Hydrogen bonding interactions like N–H⋯S, N–H⋯N and C–H⋯O helped to obtain either (<italic>Z</italic>)-selective anti-Markovnikov or Markovnikov Thiol–Yne-Click products exclusively with excellent yields from an internal alkyne under metal free conditions.
The health and economic burden of colitis is increasing globally. Understanding the role host genetics metagenomics essential to establish molecular basis pathogenesis. In present study, we have used a common composite dose DSS compare differential disease severity response in C57BL/6 (Th1 biased) BALB/c (Th2 mice with zero mortality rates. We employed multi-omics approaches developed newer vector analysis approach understand current report, comparative transcriptomics, metabonomics,...
We are reporting Co(ii) and Ni(ii) complexes of a pyridine containing aromatic macrocyclic triamide ligand, 3,6,9,15-tetraazabicyclo(9.3.1)pentadeca-1(15),11,13-triene-3,6,9-triacetamide (TPTA), as paramagnetic chemical exchange saturation transfer (paraCEST) MRI contrast agents. The synthesis characterization TPTA its reported. solution chemistry solid-state structure studied. Crystallographic data show that the [Co(TPTA)]·Cl2·2H2O complex (seven-coordinate, all four N atoms ring three...
A mechanistic investigation of molecular solar thermal energy release by solid-state cycloreversion dianthracenes to anthracenes reveals the integral roles chemical and physical transformations molecules towards total release.
Pathogenic infection is one of the major causes death in newborns.
Easily synthesizable tetrakis-(<italic>N</italic>-methyl-4-pyridinium)-porphyrin as a diaCEST agent that shows nearly pH independent good contrast in wide range of pH.
Paracetamol and a few other acetanilide derivatives are reported as special class of diamagnetic Chemical Exchange Saturation Transfer (diaCEST) MRI contrast agents, that exhibit only when the molecules form inter-molecular hydrogen bonding mediated molecular chains or sheets. Without protection their producing labile proton exchanges too quickly with solvent to produce any appreciable contrast. Through number variable temperature experiments we demonstrate under conditions bond network...
Abstract Higher organisms, especially mammals, harbor diverse microbiota in the gut that plays a major role maintaining health and physiological homeostasis. Perturbation of flora helps identifying their roles. Antibiotics are potent perturbing agents microbiome. Select antibiotics like vancomycin, neomycin, AVNM (an antibiotic cocktail containing ampicillin, metronidazole) were used to perturb C57BL/6 male mice understand roles host immunity metabolism. The current study revealed resulting...
A comparison of different diacetamide isomers shows the influence hydrogen-bonding networks in tuning diaCEST MRI contrast efficiency.
This study has been undertaken with an aim to investigate the suitability of deep eutectic solvents (DES)-based systems for magnetic resonance imaging studies. DESs are used develop systems, keeping in mind fact that these relatively less toxic than ionic liquids, and hence, DES based compound is expected be liquids. In this work, spin-lattice (T1 ) relaxation measurements carried out binary mixtures solvent a paramagnetic component choliniumtetrachloroferrate ([Ch][FeCl4 ]). Two cholinium...
Diagonal peak suppression of homonuclear multi-dimensional correlation NMR spectra is an area research that has seen a constant influx new methods designed to remove the intense but mostly redundant diagonal auto-correlation peaks. These methods, while at their job, aim retain intensity, position, lineshape, and sensitivity information-rich cross peaks as faithfully possible. Most these offer some alternative data acquisition scheme delivers same information original spectrum with suppressed...
Residue specific measurement of translational diffusion coefficient involving labile amide protons a protein molecule is known to give inconsistent result due multiple solute-solvent exchange events during the encoding period. The residues accessible solvent often overestimates contribution by fast diffusing molecules measured values. It has been, however, shown that this apparent drawback overestimation can become valuable source information about rates. An associated related never been...
