Gene Information

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.

The intercalative acridine derivative 4'-(9-acridinylamino)methanesulfon-m-anisidide (m-AMSA), but not its isomer o-AMSA, is a potent antitumor drug that in mammalian cells stimulates the formation of DNA strand breaks that are characterized by tightly bound proteins. Using purified mammalian DNA topoisomerases, we

Designing ligands targeting G-quadruplex nucleic acid structures and affecting cellular processes is complicated because there are multiple target sequences and some are polymorphic. Further, structure alone does not reveal the driving forces for ligand binding. To know why a ligand

Treatments for refractory glaucoma include trabeculectomy, in which a filtering bleb is created to reduce aqueous pressure. Mitomycin C (MMC) is often used as an adjuvant to reduce post-trabeculectomy bleb scarring and consequent failure. However, scarring sometimes still occurs. Thus
