Over the last few years people have been interested in the process of singlet fission, owing to its relevance to solar cell technology. The energetics of singlet fission is intimately related to singlet-triplet (ST) gaps and energies of singlet excited states. However, accurate calculations of ST gaps in polyacenes are complicated due to near degeneracies in the π orbitals, and therefore, have been quite challenging. The spin-flip equation-of-motion coupled-cluster (SF-EOM-CC) and its perturbative ...

The geometric, thermodynamic, electronic and absorption properties of Pyrrole and some of its derivatives have been carried out using CCSD/6-311++G(d,p)/STO-3G, TD-DFT and DFT/B3LYP/6-31G(d) from monomer to five repeating units. Substitution by a methyl group at C3 and functional groups at C4 cause small changes in atomic distances. The estimated inter-ring bond length based on Badger's rule of 1.41 A indicates that the average structure is about 30% quinoid. The geometries indicates that strong ...

Peptidoglycan, the exoskeleton of bacterial cell and an essential barrier that protects the cell, is synthesized by a pathway where the final steps are catalysed by transpeptidases. Knowledge of the structure and function of these vital enzymes that generate this macromolecule in M. tuberculosis could facilitate the development of potent lead compounds against tuberculosis. This review summarizes the experimental and computational studies to date on these aspects of transpeptidases in M. tuberculosis ...

Mycobacterium tuberculosis is the causative agent of Tuberculosis. Formation of 3 → 3 crosslinks in the peptidoglycan layer of M. tuberculosis is catalyzed by l,d-transpeptidases. These enzymes can confer resistance against classical β-lactams that inhibit enzymes that generate 4 → 3 peptidoglycan crosslinks. The focus of this study is to investigate the catalytic role of water molecules in the acylation mechanism of the β-lactam ring within two models; 4- and 6-membered ring systems using two-layered ...

The anti-hyperglycemic potential of mannitol was investigated using different experimental models. Mannitol inhibited α-glucosidase (IC50 = 180 ± 20% w/v) and α-amylase (IC50 = 75 ± 20% w/v) activities in a dose dependent (2.5–20% w/v) manner, in vitro, although the effective doses are not gastrointestinally tolerable. Mannitol inhibited glucose absorption (IC50 = 19 ± 3% w/v) in isolated rat jejunum in ...
