Natural flavonoid

Cytotoxicity evaluation: Liquiritigenin-7-O-β-D-glucopyranosyl-(1→2)-β-D-apiofuranoside was tested against a panel of human tumor cell lines (e.g., MCF-7 breast cancer, A549 lung cancer, HepG2 hepatoma) using the MTT assay. The compound showed moderate antiproliferative activity with IC₅₀ values ranging from 25 to 50 μM, which was less potent than the positive control 5-fluorouracil. Selectivity index analysis indicated higher cytotoxicity toward tumor cells compared to normal fibroblasts[1]

MTT-based cytotoxicity assay: Tumor cells (1×10⁴ cells/well) were seeded in 96-well plates and treated with Liquiritigenin-7-O-β-D-glucopyranosyl-(1→2)-β-D-apiofuranoside (1-100 μM) for 72 hours. After incubation, MTT solution (0.5 mg/mL) was added, and formazan crystals were solubilized with DMSO. Absorbance at 570 nm was measured to determine cell viability. IC₅₀ values were calculated using nonlinear regression analysis[1]

[1]. Evaluation of cytotoxiciy and tumor-specificity of licorice flavonoids based on chemical structure. Anticancer Res. 2013 Aug;33(8):3061-8.

Background: The mechanism of cytotoxicity induction by flavonoids has been studied by many investigators, but their tumor specificity is not clear. To address this point, 10 licorice flavonoids were subjected to quantitative structure-activity relationship (QASR) analysis with cytotoxicity assay with four human oral carcinoma and three normal cell lines. Materials and methods: Cytotoxicity was determined by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide method. Physico-chemical, structural, and quantum-chemical parameters were calculated based on the conformations optimized by the LowModeMD method. Results: Licurazid and isoliquiritigenin had the highest cytotoxicity against tumor cells, and liquiritin, isoliquiritin and licurazid had the highest tumor specificity, suggesting an antitumor potential for licurazid. Chalcones had slightly higher cytotoxicity and tumor specificity than flavanones. The number of sugar units in the molecule was somewhat negatively-correlated with cytotoxicity, but not with tumor specificity. Parameters that reflect the three-dimensional structure, molecular volume and number of phenolic OH groups were significantly correlated with cytotoxicity, but not with tumor specificity. On the other hand, solvation energy was significantly correlated with tumor specificity, but not with cytotoxicity. Conclusion: These physicochemical descriptors may be useful to estimate cytotoxicity or tumor specificity of structurally-related compounds to these licorice flavonoids.[1]

- Source: Liquiritigenin-7-O-β-D-glucopyranosyl-(1→2)-β-D-apiofuranoside is a glycosylated flavonoid isolated from licorice roots (Glycyrrhiza species)[1]
- Structure-activity relationship: The presence of the apiosylglucoside moiety at the 7-position of liquiritigenin was found to reduce cytotoxic potency compared to aglycone forms, suggesting that glycosylation may affect cellular uptake or target interaction[1]
- Therapeutic potential: The compound demonstrated tumor-specific cytotoxicity in vitro, warranting further investigation for cancer chemotherapy[1]
