Relaxin is a member of the insulin superfamily and has many biological actions including angiogenesis and collagen degradation. It is a 6 kDa peptide hormone consisting of two peptide chains (A and B) tethered by two disulphide bonds. Past structure-function relationship studies have shown the key receptor binding site of relaxin to be principally situated within the B-chain alpha-helix. Molecular dynamic simulations were performed to aid the design of conformationally constrained relaxin B-chain analogues that possess alpha-helical structure and relaxin-like activity. Restraints included disulphide bonds, both single and double, and lactam bonds. Each peptide was prepared by solid phase syn..
