The metabolites of 9-fluoro-6, 7-dihydro-8-(4-hydroxy-1-piperidyl)-5-methyl-1-oxo-1H, 5H-benzo[i, j]quinolizine-2-carboxylic acid (OPC-7251) (1), which has a potent antiabacterial activity against gram-positive bacteria, characteristically Propionibacterium acnes, were synthesized to confirm their structures and to examine their antibacterial activity. The structures of three major metabolites (2, 3a and 4) were identified by means of comparison with the synthetic compounds. The antibacterial activity of the metabolites (2, 3a and 4) was found to be lower than that of 1.
9-氟-6, 7-二氢-8-(4-羟基-1-哌啶基)-5-甲基-1-氧代-1H, 5H-苯并[i, j]喹嗪-2-甲酸的代谢物( OPC-7251) (1) 对革兰氏阳性菌(特别是痤疮丙酸杆菌)具有有效的抗菌活性,其合成是为了确认其结构并检查其抗菌活性。通过与合成化合物的比较,鉴定了三种主要代谢物(2、3a 和 4)的结构。发现代谢物(2、3a和4)的抗菌活性低于1。
