Desmethyl Levofloxacin, a metabolite of levofloxacin, is associated with a synthetic fluoroquinolone antibacterial drug that inhibits the super-coiling activity of bacterial DNA gyrase, thereby preventing DNA replication.
Levofloxacin sodium is a synthetic fluoroquinolones antibacterial. It inhibits the supercoiling activity of bacterial DNA gyrase, so that halting DNA replication.
Levofloxacin hydrochloride 是一种广谱的第三代氟喹诺酮类抗生素,是氧氟沙星的光学活性 L-异构体,具有抗菌活性。左氧氟沙星通过细菌细胞壁扩散并通过抑制 DNA 促旋酶(细菌拓扑异构酶 II)起作用,这是一种 DNA 复制、RNA 转录和细菌 DNA 修复所需的酶。 DNA 促旋酶活性的抑制导致细菌细胞生长受阻。
Levofloxacin mesylate 是一种口服有效的抗生素,抑制革兰氏阳性和阴性细菌。其作用机制为抑制 DNA 促旋酶 (DNA gyrase) 和拓扑异构酶 IV (topoisomerase IV)。Levofloxacin mesylate 适用于慢性牙周炎、气道炎症和 BK 病毒血症的研究,并具有抗正痘活性。
Antofloxacin is a well-tolerated, orally active, and broad-spectrum 8-amino-fluoroquinolone compound that exhibits potent antibacterial properties. It demonstrates superior activity against gyrA mutation-positive Helicobacter pylori strains, particularly in strains with mutations in the Asn87 position, when compared to levofloxacin. Additionally, Antofloxacin acts as a weak but reversible inhibitor of CYP1A2 and is clinically used to treat infections caused by various bacterial species.
