A pro-apoptotic solid dispersion comprises, in essentially non-crystalline form, a Bcl-2 family protein inhibitory compound of Formula I as defined herein, dispersed in a solid matrix that comprises (a) a pharmaceutically acceptable water-soluble polymeric carrier and (b) a pharmaceutically acceptable surfactant. A process for preparing such a solid dispersion comprises dissolving the compound, the polymeric carrier and the surfactant in a suitable solvent, and removing the solvent to provide a solid matrix comprising the polymeric carrier and the surfactant and having the compound dispersed in essentially non-crystalline form therein. The solid dispersion is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.

α‐Alkylidene cyclic carbonates (αCCs) recently emerged as attractive CO2‐sourced synthons for the construction of complex organic molecules. Herein, we report the transformation of αCCs into novel families of sulfur‐containingcompounds by organocatalyzed chemoselective addition of thiols, following a domino process that is switched on/off depending on the desired product. The process is extremely

Three cysteine derivatives were synthesized in high yield by ligating monomethoxy oligo(ethylene glycol) (OEG) to l-cysteine thiol group using sulfenyl chlorides. These OEG groups containing di-, tri-, and tetra-EG units were linked with l-cysteine via disulfide bond. The three monomers were then converted into corresponding N-carboxyanhydrides (NCAs) using triphosgene in THF. Subsequent ring-opening
通过使用亚磺酰氯将单甲氧基低聚(乙二醇)(OEG)连接至1-半胱氨酸硫醇基团,高产率地合成了三种半胱氨酸衍生物。这些包含二-,三-和四-EG单元的OEG基团通过二硫键与1-半胱氨酸连接。然后使用三光气在THF中将这三种单体转化为相应的N-羧基酸酐(NCA)。随后,含有NCA的二硫键的开环聚合(ROP)给出了三种聚-EG x - 1-半胱氨酸衍生物。将所得到的聚EG X -升-半胱氨酸与X= 3和4在水中显示出热响应行为,但是令人惊讶地发现,温度诱导的相变是不可逆的。这种不可逆的热响应行为归因于二硫键交换引起的交联。使用PEG-NH 2作为大分子引发剂,我们还制备了两种PEG- b -聚-EG X -升-半胱氨酸二嵌段,这可能会经历不可逆的热诱导的溶胶-凝胶转变,这是由二硫键交换反应引起的。这些水凝胶显示出部分剪切稀化和快速恢复的特性,从而在生物医学应用中具有构建刺激反应性可注射水凝胶的新功能。
