Snake venom meets oncology: unraveling the anticancer potential of crotamine

Area of Science:

• Biochemistry
• Pharmacology
• Toxicology

Background:

• Cancer presents a major global health burden, necessitating innovative treatments.
• Crotamine, a peptide from Crotalus durissus spp. venom, exhibits anticancer properties.
• Current cancer therapies face limitations, driving research into novel agents.

Purpose of the Study:

• To review the structural and functional aspects of crotamine for anticancer applications.
• To explore crotamine's mechanisms of action in targeting tumor cells.
• To assess crotamine's potential for enhancing cancer drug delivery and efficacy.

Main Methods:

• Review of existing literature on crotamine's biological activities.
• Analysis of crotamine's interaction with ionic channels and cellular uptake.
• Examination of preclinical in vitro and in vivo studies on tumor models.

Main Results:

• Crotamine exhibits selective cytotoxicity against tumor cells.
• Mechanisms include calcium influx, Kv channel inhibition, and cell-penetrating peptide activity.
• Preclinical data show inhibition of tumor growth with low toxicity and immunogenicity.
• Crotamine facilitates intracellular delivery of co-administered drugs.

Conclusions:

• Crotamine demonstrates significant potential as an anticancer therapeutic agent.
• Its unique properties support its development for cancer treatment.
• Further research is needed to clarify molecular targets and support clinical translation.
