Thymosin Alpha-1 Mod – Research & Chemical Profile
Overview
Thymosin Alpha-1 (often abbreviated Tα1) is a naturally occurring thymic peptide involved in regulating the immune response. “Thymosin Alpha-1 Mod” refers to a modified or synthetic version of this 28-amino-acid peptide designed to enhance stability, absorption, or activity in research settings. It’s not an FDA-approved drug and is sold for laboratory and research purposes only.
Chemical Structure / Identifiers
- Sequence: H-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-OH (28 aa; modifications vary by supplier)
- Parent Peptide: Thymosin Alpha-1 (Tα1), originally isolated from thymus tissue
- Modifications: May include N-terminal acetylation, salt forms, or other stabilizing changes (not standardized across vendors)
- Registry/DB: Parent Tα1 is cataloged in PubChem as “thymalfasin”Primary Research Focus
- Immune Modulation: Preclinical and limited clinical data indicate Tα1 can enhance T-cell function, modulate cytokine production, and support host defense in viral or immunocompromised models.
- Anti-inflammatory Signaling: Evidence of balancing Th1/Th2 immune responses and reducing overactive inflammatory cascades.
- Adjuvant Potential: Studied as a vaccine adjuvant and in combination with standard therapies in infectious disease, oncology, and immune disorders.Research Context & Limitations
- Non-Standardized Modifications: “Tα1 Mod” isn’t a single chemical entity; purity, sequence confirmation, and biological activity can differ by source.
- Regulatory Status: Neither the original peptide nor modified analogues are approved by major regulators for prevention or treatment of disease; laboratory use only.
- Human Data: Some published trials exist for the original thymalfasin, but modified versions lack established dosing, pharmacokinetics, or safety profiles.Key Literature & References
