formaldehyde under basic condition. Similarly, the electrochemical oxidation and the treatment of 6 under Knoevenagel reaction conditions are the other alternative procedure described for the preparation of these bis compounds. However, the first method lacks generality as it involves aqueous reaction media and the second procedure is useful to obtain only the methylene bridged bispyrone derivatives

inhibit NQO1 and computed binding affinity. We have solved the crystal structure of NQO1 complexed to a hybrid compound and find good agreement with the in silico model. For both MIA PaCa-2 pancreatic tumor cells and HCT116 colon cancer cells, dicoumarol shows the greatest toxicity of all compounds. Thus, we provide a computational, synthetic, and biological platform to generate competitive NQO1 inhibitors
