Synthesis of 2-Ethylhexyl 5-Bromothiophene-2-Carboxylates; Antibacterial Activities against Typhi, Validation via Docking Studies, Pharmacokinetics, and Structural Features Determination through DFT.

A new class of thiophene-based molecules of 5-bromothiophene-2-carboxylic acid () have been synthesized in current research work. All analogs - were synthesized with optimized conditions by coupling reactions of 2-ethylhexyl 5-bromothiophene-2-carboxylate () with various arylboronic acids. The results indicated that the majority of compounds showed promising effective in vitro antibacterial activity.

Expression studies of stress responsive genes in cotton Gossypium hirsutum L.

Background: Cotton is the world's richest source of natural fiber. Meanwhile cotton plant is top ranked stress sensitive plant thereby affecting its yield and fiber quality. But, in climate change scenario, fiber yield and quality are being affected due to environmental stresses, especially heat, drought and salinity.

Computations of the M-Polynomials and Degree-Based Topological Indices for Dendrimers and Polyomino Chains.

Topological indices correlate certain physicochemical properties like boiling point, stability, and strain energy of chemical compounds. In this report, we compute M-polynomials for PAMAM dendrimers and polyomino chains. Moreover, by applying calculus, we compute nine important topological indices of under-study dendrimers and chains.

Computational Analysis of topological indices of two Boron Nanotubes.

There has been a recent debate that boron nanotubes can outperform carbon nanotubes on many grounds. The most stable boron nanotubes are made of a hexagonal lattice with an extra atom added to some of the hexagons called ∝-boron nanotubes. Closed forms of M-polynomial of nanotubes produce closed forms of many degree-based topological indices which are numerical parameters of the structure and determine physico-chemical properties of the concerned nanotubes.

M-Polynomials and Degree-Based Topological Indices of the Crystallographic Structure of Molecules.

Topological indices are numerical parameters used to study the physical and chemical properties of compounds. In quantitative structure⁻activity relationship QSARs, topological indices correlate the biological activity of compounds with their physical properties like boiling point, stability, melting point, distortion, and strain energy etc. In this paper, we determined the M-polynomials of the crystallographic structure of the molecules Cu₂O and TF₂ [].
