[3H]-Cyclosporin A labeled at the first amino acid ([ω-3H-MeBmt1]CS) has been prepared by tritium gas hydrogenolysis of [O-acetyl-ω-bromo- MeBmt1]CS followed by deprotection with methanolic sodium methoxide. The requisite bromo intermediate was prepared by bromination of [O-acetyl- MeBmt1]CS with N-bromosuccinimide. After synthesis and purification, 2.45 m8 of [ω-3H-MeBmt1]CS with a total activity of 327 MBq were produced with a radiochemical purity >97%, and specific activity of 160 GBq/mmol (4.3 Ci/mmol).

A practical and robust process for the derivatization of Cyclosporin A was demonstrated. The processes rely on the opening of Cyclosporin A and removal of amino acid fragments via Edman degradation, with the isolation of crystalline tetrafluoroboric salts of the corresponding acyclic polypeptides.

An albumin-binding CsA analogue 4MCsA was achieved by attachment of a thiol-reactive maleimide group at the side-chain of P4 position of CsA derivative. 4MCsA was semi-synthesized from CsA, and the cell-impermeability of albumin-4MCsA was detected by mass spectrometry and a competitive flow cytometry. 4MCsA exhibits inhibition of chemotaxis activity and inflammation by targeting extracellular CypA without immunosuppressive effect and cellular toxicity. These combined results suggested that 4MCsA can be restricted extracellularly through covalently binding to Cys34 of albumin with its maleimide group, and regulate the functions of cyclophilin A extracellularly.
