Discovery of VU0467319: an M Positive Allosteric Modulator Candidate That Advanced into Clinical Trials.

Herein we detail the of VU0467319 (VU319), an M Positive Allosteric Modulator (PAM) clinical candidate that successfully completed a Phase I Single Ascending Dose (SAD) clinical trial. VU319 () is a moderately potent M PAM (M PAM EC = 492 nM ± 2.9 nM, 71.

Discovery of VU2957 (Valiglurax): An mGlu Positive Allosteric Modulator Evaluated as a Preclinical Candidate for the Treatment of Parkinson's Disease.

Herein, we report the discovery of a novel potent, selective, CNS penetrant, and orally bioavailable mGlu PAM, VU0652957 (VU2957, Valiglurax). VU2957 possessed attractive and pharmacological and DMPK properties across species. To advance toward the clinic, a spray-dried dispersion (SDD) formulation of VU2957 was developed to support IND-enabling toxicology studies.
