A 26-amino-acid single-chain analog of the B-chain of human relaxin-2 (CAS 1818415-56-3) engineered to retain full RXFP1 receptor binding while exhibiting biased signaling toward pERK over the canonical cAMP pathway. Reproduces relaxin-2's antifibrotic and vasodilatory effects in preclinical cardiac, renal, and lung fibrosis models without its tumorigenic cAMP-driven activity. Not FDA-approved.
