In recent years, antimicrobial peptides (AMPs) have emerged as potent agents with potential applications ranging from therapeutics to diagnostics. Research into their synthesis and their integration into peptide drug conjugates promises to revolutionize modern medicine, offering new solutions in the face of rising antibiotic resistance. This article delves into AMPs, the methods employed in their synthesis, and their role in peptide drug conjugates.

Antimicrobial peptides are short sequences of amino acids that have the intrinsic ability to neutralize pathogens, including bacteria, fungi, and viruses. Found in virtually all life forms, AMPs play a crucial role in the innate immune response, providing a first line of defense against infections. Their diverse mechanisms of action, ability to target a broad spectrum of microbes, and low likelihood of inducing resistance make them attractive candidates for therapeutic development.

Mechanisms of Action

AMPs can effectively disrupt microbial cells through various mechanisms:

Membrane Disruption: Many AMPs interact with microbial membranes, leading to pore formation, membrane disintegration, and cell lysis.

Intracellular Targeting: Some AMPs penetrate microbial cells and interfere with intracellular targets, such as nucleic acids and proteins, disrupting essential biological processes.

Immune Modulation: Beyond direct antimicrobial activity, AMPs can modulate the host’s immune response, enhancing the ability to combat infections.
