Melittina

Descrizione:

Melittina è un peptide derivato dal veleno delle api (Apis mellifera) ed è noto per la sua potente attività biologica. È composto da 26 aminoacidi e ha un peso molecolare di circa 2846 Da. Melittina è caratterizzato dalla sua natura anfipatica, che gli consente di interagire con le membrane lipidiche, portando alla disruzione della membrana e alla lisi cellulare. Questa proprietà lo rende un argomento di interesse in vari campi, tra cui l'immunologia e la ricerca sul cancro, poiché mostra attività antimicrobiche e antitumorali. Inoltre, Melittina può indurre infiammazione ed è stato studiato per le sue potenziali applicazioni terapeutiche, sebbene i suoi effetti citotossici richiedano una considerazione attenta nell'uso medico. Il peptide è solubile in acqua e presenta una struttura elicoidale in ambienti di membrana, contribuendo alla sua capacità di formare pori nelle doppie membrane lipidiche. In generale, Melittina funge da modello prezioso per comprendere le interazioni peptide-membrana e ha potenziale per sviluppare nuovi agenti terapeutici.

Melittin

CAS: 20449-79-0

Synthetic melittin, the main component of the honeybee venom. The amphiphilic nature of this antimicrobial peptide makes it a excellent model compound for monitoring lipid-protein interactions in membranes. Adade et al. observed that melittin peptide could kill Trypanosoma cruzi parasites by inducing different cell death pathways.

Apitherapy (the use of honey bee products in alternative medicine) is an emerging field, with a long history of unsupported health benefits, particularly in cancer. Components of bee venom have been demonstrated to have antitumoral effects in various cancers. For example, honey bee venom (XM176021) was shown to reduce metastases of breast cancer to the lungs and inhibit tumour growth (Orsolić, et al., 2003). Similarly, the active component of bee venom, a peptide called melittin (FM10065), showed anticancer selectivity through undefined molecular mechanisms and suggests novel treatment strategies for aggressive breast cancers (Duffy, et al., 2020).

Melittin

CAS: 20449-79-0

Melittin is a 26-residue peptide originally isolated from venom of the European honeybee. Melittin is a cationic, hemolytic peptide from honey bee venom. Melittin lowers the surface tension at the plasma membrane and causes cell lysis. Melittin exhibits potent anti-inflammatory and antimicrobial activity. Melittin has been extensively used as a model peptide for observing membrane lipid-protein interactions.

Melittin

CAS: 20449-79-0

Melittin is a major component of bee venom that has been shown to have antibacterial efficacy against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus. It also demonstrates anti-viral activity, for example it inhibits human immunodeficiency virus and herpes simplex virus. Furthermore it can be used in the treatment of inflammatory-related illnesses due to it inhibiting the phospholipase A2 enzyme. In addition to this Melittin's abaility to inhibit inflammatory mediators such as nitric oxide and cyclooxygenase-2 aids in the treatment of inflammatory diseases. As a result of Melittin having the capabilities of attacking lipid membranes and it surpressing COX-2 mRNA expression it can also be used in the treatment of tumours. The bound form of melittin is not toxic to mammalian cells, but it is toxic when it is released into the cell cytoplasm. Melittin has been shown to inhibit transcriptional regulation and locomotor activity in mice. This may be due to its ability to bind DNA, preventing transcription and translation of certain genes. Lastly It has strong hemolytic activity and been seen to increase insulin secretion via depolarization of pancreatic beta-cells. Melittin is a diverse peptide which can be used ina whole spectrum of research and therapeutic areas.
