The discovery of tertiary-amine LXR agonists with potent cholesterol efflux activity in macrophages
摘要:
The liver X receptors (LXR) play a key role in cholesterol homeostasis and lipid metabolism. SAR studies around tertiary-amine lead molecule 2, an LXR full agonist, revealed that steric and conformational changes to the acetic acid and propanolamine groups produce dramatic effects on agonist efficacy and potency. The new analogs possess good functional activity, demonstrating the ability to upregulate LXR target genes, as well as promote cholesterol efflux in macrophages. (C) 2009 Elsevier Ltd.

The present invention relates to a method for promoting osteogenesis by contacting osteoblast progenitor cells with an LXR agonist. Said method is useful for the treatment or prevention of an imbalance in bone homeostasis in a subject using bone homeostasis-promoting compositions comprising an effective osteogenic stimulating amount of an LXR agonist in admixture with a pharmaceutically acceptable carrier. A further aspect is a method to produce bone tissue in vitro by contacting an LXR agonist with a population of osteoblast progenitor cells on a substrate, for a time sufficient to stimulate the generation of a matrix of bone tissue.
