The aim of the presented research was to explore anticancer potential of eleven newly synthesized tetrahydropyrimidine derivatives. The compounds were synthesized via Biginelli multicomponent one-pot reaction using different derivatives of vanillin, ethyl 4-chloroacetoacetate and (N-methyl)urea. The cytotoxic effects of the compounds were examined on three human malignant cell lines (HeLa, K562, and MCF7), and normal lung fibroblasts MRC-5. The mechanisms of anticancer activity were examined for two compounds 4a and 4b which showed the strongest and selective cytotoxicity against chronic myelogenous leukaemia K562 cells (IC50 = 1.76 ± 0.09, and 1.66 ± 0.05, respectively). The changes of matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 9 (MMP9), and vascular endothelial growth factor A (VEGFA) were investigated in the K562 cell line, as well as oncomiRNA miR-10b, miR-23a described to have both features, depending on a specific type of malignancy, and miR-34a with mostly described as a tumour suppressor.
