To identify potential therapeutic targets and preclinical drug candidates for the treatment of ovarian cancer, researchers led by Tan Li from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences have developed novel small molecule inhibitors of CPSF3, a key module of the cleavage and polyadenylation specificity factor (CPSF) complex that catalyzes pre-mRNA splicing and regulates transcription termination.
This work was published in Science Advances on Nov. 22.

In treating ovarian cancer, surgery and systemic chemotherapy can modestly improve the survival rate, while targeted therapies with PARP inhibitors are effective in a limited number of ovarian cancer patients.
