RP-6685 is a potent, selective and orally active DNA polymerase theta (Polθ) inhibitor with an IC50 value of 5.8 nM (PicoGreen assay). RP-6685 shows antitumor efficacy in mouse tumor xenograft model[1].
RP-6685 is extremely potent with an IC50 of 550 pM against the pol activity of full-length Polθ and inactive on the ATPase activity[1].
RP-6685 inhibits Polθ in HEK293 LIG4-/- cellswith an IC50 of 0.94 μM[1].
RP-6685 (80 mg/kg; p.o.; BID for 21 days) exhibits potent antitumor efficacy in BRCA2-deficient HCT116 mice[1].

Identification of RP-6685, an Orally Bioavailable Compound that Inhibits the DNA Polymerase Activity of Polθ
J Med Chem 2022 Oct 13;65(19):13198-13215.PMID:36126059DOI:10.1021/acs.jmedchem.2c00998
DNA polymerase theta (Polθ) is an attractive synthetic lethal target for drug discovery, predicted to be efficacious against breast and ovarian cancers harboring BRCA-mutant alleles. Here, we describe our hit-to-lead efforts in search of a selective inhibitor of human Polθ (encoded by POLQ). A high-throughput screening campaign of 350,000 compounds identified an 11 micromolar hit, giving rise to the N2-substituted fused pyrazolo series, which was validated by biophysical methods. Structure-based drug design efforts along with optimization of cellular potency and ADME ultimately led to the identification of RP-6685: a potent, selective, and orally bioavailable Polθ inhibitor that showed in vivo efficacy in an HCT116 BRCA2-/- mouse tumor xenograft model.
