nsc-112907 - Uses and synthesis methods
Target
cytidine deaminase (CDA)
in vitro studies
Tetrahydrouridine (THU) is a specific inhibitor of cytidine deaminase (CDA) which can suppress deamination in the catabolism of cytotoxic deoxycytidine analogues like ara-C and Gemcitabine. To test how Tetrahydrouridine affects the Gemcitabine-mediated anti-neoplastic effect on pancreatic and lung carcinoma cells, a combination therapy is performed. As expected, high CDA expression in BxPC-3 and H441 results in improved Gemcitabine sensitivity after a 100 µM Tetrahydrouridine treatment. The sensitivity of BxPC-3 and H441 cell lines increases by as much as approximately 2.1 and 4.4 fold respectively. On the other hand, MIAPaCa-2 and H1299 cells unexpectedly become more sensitive to Gemcitabine with low CDA expression. MIAPaCa-2 and H1299 cells show a change in IC 50 of 2.2 and 2.3 fold respectively. However, Panc-1 and H322 cells do not show significant changes in drug sensitivity. These data suggested that Tetrahydrouridine can sensitize some pancreatic and lung carcinoma cells to Gemcitabine-induced cell death regardless of CDA expression levels. Tetrahydrouridine inhibits S-phase without apoptosis.
In vivo studies
Administration of 167 mg/kg Tetrahydrouridine (THU) followed by 1.0 mg/kg DAC results in death in one male and eight females. Animals surviving to scheduled termination are generally asymptomatic with no treatment related effects observed in body weights, food consumption, clinical chemistry and urinalysis for a treatment up to 1.0 mg/kg DAC in combination with 167 mg/kg Tetrahydrouridine in animals.
