dna polymerase θ

ART558 is a potent, selective, low molecular weight, allosteric DNA polymerase activity of Polθ inhibitor (IC50=7.9 nM). ART558 can be used for the research of cancer.

DNA polymerase-IN-1, a DNA polymerase inhibitor, exhibited antiproliferative activity against tumor cells with a half-inhibitory concentration (IC50) of 20.7 μM. DNA polymerase-IN-1 inhibited Taq DNA polymerase with an IC50 of less than 250 μM. DNA polymerase-IN-1 was shown to inhibit Taq DNA polymerase by RT- DNA polymerase-IN-1 showed antiretroviral activity in vitro by RT-PCR assay and can be used to study oxidative damage and colorectal cancer.

ART899, a derivative of ART558, is a potent and specific conformational inhibitor of DNA polymerase θ (Polθ). It specifically inhibits the MMEJ activity of Polθ with an IC50 of 180 nM. Additionally, ART899 selectively enhances the radiosensitivity of tumor cells and possesses a strong independent antitumor effect on cancer cells.

ART812 is an orally active inhibitor of DNA polymerase Polθ, possessing an IC50 value of 7.6 nM. Additionally, ART812 exhibits a cell-based microhomology-mediated end joining (MMEJ) IC50 value of 240 nM.

Polθ-IN-7 (example 12) is an inhibitor of DNA polymerase θ (Polθ) with a Ki of 1.27 nM.
