Biosynthesis of galactan in mycobacterium tuberculosis as a viable TB drug target?

While target-based drug design has proved successful in several therapeutic areas, this approach has not yet provided compelling outcomes in the field of antibacterial agents. This statement remains especially true for the development of novel therapeutic interventions against tuberculosis, an infectious disease that is among the top ten leading causes of death globally. Mycobacterial galactan is an important component of the protective cell wall core of the tuberculosis pathogen and it could provide a promising target for the design of new drugs. In this review, we summarize the current knowledge on galactan biosynthesis in Mycobacterium tuberculosis, including landmark findings that led to the discovery and understanding of three key enzymes in this pathway: UDP-galactose mutase, and galactofuranosyl transferases GlfT1 and GlfT2. Moreover, we recapitulate the efforts aimed at their inhibition. The predicted common transition states of the three enzymes provide the lucrative possibility of multitargeting in pharmaceutical development, a favourable property in the mitigation of drug resistance. We believe that a tight interplay between target-based computational approaches and experimental methods will result in the development of original inhibitors that could serve as the basis of a new generation of drugs against tuberculosis.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2682-49-7, help many people in the next few years.2682-49-7

Quantum chemical studies for some thiazolidinone derivatives using density functional theory

B3LYP/6-311G++(d, p) calculations have been carried out to study the structural and chemical properties of thioazilinone derivatives. The optimized molecular geometry of these derivative molecules are compared with the synthesized results of Mushtaque et al. The calculated results show that the density functional theory (DFT) can well reproduce the structure of the title compounds. Highest occupied-Lowest unoccupied molecular orbital (HOMO?LUMO) gap of the derivatives molecules are comparatively smaller then bare thiazolidinone. Natural bond orbital analysis for these title molecules shows strong delocalization of lone pair electrons from N, S, and O to the chemical bonds associated with central thiazolidinonering. The infrared intensites are calculated to compare with the FT-IR observation reported by Mushtaque et al. The experimental UV-Vis spectrum of present derivatives have been recorded and compared with calculated time dependent density functional (TDDFT) approach. The qualitative measures of chemical activeness of molecules have been presented in terms molecular electrostatic potential (MEP).

Crystal structures of two 1,3-thiazolidin-4-one derivatives featuring sulfide and sulfone functional groups

The crystal structures of two closely related compounds, 1-cyclohexyl-2-(2-nitrophenyl)-1,3-thiazolidin-4-one, C15H18N2O3S, (1) and 1-cyclohexyl-2-(2-nitrophenyl)-1,3-thiazolidin-4-one 1,1-dioxide, C15H18N2O5S, (2), are presented. These compounds are comprised of three types of rings: thiazolidinone, nitrophenyl and cyclohexyl. In both structures, the rings are close to mutually perpendicular, with interplanar dihedral angles greater than 80 in each case. The thiazolidinone rings in both structures exhibit envelope puckering with the S atom as flap and the cyclohexyl rings are in their expected chair conformations. The two structures superpose fairly well, except for the orientation of the nitro groups with respect to their host phenyl ring, with a difference of about 10 between 1 and 2. The extended structure of 1 has two kinds of weak C – H?O interactions, giving rise to a closed ring formation involving three symmetry-related molecules. Structure 2 has four C – H?O interactions, two of which are exclusively between symmetry-related thiazolidinone dioxide moieties and have a parallel ‘give-and-take-fashion’ counterpart. In the other two interactions, the nitrophenyl ring and the cyclohexane ring each offer an H atom to the two O atoms on the sulfone group. Additionally, a C – H?pi interaction between a C – H group of the cyclohexane ring and the nitrophenyl ring of an adjacent molecule helps to consolidate the structure.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2682-49-7 is helpful to your research. 2682-49-7

The optimization of the molecular structure, vibrational spectra and optical properties have been accomplished depends on the density functional theory (DFT) utilizing DMol3 and Cambridge Serial Total Energy Package (CASTEP) programs for [2aTZ] as the isolated molecule and crystal models. It’s very well-referred to the molecule’s structure and their contacts. They are equated with data calculated by means of various theoretical methodologies. [2aTZ]TF is fabricated by spin coating (250 ¡À 3 nm) and its optical properties (optical band gaps, Eg Opt, absorption index, k, reflective index, n, dielectric constant, epsilon, and optical conductivity,sigma) are also investigated. The high accurateness of the new [2aTZ] along with its suitable optical bandgap provided us to construct a photodetector and demonstrating its potential in optoelectronic implementations.

Native Chemical Ligation and Extended Methods: Mechanisms, Catalysis, Scope, and Limitations

The native chemical ligation reaction (NCL) involves reacting a C-terminal peptide thioester with an N-terminal cysteinyl peptide to produce a native peptide bond between the two fragments. This reaction has considerably extended the size of polypeptides and proteins that can be produced by total synthesis and has also numerous applications in bioconjugation, polymer synthesis, material science, and micro- and nanotechnology research. The aim of the present review is to provide a thorough mechanistic overview of NCL and extended methods. The most relevant properties of peptide thioesters, Cys peptides, and common solvents, reagents, additives, and catalysts used for these ligations are presented. Mechanisms, selectivity and reactivity are, whenever possible, discussed through the insights of computational and physical chemistry studies. The inherent limitations of NCL are discussed with insights from the mechanistic standpoint. This review also presents a palette of O,S-, N,S-, or N,Se-acyl shift systems as thioester or selenoester surrogates and discusses the special molecular features that govern reactivity in each case. Finally, the various thiol-based auxiliaries and thiol or selenol amino acid surrogates that have been developed so far are discussed with a special focus on the mechanism of long-range N,S-acyl migrations and selective dechalcogenation reactions.

Evaluation of hypoglycemic effects of 4-thiazolidinones

Nicotinic acid, a well-known hypolipidemic drug, is known to produce elevation of blood glucose in humans. In an earlier study in our laboratory, a thiazolidinone derivative of nicotinic acid was shown to exert hypolipidemic effect. The present study was aimed to find out if this compound produced any elevation of blood glucose in normal and diabetic Wistar rats. A closely related thiazolidinone was also evaluated. The two compounds reduced blood glucose in both normal and diabetic rats, while nicotinic acid produced hyperglycemia. The thiazolidinone structure with its hypoglycemic potential may be opposing the glucose elevating effect of nicotinoyl moiety. It is concluded from the study that the thiazolidinone derivative of nicotinic acid is a hypoglycemic agent besides being hypolipidemic. Detailed investigation is warranted.
