Research Overview

Pidotimod

Pidotimod has human data in recurrent infections, especially where immune stimulation or reduced infection frequency is the target. Published work commonly reports improvements in phagocyte function, mucosal defense, and fewer respiratory infection episodes.

Indolicidin

Indolicidin has been extensively studied as a prototype antimicrobial peptide with activity against bacteria, fungi, and some viruses. Research has also explored its use in anti-biofilm strategies and as a template for next-generation synthetic antimicrobial peptides.
