    • The present invention provides compositions comprising the ligand binding domain (LBD) of a farnesoid X receptor (FXR) in crystalline form. In alternative embodiments, the LBD of FXR is complexed with a ligand therefor. There are provided high resolution structures of FXR complexed with a novel high affinity agonist, fexaramine. The discovered structure of a FXR LBD provides the first three-dimensional view of the structural basis for FXR ligand binding. The present invention further provides a computer for producing a three-dimensional representation of FXR or a complex thereof, and a computer for determining at least a portion of the structure coordinates of FXR or a complex thereof. The present invention further provides methods of using this structural information to predict molecules capable of binding to FXR; to identify compounds with agonist, antagonist or partial agonist activity for FXR; and to determine whether a test compound is capable of binding to the LBD of FXR. The present invention further provides compositions comprising compounds identified by such invention methods.

    • A novel nuclear receptor, termed the steroid and xenobiotic receptor (SXR), a broad-specificity sensing receptor that is a novel branch of the nuclear receptor superfamily, has been discovered. SXR forms a heterodimer with RXR that can bind to and induce transcription from response elements present in steroid-inducible cytochrome P450 genes in response to hundreds of natural and synthetic compounds with biological activity, including therapeutic steroids as well as dietary steroids and lipids. Instead of hundreds of receptors, one for each inducing compound, the invention SXR receptors monitor aggregate levels of inducers to trigger production of metabolizing enzymes in a coordinated metabolic pathway. Agonists and antagonists of SXR are administered to subjects to achieve a variety of therapeutic goals dependent upon modulating metabolism of one or more endogenous steroids or xenobiotics to establish homeostasis. An assay is provided for identifying steroid drugs that are likely to cause drug interaction if administered to a subject in therapeutic amounts. Transgenic animals are also provided which express human SXR, thereby serving as useful models for human response to various agents which potentially impact P450-dependent metabolic processes.
    • 已经发现了一种称为类固醇和异种生物受体(SXR)的新型核受体,作为核受体超家族的新分支的广泛特异性感受器受体。 SXR与RXR形成异源二聚体,其可以结合并诱导存在于类固醇诱导细胞色素P450基因中的响应元件的转录,以响应数百种具有生物活性的天然和合成化合物,包括治疗类固醇以及膳食类固醇和脂质。 代替数百个受体,每个诱导化合物一个,本发明SXR受体监测诱导剂的总体水平以引发协同代谢途径中代谢酶的产生。 SXR的激动剂和拮抗剂被施用于受试者以实现依赖于调节一种或多种内源性类固醇或异种生物的代谢以建立体内平衡的多种治疗目标。 提供了用于鉴定如果以治疗量施用给受试者的可能引起药物相互作用的类固醇药物的测定。 还提供了表达人SXR的转基因动物,从而作为人类对各种可能影响P450依赖性代谢过程的药物的反应的有用模型。
