Research Overview
Thymopentin
Thymopentin has a long history of preclinical and clinical investigation as a thymic peptide immunomodulator. Published studies report effects on T-cell subsets, cytokine responses, and immune recovery in recurrent infection settings.
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.
