Does anyone know how long an aqueous solution of SCH 50911 ((2S)-(+)-5,5-Dimethyl-2-morpholineacetic acid), a GABAB receptor selective antagonist, can be stored and at what temperature? In addition, how long can a solution of NBQX (not the disodium salt), an AMPA/kainate receptor antagonist, dissolved in DMSO be stored and at what temperature?
