Persimmon (Diospyros kaki Linn.), which belongs to the Ebenaceae family, have numerous bioactive compounds such as polyphenols, dietary fiber, carotenoids and minerals. This fruit possesses hypolipidemic and antioxidant properties and can be used in anti-atherosclerosis diets. The present paper reveals the phytochemical screening, Antioxidant, Anti-inflammatory activity and GC-MS Spectral analysis of the isolated fatty acids compounds of the plant Diospyros kaki. From the Antioxidant and Anti-inflammatory activity the chloroform fraction of ethanolic extract showed the good activity and proceeded for isolation. Six fatty acid compounds were isolated from the plant Diospyros kaki and analyzed using Gas chromatography-Mass Spectrometry. From the analysis 13 compounds were identified by comparing their retention time and peak area with that of literature and interpretation of mass spectra. The major phytoconstituents were Spiro [(tricyclo [6.2.2.0(2, 7)] dodeca and 1- monolinoleoylglycerol trimethylsilyl ether. Hence this study creates a platform to screen many bioactive components to treat many...

Background and aim: Spiroazetidin-2-ones and furans are commonly used as anti-bacterial, anti-fungal, anti-inflammatory, cardiovascular activities, anticancer, antiparkinson agents etc. The purpose of this study was to perform virtual toxicity studies of the synthesized compounds 1-(substitutedphenyl)-3-chloro-5,9-bis(furan-2-ylmethylidene)-1-azaspiro[3.5]nonan-2-ones (3a-3h). Materials and methods: Computational toxicology and mutagenicity profiles of these compounds were generated by using TOPKAT 6.1 (Toxicity Prediction Komputer Assisted Technology version 6.1). The molecular structure of the query compound was given as a SMILES string and a desired TOPKAT predictor was selected, then TOPKAT automatically conducts analysis of the query compound. Results: According to TOPKAT 6.1 model the compounds 3a – 3h are non-mutagenic and devoid of aerobic biodegradability. The computed Rat oral LD50 values for the compounds 3a – 3h ranged from 1.1g/kg to 115.0mg/kg. These high LD50 values suggest higher safety of these compounds. The computed probability of skin irritation for all compounds was found to be 1.000 and the probability for the carcinogenicity was found to be 0.950-1.000. Conclusion: By using computerized statistical methodology, more promising molecules can...

This study was aimed to investigate the biochemical influence of aqueous extracts of roots, stem and leaves of Zizyphus mauritiana (ZM) on silica induced toxicity in rats, with changes in inflammatory markers in liver and kidney. To test the preventive effect of extracts of Zizyphus mauritiana on development of silica induced toxicity in wistar albino rats, animals were treated simultaneously with intraperitoneal administration of silica and oral feeding of extracts, for 21 days. At the end of the experiment, blood samples were withdrawn for biochemical analysis. The results revealed that animals administered with silica and simultaneous feeding of extracts of root, stem and leaves of Zizyphus mauritiana had a significant effect and decreased serum levels of ALT, AST, ALP, urea, uric acid, creatinine and LDH, as well as pro-inflammatory cytokines TNF-α and IL-6 as compared with normal control group. Zizyphus mauritiana extracts treated groups had shown recoupment in the body weight which was found decreased in only silica treated animals. In conclusion, this study indicated that extracts of bark...

The purpose of the study is to evaluate the effect of the granulation properties of Lactose depending upon the use of its crystalline forms and the impact of active (Acetaminophen) concentration using rheological and thermal tools. Lactose was chosen as an excipient available in different hydrate forms (anhydrous and monohydrate) and Acetaminophen (APAP) was selected as a model drug for the subject research. Preliminary research was performed to determine wet-granulation end-point utilizing a real time off-line PAT tool, thermal effusivity. Further research was continued for low-shear wet granulation for the powder blends of drug and excipients. The properties of wet and dried granulation were determined using Powder Rheometer, Thermal effusivity and DSC. The dried granules crushing strength were evaluated using Texture Analyzer. Acetaminophen is a strong cohesive active, which upon wet granulation was found to bind strongly with Lactose particles to form more flowable and compressible granular mass. The granulation prepared using anhydrous form of Lactose with APAP showed higher bulk density and permeability as compared to hydrate form...

Cefixime trihydrate belongs to third generation cephalosporin having poor water solubility. In the present study, nanocrystal suspensions of cefixime trihydrate were prepared with the objective of providing enhanced solubility and stability with reduced particle size and thus improving the bioavailability potential. Nanocrystal suspensions were prepared by high pressure homogenization technique and evaluated for particle size, polydispersity index, zeta potential, and drug release. 23 factorial design was used for the formulation designing purpose. Particles of average size 143.5nm having PDI of 0.269 were produced. Zeta potential was found to be -36.6mV and the formulation was found stable on the basis of results obtained from differential scanning calorimetry and scanning electron microscopy studies. The drug release and ex-vivo permeation studies revealed enhanced permeation of drug, as desired, indicating its potential for an attempt towards successful nanocrystal...
