MedKoo CAT#: 532985

CAS#: 748758-45-4

Description: YM 298198 Hydrochloride is a non-competitive antagonist with high affinity and selectivity for mGlu1 receptors (Ki = 19 nM). YM 298198 Hydrochloride is inactive at other mGlu receptor subtypes (mGlu2-7), ionotropic receptors and glutamate transporters (IC50 > 10 μM). It inhibits glutamate-induced IP production more potently than CPCCOEt (IC50 values are 16 nM and 6.3 μM respectively).
