Abstract
To understand the antibacterial mechanism of the new bactericide 2-(methylsulfonyl)-5- (4-fluorobenzyl)-1, 3, 4-oxadiazole (Generic name: Fubianezuofeng), we performed label-free quantitative proteomics analysis of the response of Xanthomonas axonopodis pv. citri (Xac) strain 29-1 to Fubianezuofeng. A total of 1133 proteins were identified in the treatment and control groups. Upon treatment with the 1/2 minimum inhibitory concentration (MIC), 339 proteins were found to be differentially expressed (fold changes>1.5, p<0.05) with 99 upregulated and 240 down-regulated. In comparison, 314 proteins were differentially expressed (125 up-regulated, 189 down-regulated) at MIC. The differentially expressed proteins were enriched for those involved in the pyrimidine metabolic pathway. The results offer a complete view of the proteome changes in bacteria in response to Fubianezuofeng.

Abstract
A short synthetic route to β,d-arabinofuranosyl 1-C-sulfonic acid (7), a possible biomimetic for the arabinofuranosyl anomeric phosphate, is described. The furanosyl 1-C-sulfonate was prepared by buffered DMDO oxidation of an S-acetyl-1-thio-β-arabinofuranose derivative. Deprotection under mild conditions allowed isolation of the free sulfonic acid without desulfonylation.

Abstract
Decaprenyl-phospho-arabinose (beta-D-arabinofuranosyl-1-O-monophosphodecaprenol), the only known donor of d-arabinose in bacteria, and its precursor, decaprenyl-phospho-ribose (beta-D-ribofuranosyl-1-O-monophosphodecaprenol), were first described in 1992. En route to D-arabinofuranose, the decaprenyl-phospho-ribose 2'-epimerase converts decaprenyl-phospho-ribose to decaprenyl-phospho-arabinose, which is a substrate for arabinosyltransferases in the synthesis of the cell-wall arabinogalactan and lipoarabinomannan polysaccharides of mycobacteria. The first step of the proposed decaprenyl-phospho-arabinose biosynthesis pathway in Mycobacterium tuberculosis and related actinobacteria is the formation of D-ribose 5-phosphate from sedoheptulose 7-phosphate, catalysed by the Rv1449 transketolase, and/or the isomerization of d-ribulose 5-phosphate, catalysed by the Rv2465 d-ribose 5-phosphate isomerase. d-Ribose 5-phosphate is a substrate for the Rv1017 phosphoribosyl pyrophosphate synthetase which forms 5-phosphoribosyl 1-pyrophosphate (PRPP). The activated 5-phosphoribofuranosyl residue of PRPP is transferred by the Rv3806 5-phosphoribosyltransferase to decaprenyl phosphate, thus forming 5'-phosphoribosyl-monophospho-decaprenol. The dephosphorylation of 5'-phosphoribosyl-monophospho-decaprenol to decaprenyl-phospho-ribose by the putative Rv3807 phospholipid phosphatase is the committed step of the pathway. A subsequent 2'-epimerization of decaprenyl-phospho-ribose by the heteromeric Rv3790/Rv3791 2'-epimerase leads to the formation of the decaprenyl-phospho-arabinose precursor for the synthesis of the cell-wall arabinans in Actinomycetales. The mycobacterial 2'-epimerase Rv3790 subunit is similar to the fungal D-arabinono-1,4-lactone oxidase, the last enzyme in the biosynthesis of D-erythroascorbic acid, thus pointing to an evolutionary link between the D-arabinofuranose- and L-ascorbic acid-related pathways. Decaprenyl-phospho-arabinose has been a lead compound for the chemical synthesis of substrates for mycobacterial arabinosyltransferases and of new inhibitors and potential antituberculosis drugs. The peculiar (omega,mono-E,octa-Z) configuration of decaprenol has yielded insights into lipid biosynthesis, and has led to the identification of the novel Z-polyprenyl diphosphate synthases of mycobacteria. Mass spectrometric methods were developed for the analysis of anomeric linkages and of dolichol phosphate-related lipids. In the field of immunology, the renaissance in mycobacterial polyisoprenoid research has led to the identification of mimetic mannosyl-beta-1-phosphomycoketides of pathogenic mycobacteria as potent lipid antigens presented by CD1c proteins to human T cells.

Abstract
A route for the synthesis of bicyclo[3.1.0]hexane-derived conformationally restricted analogues of beta-arabinofuranosyl and alpha-galactofuranosyl rings is described. Advantage is taken of the pseudo-enantiomeric relationship between the two ring systems to develop a route that provides both targets from a single precursor. Key steps include a base-promoted ring contraction of an epoxy ketone obtained from cyclohexane-1,4-dione to give the bicyclo[3.1.0]hexane ring system and a late stage resolution involving esterification with O-acetyl-(S)-mandelic acid.

Abstract
The major structural component of the cell wall of Mycobacterium tuberculosis is a lipidated polysaccharide, the mycoyl-arabinogalactan-peptidoglycan (mAGP) complex. This glycoconjugate plays a key role in the survival of the organism, and thus, enzymes involved in its biosynthesis have attracted attention as sites for drug action. At the core of the mAGP is a galactan composed of D-galactofuranose residues attached via alternating beta-(1-->5) and beta-(1-->6) linkages. A single enzyme, glfT, has been shown to synthesize both glycosidic linkages. We report here the first high-level expression and purification of glfT by expression of the Rv3808c gene in Escherichia coli C41(DE3). Following a three-step purification procedure, 3-7 mg of protein of >95% purity was isolated from each liter of culture. We subsequently probed the substrate specificity of glfT by evaluating a panel of potential mono- and oligosaccharide substrates and demonstrated, for the first time, that trisaccharides are better substrates than disaccharides and that one disaccharide, in which the terminal D-galactofuranose residue is replaced with an L-arabinofuranose moiety, is a weak substrate. Kinetic characterization of the enzyme using four of the oligosaccharide acceptors gave K(m) values ranging from 204 microM to 1.7 mM. Through the use of NMR spectroscopy and mass spectrometry, we demonstrated that this recombinant enzyme, like the wild-type protein, is bifunctional and can synthesize both beta-(1-->6) and beta-(1-->5)-linkages in an alternating fashion. Access to purified glfT is expected to facilitate the development of high-throughput assays for the identification of inhibitors of the enzyme, which are potential antituberculosis agents.

Abstract
A series of C-3 alkyl and arylalkyl 2,3-dideoxy hex-2-enopyranoside derivatives were synthesized by Morita-Baylis-Hillman reaction using enulosides 4, 5, and 6 and various aliphatic and aromatic aldehydes. The compounds were evaluated in vitro for the complete inhibition of growth of Mycobacterium tuberculosis H37Rv. They exhibited moderate to good activity in the range of 25-1.56 mug/mL. Among these, 4d, 4h, 5c, and 4hr showed activity at minimum inhibitory concentrations, 3.12, 6.25, 1.56, and 1.56 mug/mL, respectively. These compounds were safe against cytotoxicity in VERO cell line and mouse macrophage cell line J 744A.1. A QSAR analysis by CP-MLR with alignment-free 3D-descriptors indicated the relevance of structure space comparable to the minimum energy conformation (from conformational analysis) of 5c to the activity. The study indicates that the compounds attaining the conformational space of 5c and reflecting some symmetry, minimum eccentricity, and closely placed geometric and electronegativity centers therein are favorable for activity.

A bis-arylsulfonamide, 7, has been identified that exhibits growth inhibition of Mycobacterium smegmatis at less than 25 microg/mL, but has no such activity against Escherichia coli or Staphylococcus aureus. A closely related bis-arylsulfonamide (8) was much less active, but was the only other compound among 54 arylsulfonamides tested with detectable growth inhibition of M. smegmatis.

Abstract
Tuberculosis is today amongst the worldwide health threats. As resistant strains of Mycobacterium tuberculosis have slowly emerged, treatment failure is too often a fact, especially in countries lacking the necessary health care organisation to provide the long and costly treatment adapted to patients. Because of lack of treatment or lack of adapted treatment, at least two million people will die of tuberculosis this year. Due to this concern, this infectious disease was the focus of renewed scientific interest in the last decade. Regimens were optimized and much was learnt on the mechanisms of action of the antituberculosis drugs used. Moreover, the quest for original drugs overcoming some of the problems of current regimens also became the focus of research programmes and many new series of M. tuberculosis growth inhibitors were reported. This review presents the drugs currently used in antituberculosis treatments and the most advanced compounds undergoing clinical trials. We then provide a description of their mechanism of action along with other series of inhibitors known to act on related biochemical targets. This is followed by other inhibitors of M. tuberculosis growth, including recently reported compounds devoid of a reported mechanism of action.

Abstract
Described is the synthesis of polyprenyl 2-deoxy-2-fluoro-beta-D-arabinofuranosyl phosphate derivatives, including an analog of decaprenyl beta-D-arabinofuranosyl phosphate, the donor species used by the arabinosyltransferases involved in mycobacterial cell-wall biosynthesis. The targets were synthesized via a route involving the synthesis of a protected beta-D-arabinofuranosyl phosphate derivative, its coupling with a polyprenyl trichloroacetimidate, and then deprotection of the resulting product. The use of arabinofuranosyl phosphates with the monosaccharide hydroxyl groups protected as either silyl ethers or benzoate esters was explored. Although the coupling yields between the phosphate and polyprenyl trichloroacetimidates were comparable with either type of protecting group, access to the benzoyl-protected derivative was more efficient and therefore gave the products in higher overall yield.
