A novel series of 2,5,6-trisubstituted imidazo[2,1-b][1,3,4]thiadiazoles 4 (a-d) and 7(a-i) were rationally designed through QSAR based pharmacophore approach and synthesized from 5-(1,3-benzodioxol-5-yl)-[1,3,4]thiadiazol-2-amine (1). The structures of these compounds were established by IR, 1H NMR, 13C NMR, HRMS technique. All the compounds were evaluated for their in vitro antihyperlipidemic activity using trition induced hyperlipidemic model. The newly synthesized title compound 7d, 7e and 7h showed a significant decrease in the serum, TCH, TG LDL and VLDL values along with an increase in serum HDL levels as compared to standard drug Fenofibrate. The treated groups also showed significant decrease in the atherogenic index, LDL:HDL risk ratios and the level of SGOT, SGPT and ALP activities compared to cholesterol induced hyperlipidemic control group. © 2013 Elsevier Masson SAS.

A series of 2,5,6-trisubstituted imidazo[2,1-b][1,3,4]thiadiazoles were synthesized, structures of the compounds were elucidated and evaluated for antitubercular activity against Mycobacterium tuberculosis H37Rv using microplate alamar blue assay (MABA) method, antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Vibrio cholera, and Escherichia coli by broth micro dilution assay method. Some compounds exhibited significant antibacterial and antitubercular activities. Compounds 10, 14, and 15 emerged as the most active molecules, showed significant antimicrobial activity and may serve as leads for further optimization. Graphical Abstract: Synthesis, spectral studies, and antibacterial and antitubercular activities of a novel series of imidazo[2,1-b][1,3,4]thiadiazole derivatives are described[Figure not available: see fulltext.]. © 2012 Springer Science+Business Media, LLC.

Gum ghatti (Anogeissus latifolia) or Indian gum is a complex non-starch polysaccharide. It has been widely employed in food, pharmaceuticals, paper and other industries primarily due to its excellent emulsification and thickening property. Other applications of gum ghatti are inadequately investigated owing to lack of information on it. Researchers in the recent years have shown a great interest in exploring its molecular structure and functional properties. This article is aimed at discussing the structural features, functional properties and applications of gum ghatti with an emphasis on its pharmaceutical potential. © 2011 Elsevier Ltd.

In this study, some novel 2,6-disubstituted imidazo[2,1-b][1,3,4] thiadiazoles 4 (a-i), 7 (a-p) and 11 (a-i) were synthesized from 5-substituted-1,3,4-thiadiazol-2-amine. The newly synthesized compounds 4a, 4b, 4c, 4e, 4g, 7j, 7l, 11b and 11c were evaluated in the National Cancer Institute for single dose in vitro primary cytotoxicity assay. Among the tested nine compounds, compound 4b (107166/760239) and 4c (107168/760240) were passed the criteria for activity in this assay and scheduled automatically for evaluation against the full panel of 60 human tumor cell lines at a minimum of five concentrations at 10-fold dilutions. 3-(2-(4-methoxyphenyl)imidazo[2,1-b][1,3,4] thiadiazol-6-yl)aniline (4c) exhibited significant in vitro anticancer activity against Non Small Cell Lung Cancer HOP-92 cell line (GI50: 0.114 μM) and Renal Cancer CAKI-1 cell line (GI50: 0.743 μM). © 2012 Elsevier Masson SAS.

Novel derivatives of 2-amino benzothiazoles 4(a-j) have been synthesized and tested for their antitumor activity using National Cancer Institute (NCI) disease oriented antitumor screen protocol against nine panel of cancer cell lines. Among the synthesized compounds, two compounds were granted NSC code and screened at National Cancer Institute (NCI)-USA for anticancer activity at a single high dose (10-5 M) and five dose in full NCI 60 cell panel. Among the selected compounds, 7-chloro-N-(2,6-dichlorophenyl)benzo[d]thiazol-2- amine (4i) with GI50 values of 7.18 × 10-8 M against Non-Small Cell HOP-92 Lung Cancer cell line proved to be the most active members in this study. Virtual screening was carried out through docking the designed compounds into the ATP binding site of epidermal growth factor receptor (EGFR) to predict if these compounds have analogous binding mode to the EGFR inhibitors. © 2012 Elsevier Masson SAS.

Peptic ulcer is a very common and painful disease now days. A plenty of treatment options are available but they have certain kinds of disadvantages and to overcome the problem the world is trying to explore more safe healing options such as herbal therapies. The present review work is an effort to gather the explored medicinal plants tested against ulcer and to identify the secondary metabolites which show curing effects against peptic ulcer, it was found that tannins, flavonoids and essential oils are more effective agents to care for peptic ulcer. © 2017, Association of Indian Pharmacist.

A simple, precise and accurate RP-HPLC method has been developed and validated for assay of Rivaroxaban. An isocratic separation was achieved using a phenomenex C18 (250×4. 6 mm, 5μm), 100°A particle size columns with a flow rate of 1 ml/min and using a PDA detector to monitor the elute at 250 nm. The mobile phase consisted of Methanol: Acetronitrile (50:50 v/v). The method was validated for specificity, linearity, precision, accuracy and robustness. The method was linear over the concentration range of 20-100 μg/ml (r2= 0. 99995). The method was found to be robust and suitable for assay of Rivaroxaban in a tablet formulation. The Drug Substance was subjected to Thermal and Photolytic Degradation. Degradation products resulting from the stress studies did not interfere with the detection of Rivaroxaban and the assay is thus stability-indicating.

The present study investigates the pharmaceutical application of hydrolyzed polyacrylamide grafted carboxymethylxyloglucan (HPam-g-CMXG), as promising polymeric material for the development of pH responsive microbeads. The graft copolymer was synthesized by conventional free radical polymerization method and saponified to enhance its functionality and characterized. An acute oral toxicity study ensured the bio-safety of developed copolymer for clinical application. Various batches of pH responsive spherical microbeads were developed and evaluated for the effect of process parameters on their overall performance. Result of in vitro drug release study (USP Type-II, paddle method) carried out in two different pH media (pH 1.2 and pH 7.4) showed a triphasic drug release pattern in all the formulations. Both the drug release and swelling of microbeads were significantly higher in simulated intestinal (alkaline) pH compared to simulated gastric (acidic) pH and this nature is desirable for targeted drug delivery. A strong correlation was observed between the process parameters and matrix composition and it directly influenced the drug transport mechanism. In conclusion, the hydrolyzed polyacrylamide grafted carboxymethylxyloglucan holds an immense potential to be explored pharmaceutically as new matrix material for the design of targeted drug delivery system. © 2014 Elsevier B.V.

A novel, simple, accurate, sensitive, reproducible, economical spectroscopic method was developed and validated for the determination of Azithromycin dihydrate and Cefixime trihydrate in combined dosage form. Second order derivative spectroscopy method is adopted to eliminate spectral interference. The method obeys Beer's Law in concentration ranges of 10-40 ppm for Cefixime trihydrate and 25-100 ppm of Azithromycin dihydrate. The method was validated for linearity, accuracy and precision as per ICH guidelines. The zero crossing point for Azithromycin dihydrate and Cefixime trihydrate was 328 nm and 231.6 nm, respectively in water. The LOD and LOQ value were found to be 0.13 and 0.38 ppm for Cefixime trihydrate and 0.80 and 2.44 ppm for Azithromycin dihydrate respectively. The developed and validated method was successfully used for the quantitative analysis of commercially available dosage form (ZIMNIC -AZ).
