SB505124 is a selective inhibitor of TGF-β Receptor type I receptors (ALK4, ALK5, ALK7), with IC50 values of 129nM and 47nM for ALK4, ALK5, respectively[1]. SB505124 can inhibit the Wnt and TGF-β1 signaling pathways, reduce inflammatory responses, and decrease the levels of fibrosis markers (such as collagen, α-SMA and fibronectin)[2]. SB505124 has been widely used to inhibit the differentiation of Th17 cells and regulate inflammation in mouse models of arthritis[3].
In vitro, SB505124 treatment at 3μM for 10 days significantly inhibited the osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs), reduced the formation of mineralized matrix, and downregulated osteogenic-related genes[4]. Treatment with SB505124 (2.5μM) for 24 hours significantly enhanced the sensitivity of doxorubicin (DTX)-resistant DU 145 cells to DTX and induced cell death[5]. Pretreatment of rabbit conjunctival submucosal fibroblasts with 10µM SB505124 for 1 hour significantly reduced the level of pSmad2 induced by TGF-β2 as well as the expressions of CTGF and α-SMA[6].
In vivo, SB505124 treatment via intraperitoneal injection at a dose of 10mg/kg once every 12 hours for 5 days alleviated the extent of tertiary neurodegeneration and blood-brain barrier dysfunction in the perinatal mouse model with hypoxic-ischemic brain injury, and improved sensory-motor deficits[7]. SB505124 treatment for 2 weeks (5mg/kg/day; i.p.) caused the increase of erythrocytes in the peripheral blood and the normalized proportion of erythroblast cell clusters in the Lewis lung carcinoma (LLC) cell-xenograft mouse models[8].

Protocol
| Cell experiment [1]: | |
Cell lines | Human bone marrow mesenchymal stem cells (hBMSCs) |
Preparation Method | Human bone marrow mesenchymal stem cells (hBMSCs) were cultured in Dulbecco's Modified Eagle Medium (DMEM), supplemented with 4500mg/l D-glucose, 4mM L-glutamine, 110mg/l 10% sodium pyruvate, 10% fetal bovine serum (FBS), 1% non-essential amino acids, and 1% penicillin-streptomycin. The incubator temperature was set at 37°C, humidity at 95%, and CO2 concentration at 5% to maintain cell growth. The cells were seeded in 96-well plates, with 300μl of culture medium added to each well, and 0.3, 3, and 30μM of SB505124 were added respectively. The control group cells were added with DMSO. After 72h, cell viability was analyzed. |
Reaction Conditions | 0.3, 3, and 30μM; 72h |
Applications | SB505124 treatment significantly decreased the cell viability of U87MG cells at 30μM. |
| Animal experiment [2]: | |
Animal models | C57BL/6 mice |
Preparation Method | The C57BL/6 mice were raised in a standard environment and were allowed to freely consume food and water. 2×106 LLC cells were suspended in 100μl of sterile PBS, or an equal volume of PBS solution was injected subcutaneously into the left abdomen of 8-week-old male mice. From the 7th day to the 21st day after tumor implantation, 5mg/kg doses of SB505124 or DMSO were injected intraperitoneally daily. Under anesthesia, blood samples were drawn from the inferior vena cava of the mice for analysis. |
Dosage form | 5mg/kg/day for 2 weeks; i.p. |
Applications | SB505124 treatment attenuated the symptoms of cancer-related anemia in the LLC cell-xenograft mouse models. |
