Research Overview
LRAP
LRAP is one of the better-known amelogenin-derived peptides in regenerative dentistry because it can influence mineralization-related cell behavior. It remains a research peptide, but it is highly relevant to enamel repair and tooth-tissue engineering.
Piscidin-3
Preclinical research indicates strong activity against bacterial membranes and drug-resistant strains. Analogs are being evaluated to balance potency with lower toxicity and better stability.
