R-R-0414 Cyclo(L-Pro-L-Trp) Brevianamide F/Cyclo(L-Pro-L-Trp)/CAS:38136-70-8, belongs to a class of naturally occurring 2,5-diketopiperazines. It is the simplest member and the biosynthetic precursor of a large family of biologically active prenylated tryptophan-proline 2,5-diketopiperazines that are produced by the fungi A.fumigates and Aspergillus sp. It has been isolated from the bacterium Streptomyces sp. strain TN58 and shown to possess activity against two Gram-positive bacteria, S.aureus and Micrococcus luteus, and has also been isolated from Bacillus cereus associated with the entomopathogenic nematode, Rhabditis (Oscheius) sp. and shown to have antifungal activity against T. rubrum, C. neoformans and C. albicans, better than amphotericin B price>
R-R-0422 Cyclo(L-Phe-trans-4-hydroxy-L-Pro) Cyclo(L-Phe-trans-4-hydroxy-L-Pro)/Cyclo(L-phenylalanyl-trans-4-hydroxy-L-proline)/CAS 118477-06-8 is a reference material for HPLC standards. This natural product is isolated from the plant Cyclopia subternata, which is found in the subtropical and warm temperate regions of Australia and New Zealand. It has been shown to have bioactive properties and a number of potential applications in drug discovery, screening, and quality control. Cyclo(L-Phe-trans-4-hydroxy-L-Pro) has been shown to inhibit the growth of several bacterial strains, including Staphylococcus aureus, Salmonella enterica serovar Typhimurium, Enterobacter aerogenes, Escherichia coli O157:H7, Klebsiella pneumoniae ATCC 700603, and Pseudomonas aeruginosa ATCC 27853. price>
R-R-0502 LL-37, Antimicrobial Peptide, human LL - 37, Antimicrobial Peptide, human/CAS:597562-32-8 from ruixi.LL-37 is a human antimicrobial peptide of the cathelicidin family and corresponds to the 134-170 segment of human cationic antimicrobial protein 18 (hCAP18). It plays an important role in the first line of defense against local infection and systemic invasion of pathogens at sites of inflammation and wounds. Cytotoxic to both bacterial and normal eukaryotic cells, LL-37 is significantly resistant to proteolytic degradation in solution. price>
R-R-0581 Ketolide resistance Peptide MRFFV This peptide (MRFFV) confers resistance to ketolide antibiotics, preventing antibiotic binding of bacterial ribosomes and allowing the continuation of protein synthesis. price>
R-R-0594 SMAP 29, Sheep Myeloid Antimicrobial Peptide 29 SMAP 29 (sheep) is a 29 amino acid sheep myeloid antimicrobial peptide (SMAP) which is a cathelicidin with an alpha helical structure and the ability to disrupt cell membranes. SMAP 29 (sheep) acts as a broad spectrum antimicrobial activity against gram negative and gram-positive bacteria and fungi and has been investigated as a treatment for acute and chronic respiratory infections. price>
