NP-004255 (NP004255, Corilagin) is a small molecule binds specifically to DNA repair protein RAD52 and disrupts the RAD52-ssDNA interaction, inhibits ssDNA binding with IC50 of 1.5 uM.




BAY-707 is a highly potent, selective and substrate-competitive inhibitor of MTH1 (NUDT1) with IC50 of 2.3 nM; demonstrates high selectivity in an in-house kinase panel, and shows an overall favorable physicochemical profile and in vitro pharmacokinetic properties with high metabolic stability; demonstrates a superior cellular target engagement with an EC50 of 7.6 nM compared with TH588, increases the cellular thermal stabilization of MTH1 with no effect on the expression of MTH2, OGG1, and MUTYH; shows a clear lack of in vitro or in vivo anticancer efficacy either in mono- or in combination therapies in vivo.




HUHS-015 (HUHS015) is a potent, orally active prostate cancer antigen-1 (PCA-1/ALKBH3) inhibitor with IC50 of 0.67 uM; significantly suppresses the growth of DU145 cells in vitro and in a mouse xenograft model.



1005129-80-5 A12B4C3 (hPNKP inhibitor A12B4C3) is a specific, noncompetitive inhibitor of the human DNA repair enzyme polynucleotide kinase/phosphatase (hPNKP) with C50 of 60 nM, displays no inhibition of calcineurin and protein phosphatase-1 or APTX; A12B4C3 enhanced the radiosensitivity of human A549 lung carcinoma and MDA-MB-231 breast adenocarcinoma cells, failed to increase the radiosensitivity of the hPNKP-depleted cells; A12B4C3 also inhibits the repair of DNA single and double strand breaks following exposure of cells to ionizing radiation, but does not inhibit two other key strand-break repair enzymes, DNA polymerase beta or DNA ligase III,


1417653-96-3 MLAF50 is the first small-molecule inhibitor of the REV1 UBM2-Ubiquitin interaction, directly binds to REV1 UBM2 with Kd of 37 uM in SPR assays; inhibits chromatin localization of REV1 in cells after damaging DNA; binds to the same residues of REV1 UBM2 that interact with ubiquitin, indicating that MLAF50 can compete with the REV1 UBM2-ubiquitin interaction orthosterically.


1430213-30-1 ML216 (CID49852229) is a potent, selective inhibitor of DNA unwinding activity of BLM (Bloom's syndrome protein) with IC50 of 2.98 and 0.97 uM for full length BLM and BLM636-1298, respectively; weak inhibits WRN helicase (IC50=12.6 uM) and does not inhibit RecQ1, RecQ5 and UrvD (IC50>50 uM); disrupts BLM’s binding to DNA, rather than being an inhibitor of ATP binding by BLM, the inhibition of ssDNA-dependent ATPase activity with Ki of 1.76 uM, shows cell-based activity and can induce sister chromatid exchanges, enhances the toxicity of aphidicolin, and exerts antiproliferative activity in cells expressing BLM.


313526-24-8 IBR2 is a novel small molecule RAD51 inhibitor that specifically binds to RAD51 and disrupts the BRC repeats of BRCA2/RAD51 interaction with IC50 of 0.11 uM; disrupts RAD51 multimerization and inhibits RAD51-mediated HR repair, reduces RAD51 protein levels via proteasome-mediated degradation; inhibits cell growth and induces apoptosis in imatinib-resistant T315I-Ba/F3 cells; significantly prolongs animal survival in a murine imatinib-resistant CML model bearing the T315I Bcr-abl mutation.
