  Psoralen Derivatives as Inhibitors of NF-κB/DNA Interaction: Synthesis, Molecular Modeling, 3D-QSAR, and Biological Evaluation

  摘要：

  Some new psoralen derivatives were synthesized and evaluated as inhibitors of NF-kappa B/DNA interaction, with the aim to investigate the structural determinants required to inhibit this interaction. Starting from molecular docking studies, several possible protein binding sites were proposed and several three-dimensional quantitative structure activity relationship (3D-QSAR) models were built using the docked poses of 29 (the most active psoralen in the series) as templates for alignment of the inhibitors. The selected best model was validated through the prediction of the activity of 17 novel compounds. All the experimental data agreed with the computational experiments, supporting the reliability of the computational approach. The hypothesis about the interaction with NF-kappa B was also supported by surface plasmon resonance based assays using compound 29. All the collected data allowed the identification of compound 29 as a potential candidate for the development of pharmaceutical strategies against the inflammatory phenotype of cystic fibrosis.

  peculiar mechanism of action consisting of a decarboxylation step before exerting their photobiological activity. The most active compound 2 is able to induce a noteworthy photocytotoxic effect, with GI50 values being submicromolar on human tumor cell lines and no effect in the dark. The involvement of DNA photoaddition after UVA light-mediated decarboxylation and ROS formation is responsible for its biological

  Nuclear Factor kappaB (NF-kappa B) plays a very important role in the control of gene expression and is deeply involved in several human pathologies. Accordingly, molecules targeting NF-kappa B dependent biological functions are considered of great interest. Virtual screening of furocoumarin libraries against NF-kappa B p50 allowed to rank compounds in respect to their expected ability to bind NF-kappa B and the identified compound might be considered for the development of analogs to be tested for biological activity on inhibition of NF-kappa B/DNA complex formation. The data reported in the present paper suggest that, following this approach, the best ranked compounds identified by virtual screening (a) strongly bind in silica to NF-kappa B and (b) efficiently inhibit the molecular interactions between P-32-labeled NF-kappa B double stranded DNA and p50 or p50/p65 complex. These data allowed to develop a novel lead of great interest for inhibiting NF-kappa B dependent biological functions. This novel molecule (compound 2), bearing a methyl group in the 9 position of the psoralen nucleus, exhibits high efficiency in inhibiting NF-kappa B/DNA interactions. In addition, we found that compound 2 is a potent inhibitor of IL-8 gene expression in TNF-alpha treated IB3-1 cystic fibrosis cells. Taken together, our data indicate that compound 2 might find an important place in the set of molecules of interest for the development of pharmaceutical strategies against the inflammatory phenotype of cystic fibrosis.
