A7111 Acepromazine maleate ≥98% (HPLC) Acepromazine is a phenothiazine antipsychotic comonly used as a veterinary drug (horses, dogs and cats). The compound is an analogue antipsychotic drug chlorpromazine (#C8138). The drug is thought to block receptors of dopamine in the brain. Recently it was discover that the compound inhibits ABCG2 transported protein, which overexpression in tumors is associated with drug resistance.
