描述：

Marbofloxacin是一种有效的抗生素，抑制细菌DNA复制。Marbofloxacin 是 Fluoroquinolone抗菌试剂，专门用于兽用。Marbofloxacin 作用于广谱需氧革兰氏阴性和一些革兰氏阳性菌，及支原体属，具有高度杀菌活性。作为第三代Fluoroquinolone, Marbofloxacin 也主要靶向作用于复制和转录酶，如DNA解旋酶和拓扑异构酶 IV,这两者对细菌存活都非常重要。

溶解性：DMSO ：2 mg/mL (5.51 mM)

体外研究：

Marbofloxacin is a fluoroquinolone antimicrobial agent developed exclusively for veterinary use. Marbofloxacin exhibits high bactericidal activity against a broad spectrum of aerobic Gram-negative and some Gram-positive bacteria, as well as Mycoplasma spp. As the third generation fluoroquinolone, Marbofloxacin also mainly targets replication and transcription enzymes such as DNA gyrase and topoisomerase IV, which are both essential for bacterial viability. Marbofloxacin has a mycoplasmacidal effect during the exponential phase but not during the lag phase, in both the M. hyopneumoniae 116 wild-type strain and a clone isolated 4 days post-marbofloxacin treatment in vivo at the therapeutic dose. Marbofloxacin significantly kills Leishmania promastigotes and intracellular amastigotes in a dose-dependent manner, more efficient than meglumine antimoniate and sodium stibogluconate. After treatment with Marbofloxacin, macrophages acquire resistance to infection and enhanced antileishmanial activity through the NO synthase pathway.

体内研究：Marbofloxacin treatment at the therapeutic dose does not eliminate M. hyopneumoniae, with 87.5 to 100% of the pigs still positive at the end of the assays, and is not effective in significantly reducing clinical signs. Nevertheless, Marbofloxacin treatment seems to decrease the lung lesion scores. Administration of Marbofloxacin at 6 mg/kg once daily for 7 days in a Staphylococcus aureus infection in tissue cages in ponies is not effective for the elimination of S. aureus infections from secluded sites.
