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。
