Room temperature ionic liquids (RTILs), a class of green and neoteric solvents, have attracted increasing interest over recent years as environmentally benign excellent alternatives to organic solvents in homogeneous and biphasic processes synthesis of several nanoparticles. A novel magnetically recoverable ionic liquid (1,1–Bis(3-Methylimidazolium-1-yl)methanechloride)-stabilized ferrous sulfide (FeS NPs) was fabricated by almost all the known a simple reduction method. Firm ferrous sulfide nanoparticles were prepared in good capitulate by reduction of ferric chloride using sodium borohydride by different reagents like thioacetamide (TAA) and sodium thiosulfate in the presence of ionic liquid such as 1,1-Bis(3-Methylimidazolium-1-yl) methane chloride. In the present investigation, FeS nanoparticles through different starting materials were synthesized and its characteristics were compared with each other. Structures were confirmed by elemental and spectral studies such as FT-IR spectroscopy, X-Ray Diffraction (XRD) analysis, Scanning Electron Microscope (SEM) analysis, Energy Dispersive X-ray spectroscopy (EDX), and Transmission Electron Microscopy (TEM)...

In the present study, Justicia adhatoda was used for synthesizing AgNPs and characterized using UV-visible, FTIR, XRD, and SEM analysis and checked for its teratogenic effect and bactericidal activity. UV–Vis spectra analysis revealed that the synthesized AgNPs had a peak around 434 nm, while XRD and SEM analysis showed that AgNPs have spherical shapes with sizes ranging from 22 to 29 nm. Fourier transmission infrared (FTIR) analysis authorized the presence of bio interactive hydroxyl, amide, and carbonyl groups playing an important reduction role in the process of nano-synthesis. The acute developmental toxicity of Justicia adhatoda leaf extracts with nanosynthesised AgNPs on the embryos of the zebrafish, Danio rerio, revealed that the mortality, hatchability, heartbeat rate, teratogenicity, and embryogenicity were all concentration-dependent. The lethal effects were prominent in biosynthesized AgNPs, whereas sub-lethal and teratogenic effects like lordosis, scoliosis, pericardial edema, yolk sac edema, head malformation, tail malformation, and growth retardation were expressed in 79% of the embryos. Pericardial edema and Tail malformation were the most prevalent in higher concentrations signifying...

The main purpose of the current research work is to enhance solubility and dissolution of BCS Class II drug, Flurbiprofen using liquid-solid compact technology. Flurbiprofen is a non-steroidal anti-inflammatory drug indicated for acute and chronic treatment of rheumatoid arthritis, osteoarthritis, and spondylytis. The rationale to select Flurbiprofen as the model drug is that it belongs to BCS Class II, having poor aqueous solubility of 10.45 ± 3.2μg/ml. Hence an attempt was made to enhance solubility, which may further increase the dissolution profile of the drug. In this regard, several liquisolid compact formulations were prepared for flurbiprofen and subjected to evaluation. They were prepared by using PEG 600 as a non-volatile solvent to dissolve the drug and further converted to freely flowing readily compressible powder using Avicel PH 102 as carrier material and Aerosil 200 as coating material. These liquisolid formulations were subjected to pre-compression rheological studies and post-compression evaluation parameters such as hardness, friability, weight variation, content uniformity, disintegration, and in-vitro dissolution. Results of dissolution profile of formulation TF3...

Forced degradation studies are a vital tool in pharmaceutical research and development to predict long-term stability. Stress studies should be performed in method development to know drug behavior but can also be performed with method validation for regulatory filling predict stability, and measure impurities. It is especially valuable when little data is free about potential degradation products. Forced degradation studies may help encourage drug advancement in regions like formulation development, manufacturing, and packaging, in which information on substance conduct can be utilized to improve a medication item. Hence it is important to realize the purity profile and conduct of a medication substance under various natural conditions. For stable formulation development, comprehension of synthetic conduct forced degradation pathways and degradants of drug substance and drug product is very important. Therefore, by using different regulatory guidelines in the present review paper, we described the broad overview of forced degradation studies by determining the system to perform stress studies & its methods for isolation and identification of...

To investigate the phytoconstituents and anticancer potential followed by apoptotic studies of H. undatus fruit extracts on HepG-2 cells. Qualitative phytochemical profiling and anti-proliferation activity of Aqueous, Chloroform, Ethyl acetate, Hexane, and Methanol extracts of dragon fruit pulp was carried out. Based on the results of anti-proliferation studies, methanol extract was taken further for apoptotic study by treating HepG-2 cells for nuclear staining using DAPI and GC-MS analysis to elucidate the presence of active compounds. Qualitative phytochemical analysis revealed the presence of carbohydrates, tannins, saponins, anthocyanin, quinones, cardiac glycosides, terpenoids, triterpenoids, phenols, acids, and steroids in aqueous fruit extract. Similarly, chloroform fruit extract showed the presence of carbohydrates, saponins, alkaloids, cardiac glycosides, triterpenoids, phenols, and coumarins. Likewise, Ethyl acetate fruit extract had carbohydrates, tannins, saponins, flavonoids, alkaloids, anthocyanin, cardiac glycosides, terpenoids, triterpenoids, acids, and steroids. In hexane fruit extract, carbohydrate, saponins, anthocyanin, quinones, phenols, and acids were present. But more phytocompouds such as carbohydrates, tannins, saponins, flavonoids, alkaloids, anthocyanin, cardiac glycosides, terpenoids, triterpenoids, phenols, acids, and steroids were found...
