SU 16f

SU16f is a potent and selective PDGFRβ inhibitor with IC50s of 10 nM, 140 nM, 2.29 μM for PDGFRβ, PDGFR1, PDGFR2, respectively[1]. Neutralization of PDGFRβ receptor by SU16f blocks the promoting role of GC-MSCs (gastric cancer-derived mesenchymal stem cells) conditioned medium in gastric cancer cell proliferation and migration[2].

SU16f (20 μM; for 8 hours) pretreatment inhibits the promoting role of GC-MSC-CM in SGC-7901 cell proliferation[1]. SU16f (20 μM; for 8 hours) significantly abolishes PDGFRβ activation in SGC-7901 by GC-MSC-CM. SU16f pretreatment results in the upregulation of E-cadherin and downregulation of N-cadherin, Vimentin, and α-SMA. SU16f pretreatment leads to downregulation of p-AKT, Bcl-xl, and Bcl-2 levels and upregulation of Bax expression in SGC-7901 cells by GC-MSC-CM [1]. Cell Proliferation Assay[1] Cell Line: SGC-7901 cells in GC-MSC/SGC-7901 co-culture system Concentration: 20 μM Incubation Time: 8 hours Result: Inhibited the promoting role of GC-MSC-CM in SGC-7901 cell proliferation. Western Blot Analysis[1] Cell Line: SGC-7901 cells Concentration: 20 μM Incubation Time: 8 hours Result: Significantly abolished PDGFRβ activation in SGC-7901 by GC-MSC-CM, and resulted in the upregulation of E-cadherin and downregulation of N-cadherin, Vimentin, and α-SMA.
