Background:

Cyclosporin A-Derivative 1 (Free base) is a crystalline intermediate derived from the opening of cyclosporin A extracted from patent WO 2013167703 A1. Cyclosporin A is an immunosuppressive agent which can bind to the cyclophilin and inhibit calcineurin.

Cyclosporin A-Derivative 1 is a non-immunosuppressive Cyclosporine A derivative. The cyclosporin is acylated on the butenyl-methyl-threonine side chain and then subjected to a ring-opening reaction (the ring opens between the sarcosine and the N-methyl-leucine residues). Cyclosporin A-Derivative 1 is a linear peptide intermediate[1].
