This disclosure provides compounds with Bcl inhibitory activity based on a new chemical scaffold, as shown in Formula (I).
The phospholidine compounds can include a P-phenyl phospholidine moiety which is substituted with an N-aryl or N-heteroaryl group. The P-phenyl phospholidine moiety can be optionally substituted at phosphorus with thio (═S) instead of oxo (═O). A second heteroatom attached to phosphorus can be cyclically linked to the N-substituted nitrogen atom of the phospholidine that is attached to the phosphorus to provide, together with the phosphorus atom through which they are connected, a heterocyclic ring. By incorporating such a cyclic constraint between two phosphorus substituents of the core linking moiety a favorable binding conformation can be promoted in the compounds. Selected compounds promote apoptosis in senescent cells, and can be developed for treating senescent-related conditions, such as osteoarthritis, ophthalmic disease, pulmonary disease, and atherosclerosis. Selected compounds promote apoptosis in cancer cells, and can be developed as chemotherapeutic agents.
本公开提供了基于新化学支架的具有 Bcl 抑制活性的化合物,如式 (I) 所示。
膦啶化合物可以包括一个被 N-芳基或 N-杂芳基取代的 P-苯基膦啶分子。P-苯基膦烷分子可以任选被硫代(═S)而不是氧代(═O)取代。连接到磷上的第二个杂原子可以与连接到磷上的磷苷的 N-取代的氮原子循环连接,从而与通过它们连接的磷原子一起形成一个杂环。通过在核心连接分子的两个磷取代基之间加入这种环状约束,可以促进化合物形成有利的结合构象。所选化合物能促进衰老细胞的凋亡,可开发用于治疗与衰老有关的疾病,如骨关节炎、眼科疾病、肺部疾病和动脉粥样硬化。精选化合物能促进癌细胞凋亡,可开发为化疗药物。
