 Use of ML314


ML314 is a potent molecule agonist of NTR1 (EC50 = 1.9 μM); showed good selectivity against NTR2 and GPR35, but did not stimulate Ca2+ mobilization.IC50 value: 1.9 uM (EC50) [1]Target: NTR1 agonistMedicinal chemistry optimization of MLS-0233108 led to ML314, the most potent molecule in this second series that exhibited full agonist behavior (100 %) on NTR1 (EC50 = 1.9 μM). ML314 showed good selectivity against NTR2 and GPR35, but did not stimulate Ca2+ mobilization. ML314 is potentially a biased agonist operating via the β-arrestin pathway rather than the traditional Gq coupled pathway. Signaling mediated by β-arrestin has distinct biochemical and functional consequences that may lead to physiological advantages as described below. This probe report describes the discovery and properties of ML301 and summarizes the HTS and follow-up campaign, which identified ML314.
