BACKGROUND
Epilepsy is one in every of the foremost important chronic neurological disorders with high incidence worldwide. Several epileptic patients don't seem to be fully treated with currently available marketed medicines likewise so many drugs have shown unfavorable side effect and drug
In doses of 160 and 80 mg/kg, isatin (2,3-dioxoindoline) significantly reduced the total incidence of audiogenic epileptic seizures in rats highly sensitive to an acoustic epileptogenic stimulus. The number of severest forms of seizure (running, clonic convulsions) was higher than in the control
Isatin (indole-2, 3-dione) is an endogenous compound with anxiogenic properties, which occur within a narrow dose range (15-20 mg/kg, i.p.). Dose increment beyond 50 mg/kg, i.p. leads to the loss of anxiogenesis. Since a link has been postulated between anxiogenic and convulsant activity, the effect
In the present study, anticonvulsant activity of hydrazones, Schiff and Mannich bases of isatin were evaluated by maximal electroshock method (MES) and metrazol-induced convulsions (MET) at 30, 100 and 300 mg/kg dose levels. Neurotoxicity of the compounds was also assessed at the same dose levels.
Isatin (indole-2,3-dione) has been found in mammalian tissues as one of major components of tribulin, a postulated endogenous marker of stress and anxiety. I previously identified isatin as an endogenous inhibitor of monoamine oxidase (MAO) in the human urine and the brain of stroke-prone
In the present work, some new 5-[2(3)-dialkylamino alkoxy] Indole 3-thiosemicarbazone 2-ones and 5-[2(3)-dialkylamino alkoxy] Indole 3-hydrazone 2-one were prepared from 5-hydroxy isatin. The structures of the products were characterized by IR, NMR, and MASS Spectral studies. All the compounds were
Brain tribulin activity in rats with an inherited predisposition to audiogenic epilepsy was studied after seizures of different intensity were induced by an electric bell. Weak seizures (from 0 to 2 arbitrary units) did not produce any changes in endogenous inhibitory activity towards either
OBJECTIVE
A series of substituted isatin semicarbazones and related bioisosteric hydrazones were designed and synthesised to meet the structural requirements essential for anticonvulsant properties.
METHODS
The structures of all synthesised compounds were confirmed by means of infrared, proton
A series of 2-(substituted-phenyl)-3-(2-oxoindolin-3-ylidene)amino)-thiazolidin-4-one derivatives were designed and synthesized under microwave irradiation, using an eco-friendly, efficient, microwave-assisted synthetic protocol that involves cyclocondensation of 3-substituted
Due to resistance of some epileptic patients to the current medications and the general incidence of severe side effects of these drugs, development and discovery of novel antiepileptic drugs is crucial. Isatin-based derivatives are promising compounds as antiepileptic agents. In this study a new
In this study a new series of 3-aryloxy/arylthioxyacetylhydrazono-2-indolinones obtained by condensation of isatin with aryloxy/arythioxyacetylhydrazines were treated with morpholine and formaldehyde to yield 1-morpholinomethyl-3-aryloxy/arylthioxyacetylhydrazono-2- indolinones. Structures of all
The influence of the local anesthetics procaine and lidocaine on the anticonvulsant action of propranolol was investigated using the maximal electroshock seizure test in mice. Combined application markedly reduced ED50 values either of the local anesthetics or of propranolol. Selected
In the present study a series of new N(4)-(4-substituted benzylidene)-N(1)-([1,3,4]thiadiazino [6,5-b]indol-3-yl)semicarbazide (1-6), N(4)-([1,3,4]thiadiazino[6,5-b]indol-3-yl)-N(1)-(1-(4-substituted phenyl)ethylidene)semicarbazide (7-10),
