Twenty-seven formulations (RF1-RF27) for active layer (middle layer) were prepared by direct compression method using 33 Response surface method of polymers of different HPMC K4M, HPMC K15M and xanthan gum (low, middle, and high concentrations) by using Design of experiment software. Based on physico-chemical properties and drug release one formulation was chosen and formulated into extended release trilayered matrix tablets were by varying proportions of polymers by direct compression method and they were evaluated. The best optimized formulation was characterized for FTIR studies. Out of 27 active layer formulations, RF23 was chosen as best based with maximum drug release of 98.11% and was formulated into extended release trilayered matrix tablets (ARF23-HRF23) by varying proportions of polymers. The range of swelling index for all batches (ARF23-HRF23) was 82.34 to 97.46%, similarly the range of drug content was 95.49 to 99.11% and drug released in 24 hours sustainably over an extended period was 84.98 to 98.26% with all highest values exhibited by GRF23. The release order kinetics data indicate the zero-order release with highest (R2) = 0.983 for GRF23 better when compared to marketed product which followed first order showed R2 value 0.962. Further the formulation (GRF23) showed best fit to Korsmeyer-Peppas plots i.e., 0.957 indicating non Fickian (anomalous) transport coupled diffusion and erosion. The FT-IR data assure the compatibilityof drug and excipients. GRF23 was found to be stable for 180 days at accelerated conditions.","PeriodicalId":14278,"journal":{"name":"International Journal of Pharmaceutical Sciences and Drug Research","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90491330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pashanabheda is used as antiurolithiatic in Ayurveda. In the present study, flowers of A. lanata were selected for isolation of active constituents and screening for in vitro antiurolithiatic potentials, as literature supports that flowers have the highest quantity of natural components when compared with the other parts. Hydroalcoholic (80%-water, 20%-alcohol) extract of A. lanata flowers was prepared and fractionation with different organic solvents.. The two fractions (ethyl acetate and n-butanol) were subjected to isolation of active constituents using column chromatography technique, followed by purification of the isolated constituents by preparative high performance thin layer chromatography (HPTLC)and then the individual components were characterized by IR spectrophotometery. Finally, in vitro antiurolithiatic activity was screened by nucleation and aggregation assay. In the aggregation assay, gradual decrease in the calcium oxalate (CaOx) crystal nucleation as well as growth was observed by light microscopy. The findings of the nucleation assay indicate that phytoconstituents inhibited the crystallization of CaOx in solution. The size and the number of calcium oxalate crystals decreased with increasing concentration of the phytoconstituents. The increasing concentrations of Quercetin and betulin (100, 200, 300, 400 and 500 μg/mL) inhibited the CaOx crystal growth. The isolated quercetin and betulin from A. lanata have shown antiurolithiatic effect by significantly reducing the CaOx crystal growth.","PeriodicalId":14278,"journal":{"name":"International Journal of Pharmaceutical Sciences and Drug Research","volume":"192 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78532369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential activity of quinazolinone derivatives could be increased by substitution in position 3 of quinazolinone. Molecular docking of selective GABA activation was required to predict their antiepileptic activity. The molecular docking of quinazolinone derivatives was carried out using Autodock viva Ver.1.1.2.

Twenty quinazolinone derivatives showed the approximate docking score -7.1 to -9.3 kcal/mol. All twenty quinazolinone derivatives which value that have greater docking score compared to diazepam used as a standard compound.

FTIR measures the vibrations of bonds within the functional groups and yields a spectrum that can be considered as biochemical or metabolic fingerprint of the plant product. Using FTIR spectra, it is possible to find out the minor changes of primary and secondary metabolic characteristic functional groups which are responsible for their biological feature of the species. FTIR is a nondestructive, cost effective, user and eco-friendly tool. Pogostemon benghalensis, a wild relative of P. cablin, the highly utilized and adulterated medicinal herb by the native people for the extraction of essential oil Patchouli. The fresh leaves were subjected to hydro distillation for the extraction of the essential oils and were analyzed using the above techniques. The FTIR spectral lines have shown diverse unique peaks of functional groups. FTIR confirmed the volatile compounds and indicated by their functional groups of the essential oils such as C-H (Alkene), C-H (aromatic) and C=C. Similarly, the analysis proved the presence of alcohols, p-substituted alcohols or phenols, alkanes, alkynes, alkenes, aldehyde, ester, ether, aliphatic amines, carboxylic acids, aromatics, ketones, disulphide, alkyl halides, halogen, and nitro derivatives. The intensity and estimation of predominant volatiles were analysed by HPTLC, which showed 8 peaks with max Rf values ranged from 0.07 to 0.96. Further, the Eo was fractionated by with GC-MS technique and identified 41 volatile fractions in the oil. Thus, the obtained data provides the biochemical profiles with overlapping signals of a wide array of molecules that are present in the cells. So, the usage of essential oils in pharmacy, cosmetology and aromatherapy industries may be substantiated.
