Imatinib (IMT) is the first-in-class BCR-ABL commercial tyrosine kinase inhibitor (TKI). However, the resistance and toxicity associated with the use of IMT highlight the importance of the search for new TKIs. In this context, heterocyclic systems, such as quinoline, which is present as a pharmacophore in the structure of the TKI inhibitor bosutinib (BST), have been widely applied. Thus, this work aimed to obtain new hybrids of imatinib containing quinoline moieties and evaluate them against K562 cells. The compounds were synthesized with a high purity degree. Among the produced molecules, the inhibitor 4-methyl-N3-(4-(pyridin-3-yl)pyrimidin-2-yl)-N1-(quinolin-4-yl)benzene-1,3-diamine (2g) showed a suitable reduction in cell viability, with a CC50 value of 0.9 μM (IMT, CC50 = 0.08 μM). Molecular docking results suggest that the interaction between the most active inhibitor 2g and the BCR-ABL1 enzyme occurs at the bosutinib binding site through a competitive inhibition mechanism. Despite being less potent and selective than IMT, 2g is a suitable prototype for use in the search for new drugs against chronic myeloid leukemia (CML), especially in patients with acquired resistance to IMT.

A copper-catalyzed three-component synthetic method has been developed for the synthesis of substituted 4-quinolone derivatives from substituted 3-(2-halophenyl)-3-oxopropane, aldehydes and aq. NH3 using water as an environmentally benign reaction media. Moreover, the synthetic utility of the obtained products has been successfully applied for the synthesis of available oxolinic acid and BQCA drugs. The key features of this approach include commercially available starting materials, broad scope, and moderate to good reaction yields. Reaction with formaldehyde, and other functionalities such as ?CN, ?NO2, ?SO2Ar, and ?COAr were also successful. In addition, reaction with heterocyclic compounds such as 3-(3-bromothiophen-2-yl)-3-oxopropanenitrile proceeded smoothly to afford tetrahydrothieno[3,2-b]pyridine-6-carbonitrile analogues. The practicality of the designed protocol was confirmed by gram scale synthesis of two derivatives. (Figure presented.).
