DW532
DW532 is a dual inhibitor of tubulin and tyrosine kinase, with IC50 values of 4.9 μM and 5.5 μM against EGFR and VEGFR2, respectively, and a KD of 3.6 μM for tubulin. DW532 induces cell cycle arrest at the G2/M phase, triggers cell apoptosis via caspase-related pathways, and inhibits angiogenesis. DW532 can be used for research related to cancers (e.g., breast cancer).

DW532 (1-10 μM; 2 h) dose-dependently inhibits ligand-induced VEGFR2 activation and its downstream signaling pathways in HUVECs, as well as EGFR activation and its downstream signaling pathways in A431 human epithelial cancer cells[1].
DW532 (10-40 μM; 30 min) is a microtubule destabilizer that inhibits tubulin polymerization in vitro in a dose-dependent manner[1].
DW532 (0.1-10 μM; 12 h) dose-dependently inhibits tubulin polymerization in human breast cancer MDA-MB-468 cells, reduces the level of polymerized tubulin and increases the level of soluble tubulin[1].
DW532 (10 μM; 6 h) disrupts the microtubule network in human lung cancer A549 cells and induces diffuse tubulin staining, which is consistent with the characteristics of microtubule destabilization[1].
DW532 (72 h) potently and non-selectively inhibits the proliferation of a panel of 16 human cancer cell lines, with a mean IC50 of 1.82 μM[1].
DW532 (0.1-10 μM; 6 h) dose-dependently inhibits tube formation in human umbilical vein endothelial cells (HUVECs) in vitro[1].
DW532 (10 μM; 12 h) disrupts mitotic spindle assembly in human lung cancer A549 cells, induces chromosome dispersion and multipolar spindle formation, and rarely causes the appearance of monopolar spindles[1].
DW532 (1-10 μM; 24 h) induces G2/M phase arrest in MDA-MB-468, A549, PC-3, KB, K562 and A431 human cancer cells, accompanied by altered levels of mitosis-related proteins cyclin B1, p-CDK1 and p-H3[1].
DW532 (0.1-20 μM; 48 h) induces dose-dependent apoptosis in KB, MDA-MB-468 and A431 human cancer cells via a caspase-related mechanism[1].

-
Cell Line:human umbilical vein endothelial cells (HUVECs), A431 human epithelial cancer cells
-
Concentration:1, 5 and 10 μM
-
Incubation Time:2 h (pre-incubated prior to 15 min ligand stimulation)
-
Result:Dose-dependently inhibited VEGF-induced phosphorylation of VEGFR2 and its downstream target Akt in HUVECs.
Similarly inhibited EGF-induced phosphorylation of EGFR and downstream Akt in A431 cells.
-
Cell Line:MDA-MB-468 human breast carcinoma cells
-
Concentration:0.1, 1 and 10 μM
-
Incubation Time:12 h
-
Result:Dose-dependently decreased polymerized tubulin in pellets and increased soluble tubulin in supernatants, promoting the transition of cellular tubulin from polymerized to free state.
-
Cell Line:A549 human lung cancer cells
-
Concentration:10 μM
-
Incubation Time:6 h
-
Result:Disrupted the intact, stretched microtubule network seen in untreated cells, resulting in dispersed tubulin staining similar to that induced by the microtubule destabilizer vincristine (VCR).
-
Cell Line:A549 human lung cancer cells
-
Concentration:10 μM
-
Incubation Time:12 h
-
Result:Induced scattered chromosomes in the cytoplasm, formation of multipolar spindles, and a small proportion of monopolar spindles, consistent with traditional microtubule destabilizers.
-
Cell Line:KB mouth epidermal carcinoma cells, MDA-MB-468 human breast carcinoma cells, A431 human epithelial carcinoma cells
-
Concentration:0.1, 1 and 10 μM (Annexin V/PI); 0.1, 1, 5, 10 and 20 μM (Western Blot)
-
Incubation Time:48 h
-
Result:Induced dose-dependent apoptosis: ~59.7% of KB cells underwent apoptosis at 1 μM, and ~70% at 10 μM.
Dose-dependently increased cleavage of caspase-3, caspase-9, and PARP, indicating a caspase-related apoptosis mechanism.
-
Cell Line:MDA-MB-468, A549, PC-3, KB, K562, and A431 human cancer cells
-
Concentration:1 and 10 μM
-
Incubation Time:24 h
-
Result:Arrested all six tested cell lines at the G2/M phase.
Increased levels of mitotic markers cyclin B1 and p-H3, and decreased levels of phosphorylated (inhibitory) CDK1 (Tyr15).
