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.

General description

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

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

The bisdioxopiperazines ICRF-187 (dexrazoxane), ICRF-193, and ICRF-154 are catalytic noncleavable complex-forming inhibitors of DNA topoisomerase II that do not produce protein-linked DNA strand breaks. In this study, we showed that bisdioxopiperazines induced erythroid differentiation, inhibited human leukemia K562 cell growth

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

As many antitumor drugs can kill tumors through the induction of apoptosis, the effect of these drugs presumably would be enhanced if they were used in combination with other drugs that interact with apoptotic processes. To clarify the biological events
DNA topoisomerase II is dispensable for oocyte meiotic resumption but is essential for meiotic chromosome condensation and separation in mice
