The interaction of aminoglycosides with RNA represents a paradigm in the use of small molecules as effectors of RNA function. Aminoglycosides bind and affect the function of a variety of therapeutically useful RNA targets and show antimicrobial as well as antiviral activities. However, due to the complex nature of aminoglycosides, efforts for synthesizing(More)
Proteins are folded to form a small binding site for catalysis or ligand recognition and this small binding site is traditionally the target for drug discovery. An alternative target for potential drug candidates is the translational process, which requires a precise reading of the entire mRNA sequence and, therefore, can be interrupted with small molecules(More)
The emergence of extensively drug-resistant tuberculosis (XDR-TB) necessitates the need to identify new anti-tuberculosis drug targets as well as to better understand essential biosynthetic pathways. GlgE is a Mycobacterium tuberculosis (Mtb) encoded maltosyltransferase involved in α-glucan biosynthesis. Deletion of GlgE in Mtb results in the accumulation(More)
Peptide-based 1,2-dicarbonyl compounds have emerged as potent inhibitors for serine proteases. Herein, we have designed and synthesized d-arabinose and d-trehalose-based esters, alpha-ketoesters and alpha-ketoamides, and evaluated their inhibitory activity against Mycobacterium tuberculosis (Mtb) antigen 85C (ag85C), an acyltransferase in the serine(More)
GlgE is a bacterial maltosyltransferase that catalyzes the elongation of a cytosolic, branched α-glucan. In Mycobacterium tuberculosis (M. tb), inactivation of GlgE (Mtb GlgE) results in the rapid death of the organism due to a toxic accumulation of the maltosyl donor, maltose-1-phosphate (M1P), suggesting that GlgE is an intriguing target for inhibitor(More)
Long treatment times, poor drug compliance, and natural selection during treatment of Mycobacterium tuberculosis (Mtb) have given rise to extensively drug-resistant tuberculosis (XDR-TB). As a result, there is a need to identify new antituberculosis drug targets. Mtb GlgE is a maltosyl transferase involved in α-glucan biosynthesis. Mutation of GlgE in Mtb(More)
Correction for 'Synthesis of 2-deoxy-2,2-difluoro-α-maltosyl fluoride and its X-ray structure in complex with Streptomyces coelicolor GlgEI-V279S' by Sandeep Thanna et al., Org. Biomol. Chem., 2015, DOI: 10.1039/c5ob00867k.
Drug-resistant forms of Mycobacterium tuberculosis (M. tuberculosis) are increasing worldwide, underscoring the need to develop new drugs to treat the disease. One of the factors that make tuberculosis difficult to treat is the unique architecture of the mycobacterial cell wall. In this review, we catalogue the enzymes involved in the synthesis of the(More)
C-5-substituted triazole-oxazolidinones were synthesized using a bromide catalyzed cycloaddition between aryl isocyanates and epibromohydrin followed by a three-component Huisgen cycloaddition. The library of compounds was screened for antibacterial activity against Mycobacterium smegmatis ATCC 14468, Bacillus subtilis ATCC 6633, and Enterococcus faecalis(More)
