The application provides artemordins A-S (compounds 1-19), a pharmaceutical composition thereof, and a preparation method and application thereof, and belongs to the technical field of drugs. The 19 sesquiterpene dimers shown in structural formula (I) of the application have cytotoxic activity on human hepatoma cell strains HepG2, Huh7 and SK-Hep-1, can be combined with a pharmaceutically acceptable carrier or excipient to form a pharmaceutical composition, and can be used for preparing an anti-hepatoma drug.

This invention specifically relates to a composite polymer antibacterial agent, its preparation method, and its application, belonging to the field of antibacterial materials technology. The antibacterial agent, by weight percentage, comprises a core component PQ-1 (0.01%~0.1%), a synergistic component polyhexamethylene biguanide (PHMB) (0.005%~0.05%), a synergistic component polyaminopropyl biguanide (PAPB) (0.005%~0.05%), and the balance being solvent. This invention, through the synergistic combination of PQ-1 and the two synergistic components, can reduce the minimum inhibitory concentration (MIC) against typical microorganisms by more than 75% while reducing the amount of PQ-1 by 50%~80%, achieving optimized protection of the antibacterial efficacy concentration of PQ-1, while also possessing the advantages of broad spectrum, stability, mildness, and low toxicity. Its preparation process is simple and can be widely applied in ophthalmic preparations, cosmetics, and other fields, demonstrating extremely high practical value.
