ML381 (VU0488130) is a highly selective, central nervous system-penetrant mAChR M5 orthogonal antagonist with nanomolar potency that exhibits instability in rat plasma, limiting its in vivo utility while establishing its primary value as a molecular probe for in vitro pharmacological characterization and electrophysiological studies of M5 receptor function.

| Description | ML381 (VU0488130) is a highly selective, central nervous system-penetrant mAChR M5 orthogonal antagonist with nanomolar potency that exhibits instability in rat plasma, limiting its in vivo utility while establishing its primary value as a molecular probe for in vitro pharmacological characterization and electrophysiological studies of M5 receptor function. |
| In vitro | In functional calcium mobilization assays utilizing CHO cells stably expressing human mAChR subtypes, ML381 was evaluated for its inhibitory profile. The compound demonstrated robust antagonism against the M5 receptor with an IC50 of 190 nM[2]. |
