摘要:
Compounds, ceramide analogues, having a cyclic structure derived from cyclopropane, cyclobutane or cyclopentane, the ring bearing two chains consisting of an amide function. Each amide function is attached to the ring by the nitrogen atom of the function and carries a hydrocarbon chain derived from a fatty acid. The amide functions can be cis or trans relative to one another. Processes for the preparation of these novel compounds as well as pharmaceutical and/or cosmetic compositions containing them.
