The invention relates to multi-functional antibiotic agents formed from antibiotics conjugated to microbial membrane disrupting peptides. These antibiotic-peptide conjugates are designed so that the conjugate simultaneously functions as a membrane disrupter and a metabolic inhibitor. In illustrative embodiments of the invention, the peptide of the conjugate causes the membrane of a bacteria to become permeable to the conjugate, and the antibiotic of the conjugate functions as a metabolic inhibitor by binding to bacterial ribosomes.
这项发明涉及由抗生素共轭到微
生物膜破坏肽形成的多功能抗生素剂。这些抗生素-肽共轭物被设计成共轭物同时作为膜破坏剂和代谢
抑制剂。在该发明的示例实施例中,共轭物的肽使细菌的膜对共轭物变得渗透性,并且共轭物的抗生素通过结合细菌
核糖体而起到代谢
抑制剂的作用。
