  Synthesis of thiazole-4-carboxamide adenine dinucleotide. A powerful inhibitor of IMP dehydrogenase

  摘要：

  The chemical synthesis of thiazole-4-carboxamide adenine dinucleotide (TAD), previously identified as the active anabolite of the oncolytic 2-beta-D-ribofuranosylthiazole-4-carboxamide (TR), has been achieved by three different approaches: (1) incubation of adenosine 5'-monophosphate (AMP) and 2-beta-D-ribofuranosylthiazole-4-carboxamide 5'-monophosphate (TRMP) with excess DCC in aqueous pyridine, (2) reaction of adenosine 5'-phosphoromorpholidate with TRMP in pyridine, and (3) reaction of adenosine-5'-phosphoric di-n-butylphosphinothioic anhydride with TRMP in the presence of AgNO3. While the first approach produced only traces of TAD, the last two afforded 31 and 16% yields, respectively, of isolated TAD. The synthetic material was indistinguishable from biosynthesized TAD as judged by its HPLC behavior, NMR, UV and mass spectra, enzymatic resistance to alkaline phosphatase and susceptibility to venom phosphodiesterase, IMP dehydrogenase inhibitory activity, and cytotoxicity. TAD and TR were equally effective against murine P388 leukemia when employed at equimolar doses.

  A series of dinucleotides, analogous to nicotinamide adenine dinucleotide but containing the five-membered base nucleosides tiazofurin (1a), selenazofurin (1b), ribavirin (2), and AICAR (3) in place of nicotinamide ribonucleoside, were prepared in greater than 50% yield by reacting the corresponding nucleotide imidazolidates (6a-d) with adenosine 5'-monophosphate (AMP). The symmetric dinucleotides of tiazofurin (TTD, 8e) and selenazofurin (SSD, 8f) were also prepared by a similar methodology. These dinucleotides were characterized by 1H NMR and fast atom bombardment MS and were evaluated for their inhibitory potency against a partially purified preparation of tumoral inosine monophosphate dehydrogenase (IMPD) from P388 cells. The order of potency found was SAD (8b) greater than TAD (8a) much greater than SSD (8f) congruent to TTD (8e) congruent to RAD (8c) much much greater than ZAD (8d). On kinetic analysis none of the dinucleotides produced competitive inhibition of IMPD with NAD as a variable substrate. In addition to their superior IMPD inhibitory activity, SAD and TAD appear to be the only dinucleotides, besides NAD, that are formed naturally by the NAD pyrophosphorylase from P388 lymphoblasts.
