metabolic activation rates in the synthesized alcohol ester prodrugs. In addition, haloperidol acetate and haloperidol 2-methylbutanoate were hydrolyzed as slowly as haloperidol decanoate. The results suggested that haloperidol prodrugs with a small chain or a branched chain are useful as prodrugs for sustained release. The metabolic activation rate of the enol ester prodrug in HLM solution was similar
合成了两种对羟基或羰基进行了化学修饰的氟哌啶醇前药,并在人肝微粒体(HLM)溶液,人小肠微粒体(HIM)溶液和人重组羧酸酯酶(hCES)的溶液。HLM溶液中的醇酯前药的代谢活化率与hCES2溶液中的相似,而氟哌啶醇戊酸酯和氟哌啶醇己酸酯在合成的醇酯前药中具有较高的代谢活化率。此外,乙酸氟哌啶醇和氟哌啶醇2-甲基丁酸酯的水解速度与氟哌啶醇癸酸酯一样慢。结果表明具有小链或支链的氟哌啶醇前药可用作持续释放的前药。
