Therapeutic properties of Isoliquiritigenin with molecular modeling studies: Investigation of anti-pancreatic acinar cell tumor and as HMG-CoA reductase inhibitor for treatment of hypercholesterolemia

IntroductionIsoliquiritigenin, one of the components in the root of Glycyrrhiza glabra L., is a member of the flavonoids, which are known to have an anti-tumor activity in vitro and in vivo. HMG-CoA reductase inhibitors, called statins, are used to reduce the risk of heart disease by lowering blood cholesterol levels.Material and methodsHMG-CoA Reductase activity according to the method described by Takahashi S. et al. The structure of human HMG-COA reductase in the resolution of 2.22 Å with X-RAY diffraction method (PDB ID: 1HWK) was obtained from the PDB database.ResultsIn our study, inhibition result of Isoliquiritigenin on HMG-CoA reductase showed lower value IC50 = 193.77±14.85 µg / mL. For a better understanding of biological activities and interactions, the molecular docking study was accomplished. The results of molecular docking revealed that isoliquiritigenin with a docking score of -6.740 has a strong binding affinity to the HMG-COA reductase. Therefore, this compound could be considered as a potential inhibitor for the enzyme. Also, the properties of Isoliquiritigenin against common human pancreatic acinar cell tumor cell lines i.e. 266-6, TGP49, and TGP47 were evaluated.ConclusionsThe treated cells with Isoliquiritigenin were assessed by MTT assay for 48h about the cytotoxicity and anti-human pancreatic acinar cell tumor properties on normal (HUVEC) and human pancreatic acinar cell tumor cell lines i.e. 266-6, TGP49, and TGP47. The IC50 of Isoliquiritigenin were 262, 389, and 211 µg/mL against 266-6, TGP49, and TGP47 cell lines, respectively.
