Background:

DMXAA (Vadimezan, AS-1404) is a selective inhibitor of DT-diaphorase with Ki50 and IC50 value of 20 μM and 62.5 μM, respectively [1, 2].


DT-diaphorase (DTD) is an obligate two-electron reductase and it has been reported that the expression of DTD is elevated in a variety of cancers [2].


DMXAA (Vadimezan) a potent DT-diaphorase inhibitor and is also reported as a multi-inhibitor for several kinases. When tested with sections of colon 38 tumors isolated from C57Bl/6 mice at different time, DMXAA (Vadimezan) (25 mg/kg) showed a high induction on endothelium cell apoptosis after 30 min treatment and showed intensely apoptotic vessels and large areas of necrosis of the tumor after 3 h treatment [2]. In NSCLC cell line A549 cells, DMXAA (Vadimezan) treatment arrested cell in G1 phase and induced cell apoptosis and autophagy by increasing cytosolic level of cytochrome and activation of caspase3 in a dose dependent manner from 0.1 μM to 10 μM [3].


In C57Bl/6 mice model with luciferase-expressing murine GL261 glioma cells subcutaneous xenograft, administration of DMXAA (Vadimezan) (25 mg/kg) resulted in widespread necrosis at 24 h, a 9-day growth delay and complete regressions in 50 % mice. Furthermore, co-administration of lenalidomide (100 mg/kg) significantly increased the growth delay to 20 days and the percentage of cures to 83 % [4].


It is reported that DMXAA (Vadimezan) is a multi-inhibitor to several kinases, with most potent effects being on members of the VEGFR (vascular endothelial growth factor receptor) tyrosine kinase family. In zebrafish embryos and HUVECs (human umbilical vein endothelial cells), DMXAA (Vadimezan) blocked the angiogenesis and VEGFR2 signalling [5].
