This class groups short synthetic peptides studied in cellular-senescence and telomere-biology models. Two distinct research threads are represented: telomere/telomerase regulation, where the tetrapeptide Epithalon has been examined in cultured human fibroblasts and other cell lines for effects on hTERT expression, telomerase activity and telomere length; and senolysis, where the cell-penetrating peptide FOXO4-DRI has been used to disrupt the FOXO4-p53 interaction and induce apoptosis selectively in senescent cells in vitro and in mouse models. The literature is predominantly preclinical (cell culture and rodent), with a substantial fraction of the Epithalon work originating from a single research group, and includes at least one animal study reporting adverse hemodynamic effects of senescent-cell clearance. These compounds are supplied for laboratory research only; no clinical conclusions are supported by the studies cited in the Research Library.
Liv Pure supplies Epithalon and FOXO4-DRI as lyophilized research reagents; each listing shows the quantities available and links to its certificate of analysis where a lot has been tested. The published in-vitro and preclinical literature for every compound in this class, with PubMed links, is collected in the Senolytic & Telomere Peptides section of the Research Library. All products are for in-vitro laboratory research only and are not for human or animal use.


Liv Pure supplies research-grade synthetic peptides and laboratory reagents to qualified researchers and institutions. Every lot ships with a lot-specific certificate of analysis.
