What do you think of the answers? Arsenic (III) oxide react with water As 2 O 3 + 3H 2 O ⇄ 2H 3 AsO 3 [ Check the balance ] Arsenic (III) oxide react with water to produce orthoarsenous acid. Lu J, Hu S, Wang W, Li J, Dong Z, Zhou J, Hai X. Toxicol Sci. Favourite answer. Arsenic in As2O3 is oxidized from +3 to +5, and oxygen in H2O2 is reduced from -1 to -2. Four patients received single‐agent As2O3 for 1 consolidation course (n = 1 patient), 3 consolidation courses (n = 2 patients), and 4 consolidation courses (n = 1 patient). This glassy, white, deliquescent solid is relatively unstable, consistent with the rarity of the As(V) oxidation state. Studies evaluating the role of As2O3 in this setting, including investigation of the combination of As2O3 and ATRA, currently are ongoing. The starting dose of As2O3 was 0.15 mg/kg per day intravenously until patients achieved a CR or to a maximum of 60 days. Hepatotoxicity From Arsenic Trioxide for Pediatric Acute Promyelocytic Leukemia. initially reported on 15 patients with recurrent APL who were treated with As2O3. Answer Save. Overall survival of 12 patients who were treated with arsenic trioxide for recurrent acute promyelocytic leukemia. 4 years ago. Find another reaction. Twelve patients with recurrent APL after treatment with ATRA‐based therapy were treated with As2O3. Arsenic (+3 oxidation state) methyltransferase (AS3MT) is a key enzyme responsible for arsenic metabolism in humans, which facilitates conversion of arsenic trioxide (As2O3) to more reactive metabolites such as monomethylarsonous acid (MMAIII) and dimethylarsinous acid (DMAIII). Arsenic trioxide, sold under the brand name Trisenox among others, is an inorganic compound and medication. Ob­tain­ing the pure sub­stance and its chem­i­cal prop­er­ties. 0 0. bala. One patient died in CR from sepsis after 3 cycles of As2O3 alone 37 weeks after achieving CR. 2014 Jul;132:156-67. doi: 10.1016/j.envres.2014.03.012. Keywords: If you do not receive an email within 10 minutes, your email address may not be registered, These therapies may induce remissions in up to 70–80%1 but carry significant morbidity and mortality. Fourteen patients (82%) achieved a CR with a median follow‐up of 6 months, and 6 patients were still in remission.5 In a different approach, L‐ATRA was used as salvage therapy in six patients who had developed recurrent disease after therapy with ATRA. 9 years ago +3. Arsenic is in group 15, it can lose 5 valence electrons or gain 3 valence electrons to achieve the octet. From the intensity of the white-line feature and the concentration of As species, calibration curves showing a … Arsenic trioxide for management of acute promyelocytic leukemia: current evidence on its role in front-line therapy and recurrent disease. Non-Coding RNAs as Molecular Targets of Resveratrol Underlying Its Anticancer Effects. Sixteen patients (84%) achieved a CR, and 6 patients had negative PCR results at the time of hematologic CR; 14 patients had negative PCR results 2–4 months after hematologic CR.15 Thus, because the experience with As2O3 to date relates to patients with recurrent APL, the rate of molecular remissions at the time of CR is very favorable. Impact of arsenic trioxide in the treatment of acute promyelocytic leukemia. Agusa T, Fujihara J, Takeshita H, Iwata H. Int J Mol Sci. Acute promyelocytic leukemia: from highly fatal to highly curable. During therapy, patients were monitored with CBCs, SMA‐12, and coagulation profiles until the completion of therapy. The median time to achieve hematologic CR was 52 days (range, 27–75 days) (Table 2). The dose was diluted in 250 cc of 5% dextrose and was administered over 2 hours. Lv 4. As2S3: (arsenic oxidation state) Let oxidation no of arsenic be x. Remission duration was measured from the date when CR was achieved to the date of clinical recurrence. Chem., Sect. All-trans retinoic acid/As2O3 combination yields a high quality remission and survival in newly diagnosed acute promyelocytic leukemia. Arsenic trioxide’s content is 99.94%, extraction yield can reach to 98.92%. Picture of reaction: Сoding to search: As2O3 + 6 NaOH = 2 Na3AsO3 + 3 H2O. reported 8 of 11 tested patients in molecular CR after two courses of therapy. Yasen Maimaitiyiming, Chao Wang, Shi Xu, Khairul Islam, Ye Jia Chen, Chang Yang, Qian Qian Wang, Hua Naranmandura, Role of arsenic (+3 oxidation state) methyltransferase in arsenic mediated APL treatment: an in vitro investigation , Metallomics, 10.1039/C8MT00057C, 10, 6, (828-837), (2018). One of those patients required discontinuation of therapy and had a partial improvement of symptoms after therapy was discontinued. A CR was defined using conventional criteria, including cellular bone marrow blasts and abnormal promyelocytes ≤ 5%; with an absolute neutrophil count ≥ 1.0 × 109/L and a platelet count ≥ 100 × 109/L. Polymorphisms in arsenic (+ 3 oxidation state) methyltransferase (AS3MT) have been shown to be related to interindividual variations in arsenic metabolism and to influence adverse health effects in acute promyelocytic leukemia (APL) patients treated with arsenic trioxide (As2O3). The results showed that APL patients who developed hyperleukocytosis had a higher plasma iAs%, but a lower MMA% and PMI than those who did not develop hyperleukocytosis during As2O3 treatment. © 2003 American Cancer Society. As2O3 appears to be a safe and effective agent for the treatment of patients with APL. Have all-trans retinoic acid and arsenic trioxide replaced all-trans retinoic acid and anthracyclines in APL as standard of care. Before ATRA was used widely as frontline therapy, Cortes et al. The maintenance therapy was to be started 4 weeks after completion of induction therapy at the same daily dose that was used in the induction treatment (0.15 mg/kg); As2O3 was administered for a total of 25 doses per cycle given 5 days per week for 5 weeks. Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis. Mutant Transcription Factors and Tyrosine Kinases as Therapeutic Targets for Leukemias: From Acute Promyelocytic Leukemia to Chronic Myeloid Leukemia and Beyond. Treatment concepts of acute promyelocytic leukemia. Two patients received no additional As2O3 in maintenance and were consolidated with idarubicin and ATRA for three courses and six courses, respectively (Table 3). Arsenic (As) is a semimetal that can exist in inorganic, organic, or gaseous forms in nature. More common, and far more important commercially, is arsenic(III) oxide (As 2 O 3 ). Long-term outcome of acute promyelocytic leukemia treated with all- All 12 patients achieved CR. NLM 2018 Nov 1;166(1):219-227. doi: 10.1093/toxsci/kfy210. All patients received additional therapy after achieving a CR (Table 3). and you may need to create a new Wiley Online Library account. Plasma arsenic methylation metabolism capacity was evaluated by the percentage of inorganic arsenic (iAs), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), primary methylation index (PMI, MMA/iAs), and secondary methylation index (SMI, DMA/MMA). Acute promyelocytic leukemia (APL) is characterized by the presence of a translocation, t(15; 17), that fuses the gene encoding for the nuclear receptor for retinoic acid (RARα) to the PML gene (PML‐RARα).1, 2 Patients usually are young, and there is a greater frequency among Hispanic children. Optimizing treatment for elderly patients with acute promyelocytic leukemia: is it time to replace chemotherapy with all-trans retinoic acid and arsenic trioxide?. Once again, arsenic has -3 oxidation state in arsenides or intermetallic compounds. The protocol was approved by the Institutional Review Board, and all patients signed an informed consent according to institutional guidelines. The reports by Unnikrishnan et al.31 and Westervelt et al.32 did not use the formulation of As2O3 that is available commercially that was used in the current study, raising the possibility that this may not be a direct complication from As2O3. The Effect of Arsenic Trioxide on All-trans Retinoic Acid Binding to Human Serum Albumin. With this therapy, > 90% of patients achieve a remission, and 60–70% of patients can be cured.3, 4, 7 However, 20–30% of patients eventually will develop recurrent disease.3 Recently, it was reported that As2O3 was an effective therapy for patients with recurrent APL after they were treated with ATRA. Therapy could be administered on an inpatient or outpatient basis. The primary objective was to document the efficacy and safety of As2O3. Therefore, gallium arsenide oxidation states are +3 for Ga and -3 for As. Two patients required a dose reduction to 0.11 mg/kg per day after 2 weeks of therapy due to fluid retention and severe epigastric pain (n = 1 patient) and due to chest pain (n = 1 patient). The third patient developed recurrent disease and died from leukemia 73 weeks after the initial response, having received three maintenance courses of As2O3. Thermodynamic properties of substances The solubility of the substances Periodic table of elements. Acute promyelocytic leukemia: What is the new standard of care?. Epub 2019 Jul 19. Survival was measured from the time of treatment until death. of As = + 3. In its turn arsenic possible oxidation states are -3, +3 and +5. Molecular Monitoring as a Path to Cure Acute Promyelocytic Leukemia. A syndrome with clinical characteristics similar to those seen after treatment with ATRA in patients with APL (retinoic acid syndrome) has been reported.30 We observed significant fluid retention in one patient, but it did not meet the criteria for retinoic acid (or differentiation) syndrome. AS3MT Polymorphisms, Arsenic Metabolism, and the Hematological and Biochemical Values in APL Patients Treated with Arsenic Trioxide. Arsenic Trioxide: New Clinical Experience With an Old Medication in Hematologic Malignancies. Demyelinating Diseases of the Peripheral Nerves. Since there are two arsenic atoms and three sulfur atoms with -2 oxidation state: 2 (x)+3 (-2)=0, so 2x-6=0, 2x=6, x=+3. The speciation of arsenic (As) in plant samples was investigated using the mixtures As2S3/As2O5, As2S3/As2O3, or As2O3/As2O5. American Journal of Health-System Pharmacy.

Differential cytotoxic effects of arsenic compounds in human acute promyelocytic leukemia cells. Patients could not receive any other cytotoxic chemotherapy during induction therapy. +1, +2, +3, +4, or +5? Myeloid Leukemia, Myelodysplasia, and Myeloproliferative Disease in Children. Economic evaluation of arsenic trioxide compared to all‐trans retinoic acid + conventional chemotherapy for treatment of relapsed acute promyelocytic leukemia in Canada. Arsenic(III) oxide react with sodium hydroxide to produce sodium orthoarsenite and water. The patient who presented in third recurrence was treated originally with ATRA, achieved a CR, and developed a recurrence after 168 weeks. At present the main method for ob­tain­ing ar­senic in a free state is sin­ter­ing its sul­fide ores: 2As₂S₃ + 9O₂ = 6SO₂ + 2As₂O₃; As₂O₃ + 3C = 2As + 3CO. EKGs were required weekly, and bone marrow aspirates were repeated to assess response. The durability of subsequent remissions with As2O3 and the high incidence of molecular remissions in second or subsequent CR make As2O3 particularly attractive for the treatment of patients with early‐stage disease (i.e., newly diagnosed patients with APL). 5 Answers. With a concentration of 98% of concentrated sulfuric acid and Orpiment made into a certain ratio of the slurry suspension. 1S/As2O3/c3-1-5-2-4 InChI key IKWTVSLWAPBBKU-UHFFFAOYSA-N Show More (10) Description. Other side effects during maintenance included Grade 1 headache (n = 2 patients), fatigue (n = 2 patients), and rash (n = 1 patient). All 12 patients eventually achieved a molecular remission after 3 months of hematologic CR. Therefore, As(III) has to be oxidized to As(V) prior to its removal. Efficacy of Transarterial Embolization with Arsenic Trioxide Oil Emulsion in a Rabbit VX2 Liver Tumor Model. Sigma-Aldrich offers abstracts and full-text articles by [Yasen Maimaitiyiming, Chao Wang, Shi Xu, Khairul Islam, Ye Jia Chen, Chang Yang, Qian Qian Wang, Hua Naranmandura]. Six patients received As2O3 in combination with other agents (Table 3); including mylotarg in 2 patients, idarubicin in 3 patients, and maintenance with a regimen that included ATRA (n = 5 patients) or methotrexate (n = 3 patients). During maintenance, two patients developed peripheral neuropathy (Grade 2 and Grade 3, respectively). Arsenic 2.

Table 3 Effects of confounding factors on the profiles of plasma arsenic metabolites - "Polymorphisms in arsenic (+ 3 oxidation state) methyltransferase (AS3MT) predict the occurrence of hyperleukocytosis and arsenic metabolism in APL patients treated with As2O3" Skip to search form Skip to main content > Semantic Scholar's Logo. Hydrogen peroxide inhibits activity of the IGF-1 receptor kinase. Another secondary endpoint was the achievement of cytogenetic and molecular remission. Proceedings of the National Academy of Sciences. Arsenic Trisulphide. Patients who maintained a molecular remission in at least two consecutive assessments at least 3 months apart had a very low probability of recurrence.17, The mechanism of action of As2O3 is not understood well. The occurrence of hyperleukocytosis with As2O3 treatment seriously affects the early survival rate of APL patients, but no definite explanation for such a complication has been clearly established. Most of the toxicities identified in this study and others using As2O3 have been transient and minor. Three patients have developed recurrent disease: One patient developed recurrent disease after 29 weeks, having received 3 cycles of As2O3 as maintenance therapy; he later achieved a third CR with oral ATRA. Some studies suggest that As2O3 induces APL cell differentiation through direct or indirect activation of RAR‐related signaling pathways.18 This may translate into potential synergy in vitro of As2O3 and ATRA.19 A first attempt with this combination was reported by Shen et al. -retinoic acid, arsenic trioxide, and gemtuzumab In two patients (Patients 3 and 8), the recovery of neutrophils to fulfill the definition of CR required ≥ 28 days after discontinuation of As2O3. Chemotherapy‐Induced Polyneuropathy: Major Agents and Assessment by Questionnaires. Our observation was similar to that of Soignet et al.,10 who found that 16 of 40 patients (40%) who were treated developed QT‐c prolongation, but no fatal arrhythmias were reported. All 12 patients achieved a CR. Role of Arsenic Trioxide in Acute Promyelocytic Leukemia. Thus, of 4 patients who received As2O3 alone for maintenance therapy, 2 patients continued in CR after 71 weeks and 119 weeks of follow‐up, respectively, having received 3 cycles and 1 cycle of As2O3 for maintenance, respectively. Cancer 2003;97:2218–24. Search. (oxidation = increase in oxidation state, reduction = decrease in oxidation state) (oxidation = increase in oxidation state, reduction = decrease in oxidation state) In addition, patients with the AS3MT 14215 (rs3740390) CC genotype had significantly higher plasma iAs% and incidence of hyperleukocytosis, but lower PMI than patients with the CT + TT genotype.
