dc.description.abstractThe emergence of cancer resistance to targeted therapy represents a significant challenge in cancer treatment. Therefore, identifying new anticancer candidates, particularly those addressing oncogenic mutants, is an urgent medical demand. A campaign of structural modifications has been conducted to further optimize our previously reported 2-anilinoquinoline-diarylamides conjugate VII as a B-RAFV600E/C-RAF inhibitor. Considering the incorporation of a methylene bridge between the terminal phenyl and cyclic diamine, focused quinoline-based arylamides have been tailored, synthesized, and biologically evaluated. Among them, the 5/6-hydroxyquinolines 17b and 18a stood out as the most potent members, with IC50 values of 0.128 ?M, 0.114 ?M against B-RAFV600E, and 0.0653 ?M, 0.0676 ?M against C-RAF. Most importantly, 17b elicited remarkable inhibitory potency against the clinically resistant B-RAFV600K mutant with an IC50 value of 0.0616 ?M. The putative binding mode of 17b and 18a were studied by molecular docking and molecular dynamics (MD). Moreover, the antiproliferative activity of all target compounds has been examined over a panel of NCI-60 human cancer cell lines. In agreement with cell-free assays, the designed compounds exerted superior anticancer impact over the lead quinoline VII against all cell lines at a 10 ?M dose. Notably, both 17b and 18b showed highly potent antiproliferative activity against melanoma cell lines with growth percent under ?90% (SK-MEL-29, SK-MEL-5, and UACC-62) at a single dose, while 17b maintained potency with GI50 values of 1.60?1.89 ?M against melanoma cell lines. Taken together, 17b, a promising B-RAFV600E/V600K and C-RAF kinase inhibitor, may serve as a valuable candidate in the arsenal of anticancer chemotherapeutics.-
