Daun02 is a prodrug, which is converted by β-galactosidase to Daunorubicin, which has been shown to reduce calcium ion (Ca 2+ )-dependent action potentials in neuroblastoma cells. Daunorubicin is a topoisomerase inhibitor. Daun02 is a good substrate for β-galactosidase (β-gal). The concentration of Daun02 producing 50% (EC 50 ) decrease in cell viability is 0.5 μM, 1.5 μM, and 3.5 μM for T47-D, Panc02, and MCF-7, respectively.
Daun02 is a good substrate for β-gal with K m and V max values of 0.37 mM and 8.6 μmol/min/mg protein. At a concentration of 10 -5 M, Daun02 is 79% bound to plasma protein compares to 94% for Daunomycin.
