Oxprenolol (1), like related beta-adrenergic antagonists, undergoes oxidative N-dealkylation to form the corresponding 3-aryloxypropane-1,2-diol (2), 3-aryloxylactic acid (3), and 2-aryloxyacetic acid (4) metabolites. Compounds 3 and 4 were synthesized by conversion of 2-allyloxyphenol (5) to the aryloxyacetaldehyde 6 and subsequent elaboration to the desired acids. Both acids (3 and 4) and glycol
像相关的β-肾上腺素拮抗剂一样,奥曲萘洛尔(1)经历N-脱烷基氧化反应,形成相应的3-芳氧基丙烷-1,2-二醇(2),3-芳氧基乳酸(3)和2-芳氧基乙酸(4)代谢产物。通过将2-烯丙氧基苯酚(5)转化为芳氧基乙醛6并随后精制为所需酸来合成化合物3和4。在大鼠体内和体外在大鼠肝脏9000 X g上清液中,酸(3和4)和乙二醇2均被确认为由1形成的代谢产物。由等摩尔量的(2S)-1-d0和(2R)-1-d2组成的1的假外消旋物的孵育表明,2和3主要由(2S)-1产生,S / R比约为5:1和2:1。另一方面,乙酸衍生物4大约均等地由1的两种对映体产生。
