FK866-NAMPT complex (PDB code: 2GVJ) with replacing the boron atom type by the C3 atom type of carboranes predicted that the NAMPT inhibitory activity of 2c was improved by the hydrogen bond formation between the carborane amide and H191 of NAMPT. Although dicarborane compounds 38, 50, 51, and 55 were synthesize aiming to two hydrophobic pockets present in the binding pocket of NAMPT, their inhibitory activity
根据化合物1的结构设计和合成了一系列含碳硼烷的NAMPT抑制剂,并使用NAMPT比色分析评估了NAMPT的抑制活性。在合成的化合物中,化合物2b和2c表现出显着的NAMPT抑制活性,IC50值分别为0.098±0.008和0.057±0.001 µM。使用FK866-NAMPT配合物(PDB代码:2GVJ)的晶体结构将化合物2与NAMPT的对接模拟,用硼烷的C3原子类型代替硼原子类型,这预示着氢键改善了2c的NAMPT抑制活性在碳硼烷酰胺和NAMPT的H191之间形成。尽管合成了二碳硼烷化合物38、50、51和55,目的是针对NAMPT结合口袋中存在的两个疏水口袋,
