The present invention relates to novel cephalosporin derivatives represented by Chemical Formula 1.
Wherein, X, Y, L, R1, and R2 are as same as defined in the description of the invention.
The present invention also relates to pharmaceutical antibiotic compositions comprising a novel celphalosporin derivative represented by Chemical Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient.
According to the present invention, novel cephalosporin derivatives, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient for the broad spectrum of antibiotic resistant, low toxicity, particularly in Gram-negative bacteria, which can be useful with strong antimicrobial activity.
本发明涉及化学式 1 所代表的新型头孢菌素衍生物。
其中,X、Y、L、R1 和 R2 与本发明描述中所定义的相同。
本发明还涉及药物抗生素组合物,该组合物包含化学式 1 所代表的新型头孢菌素衍生物、其原药、其水合物、其溶液、其异构体或其药学上可接受的盐作为有效成分。
根据本发明,新型头孢菌素衍生物、其原药、其水合物、其溶物、其异构体或其药学上可接受的盐作为有效成分,可用于广谱抗抗生素、低毒性,特别是革兰氏阴性菌,具有很强的抗菌活性。
