  Discovery of VU6027459: A First-in-Class Selective and CNS Penetrant mGlu₇ Positive Allosteric Modulator Tool Compound

  摘要：

  Herein, we report the discovery of the first selective and CNS penetrant mGlu(7) PAM (VU6027459) derived from a "molecular switch" within a selective mGlu(7) NAM chemotype. VU6027459 displayed CNS penetration in both mice (K-p = 2.74) and rats (K-p = 4.78), it was orally bioavailable in rats (%F = 69.5), and undesired activity at DAT was ablated.
