Licochalcone C 能够抑制 α-葡萄糖苷酶 (α-glucosidase),其对 α-葡萄糖苷酶和蛋白酪氨酸磷酸酶 1B 的 IC50 值分别为 <100 nM 和 92.43 μM。
靶点IC50: <100 nM (α-glucosidase), 92.43 μM (PTP1B)。
体外研究Licochalcone C 可以抑制 α-葡萄糖苷酶,其 IC50 值分别为 <100 nM 和 92.43 μM 对应于 α-葡萄糖苷酶和 PTP1B。此外,Licochalcone C 还能浓度依赖性地诱导 T24 细胞凋亡。该化合物可以降低抗凋亡 mRNA(如 Bcl-2、Bcl-w 和 Bcl-XL)的水平,并增加促凋亡 mRNA(如 Bax 和 Bim)的表达。Bcl-2 家族抑制剂 ABT-737 可以减少 Licochalcone C 在 T24 细胞中诱导的凋亡。
化学性质Licochalcone C 是一种黄色结晶粉末,可溶于甲醇、乙醇和 DMSO 等有机溶剂。它来源于甘草根茎。
用途Licochalcone C 具有抗溃疡、抗菌消炎、降血脂以及清除自由基和抗氧化的作用,并可用于含量测定/鉴定/药理实验等。

Microbial conjugation studies of licochalcones (1–4) and xanthohumol (5) were performed by using the fungi Mucor hiemalis and Absidia coerulea. As a result, one new glucosylated metabolite was produced by M. hiemalis whereas four new and three known sulfated metabolites were obtained by transformation with A. coerulea. Chemical structures of all the metabolites were elucidated on the basis of 1D-, 2D-NMR and mass spectroscopic data analyses. These results could contribute to a better understanding of the metabolic fates of licochalcones and xanthohumol in mammalian systems. Although licochalcone A 4′-sulfate (7) showed less cytotoxic activity against human cancer cell lines compared to its substrate licochalcone A, its activity was fairly retained with the IC50 values in the range of 27.35–43.07 μM.
