85,0.77 和 1.4 nM。
生物活性

MRK-016 is a selective, orally bioavailable inverse agonist of GABAA α5 receptor, with an EC50 of 3 nM for GABAA α5, 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; MRK-016 also readily penetrates the CNS.

体外研究

MRK-016 is a selective, orally bioavailable inverse agonist of GABAA α5 receptor, with an EC50 of 3 nM for GABAA α5, 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. MRK-016 is a full inverse agonist at the α5-subtype, shows very weak affinity at the GABAA α4β3γ2-subtype (Ki 395 ± 173 nM) and is essentially inactive at the GABAA α6β3γ2 receptor (Ki > 4000 nM). MRK-016 shows a weak effect on GABAA α4β3γ2 with a Ki of 400 nM. MRK-016 (100 nM) alao increases long-term potentiation in mouse hippocampal slices.

体内研究

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. 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. MRK-016 (3 mg/kg, i.p.) protects against LPS-induced learning/memory decrements in mice.
