ML353 is a selective ligand of mGlu5 silent allosteric modulator (SAM) with an Ki value of 18.2 nM. ML353 improves the affinity of common allosteric sites, 20-fold higher than the previous mGlu5 SAM tool compound 5mpep. ML353 has potential applications in solving the intrinsic activity of SAM in vivo or as a agent blocker[1]. ML353 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
