9H-Xanthene-9-carboxamide, N-[4-(trifluoromethyl)-2-oxazolyl]-

RO0711401 is a selective and orally active positive allosteric modulator of mGlu1 receptor with an EC50 of 56 nM[1][2]. RO0711401 (10 mg/kg; s.c.; once) causes a long-lasting improvement in motor performance, which is maintained to the same extent at least for 6 days[1].Systemic injection of RO0711401 is shown to reduce the frequency of spike-and-wave discharges in a rat model of absence epilepsy, and to improve motor signs in autoimmune encephalomyelitis (EAE) mice[1].
