Biological Activity
ART812 is a DNA polymerase Polθ inhibitor with an IC50 value of 7.6 nM. ART812 has an IC50 value of 240 nM for cell based microhomology-mediated end joining (MMEJ)[1][2].
In Vitro
ART812 (0-40 μM) elicits Polθ inhibitor sensitivity in MDA-MB-436 SHLD2 knockout cells[1].
In Vivo
ART812 (100 mg/kg; p.o. daily for 76 days) shows significant tumour inhibition in rats bearing established MDA-MB-436 BRCA1/SHLD2 defective tumours (volume 250-350 mm3)[1].
Target
Polθ:7.6 nM (IC50)
