Durian, known as the king of fruits, is native to Southeast Asia and popular in many countries. Bioactivity-guided fractionation of the peel of durian was applied to determine its bioactive constituents. Four novel phenolics, along with 16 known, were pur

New ruthenium(II) and iron(II) organometallic compounds of general formula [(η5-C5H5)M(PP)Lc][PF6], bearing carbohydrate derivative ligands (Lc), were prepared and fully characterized and the crystal structures of five of those compounds were determined by X-ray diffraction studies. Cell viability of colon cancer HCT116 cell line was determined for a total of 23 organometallic compounds and SAR's data analysis within this library showed an interesting dependency of the cytotoxic activity on the carbohydrate moiety, linker, phosphane coligands, and metal center. More importantly, two compounds, 14Ru and 18Ru, matched oxaliplatin IC50 (0.45 μM), the standard metallodrug used in CC chemotherapeutics, and our leading compound 14Ru was shown to be significantly more cytotoxic than oxaliplatin to HCT116 cells, triggering higher levels of caspase-3 and -7 activity and apoptosis in a dose-dependent manner.

Three new dammarane-type triterpenoid saponins, 1-3, were isolated and identified as (20S)-20-O-[β-D-xylopyranosyl-(1→6)-β-D- glucopyranosyl-(1→6)-β-D-glucopyranosyl]dammar-24-ene-3β, 6α,12β, 20-tetrol (1), (20S)-6-O-[(E)-but-2-enoyl-(1→6)-β- D-glucopyranosyl]dammar-24-ene-3β,6α,12β,20-tetrol (2), and (20S)-6-O-[β-D-xylopyranosyl-(1→2)-β-D-xylopyranosyl] dammar-24-ene-3β,6α,12β,20-tetrol (3) from the roots of Panax notoginseng (Burkill) F.H.Chen (Araliaceae). Their structures were elucidated on the basis of spectroscopic analyses, including 1D- and 2D-NMR techniques and HR-ESI-MS, as well as by acidic hydrolysis. Copyright
