A group of new compounds, N-(all-trans-Retinoyl)-L-cysteic acid, N-(13-cis-Retinoyl)-L-cysteic acid, N-(all-trans-Retinoyl)-L-cysteinesulfinic acid, N-(13-cis-Retinoyl)-L-cysteinesulfinic acid, N-(all-trans-Retinoyl)-L-homocysteic acid, N-(13-cis-Retinoyl)-L-homocysteic acid, and sodium salts of these compounds, including sodium salts of their esters and amides, is shown to exhibit therapeutic effects per se, and which compounds in combination with cytotoxic compounds, such as docetaxel, paclitaxel, doxorubicin and mitoxantrone, exhibit a synergistic effect. These compounds make it possible to manufacture new formulations of poorly soluble pharmaceutical compounds, and the present invention discloses a process of manufacturing water-soluble formulations of such compounds, exemplified by docetaxel, and paclitaxel, exhibiting enhanced pharmacological activity, and formulations of water-soluble pharmaceuticals exemplified by doxorubicin and mitoxantrone, exhibiting improved therapeutic efficacy.
一组新化合物,N-(全反式视黄醛)-L-半胱氨酸酸,N-(13-顺式视黄醛)-L-半胱氨酸酸,N-(全反式视黄醛)-L-半胱氨酸亚磺酸,N-(13-顺式视黄醛)-L-半胱氨酸亚磺酸,N-(全反式视黄醛)-L-同型半胱氨酸,N-(13-顺式视黄醛)-L-同型半胱氨酸,以及这些化合物的钠盐,包括它们的酯和酰胺的钠盐,被证明本身具有治疗效果,并且这些化合物与细胞毒性化合物(如多西紫杉醇、紫杉醇、阿霉素和米托蒽醌)结合时表现出协同作用。这些化合物使得可以制造新的难溶性药物化合物的制剂,本发明揭示了一种制造这些化合物的水溶性制剂的过程,以多西紫杉醇和紫杉醇为例,表现出增强的药理活性,以阿霉素和米托蒽醌为例的水溶性药物制剂,表现出改善的治疗功效。
