The MMQ compound is NOT likely to be an antagonist....quite the opposite IMO. AGONIST activity at AMPArs
Look at methyl-methaqualone thing came out but caused a lot of people tremors and at higher doses seizures. Pretty sure methaqualone has some, but lower AMPAR agonist effects. Its unusual for a GABAa agonist (PAM) to cause seizure which MQ can at overdose levels, convulsions are a feature of MQ ods as well generally iirc. the formmuscimol which is atypical of these drugs and is complex in that its usually taken in the form of fly amanita, or fly agaric, or occasionally panther cap but that contains yet other, and highly potent toxins similar to acromelic acids, and with femtomolar affinity for their target excitatory amino acid receptor, kainate receptors in the spine i believe)
For the barb lover-Not yet had MQ but soon i hope. Ethchlorvynol and 1-ethynylcyclohexan-1-ol are on my to do list when i haven't as many other projects begging stirplate time.
I suggest chlormethiazole, about the one still readily had barb site ligand. I'm prescribed it, comes as thick, tough walled gelcaps of a funky smelling and tasting freebaseusually, syrup exists but never had it. if synthing it from thiamine, don't bother trying to salt it, waste of time and effort, its notorious for lack of forming solid salts, ethanedisulfonate is the only pharm one or indeed salt iv'e heard of. Taste initially bad but it grows on one with use, to the extent when i take it as heminevrin capsules rather than just the liquid freebase.
