Carbon Nanotubes in Pharmaceutical Nanotechnology: An introduction to Future Drug Delivery System

Recent discoveries indicate that the materials are bought down in sizes in the range 1-100nm, these exhibits unique electrical, optical, chemical and pharmaceutical properties. Methods have now been established to obtain the monodispersed nanocrystals of various metallic and semi conducting materials, single walled and multiwalled nanotubes of carbon and other metallic and non metallic materials together with organic nanomaterials such as nanostructures composites with tailored functionalities. Carbon nanotubes (CNTs) have great impact on the development of newer methodologies and devices useful for the analysis and the detection of various types of chemicals. The detection sensitivity can be increased many folds. The extraordinary properties of carbon nanotubes have led to demonstration of several applications of CNTs. But commercial realization of these CNTs and CNTs based devices require consistent quality of CNTs and these should be free of any impurity. Such demanding requirements need development of elaborate purification and sorting of CNTs. In last few years, Carbon Nanotubes (CNTs) have shown unexpected advantages in the field of cancer treatment and drug delivery systems. Present review article discuss in brief about the methods of synthesis, with purification as well as sorting techniques for giving different grades to different types of CNTs. These show very good adsorption properties which helps in the detection of various chemicals, toxic agents etc. Research done using CNTs for cancer treatment is also discussed in brief.

Quantitative analysis of civetone and normuscone in secretion from Viverricula indica and in aromatic remedies by gas chromatography-mass spectrometry

Image
ABSTRACT : The quantitation of civetone and normuscone in small Indian civet (Viverricula indica Desmarest) secretion cultivated in Thailand was analyzed by gas chromatography- mass spectrometry (GC-MS). Three main chemical constituents of small Indian civet secretion were civetone, dihydrocivetone and normuscone. The contents of chemical constituents were different between male and female secretion. Civetone (23.6 ± 1.5 µg/mg of secretion) was a major chemical constituent in the female secretion while normuscone (52.1 ± 5.9 µg/mg of secretion) was a major in the male secretion. Both civetone and normuscone were found in civet fur but not in the feces. Aromatic remedies which claimed to use the small Indian civet secretion as an ingredient showed both civetone and normuscone. Linearity range of civetone was 0-50 µg/ml with a correlation coefficient of 0.9717, and of normuscone was 0-80 µg/ml with a correlation coefficient of 0.9965. The average recoveries were 97.3-98.0% in sec...

Antimicrobial activity of aqueous, ethanolic, methanolic, cyclohexanic extracts and essential oil of Nigella sativa seeds

Image
  ABSTRACT : Most of the bacterial pathogens are resistant to existing synthetic antibacterial agents demanding an increasing effort to seek effective phytochemicals as antibacterial agents against such pathogens. Nigella sativa L. (black cumin) seeds play an important role in folk medicine and some of its major constituents are reported to be pharmacologically active. In this present work, Nigellasativa seed extracts were obtained using maceration extraction by various solvents (water, ethanol, methanol, and cyclohexan). The antibacterial and antifungal effects of different extracts and essential oil of seeds were investigated by the agar diffusion method against two gram positive (Bacillus subtilis CIP52.62 ,Staphylococcus aureus CIP4.83) and three gram negative strains of bacteria (Escherichia coli CIP53.126 ,Pseudomonas aeroginosa CIP82.118, Salmonella abony CIP80.39) and one strain of fungi (Candida albicans CIP48.72). All the extracts and essential oil showed varying d...

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
