We offer peptides for sale as Peptides B7-33 6 mg. B7-33 is a single-chain peptide analog derived from the B-chain of human relaxin, supplied at 6 mg by Peptide Sciences. It is studied as a functionally selective agonist at the RXFP1 receptor, the relaxin receptor, and it is not the full two-chain relaxin hormone. That difference in structure is the reason the peptide is researched separately from relaxin itself, and the simplification is the point: a smaller molecule that keeps the receptor-facing surface.
From the relaxin B-chain
Relaxin is a two-chain hormone, and its B-chain carries much of the receptor-facing structure. B7-33 takes that portion and presents it as a single chain, which simplifies the molecule while retaining receptor activity. The result binds RXFP1 and engages signaling pathways that include ERK-associated cascades, but the response is described as biased rather than identical to the parent hormone. Biased signaling means some downstream routes are favored over others.
Fibrosis research
Preclinical work has examined fibroblast responses, extracellular matrix regulation and fibrosis models in the heart, lung and kidney. Heart, lung and kidney models each measure different endpoints, and a reduction in one does not automatically generalize to another. Those experiments are the basis for interest in the peptide. They do not establish that a commercial B7-33 product treats human fibrosis, and they do not transfer the clinical results of a different relaxin formulation to this molecule.
