Bio-guided fractionation of an extract from Tanacetum parthenium showing activity as mitotic blocker allowed the isolation and identification of santin 3, jaceidin 2 and centaureidin 1. The latter two closely related flavonols, which, to the best of our knowledge, are isolated here together for the
The CH2Cl2 extract of Tanacetum microphyllum exhibited antiinflammatory activity on PMA-mouse ear model. Two antiinflammatory flavonoids, 5,7-dihydroxy-3,6,4'-trimethoxyflavone (santin) (1) and 5,7-dihydroxy-3,4'-dimethoxyflavone (ermanin) (2), were isolated.
In our ongoing research into anti-inflammatory compounds from Tanacetum microphyllum, four naturally occurring flavonoids (santin, ermanin, centaureidin and 5,3'-dihydroxy-4'-methoxy-7-methoxycarbonylflavonol) and one sesquiterpene lactone (hydroxyachillin) isolated from this plant, were evaluated
In the present study, the effects of compounds extracted from Tanacetum microphyllum, four flavonoids and one sesquiterpene lactone, on arachidonic acid metabolism in cellular systems were examined. In the PGE2- and LTC4-release assay, most compounds did not exhibit any significant effect. Only
Plant flavonoids show anti-inflammatory activity both in vitro and in vivo. Some flavonoids have been reported previously to inhibit nitric oxide (NO) and prostaglandin E2 (PGE2) production by suppressing inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. The present
Human schistosomiasis, caused by trematode worms of the genus Schistosoma, is one of the most significant neglected tropical diseases, affecting more than 200 million individuals worldwide and praziquantel is the only available drug to treat this disease. Artemisia absinthium L. and Tanacetum
