LY294002LY294002 (SF 1101, NSC 697286) is the first synthetic molecule known to inhibit PI3Kα/δ/β with IC50 of 0.5 μM/0.57 μM/0.97 μM, respectively; more stable in solution than Wortmannin, and also blocks autophagosome formation. It not only binds to class I PI3Ks and other PI3K-related kinases, but also to novel targets seemingly unrelated to the PI3K family. LY294002 also inhibits CK2 with IC50 of 98 nM. LY294002 is a non-specific DNA-PKcs inhibitor and activates autophagy and apoptosis. |
Inhibition of PI3K, ERK and mTOR prevents the activation of S6K1 and S6 induced by suppression of PKD1 activity. A549 cells were incubated in the absence (-) or presence of either 5 uM Kb or 5 uM Kb and 20 uM LY294002 or 5 uM Kb and 10 uM BKM120 (as indicated) for 1 h prior to stimulation of cells with 50 nM PMA for 30 min and 1 h.

Silmitasertib (CX-4945)Silmitasertib (CX-4945) is a potent and selective inhibitor of CK2 (casein kinase 2) with IC50 of 1 nM in a cell-free assay, less potent to Flt3, Pim1 and CDK1 (inactive in cell-based assay). Silmitasertib induces autophagy and promotes apoptosis. Phase 1/2. |

LY364947LY364947 is a potent ATP-competitive inhibitor of TGFβR-I with IC50 of 59 nM in a cell-free assay, shows 7-fold selectivity over TGFβR-II. |
The cytoplasmic and nuclear proteins were separated and the protein expression levels were determined by performing western blotting. LY364947 (1 uM), which is a potent ATP-competitive inhibitor of TGF-βRI, was used as the positive control. GAPDH and PARP were used as cytosolic and nuclear markers, respectively. |

| S7085 |
IWP-2IWP-2 is an inhibitor of Wnt processing and secretion with IC50 of 27 nM in a cell-free assay, selective blockage of Porcn-mediated Wnt palmitoylation, does not affect Wnt/β-catenin in general and displays no effect against Wnt-stimulated cellular responses. IWP-2 specifically inhibits CK1δ. |
KIF3A knockdown promotes both ligand secretion and intracellular signalling of the Wnt/β-catenin pathway in NSCLC cell lines. (c,d) SuperTOPFlash reporter assay to examine the effect of KIF3A knockdown on signalling pathway activation by autocrine or exogenous WNTs in A549 and SW900 cell lines. A549 and SW900 cells were incubated with DMSO or IWP-2 (30 μ M) for 48 h, and then treated with BSA or WNT3A (100 ng/ml) for additional 24 h. Luciferase reporter activity was calculated by dividing TOP/RL ratio by FOP/RL ratio (n = 3; error bars indicate SEM; p-value was determined by one-way ANOVA). *P < 0.05; **P < 0.01.
