Application

SD-208 was used to inhibit the activity of ALK5 kinase in bovine retinal vascular cells.2

Biochem/physiol Actions

SD-208 is TGF-βR I kinase inhibitor with IC50 =49 nM based on direct enzymatic assay of TGFRI kinase (ALK5) activity with a specificity of >100-fold against TGFRII and at least 17-fold over members of a panel of related protein kinases including p38a, p38b, p38d, JNK1, EGFR, MAPKAPK2, MKK6, ERK2, PKC, PKA, PKD, CDC2, and CaMKII.
SD-208 is an inhibitor of TGF β receptor 1 kinase that is reportedly effective against human malignant gliomas. It increases the lytic activity and tumor infiltration by polyclonal natural killer cells, CD8 T cells and macrophages.1

Immunotherapy with chimeric antigen receptor (CAR)-engineered T-cells is effective in some hematologic tumors. In solid tumors, however, sustained antitumor responses after CAR T-cell therapy remain to be demonstrated both in the pre-clinical and clinical setting. A perceived barrier to the

The cytokine transforming growth factor (TGF)-beta, by virtue of its immunosuppressive and promigratory properties, has become a major target for the experimental treatment of human malignant gliomas. Here we characterize the effects of a novel TGF-beta receptor (TGF-betaR) I kinase

The transforming growth factor (TGF)-β and vascular endothelial growth factor (VEGF) pathways have a major role in the pathogenesis of glioblastoma, notably immunosuppression, migration, and angiogenesis, but their interactions have remained poorly understood. We characterized TGF-β pathway activity in 9

Purpose. An early hallmark of preclinical diabetic retinopathy is thickening of the capillary basal lamina (BL). TGF-beta, a multipotent cytokine acting through its receptors ALK5 and -1, has been postulated to be involved in this phenomenon. In light of this

Glioblastoma is the most common and aggressive intrinsic brain tumor in adults. Self-renewing, highly tumorigenic glioma-initiating cells (GIC) have been linked to glioma invasive properties, immunomodulation, and increased angiogenesis, leading to resistance to therapy. TGF-β signaling has been associated with
