PXS 64
PXS 64, a mannose-6-phosphate (M6P) analogue. a lipophilic prodrug of PXS 25 (HY-181430). PXS 64 is an effective anti-fibrotic agent by inhibiting the activation of latent TGF-β1. PXS64, inhibits fibrosis via TGF-β1 pathway in human lung fibroblasts. PXS 64 reduces TGFβ-mediated collagen IV, fibronectin, MCP-1, and phospho-smad2 expression in kidney cells. PXS 64 reduces collagen deposition in dermal scar fibroblasts. PXS 64 can be used for the research of chronic kidney disease, idiopathic pulmonary fibrosis, scarring.

Descripciòn
In Vitro
PXS 64 (10 µM; 48 h) inhibits latent TGF-β1 activation, suppresses pro-fibrotic and pro-inflammatory marker expression, and selectively reduces TGF-β1-induced pSmad2 expression without affecting pAKT or pERK. PXS64 alone has no effect on\nfibronectin, collagen IV and MCP-1mRNA and protein expression[1].
PXS64 (1-10 µM; 24.5 h) demonstrates a significant inhibition of fibrotic markers ( fibronectin and collagen) in rhTGF-β1 stimulated NHLFs[2].
PXS64 (10 µM; 24 h) presents an improved phenotype in terms of their morphological appearance, as well as a decrease in fibrotic markers (collagen, CTGF, TGF-β3, tenascin C, αSMA and THBS1) in fibroblasts[2].
PXS64 exhibits a very potent anti-fibrotic activity (as measured by the inhibition of αSMA, fibronectin and collagen) in HF19 cells[2].

-
Concentration:1 µM, 3 µM, 10 µM

-
Cell Line:fibroblasts
-
Concentration:10 µM
-
Incubation Time:24 h
-
Result:Down-regulated a number of fibrotic associated genes, such as collagen, connective tissue growth factor (CTGF), TGF-β3, tenascin C, αSMA and thrombospondin 1 (THBS1).
Changed from a senescent, growth-arrested state (as expected to be seen in fibroblasts) to a regular fusiform, healthy phenotype.
