Antitumor studies. Part 1: Design, synthesis, antitumor activity, and AutoDock study of 2-deoxo-2-phenyl-5-deazaflavins and 2-deoxo-2-phenylflavin-5-oxides as a new class of antitumor agents

Novel 2-deoxo-2-phenyl-5-deazaflavins and 2-deoxo-2-phenylflavin-5-oxides were prepared as a new class of antitumor agents and showed significant antitumor activities against NCI-H 460, HCT 116, A 431, CCRF-HSB-2, andKB cell lines. In vivo investigation, 2-deoxo-10-methyl-2-phenyl-5-deazaflavin exhibited the effective antitumor activity against A 431 human adenocarcinoma cells transplanted subcutaneously into nude mouse. Furthermore, AutoDock study has been done by binding of the flavin analogs into PTK pp60c-src, where a good correlation between their IC50 and AutoDock binding free energy was exhibited. In particular, 2-deoxo-2-phenylflavin-5-oxides exhibited the highest potential binding affinity within the binding pocket of PTK.

The prepared 2-deoxo-2-phenyl-5-deazaflavins (1) and 2-deoxo-2-phenylflavin-5-oxides (2) exhibited significant antitumor activities against CCRF-HSB-2, KB, NCI-H460, A 431, and HCT 116 cells. A good correlation between IC50 and binding free energy for 1 and 2 was obtained by docking into PTK pp60c-src.Figure optionsDownload as PowerPoint slide
