trans-cinnamate 4-monooxygenase plays a key role in the ability of phenylpropanoid metabolism to channel carbon to produce the 4-methoxybenzoyl group on the disaccharide moiety of OSW-1 (3beta,16beta,17alpha-trihydroxycholest-5-en-22-one 16-O-[O-[2-O-(4-methoxybenzoyl)-beta-D-xylopyranosyl]-(1->3)-2-O-acetyl-alpha-L-arabinopyranoside]). OSW-1 is about 10-100 times more cytotoxic than clinically applied anticanceragents such as mitomycin C, adriamycin, cisplatin, camptothecin, and paclitaxel, but has a low toxicity towards normal cells. This potency, in combination with a unique mechanism of action and selectivity toward malignant tumor cells, gives OSW-1 and its analogues great potential as anticancer agents |
