代谢
在大鼠口服给药后,使用DPX-JW062和DPX-MP062研究了其代谢情况。大部分剂量在96小时内被排泄。发生了广泛的代谢,形成了众多的次要代谢物。在尿液中,代谢物是裂解产物(茚满环或三氟甲氧基苯环产物),而在粪便中,主要代谢物保留了这两个结构单元。主要的代谢反应包括茚满环的羟基化,从氨基氮上水解羧甲基基团,以及噁二唑环的开环,从而产生裂解产物。
Metabolism in rats after oral dosing was studied using both DPX-JW062 and DPX-MP062. Most of the dose was excreted within 96 hr. Extensive metabolism to numerous minor metabolites occurs. In urine, metabolites were cleaved products (indane or trifluoromethoxyphenyl ring products), whilst in feces, major metabolites retained both these moieties. Major metabolic reactions included hydroxylation of the indane ring, hydrolysis of the carboxymethyl group from the amino nitrogen, and opening of the oxadiazine ring, which gave rise to cleaved products.
