Description

Rislenemdaz, also known as MK-0657 or CERC‐30, is an orally active, selective NMDA receptor subunit 2B (NR2B) antagonist which was a study for the treatment of Parkinson's disease and major depressive disorder (MDD). The data from the phase I clinical trials have shown that drug was not effective in improving motor symptoms in patients with Parkinson disease. In case of using this drug to treat MDD, in spite of the Missing Primary Endpoint in phase II clinical trials, it was shown, that MK-0657 had possessed a potential clinical meaningfulness, that is why it was suggested to continue studying it for MDD patients.

In Vitro Use Guide
It was measured the functional activity and selectivity of CERC‐301 (MK-0657) for NMDA receptors. CERC‐301 inhibited calcium influx into agonist‐stimulated NMDA‐GluN1a/GluN2B L(tk‐) cells with an IC50 of 3.6 nmol L−1 but had no effect on calcium influx into agonist‐stimulated GluN1a/GluN2A cells at concentrations up to 30,000 nmol L−1 (30 μmol L−1). CERC‐301 exhibited no remarkable activity when tested in enzyme and radioligand binding assays at concentrations equal to and greater than 10 μmol L−1. CERC‐301 exhibited at least 1000 × selectivity for the GluN2B receptor versus all targets tested, including the hERG potassium channel. CERC‐301 also exhibited minimal activity against sigma‐type receptors at 10 μmol L−1 (sigma‐1, sigma‐2, and nonspecific).
