Abstract:
Type 2 diabetes mellitus (T2DM), a progressive metabolic disease characterized by abnormal glucose and lipid metabolism, has become a serious threat to human health [1,2].
Farnesoid X receptor (FXR) belongs to a member of the nuclear receptor Superfamily [3] and has been reported to be associated with glucose metabolism. For example, in FXR−/− mice, the level of hepatic gluconeogenic gene expression was decreased after fasting, while blood glucose level and the hepatic glucose production in response to pyruvate challenge were declined [4]. However, the effect and mechanism of FXR regulating glucose metabolism in vivo are not clear. Thus, we aim to screen a small molecule FXR antagonist as a probe to explore the mechanism of FXR regulating glucose metabolism.
Here, we used the AlphaScreen assay to screen the FXR antagonist. Among the compounds, H7 was finally selected for its highly antipathogenic activity against FXR. Finally, H7 antagonized GW4064-induced reporter gene stimulation in transactivation assay, indicating that H7 was an FXR antagonist.
