Constrained phytoestrogens and analogues as ERβ selective ligands
摘要:
A new series of ERbeta (ERbeta) selective ligands has been prepared. One of the compounds 6, structurally related to the phytoestrogen apigenin 4, displays a binding preference for ERbeta over ERalpha of over 40-fold. In addition to its binding selectivity, 6 was able to potently induce metallothionein (an ERbeta specific response in human SAOS-2 cells) while demonstrating low potency in an ERalpha dependant ERE-tk luciferase assay in MCF-7 cells. Such receptor and cell selectivity could make 6 a useful molecular probe for better understanding the role of ERbeta in mammalian physiology. (C) 2003 Elsevier Science Ltd. All rights reserved.

Osteoporosis is one of the major problems in our aging society. Osteoporosis results in bone fracture in older members of the population, especially in post-menopausal women. In traditional medicine, there are many natural crude drugs that have the potential for use to treat bone diseases. So far, there is no report in literature on anti-osteoporosis (bone forming) activity of
Butea
species. It was thought to study the anti-osteoporotic activity of this plant. Thus, the present invention provides a pharmaceutical composition from the extracts of
Butea monosperma
for prevention or treatment of bone disorders, process of preparation and use thereof.

[FR] L'ostéoporose est l'un des problèmes majeurs de notre société vieillissante. L'ostéoporose se traduit par une fracture des os chez les personnes d'un certain âge, en particulier les femmes ménopausées. Dans la médecine traditionnelle, il existe de nombreux médicaments bruts naturels ayant le potentiel de traiter les maladies osseuses. Jusqu'à présent, la littérature ne fait nullement état de l'activité anti-ostéoporose (de formation osseuse) de l'espèce appelée Butea. On a envisagé l'étude de l'activité anti-ostéoporotique de cette plante. Ainsi, la présente invention porte sur une composition pharmaceutique à base d'extraits de Butea monosperma pour la prévention ou le traitement de troubles osseux, son processus d'élaboration et son utilisation.
