β-Hydroxypropiovanillone 是一种天然化合物，对 α-葡萄糖苷酶 (α-glucosidase) 具有明显的浓度依赖性抑制作用 (IC50=257.8 μg/mL)。
β-Hydroxypropiovanillone, a natural compound, shows significant concentration-dependent inhibitory effects on α-glucosidase with an IC50 of 257.8 μg/mL[1].
β-hydroxypropiovanillone and its analogs can be obtained by chemoselective catalytic oxidation of lignin using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone/tert-butyl nitrite/O2, followed by cleavage of arylglycerol-β-aryl ether with zinc[2].In SYK-6 cells, β-hydroxypropiovanillone (HPV) is oxidized to vanilloyl acetic acid (VAA) via vanilloyl acetaldehyde (VAL). The resulting VAA was further converted into vanillate through the activation of VAA by coenzyme A[3].
