Pozanicline

Pozanicline (INN,^[1] codenamed ABT-089) is a drug developed by Abbott, that has nootropic and neuroprotective effects.^[2][3][4] Animal studies suggested it useful for the treatment of ADHD^[5] and subsequent human trials have shown ABT-089 to be effective for this application.^[6] It binds with high affinity subtype-selective to the α₄β₂ nicotinic acetylcholine receptors and has partial agonism to the α₆β₂ subtype,^[7][8] but not the α₇ and α₃β₄ subtypes familiar to nicotine. It has particularly low tendency to cause side effects compared to other drugs in the class.^[9][10]

Synthesis

Pozanicline is synthesized from 2-methyl-3-hydroxypyridine and Boc-L-Prolinol through a dehydration reaction followed by deprotection of the nitrogen atom of prolinol^[11]
