Abstract:We previously reported the discovery of XB05, a synthetic small molecule with antiproliferative activity. XB05 was found to be a strong inhibitor of DNMT1 activity in cell-free and cell-based assays. However, screening in the NCI 60 tumor cell lines and analysis using COMPARE indicated a novel mechanism of action for XB05, different from standard demethylating agents such as 5-azacytidine (azaC) and decitabine. Here, we report on new research to further characterize XB05 activity. We have examined the effects … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
