Abstract
Mycobacterium tuberculosis (Mtb) is an intracellular bacterium that causes a highly contagious and potentially lethal tuberculosis (TB) in humans. It can maintain a dormant TB infection within the host. DosR (dormancy survival regulator) (Rv3133c) has been recognized as one of the key transcriptional proteins regulating bacterial dormancy and participating in various metabolic processes. In this study, we extensively investigate the still not well-comprehended role and mechanism of DosR in Mycobacterium bovis (M. bovis) Bacillus Calmette-Guérin (BCG) through a combined omics analysis. Our study finds that deleting DosR significantly affects the transcriptional levels of 104 genes and 179 proteins. Targeted metabolomics data for amino acids indicate that DosR knockout significantly upregulates L-Aspartic acid and serine synthesis, while downregulating seven other amino acids, including L-histidine and lysine. This suggests that DosR regulates amino acid synthesis and metabolism. Taken together, these findings provide molecular and metabolic bases for DosR effects, suggesting that DosR may be a novel regulatory target.

Abstract
Chiral sulfones extensively exist in drugs, agricultural chemicals, chiral organic intermediates, and functional materials. Their importance causes the rapid development of their synthetic methods in recent years. Many transition metal complex catalysts with chiral ligands and chiral organocatalysts are adopted in synthesis of chiral sulfones. Most of the methods to construct chiral sulfones are based on the reduction of unsaturated sulfones and the introduction of sulfone groups into unsaturated hydrocarbons. This review describes all classes of asymmetric reactions for synthesis of chiral sulfones.

Abstract
Protein phosphorylation/dephosphorylation is an important regulatory mechanism that controls many key physiological processes. Numerous pathogens successfully use kinases and phosphatases to internalize, replicate, and survive, modifying the host′s phosphorylation profile or signal transduction pathways. Multiple phosphatases and kinases from diverse bacterial pathogens have been implicated in human infections before. In this work, we have identified and characterized the dual specificity protein/lipid phosphatase LmDUSP1 as a novel virulence factor governing Leishmania mexicana infection. The LmDUSP1-encoding gene (LmxM.22.0250 in L. mexicana) has been acquired from bacteria via horizontal gene transfer. Importantly, its orthologues have been associated with virulence in several bacterial species, such as Mycobacterium tuberculosis and Listeria monocytogenes. Leishmania mexicana with ablated LmxM.22.0250 demonstrated severely attenuated virulence in the experimental infection of primary mouse macrophages, suggesting that this gene facilitates Leishmania pathogenicity in vertebrates. Despite significant upregulation of LmxM.22.0250 expression in metacyclic promastigotes, its ablation did not affect the ability of mutant cells to differentiate into virulent stages in insects. It remains to be further investigated which specific biochemical pathways involve LmDUSP1 and how this facilitates the parasite′s survival in the host. One of the interesting possibilities is that LmDUSP1 may target host′s substrate(s), thereby affecting its signal transduction pathways.

Abstract
![]()
The
development of efficient methods for the generation of enantioenriched
sulfonamides and sulfones is an important objective for fields such
as organic synthesis and medicinal chemistry; however, there have
been relatively few reports of direct catalytic asymmetric approaches
to controlling the stereochemistry of the sulfur-bearing carbon of
such targets. In this report, we describe nickel-catalyzed stereoconvergent
Negishi arylations and alkenylations of racemic α-bromosulfonamides
and -sulfones that furnish the desired cross-coupling product in very
good ee and yield for an array of reaction partners. Mechanistic studies
are consistent with the generation of a radical intermediate that
has a sufficient lifetime to diffuse out of the solvent cage and to
cyclize onto a pendant olefin.

Abstract
The global pandemic of drug sensitive tuberculosis (TB) as well as the increasing threat from various multidrug resistant forms of TB drives the quest for newer, safer, more effective TB treatment options. The general lack of success in progressing novel chemical matter from high throughput screens of Mycobacterium tuberculosis (M.tb) biochemical targets has prompted resurgence in interest and efforts in prosecuting mycobacterial phenotypic screens. Whole cell active compounds identified from such screens offer significant intrinsic advantages over biochemical screening hits, and derivatives of many of these have proven invaluable in helping to fill the current TB drug development pipeline. Modern techniques for "de-orphaning" such screening hits (i.e., determining their specific biological mechanism of action) offer the possibility of ultimately identifying improved next-generation chemical series by screening these essential, pharmacologically validated biochemical targets as well.

Abstract
For centuries the treatment of TB has presented an enormous challenge to global health. In the 20th century, the treatment of TB patients with long-term multidrug therapy gave hope that TB could be controlled and cured; however, contrary to these expectations and coinciding with the emergence of AIDS, the world has witnessed a rampant increase in hard-to-treat cases of TB, along with the emergence of highly virulent and multidrug-resistant Mycobacterium tuberculosis strains. Unfortunately, these bacteria are now circulating around the world, and there are few effective drugs to treat them. As a result, the prospects for improved treatment and control of TB in the 21st century have worsened and we urgently need to identify new therapies that deal with this problem. The potential use of immunotherapy for TB is now of greater consideration than ever before, as immunotherapy could potentially overcome the problem of drug resistance. TB immunotherapy targets the already existing host anti-TB immune response and aims to enhance killing of the bacilli. For this purpose, several approaches have been used: the use of anti-Mycobacteria antibodies; enhancing the Th1 protective responses by using mycobacterial antigens or increasing Th1 cytokines; interfering with the inflammatory process and targeting of immunosuppressive pathways and targeting the cell activation/proliferation pathways. This article reviews our current understanding of TB immunity and targets for immunotherapy that could be used in combination with current TB chemotherapy.

Abstract
There is an increasing flow of new antituberculosis chemical entities entering the tuberculosis drug development pipeline. Although this is encouraging, the current number of compounds is too low to meet the demanding criteria required for registration, shorten treatment duration, treat drug-resistant infection, and address pediatric tuberculosis cases. More new chemical entities are needed urgently to supplement the pipeline and ensure that more drugs and regimens enter clinical practice. Most drug discovery projects under way exploit enzyme systems deemed essential in a specific Mycobacterium tuberculosis biosynthetic pathway or develop chemical scaffolds identified by phenotypic screening of compound libraries, specific pharmacophores or chemical clusters, and natural products. Because the development of a compound for treating tuberculosis is even longer than for treating other infection indications, the identification of selective, potent, and safe chemical entities early in the drug development process is essential to ensure that the pipeline is filled with new candidates that have the best chance to reach the clinic.
