The invention discloses 1-butyl-2-hydroxyl aralkyl piperazine derivatives and their use as antidepressants. The derivatives of the present invention have triple inhibition effect on the reuptake of 5-HT, NA and DA, and can be administrated to the patients in need thereof in form of composition by route of oral administration, injection and the like. Compared with clinically currently used dual targets antidepressants (such as venlafaxine), said derivatives may have stronger antidepression effect, broader indications, faster onset and lower neurotoxicity and side reaction; and said derivatives have stronger antidepression activity, lower toxicity, higher bioavailability, longer half life and better druggablity, compared with aryl alkanol piperazine derivatives and optical isomers thereof disclosed in prior art. The 1-butyl-2-hydroxyl aralkyl piperazine derivative is the free alkali or its salt of a compound of formula below:
该发明公开了1-丁基-2-羟基芳基哌嗪衍生物及其作为抗抑郁药物的用途。本发明的衍生物对5-HT、NA和DA的再摄取具有三重抑制作用,并可以以口服、注射等形式组成物的方式给予需要的患者。与目前临床使用的双靶抗抑郁药物(如文拉法辛)相比,这些衍生物可能具有更强的抗抑郁作用,更广泛的适应症,更快的起效作用,以及更低的神经毒性和副作用;与先前公开的芳基烷醇哌嗪衍生物及其光学异构体相比,这些衍生物具有更强的抗抑郁活性,更低的毒性,更高的生物利用度,更长的半衰期和更好的药物可用性。1-丁基-2-羟基芳基哌嗪衍生物是以下化合物的游离碱或其盐:
