D-Allose is a rare naturally occurring monosaccharide known to exert anti-proliferative effects on cancer cells. The effects of D-Allose on the cellular membranes of hormone-refractory prostate cancer cell line (DU145) hormone-sensitive prostate cancer cell line (LNCaP) and normal prostate epithelial cells (PrEC) were studied at the molecular level by phospholipid profiling using a shotgun lipidomic method.

Swertianine is a hydroxyexanthone that can be isolated from Swertia decussata. Swertianine has antioxidant activity by inhibiting lipid peroxidation, scavenging DPPH and superoxide free radicals. Swertianine also inhibits γ-ray induced DNA damage of pBR322 with protective effect.
