Cyclosporin A is effective in the treatment of asthma patients, but its chronic use is limited by toxicity. Novel cyclosporin A analogues were synthesized utilizing the olefin metathesis reaction and evaluated in a calcineurin A inhibition assay. The novel analogues demonstrated activity comparable to activity of the parent molecule and are potential soft drugs.
