A series of 4-(amido-biarylether)-quinolines was prepared as potential LXR agonists. Appropriate substitution with amide groups provided high affinity LXR ligands, some with excellent potency and efficacy in functional assays of LXR activity. Novel amide 4g had a binding IC(50)=1.9 nM for LXRbeta and EC(50)=34 nM (96% efficacy relative to T0901317) in an ABCA1 gene expression assay in mouse J774 cells, demonstrating that 4-(biarylether)-quinolines with appropriate amide substitution are potent LXR agonists.

Acute kidney injury (AKI) is a clinical syndrome characterized by a rapid decline in renal function. Renal ischemia-reperfusion injury (RIRI) is one of the main causes of AKI with the underlying mechanism incompletely clarified. The liver X receptors (LXRs), including LXRα and LXRβ, are members of the nuclear receptor superfamily.

The changes in the level of small GTPase ARL4C are associated with the initiation and progression of many different cancers. The content of ARL4C varies greatly between different tissues, and the induction of ARL4C expression leads to changes in cell morphology and proliferation. Although ARL4C can bind alpha-tubulin and affect intracellular transport, the role of ARL4C in the functioning of the tubulin cytoskeleton remained unclear.

Breast cancer (BC) ranks among the most prevalent malignancies affecting women, with advanced-stage patients facing an increased mortality risk. Myeloid-derived suppressor cells (MDSCs) contribute significantly to poor prognostic outcomes. Research has concentrated predominantly on the immunological mechanisms underlying MDSC functions, but a comprehensive investigation into the metabolic interactions between BC cells and MDSCs is lacking.

In response to agonists, LXRs induce the expression of key lipid homeostasis regulators. Crosstalk between LXRs and inflammatory signals exist in a cell type- and gene-specific manner.

A plethora of studies have demonstrated the crucial role played by Liver X Receptors (LXRs) in cancer. However, whether LXRs activation results in pro-versus anti-tumor effects is still matter of debate. Recently, we have reported the ability of 22(S)-hydroxycholesterol-3-sulfate (PFM037) to antagonize LXRα activity, and, at the same time, its capability to improve in-vivo anti-tumor immune responses.
