Polybia-MP1 CAS NO.872043-01-1
<p>Polybia-MP1 is a cationic amphipathic peptide derived from the venom of the Brazilian wasp <em>Polybia paulista</em>, belonging to the mastoparan family. It is widely recognized for its dual-functionality as a potent antimicrobial agent and a selective anticancer peptide. With its ability to preferentially target microbial and cancer cell membranes while displaying low cytotoxicity towards normal mammalian cells,…

1.MECHANISM OF ACTION
The peptide operates via a membrane-disruptive mechanism driven by electrostatic interactions. Its cationic nature allows it to bind selectively to anionic phospholipids, such as phosphatidylserine (PS) and phosphatidylethanolamine (PE), which are abnormally exposed on the outer leaflets of cancer cells and bacterial membranes. This binding induces the formation of toroidal pores, leading to rapid membrane permeabilization, ion leakage, and ultimately, cell lysis. The synergy between PS and PE significantly amplifies pore formation, underpinning its selective toxicity.
2.PRODUCT INDICATIONS
This product is indicated for preclinical research in oncology, microbiology, and drug discovery. It is utilized to study novel cancer therapies targeting prostate, bladder, and leukemic cells, as well as to combat multidrug-resistant bacterial and fungal infections. Researchers employ it in structural-activity relationship (SAR) studies to engineer analogs with enhanced selectivity, and in biophysical assays to investigate membrane-peptide interactions.
3.CLINICAL EFFICACY OF PRODUCT
Preclinical studies demonstrate that Polybia-MP1 exhibits potent cytotoxic activity against various cancer cell lines (e.g., IC50 ~11–37 µM for PC-3, Biu87) and broad-spectrum antimicrobial effects (MIC 4–32 µM). Importantly, it shows high selectivity by causing minimal hemolysis to healthy red blood cells, validating its potential as a safe and effective lead compound for targeted therapies against resistant pathogens and tumors.
