Ipidacrine (hydrochloride)

Ipidacrine (NIK-247; Amiridine) hydrochloride is orally active and blood-brain-barrier-penetrant AChE and BuChE inhibitors with IC₅₀ values of 1 μM and 1.9 μM, respectively, which is also a partial agonist of M2-cholinergic receptors and a reversible cholinesterase inhibitor. Ipidacrine hydrochloride has a stimulating effect on neuromuscular transmission and excitation along the nerve fibres with a moderately anti-pain effect. Ipidacrine hydrochloride is an aminopyridines and is structurally similar to Tacrine (HY-111338).
