Use | ML380 is a potent, subtype-selective, and brain-penetrant positive allosteric modulator (PAM) of M5 mAChR, with EC50s of 190 and 610 nM for human and rat M5, respectively. ML380 exhibits moderate selectivity versus the M1 and M3 mAChR subtypes. ML380 could increase the affinity of ACh for the M5 mAChR. |
Target | IC50: 190 nM (hM5), 610 nM (rM5) |
In vitro study | ML380 (0.01 nM-100 μM) robustly stimulates inositol phosphate (IP) accumulation and Ca 2+ mobilization in CHO-hM 5 cells, with pEC 50 s of 5.33 and 5.71, respectively. ML380 (0.01-30 μM) increases the ACh-stimulated IP accumulation and Ca 2+ mobilization in CHO-hM 5 cells. |
In vivo study | ML380 (1 mg/kg; i.v.) displays high clearance (66 mL/min/kg), a moderate volume of distribution (1.6 L/kg), and a short half-life (t 1/2 , 22 min) in rats. |

biological activity | ML380 is an effective, subtype-selective and blood-brain barrier permeable M5 mAChR positive allosteric regulator (PAM). The EC50 values for human and rat M5 are 190 and 610 nM respectively. ML380 is moderately selective for M1 and M3 mAChR subtypes. ML380 can increase Ach's affinity for M5 mAChR. |
