Description: BTRX-335140, also known as CYM-53093, a potent and selective KOR antagonist with IC50 (KOR)=0.8 nM. BTRX-335140 endowed with favorable in vitro ADMET and in vivo pharmacokinetic profiles and medication-like duration of action in rat pharmacodynamic experiments. Orally administered CYM-53093 showed robust efficacy in antagonizing KOR agonist-induced prolactin secretion and in tail-flick analgesia in mice. CYM-53093 exhibited a broad selectivity over a panel of off-target proteins.

Additional Information

κ opioid receptor (KOR) antagonists are potential pharmacotherapies for the treatment of migraine and stressrelated mood disorders including depression, anxiety, and drug abuse, thus the development of novel KOR antagonists with an improved potency/selectivity profile and medication-like duration of action has attracted the interest of the medicinal chemistry community.

This compound is in Phase 1 clinical trials for the treatment of neuropsychiatric disorders wherein dynorphin is thought to contribute to the underlying pathophysiology.
