| Hazard Information | Back Directory | [Description]
ML375 is a potent, selective and CNS penetrant M5 negative allosteric modulator (NAM). | [Uses]
ML375 (VU0483253) is a potent, highly selective, brain-penetrant and orally active M5 mAChR negative allosteric modulator (NAM) with IC50s of 300 nM and 790 nM for human and rat M5, respectively. ML375 is inactive at human and rat M1-M4[1]. | [in vivo]
ML375 (10-30 mg/kg; i.p.; once) attenuates both the reinforcing effects and the relative strength of cocaine[2].
ML375 exhibits low clearance (CLp, 2.5 mL/min/kg) and a long elimination half-life (T1/2, 80 hr) in rodents (male, Sprague-Dawley rat, 1 mg/kg IV,) and nonhuman primates (male, cynomolgus monkey, 1 mg/kg, CLp, 3.0 mL/min/kg, T1/2, 10 hr)[1].
ML375 also demonstrates high oral bioavailability (%F, 80) following administration of a suspension-dose to male SD rats with a maximal plasma concentration (Cmax) of 1.4 μM and a corresponding time to reach Cmax (Tmax) of 7 hours[1]. | Animal Model: | Male Sprague-Dawley rats (70 days old; 260-300 g) injected with cocaine[2] | | Dosage: | 10 mg/kg, 30 mg/kg | | Administration: | i.p.; once | | Result: | Produced dose-related reductions in cocaine self-administration. |
