Acetylphosphate

Acetic acid, monoanhydride with phosphoric acid

C2H5O5P (139.987461)

Acetylphosphate, also known as acetyl-p, belongs to the class of organic compounds known as acyl monophosphates. These are organic compounds containing a monophosphate linked to an acyl group. They have the general structure R-CO-P(O)(O)OH, R=H or organyl. Since acetylphosphate synthesis is known to depend on cholinesterase activity, pseudocholinesterase was assumed to participate to a small extent in acetylphosphate synthesis by cancerous serum. It is also an intermediate in pyruvate metabolism. Acetylphosphate is a drug. Acetylphosphate exists in all living organisms, ranging from bacteria to humans. Acetylphosphate can be converted into acetic acid; which is mediated by the enzyme acylphosphatase-1. It is generated from pyruvate and the formation is catalyzed by pyruvate oxidase (EC:1.2.3.3). In humans, acetylphosphate is involved in the metabolic disorder called the pyruvate dehydrogenase complex deficiency pathway. It is generated from sulfoacetaldehyde, converted to acetyl-CoA and acetate via phosphate acetyltransferase (EC:2.3.1.8) and acetate kinase (EC:2.7.2.1) respectively. Acetylphosphate or actyl phosphate is a compound involved in taurine and hypotaurine metabolism as well as pyruvate metabolism. Cancerous serum produced 37\\% less acetylphosphate than normal serum. Cancerous serum produced 37\\% less acetylphosphate than normal serum. Since acetylphosphate synthesis is known to depend on cholinesterase activity, pseudocholinesterase was assumed to participate to a small extent in acetylphosphate synthesis by cancerous serum.( Rev. sci.

Methylarsonate

Monomethylarsonic acid, ammonium, iron (3+) salt

CH5AsO3 (139.94546400000002)

Methylarsonate is used as a contact herbicide in either the monosodium or disodium salt form. It goes by the trade names Weed-E-Rad, Ansar 170 H.C., Ansar 529 H.C., DiTac and others. Methylarsonate is considered only slightly toxic, having an oral LD50 of 2200 mg/Kg for rats. The inhalation risk is greater with LD50 Rats >20 mg. Long term studies with people exposed to organoarsenicals has shown an increased risk of skin cancer (Spiewak, 2001), lung cancer and some liver cancers, although some recent studies have shown some arsenic containing compounds (specifically Arsine trioxide) may have anticarcinogenic properties (Wang, 2001). In mammals, Methylarsonate is also an intermediate in the detoxification of inorganic arsenic. In the arsenate detoxification I pathway, arsenite reacts with S-adenosyl-L-methionine to produce methylarsonate and S-adenosyl-L-homocysteine. Arsenite methyltransferase catalyzes this reaction. Methylarsonate then reacts with 2 glutathione molecules to produce glutathione disulfide and methylarsonite. This reaction is catalyzed by methylarsonate reductase. Methylarsonate is an organic arsenic compound with adverse effects similar to those of arsenic trioxide. Arsenic is found in the environment primarily as arsenate and arsenite species. Arsenate is reduced to arsenite by arsenate reductase and can be subsequently methylated to Methylarsonate. This is then reduced and methylated to Dimethylarsinate, which can excreted and is considerably less toxic to the organism than any of the previous intermediate compounds. Methylarsonate was formerly included in some vitamin and mineral preparations. It was once used to treat tuberculosis, chorea, and other affections in which the cacodylates were used. Methylarsonate is used as a contact herbicide in either the monosodium or disodium salt form. It goes by the trade names Weed-E-Rad, Ansar 170 H.C., Ansar 529 H.C., DiTac and others.
