MedKoo CAT#: 201510

CAS#: 138154-39-9 (free base)

Description: Symadex, also known as imidazoacridone; XLS-002 and C-1311, is a member of the novel imidazoacridinone family of anticancer agents. Imidazoacridone has shown activity in experimental tumour models both in vitro and in nude mice. C-1311 at the EC(99) dose delayed progression of cells through the S phase which was followed by G2 arrest. C-1311 does not induce rapid apoptosis in HT-29 cells, instead drug exposure leads to prolonged G2 arrest followed by G2 to M transit and cell death during mitosis in the process of mitotic catastrophe.
