ML335

Description: ML335 is a potent and selective activator of TREK-1/-2 and an agonist for OPRM1-OPRD1 (OPRM1: opioid receptor mu 1; OPRD1: delta opioid receptor) heterdimerization. ML335 selectively activates OPRM1-OPRD1 heterodimerization which may have potential use in the treatment of pain and alleviate unwanted effects associated with opiate use. The Scripps Research Institute Molecular Screening Center (SRIMSC) discovered ML335 as an agonist for OPRM1-OPRD1 heterdimerization with an EC50 of 403 nM, and selectivities vs. OPRM1, OPRD1, and HTR5A of 37, 2.7, and > 99, respectively. Heteromerization of OPRM1 with OPRD1 leads to the modulation of receptor binding and signaling properties. It has further been shown that the selective activation of the OPRM1-OPRD1 heteromer by a combination of OPRM1 agonist with OPRD1 antagonist can be blocked by antibodies that selectively recognize the heteromer.
