C-1311 is an imidazoacridinone analog. It is a next-generation investigational anticancer drug. It is an antitumor inhibitor of topoisomerase II and FMS-like tyrosine kinase 3 receptor. It was evaluated in phase I and II clinical trials for the treatment of various types of tumors. Mild treatment-related adverse events were thrombocytopenia, anemia, nausea, vomiting and diarrhea. Serious adverse event is neutropenia.

In Vivo Use Guide

The initial dose was 480 mg/m2, 1 hr IV infusion on d 1, 8, and 15 of a 28 day cycle.

Route of Administration: Intravenous

In Vitro Use Guide

Acute treatments (3 h) of the a human tumour line (HeLa S3) revealed that cells exposed to C-1311 levels, which first induced persistent G2 arrest (0.5 ug/ml), subsequently died from this compartment, while doses exceeding these levels (1.0 ug/ml), paradoxically, did not cause the same extensive cell death.
