ML314
Based on 1 Customer Validation
ML314 is a potent, BBB-penetrant and β-arrestin biased molecule agonist of NTR1 (EC50 = 1.9 μM). ML314 shows good selectivity against NTR2 and GPR35, but does not stimulate Ca2+ mobilization. ML314 can attenuate amphetamine-like hyperlocomotion in dopamine transporter knockout mice. ML314 attenuates methamphetamine-associated hyperlocomotion and potentiates the psychostimulant inhibitory effects of a ghrelin antagonist in wild type mouse model. ML314 also acts as an allosteric enhancer of endogenous neurotensin. ML314 antagonizes G protein signaling. ML314 can be studied in research for methamphetamine abuse conditions.
