Abstract

The invention relates to an application of Orciprenaline which has bactericidal, antibacterial or bacteriostatic activity, and application of the Orciprenaline in preparation of bactericidal, antibacterial or bacteriostatic products. A method for screening antibacterial drugs comprises the following steps: constructing a menA defective strain; transferring plasmids containing menA into the defective strain; and screening the medicine to obtain the antibacterial drug. The method has the beneficial effects that the menA defective strains are prepared for the first time, and the drugs are tried to be designed and screened by taking the menA defective strains as targets; it is found that the Orciprenaline has a specific inhibition effect on an important enzyme MenA in a bacterial respiratory chain, which indicates that Orciprenaline has a potential antibacterial effect. The preparation belongs to new use of old drugs, and the drug development period is greatly shortened.
