Bronchogen

Bronchogen is a synthetic tetrapeptide, H-Ala-Glu-Asp-Leu-OH (single-letter AEDL), of L-alanine, L-glutamic acid, L-aspartic acid and L-leucine — an Ala-Glu-Asp-X analogue of Epithalon (AEDG) from the St. Petersburg (Khavinson) line of short peptide bioregulators. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C18H30N4O9 and the values computed from it. No biological activity, mechanism, or use is described or implied.

Bronchogen has the sequence Ala-Glu-Asp-Leu. A linear tetrapeptide, H-Ala-Glu-Asp-Leu-OH (single-letter AEDL), with free termini; it shares the Ala-Glu-Asp core of Epithalon (AEDG), ending in L-leucine rather than glycine. Formula C18H30N4O9. Identity is reconciled against PubChem CID 11690869: the stereo-defined InChIKey OFZRHTIWKZWPQF-BJDJZHNGSA-N derived from the sequence matches the record pulled live from PubChem PUG-REST at build (molecular formula and full InChIKey), with no unassigned stereocentres. The draft had omitted the InChIKey pending this reconciliation; no CAS or UNII is asserted. A computed 3D conformer is held pending the chemist sign-off.

Bronchogen has the molecular formula C18H30N4O9, giving an average molecular weight of 446.45 g/mol and a computed monoisotopic mass of 446.2013 Da.

The CAS Registry Number for Bronchogen is —. Its PubChem CID is 11690869 and its InChIKey is OFZRHTIWKZWPQF-BJDJZHNGSA-N.

Yes. Bronchogen is a peptide — a chain of amino-acid residues joined by peptide bonds, 4 residues in length. Its identity is defined by that sequence and its molecular mass.

As a research material, Bronchogen is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.

No. Bronchogen is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.

No. Bronchogen is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
