Wy 25093 is a novel, selective and potent inhibitor of the neuronal 5-hydroxytryptamine (5-HT) uptake process in vitro and in vivo. The compound was more potent than clomipramine and fluoxetine as an inhibitor of 5-HT uptake in vitro and did not significantly inhibit catecholamine uptake. In addition, Wy 25093 potentiated the behavioural syndrome induced by 5-hydroxytryptophan (5-HTP) and antagonised the hyperactivity produced by p-chloroamphetamine (P-CA). WY 25093 antagonised the (P-CA)-induced depletion of 5-HT in rat brain and reduced the probenecid-induced increase in rat brain 5-hydroxyindole-3-acetic acid (5-HIAA). Acute administration of the agent to rats resulted in reduced 5-HIAA levels without affecting 5-HT; chronic treatment with the compound produced decreases in the levels of both 5-HIAA and 5-HT. It is concluded that Wy 25093 is a selective and potent inhibitor of the neuronal re-uptake process for 5-HT both in vitro and in vivo, and may possess potential antidepressant activity.
Wy 25093是一种新型、具有选择性且强效的神经元5-羟色胺(5-HT)摄取过程抑制剂,在体外和体内均有此作用。作为5-HT摄取的抑制剂,该化合物在体外比氯米帕明和氟西汀更有效,且对儿茶酚胺摄取无明显抑制作用。此外,Wy 25093增强了5-羟色氨酸(5-HTP)诱导的行为综合征,并拮抗了对氯苯丙胺(P-CA)产生的多动。WY 25093拮抗了(P-CA)诱导的大鼠脑内5-HT耗竭,并降低了丙磺舒诱导的大鼠脑内5-羟吲哚-3-乙酸(5-HIAA)升高。对大鼠急性给药该药物导致5-HIAA水平降低,但不影响5-HT;用该化合物长期治疗会使5-HIAA和5-HT水平均下降。结论是,Wy 25093在体外和体内均是5-HT神经元再摄取过程的选择性强效抑制剂,可能具有潜在的抗抑郁活性。
