Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) is a phosphatase having both protein and lipid phosphatase activities, and is known to antagonize the phosphoinositide 3-kinase/AKT (PI3K/AKT) signaling pathway, resulting in tumor suppression. PTEN is also known to play a role in the regulation of numerous transcription factors. Amplified in(More)
Ursolic acid, oleanolic acid, glycyrrhetinic acid, and betulinic acid, the representatives of pentacyclic triterpenes, were modified by introducing 2-methylene-3-oxo group as exocyclic α,β-unsaturated ketone moiety in ring A. The anti-bacterial and anti-tumor activities of these derivatives were assayed by comparing with the parent compounds. Results(More)
