01
Overview
TS-2 is a small molecule inhibitor of the terminal uridyltransferases (TUTases) ZCCHC11 (also known as TUT4 or TENT3A) and ZCCHC6 (also known as TUT7 or TENT3B). Developed by Twentyeight-Seven Therapeutics, TS-2 is the weakly active enantiomer of the more potent lead compound TS-1. In preclinical research, TS-2 demonstrated significantly lower biochemical potency compared to TS-1, with IC50 values of 0.15 μM for ZCCHC11 and 1.8 μM for ZCCHC6. It is primarily utilized as a pharmacological control to validate the therapeutic potential of TUTase inhibition in suppressing glioblastoma cell proliferation and modulating RNA uridylation.
