Guadecitabine is a novel hypomethylating dinucleotide of decitabine and deoxyguanosine that is resistant to degradation by cytidine deaminase. Guadecitabine Sodium is the easily dissolved form of Guadecitabine[1].
Guadecitabine (0.1, 0.3, 1, 5µM, 48h) increased sensitivity to cisplatin for both the parental and the resistant A2780 cells. Although among other ovarian cancer cell lines, the parental A2780- cisplatin resistant cells is considered to be cisplatin “sensitive”, it has a relatively high IC50 for the drug[2].
Guadecitabine (50nM-2µM, 24h) pretreatment synergistically interacted with ASTX660 to induce cell death in five AML cell lines (MOLM-13, ML-2, MV4-11, PLB-985, KG-1) with various genetic backgrounds and representing different AML subtypes [3].
Tumor-bearing immune-deficient mice were exposed subcutaneously to Guadecitabine at doses of 3, 6.1, or 10 mg/kg, daily for 5 days, with tumors harvested on day 7. Most mice treated on the 5 day schedule with 10mg/kg/day Guadecitabine died; all mice treated with 6.1mg/kg/day Guadecitabine developed gastrointestinal toxicity. Minimal toxicity was observed in mice treated with 3mg/kg/day. Guadecitabine treatment caused hypomethylation of LINE-1 and NY-ESO-1 at all doses[4].
