ABSTRACT
Four benzophenones, three dihydrocoumarins, and two coumarins were synthesised by a 1-3 step reaction, with yields ranging from 6.2 to 35%. Next, we investigated the in vitro antitumour activity of these compounds. Compounds 1, 8, and 9 exhibited strong antitumour activity and were considered promising candidates in this field. In particular, compound 1 exhibited very strong inhibitory activity against HL-60, A-549, SMMC-7721, and SW480 cells, with IC50 values of 0.48, 0.82, 0.26, and 0.99 µM, respectively. Finally, the antitumour mechanism of compound 1 was investigated through network pharmacology and molecular docking analyses, which identified 22 key genes and 21 tumour pathways. AKT1, ALB, CASP3, ESR1, GAPDH, HSP90AA1, and STAT3 were considered as potential target hub genes for compound 1. These results will enable the future development of benzophenone and its derivatives.
