Osthol (1) was isolated from the fruit of Cnidium monnieri as a cytotoxic principle. Its structure-activity relationship study reveals that the 3,4-olefinic bond is essential for its cytotoxic activity, and the prenyl (C5) unit attached at the 8 position enhances the cytotoxicity. Analogues 7 and 8 that have a longer alkoxy unit at the 7 position showed ten times higher cytotoxicity than 1.
Side-chain bromination of osthol using N-bromosuccinimide and some related reactions
Krishnaswamy, N. R.,Vijayan, K. K.
, p. 664 - 666 (2007/10/02)
Osthol when treated with N-bromosuccinimide under free radical conditions gives 8-(3-bromomethyl-2-butenyl)-7-methoxycoumarin (2), whereas under ionic conditions the product obtained is 8-(2-bromo-3-hydroxy-3-methylbutyl)-7-methoxycoumarin (5) which on reaction with sodium borohydride affords osthol epoxide (7) (meranzin).The epoxide 7 is converted back into the bromohydrin 5 by the action of HBr in dioxane and to 8-(2-amino-3-hydroxy-3-methylbutyl)-7-methoxycoumarin (8) by the action of ammonia.
