Uses
ICRF-193 has been used as a topoisomerase II (TOP2) inhibitor to treat mouse oocytes to investigate the role of TOP2 in meiosis.
Definition
ChEBI: ICRF-193 is an N-alkylpiperazine that is butane which is substituted by a 3,5-dioxopiperazin-1-yl group at positions 2 and 3. The meso isomer. It has a role as an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, an apoptosis inducer and an antineoplastic agent.
General Description
ICRF-193 is a bisdiopiperazine derivative. It inhibits topoisomerase II by forming a non-cleavable?complex.
Biochem/physiol Actions
ICRF-193 induces a G2 checkpoint that is associated with an ATR-dependent inhibition of polo-like kinase 1 (plk1) activity and a decrease in cyclin B1 phosphorylation. Induces apoptosis in several cell lines including K562 and Molt-4 cells., ICRF-193 is a topoisomerase II inhibitor, more potent against topoisomerase II-β than topoisomerase II-α, and may in addition cause DNA strand breaks.
