2013-05-14 · Since the introduction of all-trans retinoic acid (ATRA) and arsenic trioxide (As2O3) for the treatment of acute promyelocytic leukemia (APL), the overall survival rate has improved dramatically. However, relapse/refractory patients showing resistance to ATRA and/or As2O3 are recognized as a clinically significant problem. Genetic mutations resulting in amino acid substitution in the retinoic As showed by Taylor et al. the mechanism through which arsenic trioxide leads to mitotic arrest before cell death induction is still a subject of open intensive research and discussion . Arsenic trioxide has shown substantial efficacy in treating both newly diagnosed and relapsed patients with acute promyelocytic leukemia (APL).

anticancer agents including taxol, doxorubicine, arsenic trioxide, vincristine, and Their mechanisms of action and therapeutic potential are discussed below. Abstract. Arsenic trioxide has shown substantial efficacy in treating both newly diagnosed and relapsed patients with acute promyelocytic leukemia (APL). As a single agent, it induces complete remissions, causing few adverse effects and only minimal myelosuppression.

With the elucidate the mechanism of action of AT. An important study indicated dose-dependent dual effects, with preferential Arsenic trioxide (ATO)‑induced hepatotoxicity limits the therapeutic effect of acute myelogenous leukemia treatment. Magnesium isoglycyrrhizinate (MgIG) is a natural compound extracted from licorice and a hepatoprotective drug used in liver injury. It exhibits anti‑oxidant, anti‑inflammatory and anti‑apoptotic properties. 16 Mechanism of Action 17 The mechanism of action of TRISENOX™ is not completely understood. Arsenic trioxide 18 causes morphological changes and DNA fragmentation characteristic of apoptosis in Two-year event-free survival rates were 97% in the ATRA–arsenic trioxide group and 86% in the ATRA–chemotherapy group (95% confidence interval for the difference, 2 to 22 percentage points; P Mechanisms of action of molecular targeting drugs to APL cells ATRA Wild-type RARais a nuclear hormone receptor that binds to consensus sequence DR5 (ﬁve bases spaced between two AGGTCA motifs) in target gene promoters, normally as heterodimer with retinoid X receptor (RXR) [31–33].

See full prescribing information for TRISENOX. TRISENOX® (arsenic trioxide) injection, for intravenous use Initial U.S. Approval: 2000 WARNING: DIFFERENTIATION SYNDROME, Delia Gutman, Alejo Morales, Jennifer M. McCafferty, Emilio Volz, Tatiana Eguizabal, Kelvin P. Lee, Lawrence H. Boise; Glutathione and Glutathione Utilizing Enzymes Are Key Determinants in the Sensitivity of Myeloma Cells to Arsenic Trioxide as Well as Its Mechanism of Action.. Hedgehog pathway inhibitors are small molecules that inhibit the activity of a component of the Hedgehog signaling pathway.Due to the role of aberrant Hedgehog signaling in tumor progression and cancer stem cell maintenance across cancer types, inhibition of the Hedgehog signaling pathway can be a useful strategy for restricting tumor growth and for preventing the recurrence of the disease Although the precise mechanism of arsenic trioxide action is unknown, a variety of in vitro studies suggest that several mechanisms may contribute to its effectiveness in vivo . As described above, these mechanisms include induction of apoptosis, partial cellular differentiation, degradation of specific APL fusion transcripts, antiproliferation, and inhibition of angiogenesis.
N2 - Background: The ancient drug, arsenic, has remarkable efficacy in the treatment of relapsed acute promyelocytic leukemia (APL) and this success has led to exploration of its use in other malignancies.

An orally bioavailable capsule formulation of the inorganic toxic compound arsenic trioxide (As2O3), with potential antineoplastic activity. Although the mechanism of action (MoA) of As2O3 is not well understood, upon oral administration of ORH 2014, As2O3 appears to bind to DNA, prevent DNA synthesis, and cause DNA fragmentation, which leads to an induction of apoptosis in proliferating cells Arsenic trioxide; Mechanism of action.

Arsenic trioxide also causes damage or degradation of the fusion protein promyelocytic leukemia (PML)-retinoic acid receptor (RAR mechanism of action of arsenic trioxide is not completely understood. Arsenic trioxide Mylan is a generic of Trisenox, which has been authorised in the EU since 5 March 2002. Since Arsenic trioxide Mylan is administered intravenously and is 100% bioavailable, a bioequivalence study versus the reference product Trisenox was not required.

21 The exact mechanism of the action of arsenic is not known, but several hypotheses have been proposed. At a biochemical level, inorganic arsenic in the pentavalent state may replace phosphate in several reactions. In the trivalent state, inorganic and organic (methylated) arsenic may react with critical thiols in proteins and inhibit their activity. 2020-09-24 · Arsenic trioxide has shown a strong anti-tumor effect with little toxicity when used in the treatment of acute promyelocytic leukemia (APL). An effect on glioma has also been shown. Its mechanisms include regulation of apoptosis and autophagy; promotion of the intracellular production of reactive oxygen species, causing oxidative damage; and inhibition of tumor stem cells.
