3 results about "Plectasin" patented technology

Plectasin is an antibiotic protein found by Novozymes in the mushroom Pseudoplectania nigrella. Plectasin belongs to the antimicrobial peptide class called Defensins, which is also present in invertebrates such as flies and mussels. Pre-clinical tests in mice have shown promising results in that multiresistant bacteria have problems mutating resistance against plectasin, which acts by directly binding the bacterial cell-wall precursor Lipid II. At the end of 2008, Novozymes signed a global licensing agreement with Sanofi-Aventis for the further development and marketing of NZ2114, a derivative of plectasin, as a treatment for gram-positive bacterial infections, e.g. Streptococcus and Staphylococcus which are resistant to all existing antibiotics.

Drug-loaded nanoparticles as well as preparation method and application thereof

The invention discloses a drug-loaded nanoparticle as well as a preparation method and application thereof. The drug-loaded nanoparticle can be used for treating triple negative breast cancer, and specifically comprises a magnetic nanoparticle, an active component loaded in the magnetic nanoparticle, and an erythrocyte membrane coating the magnetic nanoparticle, wherein the active ingredients are selected from one or more of piperlongumine, polyphyllin II, erianin, pseudolaric acid, 6-gingerol, ginkgetin, solasonine, cucurbitacine B and lycorine. In practical application, the drug-loaded nanoparticles have good biological safety, long circulation capability and high tumor retention capability, and can generate efficient killing and treatment effects on triple-negative breast cancer by inducing cell apoptosis.

Antimicrobial peptide Ple-AB, its preparation method and application

This invention relates to the field of antimicrobial peptide technology, and particularly to the antimicrobial peptide Ple-AB, its preparation method, and its applications. Using the fungal defensin Plectasin as a template, this invention designs and modifies the antimicrobial peptide Ple-AB. Compared with Plectasin, this antimicrobial peptide exhibits significantly higher antimicrobial activity and better bactericidal effects against Gram-positive bacteria; it also shows higher stability, particularly excellent resistance to trypsin; and its fermentation expression level is significantly improved. Furthermore, this antimicrobial peptide has very low hemolytic activity and cytotoxicity, making it suitable for development in antimicrobial drugs, additives, cosmetics, health products, and other fields, with broad application value and market prospects.
