Hydroxytacrine maleate, a bioactive monohydroxylated metabolite of cholinesterase inhibitor, is a potential Alzheimer's therapeutic of low toxicity [1]. Hydroxytacrine maleate exhibited biochemical and pharmacological profile similar to tacrine (THA) except that the far less liver toxicity in humans. The prolonged use of tacrine has been associated with liver toxicity[1, 2].
Hydroxytacrine maleate is a parasympathomimetic and a centrally acting cholinesterase inhibitor (anticholinesterase). As the first cholinesterase inhibitor approved for the treatment of AD, tacrine was marketed under the trade name Cognex [3]. Through hydroxylation of benzylic carbon by CYP450 in the liver, tacrine has been metabolized into metabolite 1-hydroxy-tacrine (velnacrine) [4]. It has also been shown that maleate is an inhibitor of AChE [5].
