Purpose: To develop mucoadhesive patches for buccal administration of metoprolol succinate and to evaluate their in vitro and in vivo bioadhesion. Methods: The mucoadhesive buccal patches were prepared by solvent casting technique using two different mucoadhesive polymers. The formulations were tested for in vitro drug permeation studies, buccal absorption, in vitro drug release studies, moisture absorption as well as for in vitro and in vivo bioadhesion. Results: The peak detachment force and work of adhesion for MC5 (sodium carboxymethylcellulose, i.e., Na CMC) patch were 0.87 N and 0.451 mJ respectively and the corresponding values for CH5 (chitosan) were 5.15N and 0.987 mJ. Formulation CH5 (prepared with chitosan) showed 67.1 % release, while MC5 (Na CMC) showed drug release of 81.9 % in 6 h. Basic pharmacokinetic parameters such as Cmax, Tmax and AUCtotal varied statistically (p < 0.05) when given by the buccal route compared with that of the solution given by the oral route. Conclusion: The results indicate that formulation of suitable bioadhesive buccal patches with the desired permeability is feasible. The development of bioadhesive buccal formulation for metoprolol succinate with a lower dose and few side effects may be attainable. © Pharmacotherapy Group. All rights reserved. Source

The high potential of quinazolinone containing natural products and their derivatives in medicinal chemistry led us to discover four novel series of 53 compounds of quinazolinone based on the concept of molecular hybridization. Most of the synthesized analogues exhibited potent leishmanicidal activity against intracellular amastigotes (IC50 from 0.65 ± 0.2 to 7.76 ± 2.1 μM) as compared to miltefosine (IC50 = 8.4 ± 2.1 μM) and nontoxic toward the J-774A.1 cell line and Vero cells. Moreover, activation of Th1 type and suppression of Th2 type immune responses and induction in nitric oxide generation proved that 8a and 8g induce murine macrophages to prevent survival of parasites. Compounds 8a and 8g exhibited significant in vivo inhibition of parasite 73.15 ± 12.69% and 80.93 ± 10.50% against Leishmania donovani/hamster model. Our results indicate that compounds 8a, 8g, and 9f represent a new structural lead for this serious and neglected disease. © 2013 American Chemical Society. Source

Recycling generally means reuse of waste water back in the same cycle where it is generated. The world's water is a finite and valuable resource. Wastewater recycling systems can play a major role in this approach and can potentially provide a range of sustainable development over conventional sewerage systems and on so many systems. Wastewater recycling is important due to many environmentally benefits which are Public health requirements; Environmental requirements; Appropriate technology selection; and Management system development. The water recycling process utilizes physical, biological and chemical principles to remove adulterate from water. Exploit of mechanical or physical systems to treat waste water is generally referred to as primary treatment and by biological processes to provide further treatment is referred to as secondary treatment and after all additional purification is called tertiary or advanced treatment. Recycling saves energy reduces raw material extraction and takes action on climate change. This article shows how wastewater is treated and recycled and reused is beneficial for us and also for environment. This also explores the complex relationship between waste recycling and its impacts. To obtain the full benefit we need to manage and protect it. After study we have founded that recycling is better for the environment. © Research India Publications. Source

Context: Cleome viscosa Linn. (Capparidaceae) is used traditionally in the Indian system of medicine as a carminative, anthelmintic, and diuretic, and used for healing wounds, ulcers and diarrhea. Objective: A 70% ethanol (EtOH) extract of the aerial parts of Cleome viscosa extract (CVE) was investigated for gastroprotective activity in different gastric ulcer models in order to validate ethnobotanical claims regarding the plant use in ulcers. Materials and methods: CVE (100, 200 and 400mg/kg body weight) was administered orally, twice daily for 5d, for prevention from EtOH, pylorus ligation (PL) and cold restraint stress (CRS)-induced ulcers in rats. Estimation of H+K +ATPase activity and gastric wall mucous were performed in EtOH-induced ulcer, antioxidant enzyme activities in supernatant mitochondrial fraction of CRS-induced ulcer, and gastric secretion parameters were estimated in PL-induced ulcer model Results: CVE showed significant (p<0.01) dose-dependent inhibition of lesion index in EtOH 15.93-42.30%, PL 26.34-59.28% and CRS 22.58-54.03%, respectively. CVE prevents the oxidative damage of gastric mucosa by blocking lipid peroxidation and by a significant (p<0.001) decrease in superoxide dismutase, and an increase in catalase activity. A significant (p<0.01) decrease occurred in the level of H+K +ATPase, volume of gastric juice and total acidity. Simultaneously, the level of gastric wall mucus and pH were increased significantly (p<0.05). High performance thin layer chromatography analysis showed the presence of quercetin and gallic acid (0.3% and 0.25% w/w, respectively) in CVE. Conclusions: Results of our study showed that C. viscosa possesses significant gastroprotective activity, probably due to free radical scavenging activity, and validates the folklore claim. © 2013 Informa Healthcare USA, Inc.

Twelve new 3-(4-substituted benzyl)-5-(4-substituted phenyl)-1-phenyl-4, 5-dihydro-1H-pyrazole derivatives were synthesized by reacting 1-(4-substituted phenyl)-4-(4 substituted phenyl) but-3-en-2-one and phenyl hydrazine in ethanol. 1-(4-substituted phenyl)-4-(4 substituted phenyl) but-3-en-2-one were synthesized by condensation of substituted phenylacetone and substituted benzaldehyde in NaOH solution. The synthesized compounds were confirmed by spectra data. The compounds were evaluated in-vitro for their antibacterial, antifungal, anti-tubercular activity and in-vivo for their anti-inflammatory activity. Compounds P25, P29, P31 and P 32 were found to exhibit good antimicrobial and anti-inflammatory activity. Source
