SD-208 is a selective TGF-βRI (ALK5) inhibitor with IC50 of 48 nM, >100-fold selectivity over TGF-βRII.
LDN-214117 is a potent and selective BMP type I receptor kinase ALK2 inhibitor with IC50 of 24 nM.
Staurosporine is a potent PKC inhibitor for PKCα, PKCγ and PKCη with IC50 of 2 nM, 5 nM and 4 nM, less potent to PKCδ (20 nM), PKCε (73 nM) and little active to PKCζ (1086 nM) in cell-free assays. Also shows inhibitory activities on other kinases, such as PKA, PKG, S6K, CaMKII, etc. Phase 3.
Sotrastaurin is a potent and selective pan-PKC inhibitor, mostly for PKCθ with Ki of 0.22 nM in a cell-free assay; inactive to PKCζ. Phase 2.
Features:Unlike former PKC inhibitors, Sotrastaurin does not enhance apoptosis of murine T-cell blasts in a model of activation-induced cell death.
Enzastaurin (LY317615) is a potent PKCβ selective inhibitor with IC50 of 6 nM in cell-free assays, 6- to 20-fold selectivity against PKCα, PKCγ and PKCε. Phase 3.
GF109203X is a potent PKC inhibitor with IC50 of 20 nM, 17 nM, 16 nM, and 20 nM for PKCα, PKCβI, PKCβII, and PKCγ in cell-free assays, respectively, showing more than 3000-fold selectivity for PKC as compared to EGFR, PDGFR and insulin receptor.
Features:Greater selectivity than PKC inhibitor staurosporine. GF109203X is a chemical probe for studying PKC signal transduction pathways. Potential for use in a variety of cancers.
Go6976 is a potent PKC inhibitor with IC50 of 7.9 nM, 2.3 nM, and 6.2 nM for PKC (Rat brain), PKCα, and PKCβ1, respectively. Also a potent inhibitor of JAK2 and Flt3.
