  Ecdysteroids and a sucrose phenylpropanoid ester from Froelichia floridana

  摘要：

  Phytoecdysteroid glycosides (1-5) and a phenylpropanoid ester of sucrose (6) were isolated from the whole plant of Froelichia floridana, along with eight known compounds including three ecdysteroids (7-9), four flavonoids (10-13), and one phenolic compound (14). Structures were determined using a combination of spectroscopic techniques. Compounds 1, 2 and 6-14 were tested in vitro for their activity against human DNA topoisomerase I. Compound 13 (diosmetin) showed marginal inhibition against topoisomerase I with IC50 of 130 mu M in conjunction with low intercalation ability. (C) 2009 Elsevier Ltd. All rights reserved.
