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). Brief History of Arsenic Discovery History is convoluted Not sure who first discovered Greeks and Romans had slaves mine for arsenic Used in Alchemy Albertus Magnus www.en.wikipedia.com German chemist First to isolate in 1250 AD 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 oxidation in the presence of air or pure oxygen is slow. Three patients (50%) achieved a CR; two patients developed recurrent disease after 3 months and 5 months, and one patient underwent transplantation 1 month into CR.11, An important observation in our study was that all 12 patients achieved a molecular remission, including 7 of 10 patients (70%) in molecular remission that was documented at the time of hematologic CR, 3 patients after additional As2O3 maintenance, and 2 patients in molecular remission that was documented posthematologic CR after chemotherapy was added. 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). As2O3 did not show any cardiotoxicity in the current study. 9 years ago +3. 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. In both of those patients, the abnormality spontaneously corrected without medical intervention. The prevalent predicament of relapsed acute myeloid leukemia. Ten patients were in first recurrence, 1 patient was in second recurrence, and 1 patient was in third recurrence. The occurrence of hyperleukocytosis with As2O3 treatment seriously affects the early survival rate of APL … The median duration of first CR was 52 weeks (range, 13–292 weeks). In this study, all 12 patients (including 1 patient with a second recurrence and 1 patient with a third recurrence) who were treated with As2O3 for a median of 36 days achieved a CR. In natural waters arsenic normally occurs in the oxidation states +III (arsenite) and +V (arsenate). What do you think of the answers? in vitro Another adverse event that has caused concern is the possibility of Torsades‐de‐pointes, which may lead to sudden death,31 including a report from a small series in which three patients died suddenly during the first cycle of treatment and in whom there was no clear evidence of the cause of death, although autopsies were performed in two of those patients.32 Our patients were monitored with weekly EKGs and close clinical follow‐up, and we had no instances of cardiac toxicity, except for mild prolongation of the QT‐c interval in two patients without evidence of cardiac arrhythmias. 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. Other side effects during maintenance included Grade 1 headache (n = 2 patients), fatigue (n = 2 patients), and rash (n = 1 patient). As2S3: (arsenic oxidation state) Let oxidation no of arsenic be x. Its minimum oxidation state we can predict as being -3, and its maximum as +5 Hydrogen peroxide inhibits activity of the IGF-1 receptor kinase. Before ATRA was used widely as frontline therapy, Cortes et al. Picture of reaction: Сoding to search: As2O3 + 6 NaOH = 2 Na3AsO3 + 3 H2O. 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). However, it is unclear whether the biotransformation of arsenic by AS3MT contributes to the promotion of acute … In H3AsO4 (arsenic acid), arsenic has oxidation number +5. 2010 Jul 13;18(1):88-98. doi: 10.1016/j.ccr.2010.06.003.

High-performance liquid chromatography-hydride generation-atomic fluorescence spectrometry (HPLC-HG-AFS) was used to determine the concentrations of plasma arsenic metabolites. Later, this patient achieved a CR with allogenic bone marrow transplantation. These results indicated that AS3MT 14215 (rs3740390) might be used as an indicator for predicting the occurrence of hyperleukocytosis in APL patients treated with As2O3. Treatment was tolerated well overall. 2014 Jul;132:156-67. doi: 10.1016/j.envres.2014.03.012. In its turn arsenic possible oxidation states are -3, +3 and +5. Secondary objectives included determining the rates of molecular remission, remission duration, and survival. Therefore, As(III) has to be oxidized to As(V) prior to its removal. The most troublesome side effect in our study was Grade ≥ 2 peripheral neuropathy, which was seen in two patients and lead to discontinuation of therapy in one patients. Answer Save. The oxidation in the presence of air or pure oxygen is slow. All 12 patients achieved a CR. Non-Coding RNAs as Molecular Targets of Resveratrol Underlying Its Anticancer Effects.
