Method for the synthesis of the sodium salts of retinoyl derivatives

摘要

This invention relates to the synthesis of sodium salts of retinoyls derivatives, capable of potentiating the efficacy of therapeutically active compounds, for example cytotoxic compounds used in the treatment of cancer. These compounds have been shown to increase the pharmacological activity of a conventional paclitaxel formulation and to make it possible to manufacture a new formulation of paclitaxel, exhibiting improved solubility, improved storage properties, and increased therapeutic efficacy as shown in the enclosed examples.
