Quinazolino-benzothiazoles: fused pharmacophores as anticonvulsant agents.

A series of 6-bromo-2-ethyl-3-(substitutedbenzo[d]thiazol-2-yl)quinazolin-4(3H)-one 3 (a-j) were synthesized using appropriate synthetic route and evaluated experimentally by the Maximal Electro Shock (MES) and the PTZ-induced seizure methods. Among the tested compounds, 3-(benzo[d]thiazol-2-yl)-6-bromo-2-ethylquinazolin-4(3H)-one (3a) has shown significant activity against tonic seizure by the MES model and 6-bromo-2-ethyl-3-(6-methoxybenzo[d]thiazol-2-yl)quinazolin-4(3H)-one (3h) against clonic seizure by PTZ-induced seizure model. Not one of the selected compounds demonstrated any sign of neurotoxicity and hepatotoxicity.

Evaluation of sedative and anticonvulsant activities of Unmadnashak Ghrita.

'Unmadnashak Ghrita' (UG) is a ayurvedic formulation containing Ferula narthex (6 g), Gardenia gummifera (6 g), Ellataria cardamom (6 g), Bacopa monneri (6 g), and cow's ghee (clarified butter fat) (76 g). In the present study, neuropharmacological activities of UG were evaluated for its gross behavioural effect, pentobarbitone sleeping time, spontaneous locomotor activity, antagonism to amphetamine induced hyperlocomotor activity, analgesic activity by tail flick test, rota-rod performance (motor coordination test), maximal electroshock (MES) induced seizures, and pentylenetetrazol (PTZ) induced convulsions in mice. The formulation showed CNS-depressant activity in gross behavioural test, potentiated pentobarbitone sleeping time and there was significant decrease in spontaneous locomotor count in mice.

Neuropharmacological actions of panchagavya formulation containing Emblica officinalis Gaerth and Glycyrrhiza glabra Linn in mice.

A panchagavya Ayurvedic formulation containing E. officinalis, G. glabra, and cow's ghee was evaluated for its effect on pentobarbital-induced sleeping time, pentylenetetrazol-induced seizures, maximal electroshock-induced seizures, spontaneous motor activity, rota-rod performance (motor coordination) and antagonism to amphetamine in mice.

Evaluation of hepatoprotective effect of Amalkadi Ghrita against carbon tetrachloride-induced hepatic damage in rats.

Amalkadi Ghrita (AG), a polyherbal formulation, was evaluated for its hepatoprotective activity against carbon tetrachloride (CCl4)-induced hepatic damage in rats. The hepatoprotective activity of AG was evaluated by measuring levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), and acid phosphatase (ACP). The serum levels of total proteins and bilirubin were also estimated.
