DescriptionECHEMI Editorial ReferenceThymalfasin is an immunomodulating agent able to enhance the Thl immune response. Sequence: N-acetyl-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.
Thymalfasin is a polypeptide.|Thymalfasin is a synthetic analogue of thymosin-alpha-1, a 28-amino acid protein derived from the precursor protein prothymosin-alpha. Exhibiting a variety of immunoregulating properties, thymosin-alpha-1 induces differentiation of murine T-cell precursors and human thymocytes and the terminal differentiation of functionally immature cord blood lymphocytes and induces production of IL-2, high affinity IL-2 receptors, and B-cell growth factors by peripheral blood mononuclear cells. T-helper and cytotoxic/suppressor T-cell populations are targets of thymosin activity. Thymosin-alpha-1 has been shown to increase the efficiency of antigen presentation by macrophages and to be an endogenous modulator of alpha-thrombin activity. (NCI04)|A thymus hormone polypeptide found in thymosin fraction 5 (a crude thymus gland extract) but now produced by synthesis. It is used alone or with interferon as an immunomodulator for the treatment of CHRONIC HEPATITIS B and HEPATITIS C. Thymalfasin is also used for the treatment of chemotherapy-induced immunosuppression, and to enhance the efficacy of influenza and hepatitis B vaccines in immunocompromised patients.CertificatesBasic Info-

Class:
GLP-1R agonist
Status:FDA-approved (Ozempic / Wegovy / Rybelsus)
Mechanism:Long-acting, selective glucagon-like peptide-1 (GLP-1) receptor agonist with 94% sequence homology to human GLP-1. Engineered for extended half-life (~1 week) via albumin binding (fatty acid acylation at Lys26) and resistance to DPP-4 degradation (Aib substitution at position 8). Promotes insulin secretion, inhibits glucagon release, delays gastric emptying, and reduces appetite via central nervous system GLP-1R activation.
Activity note:Potent, selective GLP-1R agonist. Reported binding affinity Ki = 0.38 ± 0.06 nM. Semaglutide is a human GLP-1 analog with structural modifications for albumin binding (C18 fatty diacid at Lys26) and enzymatic stability (Aib8 substitution).
