Thymogen (Glu-Trp, EW) — living evidence map

The Atlas page holds the claims; this is how its evidence evolved.

Classification

Thymogen is the dipeptide L-Glu-L-Trp, an immunostimulant; its enantiomer D-Glu(D-Trp), thymodepressin, acts as an immunosuppressor, one of the first examples of opposite effects from two enantiomeric peptide drugs. · pmid:38732260

Mechanism

In an in vitro model of inflammation, alpha-glutamyl-tryptophan reduced TNF-alpha-induced IL-1-alpha production in endothelial cells and IL-8 secretion in blood mononuclear cells. · pmid:37131521

Identity

PubChem CID 100094: Thymogen, C16H19N3O5, 333.34 g/mol. · pubchem:100094

CAS registry number 38101-59-6, 122933-59-9. · pubchem:100094

IUPAC name: (4S)-4-amino-5-[[(1S)-1-carboxy-2-(1H-indol-3-yl)ethyl]amino]-5-oxopentanoic acid. · pubchem:100094

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Thymogen (Glu-Trp, EW) yet.

Dose evidence, rung by rung

No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.

  1. Approved-label dose · a resolved regulatory document names a labelled dose

    nothing resolved on this rung

  2. Studied human doses · resolved human studies at the established tier

    nothing resolved on this rung

  3. Observational evidence · resolved human data at the emerging tier: thin, or contested

    nothing resolved on this rung

  4. Community-reported protocols · protocol propositions from distinct members, counted once per human

    nothing resolved on this rung

  5. Preclinical evidence · resolved animal, cell or mechanistic work
