Description:
Tracheloside significantly decreases the activity of alkaline phosphatase (AP), an estrogen-inducible marker enzyme, with an IC(50) value of 0.31 microg/ml, a level of inhibition comparable to that of tamoxifen (IC(50) = 0.43 microg/ml).

An anti-estrogenic lignan glycoside, tracheloside, from seeds of Carthamus tinctorius.
The lignan glycoside, Tracheloside, was isolated from seeds of Carthamus tinctorius (Compositae) as an anti-estrogenic principle against cultured Ishikawa cells by employing a bioassay-linked HPLC-ELSD method.
METHODS AND RESULTS:
Tracheloside significantly decreased the activity of alkaline phosphatase (AP), an estrogen-inducible marker enzyme, with an IC(50) value of 0.31 microg/ml, a level of inhibition comparable to that of tamoxifen (IC(50) = 0.43 microg/ml).

Lack of significant inhibitory effects of a plant lignan tracheloside on 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)-induced mammary carcinogenesis in female Sprague-Dawley rats.
Tracheloside, one of the plant lignans which can be extracted from the debris after safflower oil is produced from the seeds of Carthamus tinctorious, is an analogue of another plant lignan, arctiin, the side-chain C-2 of the five-membered ring being changed from a hydrogen to a hydroxyl group. We have already demonstrated that arctiin has chemopreventive effect on mammary carcinogenesis. Therefore, chemopreventive effects of Tracheloside on the initiation or post-initiation period of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)-induced mammary carcinogenesis in female rats were examined.
METHODS AND RESULTS:
For initiation, female Sprague-Dawley (SD) rats at the 6 weeks of age were given intragastric administrations of 100 mg/kg body weight of PhIP once a week for 8 weeks. The animals were treated with 0.2 or 0.02% Tracheloside during or after this carcinogen exposure. Control rats were fed basal diet with PhIP initiation or 0.2% Tracheloside or basal diet alone without initiation throughout the experimental period. All surviving animals were necropsied at the week 52 of administration. There were no clear treatment-related changes with statistical significance in all parameters for mammary carcinomas measured in this experiment.
CONCLUSIONS:
These results indicate that Tracheloside may not exert significant effects on PhIP-induced mammary carcinogenesis at least under the present experiment condition.
