Chonluten — 20mg | EDG Khavinson Bronchial Peptide

Chonluten is a short-chain peptide bioregulator developed by the Khavinson group at the St. Petersburg Institute of Bioregulation and Gerontology in Russia. Belonging to the same “Khavinson bioregulator” class as Epithalon, Cortagen, and Pinealon, Chonluten is the tripeptide identified by Khavinson and colleagues as the bronchial / respiratory epithelium peptide bioregulator. The compound consists of the sequence Glu-Asp-Gly (EDG) and is proposed to function through tissue-specific gene expression modulation in respiratory epithelial cell populations. Chonluten has been investigated in the Russian academic literature (Bulletin of Experimental Biology and Medicine; Khavinson, Chalisova, and colleagues) for pulmonary cell biology, bronchial epithelium gene expression, and age-associated respiratory tract function in preclinical research models. Like other Khavinson bioregulators, Chonluten is studied primarily as a research tool for tissue-specific short-peptide pharmacology rather than as a defined receptor agonist.
