Application

Amsacrine hydrochloride has been used:
  • as a topoisomerase poison in bacteriophage T4 topoisomerase assay
  • as a topoisomerase inhibitor in Drosophila cell line, Kc167
  • as an antileukemia drug to test its effect on p53 transcriptional activity in tumor xenografts
  • as a topoisomerase II poison in dose-response assays in C elegans

Biochem/physiol Actions

Amsacrine (m-AMSA) is a derivative of acridine and an antileukemia drug. It is an anticancer drug with antineoplastic activity that targets topoisomerase II. AMSA is an apoptosis inducer and favors the accumulation of double-stranded breaks (DSBs). It also inhibits the expression of matrix metallopeptidase 2 (MMP-2) and MMP-9 expression in leukemia cells by generating reactive oxygen species (ROS). AMSA serves as an adjuvant in trabeculectomy surgery.
Amsacrine hydrochloride is a DNA topoisomerase II inhibitor.

Topoisomerase (topo) IIα and IIβ maintain genome stability and are targets for anti-tumor drugs. In this study, we demonstrate that the decatenation checkpoint is regulated, not only by topo IIα, as previously reported, but also by topo IIβ. The decatenation

CP-31398 activates wild-type p53 by a novel mechanism that does not involve phosphorylation of the amino-terminus of p53 and disassociation of MDM2. To identify more potent CP-31398-like p53 activators, we synthesized 4 acridine derivatives with a similar structure to CP-31398.

Topoisomerase II is the only enzyme able to cleave and religate double-stranded DNA; this makes it essential for many vital functions during normal cell growth. Increased expression of topoisomerase II is a common occurrence in neoplasia, and different topoisomerase II

Amsacrine (4'-(9-acridinylamino)methanesulphon-m-anisidide) is an antileukemic drug which inhibits topoisomerase II (topo II) enzymes. We studied effects of two concentrations of amsacrine on the GM10115A cell line. This is a Chinese hamster line containing a single human chromosome 4, which can

9-[(3-chloro)phenylamine]-2-[3-(diethylamine)propylamine]thiazolo[5,4-b]quinolone (D3ClP) is a bioisostere of N-(4-(acridin-9-ylamino)-3-methoxyphenyl)methanesulfonamide (m-AMSA) a DNA topoisomerase II inhibitor with proven cytotoxic activity and known to induce DNA damage and apoptotic cell death in K562 cells. However, recent evidence is not consistent with DNA topoisomerase II
