Title:
CYCLOSPORINE ANALOGUE MIXTURES AND THEIR USE AS IMMUNOMODULATING AGENTS
Document Type and Number:
Japanese Patent JP2013136597
Kind Code:
A
Abstract:

To provide cyclosporine analogues that posse enhanced efficacy and reduced toxicity compared with presently known cyclosporine.

There are provided cis and trans-isomers of cyclosporine A analogs referred to as ISATX247, and derivatives thereof. ISATX247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The stereoselective synthetic pathways utilize a Witting reaction or organometallic reagents including inorganic elements, such as boron, silicon, titanium, and lithium. The ratio of isomers in a mixture may range from about 10 to 90 wt.% of the (E)-isomer to about 90 to 10 wt.% of the (Z)-isomer, based on the total weight of the mixture.
