ML350

ML350 (CYM50202) is a highly potent OPRK1 antagonist with selectivity and broad biological applications. With IC₅₀ values of 9-16 nM, ML350 shows high selectivity for OPRK1, with selectivity of 219-382-fold and 20-35-fold relative to OPRD1 and OPRM1, respectively. ML350 exhibited favorable characteristics in in vivo pharmacokinetic analysis, including high passive membrane permeability and moderate human plasma protein binding. Extensive screening of ML350 against multiple ion channels, receptors, and transporters showed that it does not have adverse off-target effects.
