Enzymatic synthesis of 2′-ara and 2′-deoxy analogues of c-di-GMP
摘要:
The substrate specificity of recombinant full-length diguanylate cyclase (DGC) of Thermotoga maritima with mutant allosteric site was investigated. It has been originally shown that the enzyme could use GTP closest analogues - 2 '-deoxyguanosine-5 '-triphosphate (dGTP) and 9-beta-D-arabinofuranosyl-guanine-5 '-triphosphate (araGTP) as the substrates. The first demonstrations of an enzymatic synthesis of bis-(3 '-5 ')-cyclic dimeric deoxyguanosine monophosphate (c-di-dGMP) and the previously unknown bis-(3 '-5 ')-cyclic dimeric araguanosine monophosphate (c-di-araGMP) using DGC of T. maritima in the form of inclusion bodies have been provided.

The present invention provides methods of treating cancer using inhibitors of protein kinases. The inhibitors of protein kinases are combined with agents that inhibit a cellular ATP synthetic pathway. Inhibitors of ATP synthesis include inhibitors of de novo purine biosynthesis, inhibitors of the salvage pathway of ATP biosynthesis, and inhibitors of the enzyme inosine monophosphate dehydrogenase.

The present invention provides methods of treating cancer using inhibitors of inosine monophosphate dehydrogenase (IMPDH). The IMPDH inhibitors are combined with compounds that inhibit cellular processes regulated by GTP or ATP. Also provided are prodrugs of the IMPDH inhibitor mizoribine and its aglycone. The prodrugs are useful in practicing the methods of the invention, including immunosuppressive therapy and treatment of cancer by prolonged administration without additional therapeutic compounds.
