Description: ML-314 is a brain penetrant nonpeptidic β-arrestin biased ggonist of the neurotensin NTR1 receptor, which exhibits full agonist behavior against NTR1 (EC50 = 2.0 μM) in the primary assay and selectivity against NTR2. The effect of ML314 is blocked by the NTR1 antagonist SR142948A in a dose-dependent manner. Unlike peptide-based NTR1 agonists, ML314 has no significant response in a Ca2+ mobilization assay and is thus a biased agonist that activates the β-arrestin pathway rather than the traditional Gq coupled pathway. This bias has distinct biochemical and functional consequences that may lead to physiological advantages. ML314 displays good brain penetration in rodents, and studies examining its in vivo properties are underway.
