Molecular docking and simulation studies of some pyrazolone-based bioactive ligands targeting the NF- B signaling pathways.

Abstract

NF-κB has become a predominant regulator responsible for multiple physiological and pathological processes. NF-κB signaling pathway has canonical and non-canonical components which strategize the cancer-related metabolic processes. Non-canonical NF-κB pathways are known to contribute towards the chemoresistance of cancer cells. Consequently, NF-κB can be utilized as a potential therapeutic target for modifying the behaviour of tumor cells. In view of this, we herein report a series of pyrazolone-based bioactive ligands that potentially target NF- κB and, thereby, unveil their anticancer properties. The pharmacological screening of the synthesized compounds were carried out using various virtual screening techniques. The anticancer studies of synthesized pyrazolones showed that APAU exhibited the most potent effect against the MCF-7 cells with an IC50 value of 30μg/ml. Molecular docking studies revealed that the pyrazolones inhibited cell proliferation by targeting the NFκB signaling pathway. The molecular dynamics simulation studies predicted the stability and flexibility of pyrazolone-based bioactive ligands.
