Problems solved by technology
[0008] The technical problem to be solved by the present invention is cyclopyrimidine or stereoisomers, prodrugs, pharmaceutically acceptable salts, double salts or solvated cyclopyrimidines, which are representative active ingredients of aromatic heterocyclic pyrimidine derivatives and analogs. The drugdelivery system of Naiping compound as the active ingredient is studied, and a safe drugdelivery system suitable for it is obtained, which solves technical problems such as a very narrow therapeutic window and poor safety in clinical application. For aromatic heterocyclic pyrimidine derivatives and similar Modified the chemical structure of the drug to obtain cyclopyridine. After the safety and effectiveness of cyclopyridine were studied, they were better than vancomycin and ciprofloxacin, and the antibacterial spectrum was better than that of vancomycin and ciprofloxacin. Broad, solubility increased significantly

Abstract
The invention relates to medicament combination preparation of medicinal compound taking cy-ethyl razepam medicinal compound containing cy-ethyl razepam or stereoisomer, pro-medicinal, medicinal salt, complex salt or / and salvation as effective constituent. The medicament combination preparation adopts the technical scheme that the cy-ethyl razepam medicinal compound, which has a general formula (1) structure and contains the cy-ethyl razepam or the stereoisomer, the pro-medicinal, the medicinal salt, the complex salt and the solvation, is taken as the effective constituent and forms the medicament combination preparation with a medicament carrier capable of being received on the pharmacy; and the preparation formulation is any preparation formulation said on the pharmacy. The invention also discloses an application of the medicament combination preparation in the process of treating the infection of bacteria taken as gram-positive bacteria like staphylococcus, pneumococcus, enterococcus faecalis, streptococcus, streptococcus bovis, streptococcus pneumoniae, peptostreptococcus, festering streptococcus pneumoniae, festering streptococcus pneumoniae, streptococcus pyogenes, streptococcus agalactiae, viridans streptococci, streptococcus bovis, streptococcus agalactiae B, group green streptococcus, corynebacterium diphtheriae and other bacteria.
