Abstract
In this study, we present a novel series of (E)-4-((2-(pyrazine-2-carbonyl) hydrazineylidene)methyl)phenyl benzenesulfonate (T1-T8) and 4-((E)-(((Z)-amino(pyrazin-2-yl)methylene)hydrazineylidene)methyl)phenyl benzenesulfonate (T9-T16) derivatives which exert their inhibitory effects on decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1) through the formation of hydrogen bonds with the pivotal active site Cys387 residue. Their effectiveness against the M. tuberculosis H37Rv strain was examined and notably, three compounds (namely T4, T7, and T12) exhibited promising antitubercular activity, with a minimum inhibitory concentration (MIC) of 1.56 µg/mL. The target compounds were screened for their antibacterial activity against a range of bacterial strains, encompassing S. aureus, B. subtilis, S. mutans, E. coli, S. typhi, and K. pneumoniae. Additionally, their antifungal efficacy against A. fumigatus and A. niger also was scrutinized. Compounds T6 and T12 demonstrated significant antibacterial activity, while compound T6 exhibited substantial antifungal activity. Importantly, all of these active compounds demonstrated exceedingly low toxicity without any adverse effects on normal cells. To deepen our understanding of these compounds, we have undertaken an in silico analysis encompassing Absorption, Distribution, Metabolism, and Excretion (ADME) considerations. Furthermore, molecular docking analyses against the DprE1 enzyme was conducted and Density-Functional Theory (DFT) studies were employed to elucidate the electronic properties of the compounds, thereby enhancing our understanding of their pharmacological potential.

Abstract
Decaprenylphosphoryl-β-d-ribose 2'-epimerase (DprE1) is a critical flavoenzyme in Mycobacterium tuberculosis, catalyzing a vital step in the production of lipoarabinomannan and arabinogalactan, both of which are essential for cell wall biosynthesis. Due to its periplasmic localization, DprE1 is a susceptible target, and several compounds with diverse scaffolds have been discovered that inhibit this enzyme, covalently or noncovalently. We evaluated a total of ∼1519 DprE1 inhibitors disclosed in the literature from 2009 to April 2022 by performing an in-depth analysis of physicochemical descriptors and absorption, distribution, metabolism, excretion, and toxicity (ADMET), to gain new insights into these properties in DprE1 inhibitors. Several molecular properties that should facilitate the design and optimization of future DprE1 inhibitors are described, allowing for the development of improved analogues targeting M. tuberculosis.

Abstract
The emergence of drug-resistant mycobacteria, including Mycobacterium tuberculosis (Mtb) and non-tuberculous mycobacteria (NTM), poses an increasing global threat that urgently demands the development of new potent anti-mycobacterial drugs. One of the approaches toward the identification of new drugs is fragment-based drug discovery (FBDD), which is the most ingenious among other drug discovery models, such as structure-based drug design (SBDD) and high-throughput screening. Specialized techniques, such as X-ray crystallography, nuclear magnetic resonance spectroscopy, and many others, are part of the drug discovery approach to combat the Mtb and NTM global menaces. Moreover, the primary drawbacks of traditional methods, such as the limited measurement of biomolecular toxicity and uncertain bioavailability evaluation, are successfully overcome by the FBDD approach. The current review focuses on the recognition of fragment-based drug discovery as a popular approach using virtual, computational, and biophysical methods to identify potent fragment molecules. FBDD focuses on designing optimal inhibitors against potential therapeutic targets of NTM and Mtb (PurC, ArgB, MmpL3, and TrmD). Additionally, we have elaborated on the challenges associated with the FBDD approach in the identification and development of novel compounds. Insights into the applications and overcoming the challenges of FBDD approaches will aid in the identification of potential therapeutic compounds to treat drug-sensitive and drug-resistant NTMs and Mtb infections.

THP-1 and Dictyostelium Infection Models for Screening and Characterization of Anti-Mycobacterium abscessus Hit Compounds. Antimicrob Agents Chemother 2019; 64:AAC.01601-19.

Abstract
!!NCR1!! presents a great challenge to antimycobacterial therapy due to its innate resistance against most antibiotics. M. abscessus is able to grow intracellularly in human macrophages, suggesting that intracellular models can facilitate drug discovery. Thus, we have developed two host cell models: human macrophages for use in a new high-content screening method for M. abscessus growth and a Dictyostelium discoideum infection model with the potential to simplify downstream genetic analysis of host cell factors. A screen of 568 antibiotics for activity against intracellular M. abscessus led to the identification of two hit compounds with distinct growth inhibition. A collection of 317 human kinase inhibitors was analyzed, with the results yielding three compounds with an inhibitory effect on mycobacterial growth, strengthening the notion that host-directed therapy can be applied for M. abscessus.

Abstract
Mycobacterium abscessus is intrinsically resistant to many antimycobacterial antibiotics, which presents serious problems in therapy. Here, we describe the development of a novel phenotype-based microscopic and computerized imaging drug screening approach. A pilot screen of 568 compounds from two libraries identified 17 hits. Eleven of these compounds are described for the first time as active against M. abscessus The impact of growth media on the activity of these compounds was tested, revealing that cation-adjusted Mueller-Hinton broth (MHII) supports better growth of actively replicating M. abscessus and improves the activity of associated compounds.

Abstract
![]()
Current tuberculosis
(TB) drug development efforts are not sufficient
to end the global TB epidemic. Recent efforts have focused on the
development of whole-cell screening assays because biochemical, target-based
inhibitor screens during the last two decades have not delivered new
TB drugs. Mycobacterium tuberculosis (Mtb), the causative
agent of TB, encounters diverse microenvironments and can be found
in a variety of metabolic states in the human host. Due to the complexity
and heterogeneity of Mtb infection, no single model can fully recapitulate
the in vivo conditions in which Mtb is found in TB patients, and there
is no single “standard” screening condition to generate
hit compounds for TB drug development. However, current screening
assays have become more sophisticated as researchers attempt to mirror
the complexity of TB disease in the laboratory. In this review, we
describe efforts using surrogates and engineered strains of Mtb to
focus screens on specific targets. We explain model culture systems
ranging from carbon starvation to hypoxia, and combinations thereof,
designed to represent the microenvironment which Mtb encounters in
the human body. We outline ongoing efforts to model Mtb infection
in the lung granuloma. We assess these different models, their ability
to generate hit compounds, and needs for further TB drug development,
to provide direction for future TB drug discovery.
