Summary

P-113D is a D‑amino‑acid analog of the histatin‑derived peptide P‑113, investigated for antifungal and antibacterial activity, particularly against oral Candida and drug‑resistant bacteria.

Mechanism of Action

Membrane disruption and intracellular targeting of microbes; D‑amino acid substitution enhances protease resistance and broadens antimicrobial spectrum.
