TAS1553 is a potent, orally active protein-protein interaction (PPI) inhibitor with an IC50 values of 0.0396 μM. TAS1553 inhibits DNA replication and reduces intracellular dATP pool. TAS1553 induces apoptosis. TAS1553 can be used for cancer research[1].
TAS1553 (0.001-1 μM) inhibits the enzymatic activity of RNR in a dose-dependent manner[1].
TAS1553 (3 d) has anti-proliferative activity against both solid and hematological human cancer cell lines and the GI50 values ranged from 0.228 to 4.15 μM[1].
TAS1553 (1-10 μM; 0-2 h; HCC38 and MV-4-11 cells) reduces intracellular dATP pool in a dose- and time-dependent manner, which is a critical metabolite for DNA replication[1].
TAS1553 (0-10 μM; 0-24 h; HCC38 and MV-4-11 cells) induces the replication stress and apoptosis in a dose- and time-dependent manner[1].

TAS1553, a small molecule subunit interaction inhibitor of ribonucleotide reductase, exhibits antitumor activity by causing DNA replication stress
Commun Biol 2022 Jun 9;5(1):571.PMID:35681099DOI:PMC9184620
Ribonucleotide reductase (RNR) is composed of two non-identical subunits, R1 and R2, and plays a crucial role in balancing the cellular dNTP pool, establishing it as an attractive cancer target. Herein, we report the discovery of a highly potent and selective small-molecule inhibitor, TAS1553, targeting protein-protein interaction between R1 and R2. TAS1553 is also expected to demonstrate superior selectivity because it does not directly target free radical or a substrate binding site. TAS1553 has shown antiproliferative activity in human cancer cell lines, dramatically reducing the intracellular dATP pool and causing DNA replication stress. Furthermore, we identified SLFN11 as a biomarker that predicts the cytotoxic effect of TAS1553. Oral administration of TAS1553 demonstrated robust antitumor efficacy against both hematological and solid cancer xenograft tumors and also provided a significant survival benefit in an acute myelogenous leukemia model. Our findings strongly support the evaluation of TAS1553 in clinical trials.
