  Bisubstrate Inhibitors of Biotin Protein Ligase in Mycobacterium tuberculosis Resistant to Cyclonucleoside Formation

  摘要：

  Mycobacterium tuberculosis (Mtb), the etiological agent of tuberculosis, is the leading cause of bacterial infectious disease mortality. Biotin protein ligase (BirA) globally regulates lipid metabolism in Mtb through the posttranslational biotinylation of acyl coenzyme A carboxylases (ACCs) involved in lipid biosynthesis and is essential for Mtb survival. We previously developed a rationally designed bisubstrate inhibitor of BirA that displays potent enzyme inhibition and whole cell activity against multidrug resistant and extensively drug resistant Mtb strains. Here we present the design, synthesis, and evaluation of a focused series of inhibitors, which are resistant to cyclonucleoside formation, a key decomposition pathway of our initial analogue. Improved chemical stability is realized through replacement of the adenosyl N-3 nitrogen and C-5' oxygen atom with carbon as well as incorporation of a bulky group on the nucleobase to prevent the required synconformation necessary for proper alignment of N-3 with C-5'.

  DOI：10.1039/b9nj00595a

  日期：——

  To study the properties of hydrolysates of cyclic adenosine diphosphate ribose (cADPR), a series of novel acyclic analogues of cADPR with an ether chain as the northern moiety and 8-substituted adenine or hypoxanthine as the base moiety were synthesized via an N1 substitution construction, followed by bisphosphorylation, phosphoramidition or pyrophosphorylation. These compounds also provide various precursors for synthesizing cADPR analogues.

  An efficient synthesis of cyclic ADP-carbocyclic-ribose (2), as a stable mimic for cyclic ADP-ribose, was achieved. Treatment of N 1-carbocyclic-ribosyla-denosine bisphosphate derivative 10 with AgNO3 in the presence of molecular sieves 3A in pyridine gave the desired cyclic product in 93% yield, which was deprotected to give the target cyclic ADP-carbocyclic-ribose (2).

  The synthesis of cyclic ADP-carbocyclic-ribose (cADPcR, 4) designed as a stable mimic of cyclic ADP-ribose (cADPR, 1), a Ca2+-mobilizing second messenger, was achieved using as the key step a condensation reaction with the phenylthiophosphate-type substrate 14 to form an intramolecular pyrophosphate linkage. The N-1-carbocyclic-ribosyladenosine derivative 16 was prepared via the condensation between
