Popis

General description

A cell-permeable, non-toxic pyridineisothiazolone compound that acts as a potent, reversible, and ATP-competitive inhibitor of human Thymidylate kinase (TMPK) (IC₅₀ = 610 nM; K_i = 180 nM). Does not affect the activity of Thymidine kinase 1 (TK1) (IC₅₀ >10 µM). Its action appears to involve blocking the interaction of Mg²⁺ with Asp¹⁵ in the catalytic domain. Shown to specifically reduce dTTP (deoxythymidine triphosphate) by 30 to 40% in HCT-116 p53^-/- cells, without affecting dATP, dCTP, and dGTP levels. Significantly increases (3 to 35 fold) the sensitivity of a variety of tumor cell lines to doxorubicin (>Cat. No. 324380), and shrinks tumor size in HCT-116 p53^-/- xenografted mouse model (doxorubicin, 1.25 mg/kg twice a week, i.p.; YMU1, 5 mg/kg thrice a week, i.p.).
