Objective: The scope of the present study was the preparation and characterization of a novel composite acrylamide β-cyclodextrin grafted 3-aminopropyltriethoxysilane bentonite (AMCD-g-APSB), for the controlled delivery of curcumin (CUR).Methods: AMCD-g-APSB, was synthesized by solvent-free conditions using microwave irradiation. The structure and surface morphology of the composite was established using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermal analysis, etc.Results: The swelling percentage of the composite depends on both time and pH of the medium. The maximum swelling of the composite occurred at a pH of 7.4. The maximum drug encapsulation was occurring at a pH 3. About 96.5% of drug was loaded at pH 3. In vitro biocompatibility study was performed, and the result showed good biocompatibility of the composite in the concentration range 2.5–50 μg/ml.Conclusions: Drug delivery study of the composite proved that CUR could be successfully released in a controlled manner in the colon without much loses of the drug in the stomach.

Aim: To synthesize and evaluate 4-aminoantipyrine related schiff’s bases as antibacterial agents. Objective: To synthesize, purify, characterize and evaluate 4-aminoantipyrine. Method: Schiff bases derived from 4-aminoantipyrine play a vital role in biological and pharmacological activities. Knowing the importance of 4-aminoatipyrine schiff bases and their analogues wide varieties of bioactivities like analgesic, antiviral, antipyretic, anti-rheumatic, antimicrobial and anti-inflammatory activities have been widely studied. 4-aminoantipyrine compounds C1 (anisaldehyde), C2 (p-hydroxybenzaldehyde) and C3(vanillin) were prepared by condensation between 4-amino antipyrine and substituted aromatic benzaldehydes. The products were purified by recrystallization by using ethanol, characterized by IR spectroscopy. The N-H stretching in 4-aminoantipyrine is shown at 3430 cm-1 and -3325 cm-1. The -HC=N- stretching is observed in the range of 1508-1504 cm-1 The –OCH3 stretching is found at 1888 cm-1. 4-amino antipyrine related schiff’s bases evaluated their activity as antimicrobials in-vitro by spread plate method against E.coli. Schiff bases have potent antibacterial activity with gram negative bacteria E.coli. Results: Synthesis and characterization of a schiff bases derived from substituted benzaldehydes and 4-aminoantipyrine was evaluated and characterized with the IR spectroscopic techniques and schiff bases have shown potent antibacterial activity against E.Coli.

Objectives: The present study was aimed to investigate the facile synthesis of silver nanoparticles (AgNPs) using the green gram sprout extract (GGSE) of Vigna radiata L. and also in vitro studies of antioxidant and antimicrobial activities. Methods: Gas chromatography-mass spectroscopy techniques have been used for the qualitative and quantitative evaluation of the phytochemicals present in the green gram seedlings. The antioxidant activity of AgNPs and GGSE was analyzed using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. In vitro antibacterial activity was performed using the agar well diffusion method. Results: The presence of various secondary metabolites such as flavonoids, steroids, terpenoids, alkaloids, amino acids, polyphenol, glycoside, and protein was found in samples. The major chemical compounds of V. radiata were n-hexadecanoic acid, stigmasterol, caffeine, hexadecanoic acid, cholest-5-en-3-ol (3.beta.)-, and cyclopentane. The percentage of DPPH activity was enhanced on increasing the concentration of AgNPs. In vitro antibacterial effect of the diverse concentrations of AgNPs was investigated against each Gram-negative (Klebsiella aerogenes, and Escherichia coli) and Gram-positive (Bacillus substilis and Staphylococcus aureus) bacterial strains. Conclusion: The result suggests that biosynthesized AgNPs have good antibacterial and antioxidant activity and might be a potential for the bioactive components.
