Biological Activity
4L2-P13D (0.5-5 μM; 72 h) reduces the expression of profibrotic factors (FN1, COL1A1) in TGF-β1-induced HK-2 cells in a dose-dependent manner[1].
4L2-P13D (0-50 μM; 24 h) exhibits no cytotoxicity against HK-2 cells even at concentrations as high as 50 μM[1].

Result:Significantly reduced expression levels of fibrosis markers FN1 and α-smooth muscle α-SMA.
Remarkably reduced proinflammatory markers (TNF-α, TGF-β1, IL-6, IL-1β) and kidney injury markers (Kim1, Ngal).
Reduced blood urea nitrogen (BUN) and creatinine levels.
Significantly improved collagen deposition, with the high-dose group showing superior efficacy compared to the low-dose group.
