Ecdysteroid agonist and antagonist activities in species of the Solanaceae.Many plant compounds are able to modulate growth and reproduction of herbivores by directly interacting with steroid hormone systems. In insects, several classes of phytochemicals, including the phytoestrogens, ecdysteroid agonists and antagonists with molting and reproduction. We investigated whether the anti-ecdysone activity may ecdysteroid agonists and antagonists due to interaction with the ecdysone receptor EcR using a reporter-gene assay and a cell differentiation assay of an ecdysone-responsive cell line, Cl. We tested rutin delays molt in insects ; four flavones: None of the phytochemicals tested were ecdysone agonists in the reporter-gene assay, but the flavones were able to significantly inhibit EcR-dependent gene transcription.
