In this study, we compared the enzymatic reduction of 10 drugs with a ketone group by homogeneous carbonyl reductase, aldehyde reductase and three dihydrodiol dehydrogenases of human liver cytosol. At least one and in some cases all of the three dihydrodiol dehydrogenases reduced each of the ten drugs. Among these naloxone, naltrexone, befunolol, ethacrynic acid and ketoprofen were substrates specific
在这项研究中,我们比较了人肝细胞溶质的均相羰基还原酶,醛还原酶和三种二氢二醇脱氢酶对10种带有酮基的药物的酶促还原作用。三种二氢二醇脱氢酶中至少一种,在某些情况下,全部还原了十种药物。在这些纳洛酮中,纳曲酮,倍氟洛尔,乙炔酸和酮洛芬是脱氢酶特异的底物。羰基还原酶和/或醛还原酶大大降低了其他药物-氟哌啶醇,甲吡酮,洛索洛芬,柔红霉素和乙酰己酰胺的含量。二氢二醇脱氢酶还显示氟哌啶醇和洛索洛芬的Km值低于羰基还原酶的Km值。结果表明,三种二氢二醇脱氢酶以及两种还原酶,
