Synthesis and biological evaluation of phosphonic and thiophosphoric acid derivatives of lysophosphatidic acid.
Using an N-oleoyl ethanolamide scaffold, a series of phosphate polar head group analogues of LPA comprised of various alpha-substituted phosphonates and thiophosphates was prepared. In a broken cell GTP[gamma35S] binding assay, agonist activity was evaluated at the three LPA receptors of the endothelial differentiation gene (Edg) family. This study has resulted in the discovery of a nonhydrolyz...
متن کاملPhosphonic acid: preparation and applications
The phosphonic acid functional group, which is characterized by a phosphorus atom bonded to three oxygen atoms (two hydroxy groups and one P=O double bond) and one carbon atom, is employed for many applications due to its structural analogy with the phosphate moiety or to its coordination or supramolecular properties. Phosphonic acids were used for their bioactive properties (drug, pro-drug), f...
متن کاملA Density Functional Theory Study of Structure of Phosphonic Acid
The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...
متن کاملSynthesis of Novel 2′(β)-Methyl-5′-deoxyapiose Nucleoside Phosphonic Acid Analogues as Antiviral Agents
Novel 2'(β)-methyl-5'-deoxyapiose purine phosphonic acid analogues were designed and synthesized from 2-propanone1,3-diacetate. Condensation successfully proceeded from a glycosyl donor 9 under Vorbrüggen conditions. Condensation of aldehyde 14 with Wittig reagent [(diethoxyphosphinyl)methylidene] triphenylphosphorane gave the desired nucleoside phosphonate analogues 15. Ammonolysis and hydroly...
متن کاملATTEMPTED SYNTHESIS OF 5' - DEOXY - 5' - PHOSPHONO - ISOCYTIDINE SYNTHESIS OF PHOSPHONIC ACID DERIVATIVES OF ACYCLO - NUCLEOSIDES. PREPARATION OF 1- ?- D- ARABINOFURANOSYL PYRIMIDINES
The synthesis of 5' - deoxynucleoside 5' - phosphonates which contains a 5' - CP bond in place of the 5' -COP bond of the naturally occuring nucleotides is described. The preparation of phosphonate derivatives of acyclo - nucleosides and a simple method for the conversion of 1-? -D-ribofuranosyl pyrimidines to the corresponding 1-? -D-arabinofuranosyl pyrimidines are also explained
