This disclosure provides compounds with Bcl inhibitory activity based on a new chemical scaffold, as shown in Formula (I):
Phosphonamidate compounds disclosed herein typically include a P-phenyl phosphonamidate moiety which is substituted with an N-aryl or N-heteroaryl group. The P-phenyl phosphonamidate moiety may be optionally substituted at phosphorus with thio (═S) instead of oxo (═O), and/or with a thioxy group or a second amino group instead of an oxy group. One of the heteroatoms attached to phosphorus may be cyclically linked to the N-substituted nitrogen atom that is attached to the phosphorus to provide a heterocyclic ring. By incorporating such a cyclic constraint between two phosphorus substituents of the core linking moiety, a favorable binding conformation may 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:
本文公开的膦酰胺化合物通常包括一个被 N-芳基或 N-杂芳基取代的 P-苯基膦酰胺分子。P-苯基膦甲酰胺基团可任选被硫代(═S)取代氧代(═O),和/或被硫氧基团或第二氨基取代氧基团。与磷相连的杂原子之一可与与磷相连的 N-取代的氮原子环状连接,形成杂环。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,可促进化合物形成有利的结合构象。所选化合物可促进衰老细胞的凋亡,并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。
