Triazole-linked inhibitors of inosine monophosphate dehydrogenase from human and Mycobacterium tuberculosis.
Chen L., Wilson D.J., Xu Y., Aldrich C.C., Felczak K., Sham Y.Y., Pankiewicz K.W.
The modular nature of nicotinamide adenine dinucleotide (NAD)-mimicking inosine monophsophate dehydrogenase (IMPDH) inhibitors has prompted us to investigate novel mycophenolic adenine dinucleotides (MAD) in which 1,2,3-triazole linkers were incorporated as isosteric replacements of the pyrophosph ... >> More
The modular nature of nicotinamide adenine dinucleotide (NAD)-mimicking inosine monophsophate dehydrogenase (IMPDH) inhibitors has prompted us to investigate novel mycophenolic adenine dinucleotides (MAD) in which 1,2,3-triazole linkers were incorporated as isosteric replacements of the pyrophosphate linker. Synthesis and evaluation of these inhibitors led to identification of low nanomolar inhibitors of human IMPDH and more importantly the first potent inhibitor of IMPDH from Mycobacterium tuberculosis (mtIMPDH). Computational studies of these IMPDH enzymes helped rationalize the observed structure-activity relationships. Additionally, the first cloning, expression, purification and characterization of mtIMPDH is reported. << Less

Identification of novel diphenyl urea inhibitors of Mt-GuaB2 active against Mycobacterium tuberculosis.

In contrast with most bacteria, which harbour a single inosine monophosphate dehydrogenase (IMPDH) gene, the genomic sequence of Mycobacterium tuberculosis H37Rv predicts three genes encoding IMPDH: guaB1, guaB2 and guaB3. These three genes were cloned and expressed in Escherichia coli to evaluate functional IMPDH activity. Purified recombinant Mt-GuaB2, which uses inosine monophosphate as a substrate, was identified as the only active GuaB orthologue in M. tuberculosis and showed optimal activity at pH 8.5 and 37 °C. Mt-GuaB2 was inhibited significantly in vitro by a panel of diphenyl urea-based derivatives, which were also potent anti-mycobacterial agents against M. tuberculosis and Mycobacterium smegmatis, with MICs in the range of 0.2-0.5 μg ml(-1). When Mt-GuaB2 was overexpressed on a plasmid in trans in M. smegmatis, a diphenyl urea analogue showed a 16-fold increase in MIC. Interestingly, when Mt-GuaB orthologues (Mt-GuaB1 and 3) were also overexpressed on a plasmid in trans in M. smegmatis, they also conferred resistance, suggesting that although these Mt-GuaB orthologues were inactive in vitro, they presumably titrate the effect of the inhibitory properties of the active compounds in vivo. << Less
