Abstract
Kinase enzymes play an important role in cellular proliferation, and inhibition of their activity is a major goal of cancer therapy. Protein kinase inhibitors as benzimidazole derivatives can be applied for prevention or treatment of cancers through inhibition of cell proliferation. To evaluate their protein kinase inhibitory effects, as well as the in silico study for active benzimidazole derivatives. Benzimidazole derivatives has presented significant therapeutic potential against several disorders and known to have numerous biological activities (such as antibacterial, antiviral and anti-inflammatory). Benzimidazole derivatives have shown significant potential in the reduction of viral load as well as in enhancing immunity. To forecast absorption, distribution, metabolism, excretion and toxicity, simply known as ADMET and the Lipinski rule of five parameters of the examined substances, the admetSAR and Swiss ADME were used. The ADMET predictions revealed that the compounds had good and safe pharmacokinetic features, making them acceptable for further development as therapeutic candidates in clinical trials. This study primarily focused on blocking 2 key targets of kinase proteins (CDK4/CycD1 and Aurora B). 2-Phenylbenzimidazole has shown the greatest inhibitory potential (with a binding energy of -8.2 kcal/mol) against protein kinase inhibitors. This study results would pave the potential lead medication for anticancer therapeutic strategies.

Abstract
Visualization of biomolecules in their native environment or imaging-aided understanding of more complex biomolecular processes are one of the focus areas of chemical biology research, which requires selective, often site-specific labeling of targets. This challenging task is effectively addressed by bioorthogonal chemistry tools in combination with advanced synthetic biology methods. Today, the smart combination of the elements of the bioorthogonal toolbox allows selective installation of multiple markers to selected targets, enabling multicolor or multimodal imaging of biomolecules. Furthermore, recent developments in bioorthogonally applicable probe design that meet the growing demands of superresolution microscopy enable more complex questions to be addressed. These novel, advanced probes enable highly sensitive, low-background, single- or multiphoton imaging of biological species and events in live organisms at resolutions comparable to the size of the biomolecule of interest. Herein, the latest developments in bioorthogonal fluorescent probe design and labeling schemes will be discussed in the context of in cellulo/in vivo (multicolor and/or superresolved) imaging schemes. The second part focuses on the importance of genetically engineered minimal bioorthogonal tags, with a particular interest in site-specific protein tagging applications to answer biological questions.

Abstract
Activity-based protein profiling (ABPP) is a powerful chemical approach for probing protein function and enzymatic activity in complex biological systems. This strategy typically utilizes activity-based probes that are designed to bind a specific protein, amino acid residue, or protein family and form a covalent bond through a reactivity-based warhead. Subsequent analysis by mass spectrometry-based proteomic platforms that involve either click chemistry or affinity-based labeling to enrich for the tagged proteins enables identification of protein function and enzymatic activity. ABPP has facilitated elucidation of biological processes in bacteria, discovery of new antibiotics, and characterization of host-microbe interactions within physiological contexts. This review will focus on recent advances and applications of ABPP in bacteria and complex microbial communities.

Abstract
Multicellular organisms require carefully orchestrated communication between and within cell types and tissues, and many unicellular organisms also sense their context and environment, sometimes coordinating their responses. This review highlights contributions from chemical biology in discovering and probing mechanisms of cell-cell communication. We focus on chemical tools for labelling proteins in a cellular context and how these can be applied to decipher the target receptor of a signalling molecule, label a receptor of interest in situ to understand its biology, provide a read-out of protein activity or interactions in downstream signalling pathways, or discover protein-protein interactions across cell-cell interfaces.

Abstract
Bacteria are ubiquitous lifeforms with important roles in the environment, biotechnology, and human health. Many of the functions that bacteria perform are mediated by proteins and enzymes, which catalyze metabolic transformations of small molecules and modifications of proteins. To better understand these biological processes, chemical proteomic approaches, including activity-based protein profiling, have been developed to interrogate protein function and enzymatic activity in physiologically relevant contexts. Here, chemoproteomic strategies and technological advances for studying bacterial physiology, pathogenesis, and metabolism are discussed. The development of chemoproteomic approaches for characterizing protein function and enzymatic activity within bacteria remains an active area of research, and continued innovations are expected to provide breakthroughs in understanding bacterial biology.

Abstract
Histidine kinases (HKs) are sensor proteins found ubiquitously in prokaryotes. They are the first protein in two-component systems (TCSs), signaling pathways that respond to a myriad of environmental stimuli. TCSs are typically comprised of a HK and its cognate response regulator (RR) which often acts as a transcription factor. RRs will bind DNA and ultimately lead to a cellular response. These cellular outputs vary widely, but HKs are particularly interesting as they are tied to antibiotic resistance and virulence pathways in pathogenic bacteria, making them promising drug targets. We anticipate that HK inhibitors could serve as either standalone antibiotics or antivirulence therapies. Additionally, while the cellular response mediated by the HKs is often well-characterized, very little is known about which stimuli trigger the sensor kinase to begin the phosphorylation cascade. Studying HK activity and enrichment of active HKs through activity-based protein profiling will enable these stimuli to be elucidated, filling this fundamental gap in knowledge. Here, we describe methods to evaluate the potency of putative HK inhibitors in addition to methods to calculate kinetic parameters of various activity-based probes designed for the HKs.

Abstract
Antibiotic resistance is a global and pressing concern. Our current therapeutic arsenal is increasingly limited as bacteria are developing resistance at a rate that far outpaces our ability to create new treatments. Novel approaches to treating and curing bacterial infections are urgently needed. Bacterial kinases have been increasingly explored as novel drug targets and are poised for development into novel therapeutic agents to combat bacterial infections. This review describes several general classes of bacterial kinases that play important roles in bacterial growth, antibiotic resistance, and biofilm formation. General features of these kinase classes are discussed and areas of particular interest for the development of inhibitors will be highlighted. Small molecule kinase inhibitors are described and organized by phenotypic effect, spotlighting particularly interesting inhibitors with novel functions and potential therapeutic benefit. Finally, we provide our perspective on the future of bacterial kinase inhibition as a viable strategy to combat bacterial infections and overcome the pressures of increasing antibiotic resistance.

Abstract
γ-Amido-modified 2'-deoxynucleoside triphosphates (dNTPs) and nucleoside triphosphates (NTPs) are becoming increasingly important as biological tools. We herein describe the simple and easy synthesis of γ-amido-dNTPs and -NTPs from commercially available corresponding dNTPs and NTPs in a one-pot reaction using water-soluble carbodiimide and ammonia solution. We examined the effects of synthesized γ-amido-dNTPs on the DNA polymerase reaction. The results obtained showed the incorporation of these derivatives into the DNA primer while maintaining nucleobase selectivity; however, their incorporation efficiency by DNA polymerase was lower than that of dNTP. This is the first study to demonstrate the successful synthesis of four sets of γ-amido-dNTPs and clarify their properties.

Abstract
The group III two-component hybrid histidine kinase MoHik1p in the filamentous fungus Magnaporthe oryzae is known to be a sensor for external osmotic stress and essential for the fungicidal activity of the phenylpyrrole fludioxonil. The mode of action of fludioxonil has not yet been completely clarified but rather assumed to hyperactivate the high osmolarity glycerol (HOG) signaling pathway. To date, not much is known about the detailed molecular mechanism of how osmotic stress is detected or fungicidal activity is initiated within the HOG pathway. The molecular mechanism of signaling was studied using a mutant strain in which the HisKA signaling domain was modified by an amino acid change of histidine H736 to alanine A736. We found that MoHik1pH736A is as resistant to fludioxonil but not as sensitive to osmotic stress as the null mutant ∆Mohik1. H736 is required for fludioxonil action but is not essential for sensing sorbitol stress. Consequently, this report provides evidence of the difference in the molecular mechanism of fludioxonil action and the perception of osmotic stress. This is an excellent basis to understand the successful phenylpyrrole-fungicides’ mode of action better and will give new ideas to decipher cellular signaling mechanisms.

Abstract
Modified nucleoside triphosphates (NTPs) are invaluable tools to probe bacterial enzymatic mechanisms, develop novel genetic material, and engineer drugs and proteins with new functionalities. Although the impact of nucleobase alterations has predominantly been studied due to their importance for protein recognition, sugar and phosphate modifications have also been investigated. However, NTPs are cell impermeable due to their negatively charged phosphate tail, a major hurdle to achieving live bacterial studies. Herein, we review the recent advances made to investigate and evolve bacteria and their processes with the use of modified NTPs by exploring alterations in one of the three moieties: the nucleobase, the sugar and the phosphate tail. We also present the innovative methods that have been devised to internalize NTPs into bacteria for in vivo applications.
