Aurora kinases play critical roles in the regulation of the cell cycle and mitotic spindle assembly. Aurora A kinase, a member of the Aurora protein family, is frequently highly expressed in tumors, and selective Aurora A inhibition serves as a significant component of anticancer therapy. However, designing highly selective Aurora A inhibitors is difficult because Aurora A and B share high homology and differ only by three residues in their ATP-binding pockets. Through structure-based drug design, we designed and synthesized a series of novel quinazolin-4-amine derivatives. These derivatives act as selective Aurora A kinase inhibitors by exploiting the structural differences between Aurora A and B. The selectivities of most compounds were improved (the best up to >757-fold) when comparing with the lead compound (3-fold). In vitro biochemical and cellular assays revealed that compound 6 potently inhibited Aurora A kinase and most human tumor cells. Furthermore, compound 6 effectively suppressed carcinoma, such as triple-negative breast cancers (TNBC) in an animal model. Therefore, compound 6 might serve as a promising anticancer drug. Moreover, through molecular dynamic (MD) analysis, we have identified that a salt bridge formed in Aurora B is key contributor for the isoform selectivity of the inhibitor. This salt bridge has not been previously detected in the reported crystal structure of Aurora B. These results might provide a crucial basis for the further development of highly potent inhibitors with high selectivity for Aurora A.

A highly efficient, easily recoverable and reusable Fe3O 4 magnetic nanoparticle-supported Cu(I) catalyst has been developed for the synthesis of quinazolinones and bicyclic pyrimidinones. In the presence of supported Cu(I) catalyst (10 mol%), amidines reacted with substituted 2-halobenzoic acids and 2-bromocycloalk-1-enecarboxylic acids to generate the corresponding N-heterocycle products in good to excellent yields at room temperature in DMF. In addition, the supported Cu(I) catalyst could be recovered at least 10 times without significant loss of its catalytic activity. Copyright
