In the present investigation, 4-chloro acetophenone on condensation with 2-nitro benzaldehydes in methanolic NaOH solution yielded the corresponding chalcone. These chalcone were further reacted with Isonicotyl hydrazide and semicarbazide in ethanol which led to the formation of chalcone Isonicotyl hydrazone and chalcone semicarbazone derivatives respectively. The newly synthesized derivatives and there copper complexes were characterized on the basis of their chemical properties and spectroscopic data such as IR, NMR and UV. All newly synthesized compounds were evaluated for their antibacterial activities against E. coli and S. aureus also for antifungal activities against P....

The study was designed with an aim to evaluate the antiperoxidative potential of ascorbic acid on busulfan-induced lipid peroxidation. The study was performed in vitro using goat liver as lipid source. This evaluation was done by measuring the 4-hydroxy-2-nonenal (4-HNE) and nitric oxide (NO) content of liver tissue homogenates as markers of lipid peroxidation. The study reveals the lipid peroxidation induction capacity of busulfan and the antiperoxidative potential of ascorbic acid on busulfan-induced lipid...

The main objective of study was to formulate SEDDS of Spironolactone in order to achieve a better dissolution rate which would further help in enhancing oral bioavailability. SEDDS are isotropic mixtures of oils and surfactants, sometimes containing cosolvents. The present research work describes a Self Emulsifying Drug Delivery System (SEDDS) of Spironolactone using oils (Arachise oil, Oleic Acid, Castor oil, Soyabean Oil, Neobee M5, Migloyol, Capmul), surfactants (Tween-80, Cremophor RH40,Cremophor EL) and adsorbents (Aerosil-200,Avicel PH101,Lactose, Dextrose, Mannitol and Talc). In case of SEEDS of Spironolactone, the release rates of all oils were very rapid in Avicel PH101(above 82%) because it has the best flow property among the other absorbents. It Self Emulsifying Drug Delivery System observed that the release pattern from Arachis oil (92.95%), Oleic acid (90.21%) and Castor oil (97.54%) were better in comparison to other oils. Besides, it can be comprehend that the release rate of the three oils were very rapid in Tween-80(above 85%) because it has the best emulsifying property than Cremophor RH40 and Cremophor...

Epilepsy is a neurological disorder characterized by unprovoked, recurring seizures that disrupt the nervous system and can cause mental and physical dysfunction. Based on the ethnopharmacological information of the plant, the methanol and aqueous extract of the whole plant of MELISSA OFFICINALIS was evaluated for its antiepileptic activity in Swiss Albino Mice .Antiepileptic activity was assessed by using MES and PTZ induced models (250 and 500 mg/kg). Body weight doses were used for the present study. In the MES model the methanol and aqueous extracts showed a dose dependent reduction in the duration of hind limb extensor phase. In pentylenetetrazole induced model methanol and aqueous extracts at dose level of 500mg/kg body weight showed significant reduction in the tonic convulsions induced by PTZ when compared with control group. The results suggest a possible anticonvulsant effect of the methanol and aqueous extracts of Melissa officinalis inSwiss Albino...

The phytochemical analysis of the medicinal plant Kalonchoe pinnata was carried out to evaluate the antioxidant potential. Alcoholic extracts of the leaves was subjected to in vitro antioxidant activity screening models such as inhibition of lipid peroxidation, nitric oxide ,superoxide radical and hydroxyl radical scavenging activity. Ascorbic acid was used as the standard for superoxide anion radical scavenging activities. Butylated Hydroxy Toluene (BHT) is used as standard for anti-lipid peroxidation activity and for nitric oxide scavenging activity Gallic acid is used as a standard. In all the models studied, the extracts showed potent antioxidant activity, thereby augmenting it into the present day system of...
