Arsenic trioxide powder.. Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table.The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds.
Later, on similar routes, the corresponding and isostructural arsenic and antimony species were also synthesized. [3] Other synthetic methods involve deprotonation of OH or NH groups in the presence of ECl 3 (E=P, [ 4 ] As, Sb [ 5 ] and Bi [ 6 ] ), salt metathesis [ 7 ] or reduction of pentavalent pnictogen compounds.
Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the ...

The soils hold 1 to 10 parts per million of arsenic, and seawater carries 1.6 parts per billion of arsenic. Arsenic comprises 100 parts per billion of a typical human by weight. Some arsenic exists in elemental form, but most arsenic is found in the arsenic minerals orpiment , realgar , arsenopyrite , and enargite .
Arsenic trioxide, even at low concentrations, causes the degradation of PML/RARα, thereby partially restoring the differentiation of cancerous promyelocytes. [31] Arsenic trioxide activates JNK (c-Jun N-terminal kinase), also known as stress-activated protein kinase, which belongs to the MAPK (mitogen-activated protein kinase) family. These ...
Arsenic trioxide is indicated in combination with tretinoin for treatment of adults with newly-diagnosed low-risk acute promyelocytic leukemia whose acute promyelocytic leukemia is characterized by the presence of the t(15;17) translocation or PML/RAR-alpha gene expression; and for induction of remission and consolidation in patients with acute promyelocytic leukemia who are refractory to, or ...
