Ligupurpuroside B

SKU: orb1684457

Description

Ligupurpuroside B is a phenethyl glycoside natural product isolated from Ligustrum robustum. It demonstrates antioxidant activity, as evidenced by an IC50 of 80.4 μM in an AAPH-induced erythrocyte haemolysis assay, supporting its research use in oxidative stress studies.

Bioactivity

−

In Vitro

According to Stern-Volmer equation, fluorescence of lipase was quenched by Ligupurpuroside B via a static quenching mechanism because of formation of Ligupurpuroside B-lipase complex. Binding constants, number of binding sites & thermodynamic parameters were evaluated. The values of ΔGo (-25.085 kJ mol-1), ΔHo (-12.14 kJ mol-1) and ΔSo (+43.45 J mol-1 K-1) at 298 K indicated that Ligupurpuroside B-lipase interaction is spontaneous and hydrophobic interaction is the main force stabilizing the Ligupurpuroside B-lipase complex. The enzyme activity assay showed that Ligupurpuroside B inhibited lipase activity efficiently. Synchronous fluorescence spectra (SFS) suggested that Ligupurpuroside B is closer to Trp residues than to Tyr residues.
