Peptides with Dual Antimicrobial and Anticancer Activities.

Area of Science:

• Biochemistry
• Immunology
• Pharmacology

Background:

• Rising incidence of cancer and multi-resistant infections poses significant global health challenges.
• Chronic infections and cancer treatments often lead to immune system instability and opportunistic infections.
• There is an urgent need for novel therapeutic strategies with improved efficacy and reduced side effects.

Purpose of the Study:

• To review the characteristics of antimicrobial peptides (AMPs) with dual antimicrobial and anticancer activities (ACPs).
• To explore the potential of AMPs as a novel therapeutic approach for both infections and cancer.
• To discuss AMPs currently in clinical trials for these dual applications.

Main Methods:

• Literature review of scientific publications on AMPs and their dual activities.
• Analysis of peptide properties, including cationic and amphipathic characteristics.
• Examination of proposed mechanisms of action, including membrane-level and intracellular targets.

Main Results:

• Certain AMPs exhibit potent activity against both microbial pathogens and cancer cells.
• These dual-acting peptides offer a promising alternative to conventional treatments, with a lower propensity for resistance development.
• Mechanisms of action involve disruption of microbial membranes and interference with intracellular cancer targets.

Conclusions:

• AMPs with dual antimicrobial and anticancer functions represent a significant advancement in therapeutic development.
• Their unique properties and mechanisms offer a potential solution to combatting both infections and cancer.
• Further research and clinical trials are warranted to fully realize the therapeutic potential of these peptides.
