Abstract

The natural product magnolol (1) and a selection of its bioinspired derivatives 2-5, were investigated by Inverse Virtual Screening in order to identify putative biological targets from a panel of 308 proteins involved in cancer processes. By this in silico analysis we selected tankyrase-2 (TNKS2), casein kinase 2 (CK2) and bromodomain 9 (Brd9) as potential targets for experimental evaluations. The Surface Plasmon Resonance assay revealed that 3-5 present a good affinity for tankyrase-2, and, in particular, 3 showed an antiproliferative activity on A549 cells higher than the well-known tankyrase-2 inhibitor XAV939 used as reference compound.

Keywords: Anti-cancer drugs; Biomimetic compounds; Inverse Virtual Screening; Tankyrase-2; Tankyrase-2 inhibitors.
