BIBN 99 is an antagonist of mACh receptors. Specifically, it is selective for the M2 type. [1]

Effects

During research, it was observed that BIBN 99 was able to diminish the cognitive deficits caused by injury. [2] Another also came to the conclusion that the compound could provide cognitive improvements. [3] The cognitive effects could possibly be caused by the increased release of acetylcholine, a neurotransmitter. [4]
