VDR agonist 4
VDR agonist 4 is an orally active potent VDR agonist. VDR agonist 4 exerts VDR-dependent antifibrotic activity by regulating multiple fibrosis-related genes to suppress α-SMA and collagen I production, thereby inhibiting hepatic stellate cell (HSC) activation. VDR agonist 4 improves CCl4 (HY-RS16594)-induced hepatic fibrosis in mice. VDR agonist 4 can be used for liver fibrosis research.

Biological Activity
VDR agonist 4 (compound B15) (0.1 μM, 48 h) downregulates 991 differentially expressed genes (DEGs) and upregulates 249 DEGs in LX-2 cells, and increases the expression of CYP24A1[1].
VDR agonist 4 presents a favorable safety profile, with no significant cytotoxicity in LX-2 cells (IC50 > 50 μM) and negligible hERG-mediated cardiotoxicity (IC50 > 30 μM)[1].
VDR agonist 4 (0.1 μM, 24 h) significantly inhibits the expression of COL1A1, ACTA2, and collagen I in LX-2 cells, while this inhibitory effect is abolished upon VDR depletion, thereby demonstrating that its potent antifibrotic activity is strictly VDR-dependent[1].
VDR agonist 4 (0.1 μM, 48 h) downregulates core fibrogenic pathways (TGFβ/SMAD3, PEGF, JAK) and collagen synthesis genes (COL1A2, COL3A1) in LX-2 cells, while upregulating collagen degradation genes (MMP1, MMP3), thereby demonstrating the suppression of collagen production and promotion of its breakdown[1].

Animal Model:Male C57BL/6 mice (8 weeks old) intraperitoneally injected with CCl4/corn oil (1/50, v/v) mixture at a dose of 0.5 mL/kg three times a week for 4 weeks[1]
-
Dosage:500 μg/kg
-
Administration:p.o., five times weekly for 2 weeks
-
Result:Exhibited potent inhibitory effects on target gene expression (Fn, Ctgf, Timp-1), with efficacy comparable to Calcipotriol (HY-10001).
Resulted in marked attenuation of hepatic inflammation and significant amelioration of fibrotic lesions, as evidenced by reduced inflammatory markers and collagen accumulation.
Resulted in a significant decrease in ALT, AST, and TBA levels.
Did not result in increased serum calcium levels.
