Amsidyl - General Information

Aminoacridine derivative that is a potent intercalating antineoplastic agent. It is effective in the treatment of acute leukemias and malignant lymphomas, but has poor activity in the treatment of solid tumors. It is frequently used in combination with other antineoplastic agents in chemotherapy protocols. It produces consistent but acceptable myelosuppression and cardiotoxic effects.

Amsidyl Indication

For treatment of acute myeloid leukaemia.

Mechanism Of Action
Amsidyl binds to DNA through intercalation and external binding. It has a base specificity for A-T pairs. Rapidly dividing cells are two to four times more sensitive to amsacrine than are resting cells. Amsidyl appears to cleave DNA by inducing double stranded breaks. Amsidyl also targets and inhibits topoisomerase II. Cytotoxicity is greatest during the S phase of the cell cycle when topoisomerase levels are at a maximum.
