GW296115
GW296115 is a multi-target inhibitor with the following IC50 values against its targets: 8.4 nM for BRSK2, 21 nM for BRSK1, 1.8 μM for PDGFRβ, 5.5 nM for STK17B/DRAK2, 28 nM for DRAK1, 20 nM for PHKG1, and 89 nM for DCAMKL3. GW296115 downregulates the phosphorylation of S317 site on ULK1 and S351 site on P62, which are AMPK substrates driven by BRSK2. GW296115 does not alter the phosphorylation level of AMPK at T172, reduces nutrient deprivation-mediated Autophagy and autophagosome formation, and enhances Apoptosis. GW296115 exhibits anticancer activity against triple-negative breast cancer. GW296115 is applicable for breast cancer-related research.

GW296115 (1 μM) inhibits 25 out of 403 wild-type human kinases by over 90% at a concentration of 1 μM, with a selectivity index of 0.062[1].
GW296115 potently inhibits 6 IDG dark kinases in enzymatic assays, with IC50 values ranging from 5.5 nM (DRAK2) to 89 nM (DCAMKL3)[1].
GW296115 (1 μM; 72 h) exerts no effect on cell proliferation in 17 tested cancer cell lines and normal cell lines (including non-malignant MCF10A and MRC-5) following treatment at 1 μM for 72 h[1].
GW296115 (incubated for 2 h) potently binds to BRSK2 in living HEK293 cells with an IC50 of 107 nM, confirming that it is a cell-active BRSK2 inhibitor[1].
GW296115 (2.5 μM; 2-6 h) abolishes BRSK2-induced phosphorylation of AMPK substrates in HEK293T cells (this effect is observed at both 2 h and 6 h) and induces hyperphosphorylation of BRSK2 at the T174 site[1].
GW296115 (2-5 μM) inhibits autophagy and enhances apoptosis in MDA-MB-231 triple-negative breast cancer cells, while it also inhibits autophagy and enhances apoptosis in BT-474 estrogen receptor-positive breast cancer cells[2].
GW296115 (2 μM; 24 h) inhibits the growth of MDA-MB-231 triple-negative breast cancer cells[2].
GW296115 (2-3 μM; 72 h) reduces the 3D invasiveness of MDA-MB-231 triple-negative breast cancer cells[2].

-
Concentration:2.5 μM
-
Incubation Time:2 h, 6 h
-
Result:Ablated wild-type BRSK2-induced AMPK substrate phosphorylation at both 2-h and 6-h time points.
