Synthesis of some aldehyde derivatives of 1, 4 di- hydro pyridine has been done. The entire synthesized compounds were characterized by UV, IR and 1HNMR spectroscopy. The anticonvulsant and antimicrobial activity were also evaluated. The present investigation deals with the synthesized compounds possessing good anticonvulsant, analgesic and antimicrobial activity. Synthesized compounds like PNH, PNA, ONF, MND, PAH posses significant anti convulsant activity. However, all the compounds showed analgesic activity less than the reference standard. Anti bacterial activities of the compounds were evaluated against staphylococcus aureus and the zone of inhibition was measured as the parameter of activity. Amikacin, the standard showed a zone of inhibition of 18 mm out of 8 synthesized compounds only one PNN (Ia) compound showed an equal activity when compared with standard. In which (ONF, PAN) showed considerable anti bacterial activity. The remaining four compounds PNM, MNC, MNA, PAK showed moderate antibacterial activity. Anti bacterial activity of the compounds were evaluated against E. Coli and the zone of inhibition was measured as the parameter of...

The study is aimed at development of physicochemical parameters and to investigate the active principle present in Tridax Procumbens Linn. Tridax Procumbens Linn. (Asteraceae) commonly known as Coat Buttons is an important plant used against various disorders in indigenous system of medicine such as Wound-Healing, Hepatoprotective, Anti-Inflammatory, Anti-diabetic and Immunomodulatory activities. Thus from the extensive literature survey it was revealed that no reports were available on microscopic evaluation, standardization parameters and chemo profile of Tridax Procumbens to check the identity and purity of the drug. The present work embodies the investigations carried out to establish methods for quality control of drugs as per WHO guidelines: complete botanical evaluation which comprises macroscopic, microscopy physicochemical parameters like loss on drying extractive value, ash value and to investigate the Phytochemical present the extract in the preliminary level were carried out for the quality control of the drug. Thus it was thought worthwhile to explore this endangered plant on the basis of this standardization parameter. The study will provide referential information for the...

Alzheimer’s disease, a synonym for life threatening dementias is characterized by oxidative stress and neuroinflammation induced neuronal loss, impaired energy metabolism, and cholinergic deficit leading to severe cognitive impairments and other abnormal neuropsychiatric changes. Cholinergic hypothesis is the most accepted theory explaining pathology of AD and Acetylcholinestrase inhibitors are the main stay of AD therapy. In the present study, the effect of Minocycline, a tetracycline derivative, was investigated against intracerebroventricular streptozotocin induced cholinergic deficits. Intracerebroventricular administration of streptozotocin (3mg/kg) bilaterally on day 1 and 3 was able to produce significant cholinergic deficits as evidenced by increase in level of acetylcholinestrase while chronic treatment with Minocycline (10, 20 and 40mg/kg, i. p.) for 21 days significantly decreased it. The results of the present study support the candidature of Minocycline in learning and memory disorders resembling dementia of Alzheimer’s...

The anti-allergic of an aqueous extract of the leaves of Ailanthus excelsa Roxb.(AELAq) was evaluated by using milk induced leucocytosis and eosinophilia in mice, passive paw anaphylaxis in rats models while the anticataleptic properties was evaluated by Clonidine induced catalepsy in mice mode. The extract significantly (*p<0.05, **p< 0.01) decreased the leucocytosis and eosinophilia along with passive paw anaphylaxis in the above experimental animals respectively. The extract also significantly (**p< 0.01) decreased Clonidine induced catalepsy in mice. These results suggest that aqueous extract AELAq may have the potential therapeutic value in the treatment of allergic diseases and to produce adaptogenic properties....

The aim of the present research work is to evaluate the impact of superdisintegrants in the formulation and evaluation of rapidly disintegrating tablets. In the present study, Loratadine is the model drug. Rapidly disintegrating tablets of Loratadine was prepared by direct compression method. In this method the different excipients used were Calcium Silicate (FM1000), Pharmattose DCl-21 (anhydrous lactose), Citric acid(anhydrous), Colloidal Silica (Aerosil), Sodium stearyl fumarate, Magnesium Stearate, Crosscarmellose Sodium (AcDiSol), L-HPC( Low substituted hydroxyl propyl cellulose), Microcrystalline Cellulose (Avicel pH-200), Aspartame, Orange flavor and Strawberry flavor. The formulations containing Crosscarmellose sodium and Low substituted hydroxyl-propyl-cellulose as superdisintegrants, disintegrated faster compared to the formulation containing Microcrystalline Cellulose (Avicel pH-200). Pre compression and post compression parameters were evaluated for all eight formulations (F1-F8).Infra-Red study revealed that all polymers and excipients used were compatible with the drug. In vitro drug release showed that almost drug was release in the range of 94-97% range in 10 minutes. Depending upon cumulative drug release, in vitro disintegration time, wetting time results, one formulation F8...
