TAS-114 | CAS#1198221-21-4 | dUTPase Inhibitor

MedKoo Cat#: 206624 | Name: TAS-114

Description:

WARNING: This product is for research use only, not for human or veterinary use.

TAS-114 is a first-in-class oral deoxyuridine triphosphatase (dUTPase) inhibitor, which acts as a modulator of the pyrimidine nucleotide metabolic pathway. dUTPase may protect cancer cells from aberrant base mediated cytotoxicity during thymidylate synthase (TS) inhibition, and its overexpression is associated with resistance to TS inhibitors.
