The invention provides a pyrimidine compound and a preparation method and application thereof. The pyrimidine compound has a structure as shown in formula I, and R1 is selected from at least one of hydrogen, halogen, substituted or unsubstituted C1-6 alkyl, substituted or unsubstituted C1-6 alkoxy, phenyl, cyano, aldehyde and nitro; R2 is selected from hydrogen, halogen, amino substituted by C1-6 alkyl, and substituted or unsubstituted azacycloalkyl; R3 is located at the third position and the fifth position of a benzene ring and is independently selected from trifluoromethyl or fluorine respectively; X is selected from one of oxygen, sulfur and nitrogen; and A, B, C and Z are independently selected from carbon or nitrogen. The pyrimidine compound provided by the invention is an effective SecA inhibitor, has broad-spectrum antibacterial activity, and has good antibacterial activity on drug-resistant strains such as MRSA, MRSE, VISA, VRE and the like.

SecA, a key component of the bacterial Sec-dependent secretion pathway, is an attractive target for the development of new antimicrobial agents. Through a combination of virtual screening and experimental exploration of the surrounding chemical space, we identified a hit bistriazole SecA inhibitor, SCA-21, and studied a series of analogues by systematic dissections of the core scaffold. Evaluation of these analogues allowed us to establish an initial structure-activity relationship in SecA inhibition. The best compounds in this group are potent inhibitors of SecA-dependent protein-conducting channel activity and protein translocation activity at low- to sub-micromolar concentrations. They also have minimal inhibitory concentration (MIC) values against various strains of bacteria that correlate well with the SecA and protein translocation inhibition data. These compounds are effective against methicillin-resistant Staphylococcus aureus strains with various levels of efflux pump activity, indicating the capacity of SecA inhibitors to null the effect of multidrug resistance. Results from studies of drug-affinity-responsive target stability and protein pull-down assays are consistent with SecA as a target for these compounds. One stone, several birds! The SecA inhibitors discovered in this study are broad-spectrum antimicrobials with the intrinsic ability to null the effect of efflux pumps. They are therefore effective against multidrug-resistant bacterial strains, can inhibit virulence factor secretion, and are very active against strains of bacteria that are resistant to antibiotics in current use, including vancomycin.
