Briciclib (ON 014185) is a eukaryotic translation initiation factor 4E (eIF4E) inhibitor. Briciclib exhibits broad-spectrum anti-cancer activity, including in mantle cell leukemia, breast cancer, gastric cancer, and esophageal cancer cells. Briciclib reduces the expression of cyclin D1 and c-Myc, and enhances the expression of P53 and Cleaved Caspase 3 pro-apoptotic proteins. Briciclib can be used for the study of hematological system tumors and solid tumors[1].
