LC-MS/MS profiling and neuroprotective effects of Mentat® against transient global ischemia and reperfusion-induced brain injury in rats.

Objective: The aim of this study was to evaluate the possible beneficial effects of Mentat against transient global ischemia and reperfusion-induced brain injury in rats.

Methods: The neuroprotective effects of Mentat were evaluated against transient global ischemia and reperfusion (I/R)-induced brain injury in rats. Various neurobehavioral and biochemical parameters were assessed, followed by morphologic and histopathologic evaluation of brain tissue to conclude the protective effect of Mentat.

Ameliorative effect of Koflet formulations against pyridine-induced pharyngitis in rats.

In present study two formulations of Koflet (syrup and lozenges) were evaluated against pyridine-induced pharyngitis in rats. Topical application of 10% pyridine showed extravasation of Evans blue stain as a characteristic feature of on-going inflammation. In addition, the levels of TNF-α ( < 0.

Anticonvulsant activity of 1,2,3,4,6-penta-O-galloyl-β-D-glucopyranose isolated from leaves of Mangifera indica.

The present study was aimed to evaluate the anticonvulsant activity of 1,2,3,4,6-penta-O-galloyl-β-D-glucopyranose (PGG) isolated from methanolic leaf extracts of Mangifera indica in mice. Anticonvulsant activity of PGG was evaluated against pentylenetetrazole (PTZ)-induced and maximal electroshock (MES)-induced convulsions in mice. Additionally, locomotor activity and GABA levels in the brain were estimated to explore the possible CNS-depressant activity and mechanism behind the anticonvulsant activity, respectively.

(E)-Ethyl 2-cyano-3-(1H-pyrrol-2-yl)acrylate.

All the non-H atoms of the title compound, C(10)H(10)N(2)O(2), are nearly in the same plane with a maximum deviation of 0.093 (1) Å. In the crystal, adjacent mol-ecules are linked by pairs of inter-molecular N-H⋯O hydrogen bonds, generating inversion dimers with R(2) (2)(14) ring motifs.

8-Formyl-4-methyl-2-oxo-2H-chromen-7-yl 4-methyl-benzenesulfonate.

In the title compound, C(18)H(14)O(6)S, the coumarin ring system is nearly planar, with a maximum out-of-plane deviation of 0.032 (2) Å. The dihedral angle between the benzene ring and the coumarin ring system is 32.
