1-Hydroxypiperazine dihydrochloride 7 was prepared and it was applied to the syntheses of new pyridone carboxylic acid antibacterial agents (PCA-antibacterial agents). 1-Cyclopropyl-6,8-difluoro-1,4-dihydro-7-(4-hydroxypiperazin-1-yl)-4-oxoquinoline-3-carboxylic acid 13 showed the most potent antibacterial activity.
制备了1-羟基哌嗪二盐酸盐7,并将其用于合成新的吡啶酮羧酸抗菌剂(PCA-抗菌剂)。1-环丙基-6,8-二氟-1,4-二氢-7-(4-羟基哌嗪-1-基)-4-氧代喹啉-3-羧酸13具有最强的抗菌活性。
