Synthesis of haptens for the development of a solid-phase immobilized epitope-immunoassay (SPIE-IA) of AZT-TP
摘要:
The synthesis of the reduced form of AZT-triphosphate, 3'-amino-3'-deoxythymidine-5'-triphosphate, and of its stable analog, 3'-amino-3'-deoxythymidine-5'-(alpha;beta:beta,gamma-bis-methylene)triphosphate, is described. AMT-TP and AMT-PCPCP were prepared to develop a specific immunometric assay for AZT-TP. (C) 1999 Elsevier Science Ltd. All rights reserved.
An Unsymmetrical Approach to the Synthesis of Bismethylene Triphosphate Analogues
摘要:
A protected, unsymmetrical bismethylene triphosphate analogue was prepared by sequential Michaelis-Arbuzov reactions on ethyl bis(halomethyl) phosphinates. This species was monodeprotected at one of the terminal phosphonate groups in high yield. The resulting monodeprotected compound was used to achieve the first syntheses of the bismethylene triphosphate analogues of UTP and CTP.

Micaelis-Arbuzov reaction. Special experimental conditions allowed preparation of a set of phosphonate analogs of mono-, di-, and triphosphate. Furthermore, regioselective monodeprotection makes these molecules useful building blocks for the synthesis of analogs of polyphosphorylated compounds of biological interest (e.g. nucleotides), after removal of all phosphonate benzyl ester groups under very

The synthesis of a series of analogues of the different polyphosphorylated metabolites of AZT has been carried out. The compounds were designed in order to raise specific antibodies for the development of highly sensitive titration kits for the intracellular metabolites of AZT. The pyrophosphate moiety in AZT-DP and AZT-TP analogues is mimicked by the methylene bisphosphonate group to provide in vivo stability of the compounds. An omega-amino linker was introduced at the N-3 position on the base to allow the further anchoring of the compounds to a carrier protein before immunization, tentitatively focusing the specificity of the immune response toward the phosphate mimic moiety and the nonnatural sugar.
Synthesis of a non-hydrolyzable AZT-triphosphate analogue designed for the production of anti-AZT-TP antibodies
An enzymatically stable analogue of AZT-triphosphate is prepared in 7 steps starting from thymidine. The thymine moiety is Functionalized at N-3 to allow the Further cross-linking to a carrier protein for subsequent immunization of rabbits in order to raise specific antibodies directed against AZT-TP.
