More Details: A new flavonoid, catechin-3-O-(3"-O-trans-cinnamoyl)-α-rhamnopyranoside, along with known compounds, catechin-3-O-α-rhamnopyranoside, 3-oxo-urs-12-en-28-oic acid, 2,4,6-trimethoxybenzoic acid, 2-butyl-D-fructofuranoside and 1-butyl-D-fructofuranoside, has been isolated from the stem bark of V. thyrsoidea. These compounds were assayed for inhibition of protease activity (cathepsins B and K) and against cancer cell lines. Catechin-3-O-(3"-O-trans-cinnamoyl)-α-rhamnopyranoside showed moderate inhibitory activity (IC50 = 62.02 µM) against cathepsin B while 2-butyl-D-fructofuranoside was the most potent against a strain of CNS (SF-295) and human leukemia (HL-60) with IC50 = 36.80 µM and IC50 = 25.37 µM, respectively.
