Objectives: 1,3,4-thiadiazole (A), 1,3,4-oxadiazole (B) and 1,2,4-triazole (C) derivatives have been known for their immense pharmacotherpaeutic potential. The current research article attempts to further explore and understand the probable biochemical mechanism related to anti-inflammatory activity of derivatives. Methods: The screened A, B and C derivatives were investigated for both in-vitro (Erythrocyte Membrane stabilization activity, Proteinase enzyme inhibitory activities) and in-vivo correlation using acute and chronic anti-inflammatory potential by carrageenan induced rats paw edema and cotton pellet granuloma methods respectively. The activity was studied after interpreting acute toxicity studies results. Results: In vitro studiesin the case of Erythrocyte Membrane stability and Proteinase enzyme inhibitory activities exhibited by A, B, and C at 100 ppm were found to be 48.89%, 51.08% and 50.08% and 66.78%, 76.91% and 57.41% respectively. The maximum toxic dose was found to be 2000 mg/kg. The derivatives were studied for two-dose levels viz; Lower (100 mg/kg) and higher dose (200 mg/kg). In rat paw edema maximum decrease was obtained for A (50.05%), B (50.05%) and C (51.06%) at lower and higher dose at 68.76%, 55.61%, and 65.26% respectively for effect up to 24 h. In the chronic model of cotton pelletgranuloma viz; higher and lower doses of A, B and C exhibited 38.15%, 33.19% and 30.25 % and 19.45%, 18.55% and 17.55 % respectively. Conclusion: The studied models depicted that derivatives A, B and C have the probable potential as anti-inflammatory agents. Further studies need to undertaken to explore their potential in the different therapeutic areas.

: Alzheimer's disease (AD) is a chronic neurodegenerative brain disorder characterized by memory impairment, dementia, oxidative stress in elderly people. Currently, only a few drugs are available in the market with various adverse effects. So to develop new drugs with protective action against the disease, research is turning to the identification of plant products as a remedy. Natural compounds with anti-inflammatory activity could be good candidates for developing effective therapeutic strategies. Phytochemicals including Curcumin, Resveratrol, Quercetin, Huperzine-A, Rosmarinic acid, genistein, obovatol, and Oxyresvertarol were reported molecules for the treatment of AD. Several alkaloids such as galantamine, oridonin, glaucocalyxin B, tetrandrine, berberine, anatabine have been shown anti-inflammatory effects in AD models in vitro as well as in-vivo. In conclusion, natural products from plants represent interesting candidates for the treatment of AD. This review highlights the potential of specific compounds from natural products along with their synthetic derivatives to counteract AD in the CNS.

Purpose: The work was performed to investigate the feasibility of preparing ocular inserts loaded with Poly-ε-Caprolactone (PCL) nanoparticles as a sustained ocular delivery system. Methods: First, Atorvastatin Calcium-Poly-ε-Caprolactone (ATC-PCL) nanoparticles were prepared and characterized. Then, the optimized nanoparticles were loaded within inserts formulated with Methylcellulose (MC) and Polyvinyl Alcohol (PVA) by a solvent casting technique and evaluated physically, for in-vitro drug release profile. Finally, an in-vivo study was performed on the selected formulation to prove non-irritability and sustained ocular anti-inflammatory efficacy compared with free drug-loaded ocuserts. Results: The results revealed (ATC-PCL) nanoparticles prepared with 0.5% pluronic F127 were optimized with 181.72±3.6 nm particle size, 0.12±0.02 (PDI) analysis, -27.4± 0.69 mV zeta potential and 62.41%±4.7% entrapment efficiency. Nanoparticles loaded ocuserts manifested compatibility between drug and formulation polymers. Moreover, formulations complied with average weight 0.055±0.002 to 0.143±0.023 mg, and accepted pH. ATC-PCL nanoparticles loaded inserts prepared by 5% MC showed more sustained, prolonged in-vitro release over 24h. In-vivo study emphasized non-irritability, ocular anti-inflammatory effectiveness represented by smaller lid closure scores, and statistically significant lowering in PMN count after 3h. Conclusion: These findings proposed a possibly simple, new and affordable price technique to prepare promising (ATC-PCL) nanoparticles loaded inserts to achieve sustained release with prolonged antiinflammatory efficacy.
