The enzyme NRH:quinone oxidoreductase 2 (NQO2) is involved in the progression of various diseases and is known to be increased in some cancer cell lines. This study examined the activity of 3-arylidene-2-oxindoles, commonly used in the design of new anticancer drugs, as NRH:quinone oxidoreductase inhibitors. The most active compounds showed significant inhibition of NQO2, but there was no correlation between their inhibition activity and cytotoxic effect on cancer cells.
The enzyme NRH:quinone oxidoreductase 2 (NQO2) plays an important role in the pathogenesis of various diseases such as neurodegenerative disorders, malaria, glaucoma, COVID-19 and cancer. NQO2 expression is known to be increased in some cancer cell lines. Since 3-arylidene-2-oxindoles are widely used in the design of new anticancer drugs, such as kinase inhibitors, it was interesting to study whether such structures have additional activity towards NQO2. Herein, we report the synthesis and study of 3-arylidene-2-oxindoles as novel NRH:quinone oxidoreductase inhibitors. It was demonstrated that oxindoles with 6-membered aryls in the arylidene moiety were obtained predominantly as E-isomers while for some 5-membered aryls, the Z-isomers prevailed. The most active compounds inhibited NQO2 with an IC50 of 0.368 mu M. The presence of a double bond in the oxindoles was crucial for NQO2 inhibition activity. There was no correlation between NQO2 inhibition activity of the synthesized compounds and their cytotoxic effect on the A549 cell line.
