Abstract

The invention provides an application of patchoulenone or a derivative thereof in preparing medicines for treating bacterial infectious diseases. Furthermore, the invention provides a pharmaceutical composition for treating the bacterial infectious diseases. The patchoulenone has an excellent activity on inhibiting pathogenic bacteria such as staphylococcus and opportunistic pathogenic bacteria, and can effectively treat bacterial infectious diseases; and the patchoulenone can effectively inhibit methicillin-resistant drug-resistance bacteria, thus providing a new choice for clinical medication.

Description

Technical field [0001] The invention relates to a new use of patchoulione and its derivatives, in particular to the use in the preparation of drugs for treating bacterial infectious diseases. Background technique [0002] Bacterial infectious diseases refer to diseases caused by bacterial infections. Among the common clinical pathogens, there are more Gram-negative bacteria, such as Escherichia, Enterobacter and Pseudomonas bacteria, and Gram-positive bacteria, such as Staphylococcus and intestine Coccus bacteria. [0003] At present, most commonly used drugs for bacterial infectious diseases are antibiotics and broad-spectrum antibacterial drugs, such as imipenem, second-selected sulbactam, vancomycin, and second-selected nitrofurantoin, which have large side effects and will cause large-scale use. The development of drug resistance leads to the emergence of super bacteria. Methicillin-resistant Staphylococcus aureus is a kind of super bacteria, which is only sensitive to vanco...
