Abstract
Natural arsenolipids are analogues of neutral lipids, like monoglycerides, glycolipids, phospho- and also phosphonolipids. They have been found in microorganisms, fungi, plants, lichens, in marine mollusks, sponges, other invertebrates, and in fish tissues. This review presented structures of natural arsenolipids (and derivatives), their distribution, biogenesis in algae and invertebrates, synthesis, and also biological activity. Arsenolipids are thought to be end products of arsenate detoxification processes, involving reduction and oxidative methylation and adenosylation. The proposed biogenesis of arsenolipids is based on the natural occurrence of arsenic metabolites, and all the intermediates in the proposed pathway have been identified as natural products of algal origin. Different arseno species are shown to be inhibitors of glycerol kinase, bovine carbonic anhydrase, and also is an effective therapy for acute promyelocytic leukemia, and there has been promising activity noted in other hematologic and solid tumors. Arsonoliposomes demonstrated high anti-trypanosomal activity against Trypanosoma brucei and inhibit growth of some types of cancer cells (HL-60,C6 and GH3).

Abstract
In the present study, arsanical-based affinity chromatography for pyruvate kinase (PK) isolation was explored. p-Arsanilic acid (4-aminophenyl arsonic acid), which contains an arsonic acid moiety structurally similar to inorganic pentavalent arsenate, was conjugated to Sepharose 4B via its para-amino group to form an As(V)-Sepharose matrix. The cellular proteins from KB cells bound to arsonic acid moieties were eluted by 50 mM sodium arsenate in Tris-HCl buffer (50 mM, pH 7.6). A single protein band with a molecular mass of 58 kDa was shown on a sodium dodecyl sulfate-polyacrylamide gel. By immunoblotting, amino acid sequencing and enzymatic analysis, the sodium arsenate-eluted 58-kDa protein was demonstrated to be a human PK (type M2). By using this one-step As(V)-Sepharose chromatography, PK from KB cells was purified 35.4-fold with a specific activity of 153.15 U/mg protein in the presence of 6 mM fructose-1,6-biphosphate. Although PK was eluted from an As(V)-Sepharose column with sodium arsenate, PK activity was apparently inhibited by the used eluent system, but not by p-arsanilic acid, indicating a specific interaction of As(V) to PK. In summary, our results indicate that As(V)-Sepharose can serve as a simple and efficient chromatographic support for PK purification from KB cells.

Abstract
The isosteric arsenical analogue of glycerol 3-phosphate, 3,4-dihydroxybutylarsonic acid, is a good substrate for rabbit muscle glycerol-3-phosphate dehydrogenase. Its oxidation is accompanied by release of arsenite. This release seems to be due to a spontaneous elimination of arsenite by 3-oxoalkylarsonic acids, as it is also observed in (1) the oxidation of 3-hydroxypropylarsonic acid by yeast alcohol dehydrogenase, (2) treatment of 3,4-dihydroxybutylarsonic acid with periodate and (3) nonenzymic transamination of the glutamate analogue 2-amino-4-arsonobutyric acid. Enzymic formation of 3-oxoalkylarsonic acids in cells can therefore be lethal, as arsenite is poisonous to most organisms because of its high affinity for dithiols such as dihydrolipoyl groups.

Abstract
3-Arsonopyruvate was prepared in four steps from glycine. The arsenic-carbon bond was formed by a Meyer reaction between alkaline arsenite and 2-bromo-3-hydroxy-2-(hydroxymethyl)propionic acid; the 3-arsono-2-hydroxy-2-(hydroxymethyl) propionic acid formed was oxidized with periodate to give 3-arsonopyruvate. This proves to be an alternative substrate for phosphoenolpyruvate mutase, giving pyruvate, which was assayed using lactate dehydrogenase. The K(m) is 20 microM, similar to that observed for the natural substrate phosphonopyruvate (17 microM), whereas the kcat. of 0.01 s-1 was much lower than that for phosphonopyruvate (58 s-1). Arsonopyruvate competitively inhibited the action of the mutase on phosphonopyruvate.

Abstract
(RS)-3-Arsono-2-(hydroxymethyl)propionic acid was synthesized by the action of alkaline arsenite on 3-bromo-2-(bromomethyl)propionic acid. It is a substrate for yeast enolase (EC 4.2.1.11) with a Km of 6.5 mM (for 2-phospho-D-glycerate Km = 0.08 mM). The catalytic constant of the enzyme with the arsonomethyl analogue is 230 times lower than with 2-phosphoglycerate.

Abstract
2-Aminoethylarsonic acid was tested for its ability to act as a substrate for ethanolamine-phosphate cytidylytransferase as a cytidylyl acceptor in place of ethanolamine phosphate. The expected product, like all mixed anhydrides of arsonic acids, should hydrolyse spontaneously with regeneration of the substrate analogue and CMP formation; such CMP production was observed. The limiting velocity with aminoethylarsonic acid is about 90% that with ethanolamine phosphate, and the Michaelis constant is below 20 mM.

Abstract
DNA-directed RNA polymerase from Escherichia coli can break down RNA by catalysing the reverse of the reaction: NTP + (RNA)n = (RNA)n+1 + PPi where n indicates the number of nucleotide residues in the RNA molecule, to yield nucleoside triphosphates. This reaction requires the ternary complex of the polymerase with template DNA and the RNA that it has synthesized. It is now shown that methylenebis(arsonic acid) [CH2(AsO3H2)2], arsonomethylphosphonic acid (H2O3As-CH2-PO3H2) and arsonoacetic acid (H2O3As-CH2-CO2H) can replace pyrophosphate in this reaction. When they do so, the low-Mr products of the reaction prove to be nucleoside 5'-phosphates, so that the arsenical compounds endow the polymerase with an artificial exonuclease activity, an effect previously found by Rozovskaya, Chenchik, Tarusova, Bibilashvili & Khomutov [(1981) Mol. Biol. (Moscow) 15, 636-652] for phosphonoacetic acid (H2O3P-CH2-CO2H). This is explained by instability of the analogues of nucleoside triphosphates believed to be the initial products. Specificity of recognition of pyrophosphate is discussed in terms of the sites, beta and gamma, for the -PO3H2 groups of pyrophosphate that will yield P-beta and P-gamma of the nascent nucleoside triphosphate. Site gamma can accept -AsO3H2 in place of -PO3H2, but less well; site beta can accept both, and also -CO2H. We suggest that partial transfer of an Mg2+ ion from the attacking pyrophosphate to the phosphate of the internucleotide bond of the RNA may increase the nucleophilic reactivity of the pyrophosphate and the electrophilicity of the diester, so that the reaction is assisted.
