Potent LIM kinase inhibitor; antitumor
4745 | LIMKi 3

IC50 values are 7 and 8 nM for LIMK1 and LIMK2 respectively. Inhibits cofilin phosphorylation in MDA-MB-231 breast cancer cells. Reduces MDA-MB-231 tumor cell invasion in a 3D matrigel invasion assay.

Potent and selective BRD4 bromodomain inhibitor
5173 | MS 436

Ki = 30 - 50 nM for BrD1; exhibits 10-fold selectivity for BrD1 over BrD2. Blocks BRD4 transcriptional activity in lipopolysaccharide-induced production of both nitric oxide and IL-6 in mouse macrophages (IC50 values are 3.8 and 4.9 μM, respectively).

Related Products: I-BET 151 I-CBP 112 (+)-JQ1
sFRP-1 inhibitor; increases Wnt signaling
4767 | WAY 316606

Inhibits secreted frizzled-related protein-1 (sFRP-1) (IC50 = 0.65 μM); prevents sFRP-1 from interacting with Wnt and thus increases Wnt signaling. Increases total bone area in a murine calvarial organ culture assay.

Ki = 0.1 nM. Induces cell mitotic arrest and apoptosis in vitro. Inhibits the growth of a range of tumor cells in vitro, including colon (HCT 116), prostate (PC-3) and leukemia (K-562) cancer cell lines. Causes tumor regression in human tumor xenograft models in vivo, including colon (Colo205), lung (H69) and breast (MCF7) cancer cell xenografts.
