General description

ICRF-193 is a bisdiopiperazine derivative. It inhibits topoisomerase II by forming a non-cleavable complex.

Application

ICRF-193 has been used as a topoisomerase II (TOP2) inhibitor to treat mouse oocytes to investigate the role of TOP2 in meiosis.

Biochem/physiol Actions

ICRF-193 helps in the enhancement of cell cycle without chromosome segregation. It is considered as an important drug for chemo-differentiation therapy against acute promyelocytic leukemia (APL). ICRF-193 serves as an inducer of differentiation between anticancer drugs.
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.

ICRF-193, a catalytic inhibitor of DNA topoisomerase II, delays the cell cycle progression from metaphase, but not from anaphase to the G1 phase in mammalian cells

The bis-dioxopiperazine ICRF-193 has long time been considered as a pure topoisomerase II catalytic inhibitor able to exert its inhibitory effect on the enzyme without stabilization of the so-called cleavable complex formed by DNA covalently bound to topoisomerase II. In

Antineoplastic bis(dioxopiperazine)s, such as meso-2,3-bis(2,6-dioxopiperazin-4-yl)butane (ICRF-193), are widely believed to be only catalytic inhibitors of topoisomerase II. However, topoisomerase inhibitors have little or no antineoplastic activity unless they are topoisomerase poisons, a special subclass of topoisomerase-targeting drugs that stabilize topoisomerase-DNA
Sílvia Dyson et al.
The EMBO journal, 40(1), e105393-e105393 (2020-11-07)
The juxtaposition of intracellular DNA segments, together with the DNA-passage activity of topoisomerase II, leads to the formation of DNA knots and interlinks, which jeopardize chromatin structure and gene expression. Recent studies in budding yeast have shown that some mechanism
