In order to expand the structural diversity of Bcr-Abl inhibitors, twenty hybrids (series E and P) have been synthesized and characterized based on Imatinib and GNF-2. Their biological activities were evaluated in vitro against human leukemia cells. Most compounds exhibited potent antiproliferative activity against K562 cells, especially for compounds E4, E5 and E7. Furthermore, these new hybrids were also screened for Abl kinase inhibitory activity, and some of them inhibited Abl kinase with low micromolar IC50 values. In particular, compound P3 displayed the most potent activity with IC50 value of 0.017 μM comparable with that of Imatinib. Molecular docking studies indicated that these novel hybrids fitted well with the active site of Bcr-Abl. These results suggested the great potential of these compounds as novel Bcr-Abl inhibitors.

As a continuation to our previous research, twenty-eight aromatic-heterocyclic biphenyls were designed and synthesized as novel Bcr-Abl inhibitors. The title compounds were investigated for their antiproliferative activities against wild K562 cells and Imatinib-resistant K562 cells (K562R). The results indicated that most of them exhibited potent Bcr-Abl inhibition and moderate antiproliferative potency against K562 cells. Furthermore, three compounds 3, 7 and 21 displayed moderate antiproliferative activities against K562R cells. Molecular docking indicated that 3 bound more tightly with Bcr-AblT315I compared to Bcr-AblWT. The higher affinity was consistent with its relatively promising K562R cell growth inhibition. These aromatic-heterocyclic biphenyls could be considered as novel lead compound for optimized as Bcr-AblT315I inhibitors. They provide a good starting point for the further development of novel anti-leukemia agents capable of dealing with clinical acquired resistance against Imatinib.

Figure Presented. An imidazole-catalyzed protocol for monoacylation of symmetrical diamines has been developed. The protocol gave selective monoacylation of aliphatic (cyclic and acyclic) primary and secondary diamines. In the reaction, imidazole acts as both catalyst and a leaving group. Different monoacylated piperazines and other diamines were synthesized at room temperature in an ethanol/water solvent system.
