ML-314

ML-314 is a neurotensin-1 receptor (NTS1) agonist. It is selective for NTS1 over NTS2 in a cell-based assay of receptor/beta-arrestin complex formation (EC50s = 2 and >80 µM, respectively) but is inactive in an NTS1 calcium flux assay (EC50 = >80 µM) indicating that, in contrast to other NTS1 agonists, it does not signal through the traditional Gq-coupled pathway. ML-314 is also a positive allosteric modulator of NTS1 that increases binding of radiolabeled neurotensin (Cay-24717) to NTS1 in a concentration-dependent manner. It reduces locomotion in dopamine transporter knockout mice and methamphetamine-exposed mice when administered at doses of 20 and 10 to 30 mg/kg, respectively. ML-314 (30 mg/kg) also reduces methamphetamine self-administration in rats.Formal Name: 2-cyclopropyl-6,7-dimethoxy-4-[4-(2-methoxyphenyl)-1-piperazinyl]-quinazoline. CAS Number: 1448895-09-7.
