| In Vitro | In vitro activity: Thioguanine incorporation alters the DNA cleavage induced by topoisomerase II in the presence and absence of etoposide. 6-Thioguanine alters the structure and lowers the thermal stability of duplex DNA, but duplex DNA can be formed in the presence of 6SG. 6-Thioguanine induced apopotosis is similarly observed in both mismatch repair-proficient and -deficient HCT116 and HeLa cells. Thioguanine integrates into DNA and unlike the canonical DNA bases, it is a strong UVA chromophore with an absorbance maximum at 342 nm. 6-Thioguanine is a photosensitizer and a source of reactive oxygen species. In canine lymphoma cells, Thioguanine significantly decreases DNMT1 protein and global DNA methylation. Cell Assay: Treatments consists of 3 thiopurines (azathioprine, 6-mercaptopurine, and 6-Thioguanine (Thioguanine)) at each of 6 concentrations (0.468, 0.937, 1.875, 3.750, 7.500, and 15.000 μM). Each thiopurinee is dissolved in DMSO solution to achieve a concentration of 10 mg/mL. Sterile filtered maintenance medium is used to further dilute each thiopurine solution to each of the 6 treatment concentrations. Twenty-four hours after the hepatocytes are plated on 96-well culture |

| In Vivo | Thioguanine is as efficient as a PARP inhibitor in selectively killing BRCA2-defective tumors in a xenograft model. 6-Thioguanine efficiently kills such BRCA1-defective PARP inhibitor-resistant tumors. 6-Thioguanine could kill cells and tumors that have gained resistance to PARP inhibitors or cisplatin through genetic reversion of the BRCA2 gene |
