R-M-149 Beauvericin,CAS:26048-05-5 Beauvericin is a mycotoxin produced by various fungi including Fusarium spp. and Beaveria bassiana. As a cyclic hexadepsipeptide belonging to the enniatin antibiotic family, beauvericin contains three D-hydroxyisovaleryl and three N-methylphenylalanyl residues. Beauvericin was one of the active constituents of B. bassiana and was confirmed to have antibacterial and antifungal activities. price>
R-M-150 Polybia-MP1 trifluoroacetate salt,CAS :872043-01-1 Polybia-mp1 is a broad-spectrum bactericidal peptide extracted from wasp, which has the advantages of non hemolytic and non cytotoxic.Polybia-mp1 used in α - helix structure can form a stable monolayer in vivo, close to the membrane surface, change the osmotic pressure, and has the effect of killing bacteria. For polybia-mp1, the balance between overall attractive and repulsive interactions can be fine tuned by hydrodynamic strength and pH, and since this effect is related to lysine and aspartic acid, similar effects may occur in other peptide sequences containing these residues. price>
R-M-166 Extracellular Death Factor trifluoroacetate salt,CAS:960129-66-2 EDF is a quorum-sensing factor for mazEF-mediated cell death in E.coli. It may be a lead for a new class of antibiotics that specifically trigger bacterial cell death.Extracellular death factor (EDF) is a linear pentapeptide that activates the cell death pathway in a subset of communicating cells. Programmed cell death in bacteria is dependent on a system of cell-to-cell communication termed quorum sensing. It is sensitive to extreme pH, high temperatures, and other cellular stress. EDF has been shown to trigger cell death at 2.5 ng/ml which significantly reduces population size in some E. coli cultures. price>
R-M-167 Lactoferricin B25 trifluoroacetate salt,CAS:146897-68-9 The antimicrobial peptide lactoferricin B25 is a fragment of cow milk protein lactoferrin. The peptide exhibits potent dose-dependent and time-dependent anticancer activity against human stomach cancer cell cultures via apoptosis and autophagy.LFcinB25 is expected to yield novel anticancer drugs. price>
R-M-168 Parasin I trifluoroacetate salt The 19 amino acid peptide KGRGKQGGKVRAKAKTRSS was isolated from the epithelial mucosal layer of the injured catfish, Parasilurus asotus. Parasin I showed strong antimicrobial activity, about 12-100 times more potent than magainin II, against a wide spectrum of microorganisms, without any hemolytic activity.Parasin I is a histone H2-derived antimicrobial peptide found in Parasilurus catfish. Parasin I is produced by matrix metalloproteinase 2 (MMP2) and cathepsin D. price>

R-M-607 ACV trifluoroacetate salt ACV trifluoroacetate salt,CAS :32467-88-2 from ruixi.ACV is the key intermediate in the biosynthesis of all penicillin and cephalosporin antibiotics by eukaryotic and prokaryotic microorganisms. price>
R-M-666 Antistasin-Related Peptide Antistasin-Related Peptide,CAS :161561-46-2 from ruixi.Antistasin, isolated from the Mexican leech Hementeria officinalis, is a 119 amino acid protein which is a selective and potent inhibitor of coagulation factor Xa. (D-Arg³²)-Antistasin (32-38) is the shortest peptide displaying anticoagulant activity in human plasma. This peptide might be a model structure for the development of low molecular weight anticoagulants. price>
