An ester of ArOH according to the formula R—X—CO—OAr, wherein ArOH is a pharmaceutically active compound selected from the group consisting of SN-38, PI-103, etoposide and fenretinide, wherein a) R is a residue of cholesterol, sitosterol, SN-38, PI-103, etoposide or fenretinide and X is O—CO-L, wherein L is either a direct bond or a linking group including a branched or unbranched hydrocarbyl moiety that may optionally include in-chain or pendant heteroatom substituents and/or cyclic moieties; b) R—X—CO-0 is an all-trans retinoate radical or the 9-cis or 13-cis isomer thereof; or c) R—X— is a branched or unbranched, saturated or unsaturated hydrocarbyl moiety comprising at least 5 carbon atoms and optionally including at least one in-chain or pendant heteroatom substituent and/or cyclic moiety. A dispersion of nanoparticles in an aqueous medium includes nanoparticles including an ester of ArOH according to the formula R—X—CO—OAr wherein ArOH is a pharmaceutically active compound in which Ar is a substituted or unsubstituted aryl or heteroaryl radical, and wherein R is as defined above or R—X—CO-0 is as defined above. The ester or dispersion may be used to treat a diagnosed medical condition in a patient.
根据公式R-X-CO-OAr,其中ArOH是从SN-38、PI-103、依托泊苷和芬雷替尼等药物活性化合物中选择的酯。其中a)R是胆固醇、谷甾醇、SN-38、PI-103、依托泊苷或芬雷替尼的残基,X是O-CO-L,其中L是直接键或包括支链或非支链的碳氢基团,可选择包括链内或链外的杂原子取代基和/或环状基团。b)R-X-CO-O是全反式维甲酸基团或其9-顺反或13-顺反异构体;或c)R-X-是支链或非支链、饱和或不饱和的碳氢基团,至少包含5个碳原子,可选择包括至少一个链内或链外的杂原子取代基和/或环状基团。水介质中的纳米颗粒分散体包括纳米颗粒,其中包括公式R-X-CO-OAr的ArOH酯,其中Ar是取代或未取代的芳基或杂芳基基团,R如上所定义或R-X-CO-O如上所定义。该酯或分散体可用于治疗患者的已诊断医疗状况。
