Nonathymulin

Summary

Nonathymulin (also called Zn-thymulin analog or ZnT) is a synthetic nonapeptide analog of thymulin, a naturally occurring thymic hormone. It retains the zinc-binding and immunomodulatory properties of the native peptide. Research has explored its roles in immune reconstitution, neuroprotection, hair follicle cycling, and anti-inflammatory activity. It is not approved for clinical use and remains an investigational/research compound.

Mechanism of Action

Synthetic analog of facteur thymique sérique (FTS/thymulin); binds zinc to form the biologically active zinc-thymulin complex; modulates T-cell differentiation and maturation, promotes T-lymphocyte functional activity, and exhibits anti-inflammatory and neuroprotective effects via modulation of cytokine production and HPA axis interactions
