Go6976Go6976 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. |
Erk5 activation depends on Mek5, classical PKC and Mek1/2. MOVAS cells were serum-starved overnight and then treated for 1 h if not indicated otherwise with inhibitors targeting Jnk (SP600125, 10 μM), p38 (SB203580, 10 μM), Mek1/2 (CI-1040, 3 μM), Jak2 (AG490, 10 μM), Src (SU6656, 0.5 μM), Go6983 (PKC, 1 μM), Gö6976 (classical PKC, 1 μM), proteasomes (MG132, 25 μM), TPA (100 ng/ml for 15 min to activate PKCs or overnight to inhibit) and Mek5 (BIX02189, 1 μM), as well as Ca2 + chelators (EDTA, 2 mM; BAPTA-AM, 10 μM; both with 30 min preincubation), followed by stimulation with 20 ng/ml PDGF-BB for 10 min. Total cell lysates (TCL) were prepared and subjected to SDS-PAGE. Erk5 and PDGFRβ activities were measured by band shift and Tyr857 phosphorylation, respectively, using immunoblotting. Panel E and G show representative immunoblots. |

DaphnoretinDaphnoretin (Dephnoretin, Thymelol), a biologically active compound isolated from Wikstroemia indica C.A. Mey., is a protein kinase C (PKC) activator. Daphnoretin inhibits the proliferation, invasion, and migration of tumor cells and promote its apoptosis by regulating the activity of Akt signal pathway. |
