Thymosin alpha-1
An immune-modulating peptide (Zadaxin) approved in many countries for hepatitis and as a vaccine adjuvant; not FDA-approved.
Key facts
- Also known as: Zadaxin, thymalfasin
- Status: Approved
- Used for: Immune support
- Natural counterpart: A naturally occurring thymic peptide (from prothymosin α).
- Target enzyme / receptor: Toll-like receptors (TLR2/TLR9) on immune cells
- Signalling pathway: Enhances dendritic-cell & T-cell maturation → stronger cell-mediated immunity
In plain terms: Wakes up immune cells (T-cells, dendritic cells) to fight infection. - Crystal structure: no peptide–target complex in the PDB yet — study the target ↗
