Thymostimulin (TP-1)

In a double-blind, placebo-controlled trial in 29 patients with severe atopic eczema, ten weeks of thymostimulin improved clinical scores at three months, but the difference did not last and immunological measures did not change.

Summary

In a double-blind, placebo-controlled trial in 29 patients with severe atopic eczema, ten weeks of thymostimulin improved clinical scores at three months, but the difference did not last and immunological measures did not change. · pmid:1835403

Classification

Thymostimulin (TP-1) is a polypeptide extract of thymus. · pmid:1835403

Mechanism

In mice with Lewis lung carcinoma, thymostimulin delayed the primary tumour and, after the tumour was removed or together with chemotherapy, increased survival and the share of mice that stayed tumour-free for six months. · pmid:7248976

Identity

No public registry record is shown for this page: PubChem gave no record that proves it is this substance.

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 Thymostimulin (TP-1) 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.
