概述
用途：
它是一种新颖的，长效的，可口服的 mGlu5 受体别构拮抗剂，IC50 值为 2.2 nM，对其选择性是对其他 mGlu 受体的 1000 多倍。
Information
CTEP (RO4956371) is a novel, long-acting, orally bioavailable allosteric antagonist ofmGlu5receptor withIC50of 2.2 nM, shows >1000-fold selectivity over other mGlu receptors.
In vitro
CTEP inhibits quisqualate-induced Ca2+ mobilization with an IC50 of 11.4 nM and [3H]IP accumulation with an IC50 of 6.4 nM in HEK293 cells stably expressing human mGlu5. CTEP inhibits the constitutive activity of human mGlu5 by approximately 50% with an IC50 of 40.1 nM in HEK293 cells stably expressing human mGlu5.
In vivo
CTEP is significantly active at doses of 0.1 mg/kg and 0.3 mg/kg in treatment of anxiety in mouse. CTEP significantly increases drinking time at doses of 0.3 mg/kg and 1.0 mg/kg in the Vogel conflict drinking test in rat, whereas it has no effect at lower doses. The half-life of CTEP (oral) is 18 h, and the B/P ratio based on total drug concentrations in plasma and whole brain homogenates is 2.6 in mice. After single oral doses of 4.5 and 8.7 mg/kg CTEP formulated as microsuspension in a saline/Tween vehicle administrated to adult C57BL/6 mice is rapidly absorbed and achieves close to maximal exposure after approximately 30 min. Chronic administration in adult mice with a dose of 2 mg/kg p.o. every 48 h for 2 months reaches a minimal CTEP brain exposure of 240 ng/g. CTEP fully displaces [3H]ABP688 in mouse brain regions known to express mGlu5, and 50% displacement is achieved with doses producing an average compound concentration of 77.5 ng/g measured in whole brain homogenate. CTEP (2 mg/kg p.o. bid) achieves uninterrupted mGlu5 occupancy per 48 hours in mice. CTEP (2 mg/kg p.o.) treatment corrects elevated hippocampal long-term depression, excessive protein synthesis, and audiogenic seizures in the Fmr1 knockout mouse.
