    Product Description

    HexylHIBO is an antagonist of group I metabotropic glutamate receptors (mGluRs; Kbs = 140 and 110 µM for mGluR1α and mGluR5a, respectively).1 It is selective for group I mGluRs over mGluR2 (group II) and mGluR4a (group III) (Kbs = >1,000 µM for both), as well as AMPA, NMDA, and kainate receptors (IC50s = >100 µM for all). HexylHIBO (6.3 and 12.5 mg/kg, i.c.v.) inhibits NMDA-induced seizures in mice. It also potentiates increases in plasma adrenocorticotropic hormone (ACTH) levels in a rat model of restraint stress.2
