thymidylate synthase inhibitor CX1106

A thymidylate synthase (TS) inhibitor with potential antineoplastic activity. Upon administration, TS inhibitor CX1106 binds to and inhibits TS. This reduces thymine nucleotide synthesis, inhibits DNA synthesis and cell division, causes DNA damage and leads to tumor cell apoptosis. TS catalyzes the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP), an essential precursor for DNA synthesis, and plays a key role in cell growth and division.
