metoxyetoxymethyl ether of cholesterol;3β-(2,5-dioxahexyloxy)-5-cholestene;(3S,8S,9S,10R,13R,14S,17R)-3-(2-methoxyethoxymethoxy)-10,13-dimethyl-17-[(2R)-6-methylheptan-2-yl]-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthrene
Design and synthesis of cholesterol-derived anti-apoptotic agents were described. The synthesized cholesterol analogs designed on the structural basis of ginsenoside Rk1 inhibited the undesirable apoptosis of human endothelial cells, which are induced by a vascular injury. In particular, analogue 1 possessing 4,6di-O-acetyl-2,3-dideoxyhex-2-enopyran linked to hydroxyl group of cholesterol exhibited the most effective anti-apoptotic activities at both 5 and 10 mu g/ml.
