The present invention relates to novel cephalosporin derivatives represented by Chemical Formula 1.
Wherein, X, Y, L, R
1
, and R

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.
本发明涉及由化学公式1表示的新型头孢菌素衍生物。其中,X、Y、L、R1和R2与发明描述中定义的相同。本发明还涉及包含由化学公式1表示的新型头孢菌素衍生物、前药、水合物、溶剂化物、异构体或药用可接受盐作为有效成分的药物抗生素组合物。根据本发明,新型头孢菌素衍生物、前药、水合物、溶剂化物、异构体或药用可接受盐作为广谱抗生素耐药、低毒性的有效成分,特别是在革兰氏阴性细菌中,可以具有强大的抗菌活性。
