Title: Synthesis of derivatives of the novel cyclophilin-binding immunosuppressant sanglifehrin A with reduced numbers of polar functions.
Authors: Bänteli R, Wagner J, Zenke G.
Abstract: The syntheses and the biological activities of 53-deoxo sanglifehrin A (2) and 61-deoxy octahydrosanglifehrin A (3) are described. Compound 2 shows intracellular cyclophilin (CyP)-binding and immunosuppressive activity in the mixed-lymphocyte reaction (MLR) similar to that of sanglifehrin A (1). Compound 3 is much less active in the MLR despite unchanged intracellular CyP-binding. This indicates that the 53-keto group is not necessary for immunosuppressive activity, while the 61 hydroxy group is required.
