Mechanism & Target Class
This blend combines four structurally and mechanistically distinct molecules. Cartalax (Ala-Glu-Asp; AED) belongs to the class of ultrashort peptide bioregulators studied for proposed nuclear-entry and interaction with histone proteins and DNA promoter sequences, with downstream changes in structural matrix protein transcription examined in cell-culture models. BPC-157 is a 15-residue synthetic peptide whose primary literature maps to the nitric oxide (NO) system and VEGFR2-associated pathways — specifically the VEGFR2–Akt–eNOS and Src–Caveolin-1–eNOS axes — as well as growth-hormone-receptor-linked transcriptional readouts in fibroblast models. TB-500, characterized in the indexed literature as an N-terminally acetylated heptapeptide (Ac-LKKTETQ) corresponding to an actin-binding region within a larger endogenous peptide, is studied in the context of G-actin sequestration and cytoskeletal dynamics; this short sequence and the full-length precursor are not established as equivalent and findings from each are attributed separately. KPV (Lys-Pro-Val) is studied primarily through PepT1 (SLC15A1)-mediated intestinal uptake and downstream NF-κB and MAPK pathway engagement in epithelial and immune cell models. The blend has no single shared molecular target; each component is associated with distinct receptor contexts and signaling programs.
Storage & Handling
- Lyophilized
- -20°C for long-term preservation; protect from light and moisture.
- Handling
- Multi-peptide formulation; individual component stabilities vary; avoid excessive physical agitation post-reconstitution.
