DMAT (1 μM-2.5 μM) DMAT is more efficient in killing antiestrogen resistant cells than parental antiestrogen sensitive MCF-7 cells. DMAT-induced cell death of antiestrogen resistant cells is mediated by caspases. DMAT inhibits CK2 activity but the inhibition is similar in the three cell lines, MCF-7, TAMR-1 and 182R-6. DMAT has effects on H295R cell proliferation at concentrations of 10 ^-4 and 10 ^-5 mol/Las compared with the control. DMAT (100 μM) significantly increases apoptosis of H295R cells. DMAT (1 nM-1 μM) significantly decreases aldosterone release into supernatants of 72-h H295R cell cultures as compared with the control. DMAT also inhibits PIM1 by a mechanism which is competitive with respect to ATP, and it is a powerful inhibitor of kinases other than CK2.

DMAT application in vivo reduces tumor growth in a xenotransplant model by interference with tumor cell proliferation. Biochemical parameters and histology following DMAT administration revealed no alterations in liver tissue.
