| Bioactivity | Muscimol (Agarin), a psychoactive isoxazole, is a selective neurotransmitter GABA agonist. Muscimol Binds GABAA on both high- and low-affinity sites (Kd=10 and 270 nM, respectively), stimulating chloride efflux with an EC50 value of 200 nM. Muscimol passes the blood-brain barrier (BBB) and has memory-disrupting effects[1]. | ||||||||||||
