Phenolic constituents from the roots of C. Ling and their bioactivity.

This research is the first to report the phytochemical investigation of C. Ling. Thirty-three compounds were isolated and characterised (), including a pair of undescribed isomers ( and ), one undescribed phenolics (), and 30 known compounds.

Diterpenoid and triterpenoid glycosides from .

Two new compounds, including a diterpenoid glycoside () and a triterpenoid glycoside (), along with six known compounds were isolated from . The structures of the new compounds were determined on basis of extensive spectral analysis and chemical method. Compounds - were evaluated for their insulin resistance effect and cytotoxic activity against the A549 and HepG2 cancer cell lines.

Curcumin suppresses AGEs induced apoptosis in tubular epithelial cells via protective autophagy.

Renal tubular cell apoptosis and tubular dysfunction is an important process underlying diabetic nephropathy (DN). Understanding the mechanisms underlying renal tubular epithelial cell survival is important for the prevention of kidney damage associated with glucotoxicity. Curcumin has been demonstrated to possess potent anti-apoptotic properties.
