MODIFIED RETINOID COMPOUNDS AND THEIR USES

摘要

A method of minimizing or reducing the toxicity of a retinoid having a free carboxyl group and the resulting modified retinoids are described. The metho d comprises the step of esterifying the carboxyl group of the retinoid with a highly sterically hindered compound, which is preferably a secondary or tertiary alcohol. The resulting retinoid esters are rendered much less toxic than the starting or parent retinoid. This process provides a retinoid ester analog of reduced toxicity so that it may be administered orally with minima l side effects and with a much greater therapeutic window. The modified retino id compounds are useful in the treatment and prophylaxis of all diseases and disorders where retinoid compounds have been shown effective.
