    Abstract: Objectives: The aim of this study is to synthesize silver nanoparticles using the algal extract of Padina tetrastromatica and evaluate its antifungal activity against pathogenic fungus isolated from clinical samples.Results: Formation of brown color at 15 minutes indicates the production of silver nanoparticles by the extract of brown algae P. tetrastromatica. Surface plasmon resonance band was centered at 440 nm which was observed by UV-vis spectrophotometer. SEM image revealed spherical and cubical nanoparticles with high agglomeration, and energy-dispersive X-ray illustrates elemental components of silver formed at 3 keV. TEM shows spherical, truncated, and ellipsoidal nanoparticles and also it evidences the algae compounds that are capped with nanoparticles. SAED pattern proved four diffraction face-centered cubic rings at (111), (200), (220), and (311) which indicates the crystalline nature of nanoparticles. Silver nanoparticles show high inhibition activity against Fusarium sp, Aspergillus niger, Candida albicans, Aspergillus fumigatus, and Aspergillus flavus at different concentrations. P. tetrastromatica-mediated synthesis of silver nanoparticles shows rapid and eco-friendly silver ion reduction process.Methods: Dried algal biomass was used to prepare the pure algal extract and added with 1 mM AgNO , and the color change was noted and recorded by ultraviolet (UV)-vis spectrophotometer. The morphological characteristics were analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Crystalline structure was analyzed by SAED pattern. Antifungal activity was performed by agar well diffusion method against various pathogenic fungi.Conclusion: Therefore, this present study elucidates that algae-mediated synthesized silver nanoparticles have antifungal activity against pathogenic fungi, so it can be developed as a novel medicine for human welfare in biomedical applications in the near future.Keywords: Padina tetrastromatica, Silver nanoparticles, Transmission electron microscopy, Antifungal activity, Green synthesis.

    Abstract: ABSTRACTObjective: The objective of this study is to investigate a simple and feasible approach for the production of silver nanoparticles (AgNPs) by using leafextract of Ipmoea nil and to evaluate its antibacterial activity.Methods: The AgNPs synthesized was characterized by a change in color and the absorption peaks by ultraviolet-visible spectroscopy. The phytocompounds responsible for the reduction and capping of silver ions was known from Fourier transform infrared spectra and phytochemical analysis.The antibacterial effects of prepared aqueous AgNPs were detected against five types of pathogenic bacteria, including Gram-negative and Grampositivebacteria (Escherichia coli, Salmonella, Bacillius, Proteus, and Klebsilla pneumonia) using agar well diffusion method.Results: A peak absorption value between 400 and 450 nm and the color change of the extract from yellowish to red wine were corresponds tothe plasmon absorbance of AgNPs. On the other hand, aqueous extract of I. nil mediated AgNPs found to be effective against tested microorganisms(Salmonella, Bacillus, and Proteus) with inhibition zone in the range of 10-13 mm (20 μl and 10 μl) except E. coli and K. pneumonia. Furthermore,aqueous extract of I. nil leaves had no ability to suppress the growth of the tested microorganisms in the concentration of 10 μl. The control alsoproduced similar inhibition zones like AgNPs.Conclusions: Our findings indicated that green synthesized AgNPs mediated by I. nil leaf extract had an efficient anti-bactericidal activity against thebacterial species tested. Hence, further studies are needed to highlight its mechanism and application as an antibacterial agent.Keywords: Ipomoea nil, Silver nanoparticles, Antibacterial activity, Bacteria.

    Abstract: Objective: Synedrella nodiflora is traditionally used in the treatment of several ailments. Pharmacologically, this plant has anticonvulsant, sedative, anti-nociceptive and anti-proliferative effects. This study further investigated S. nodiflora for its antioxidant and in vitro inhibition of cancerous cell lines. Methods: Phytochemical assays, and the DPPH radical scavenging method were employed in preliminary screening for antioxidant activities of the crude hydro-ethanolic extract (SNE) and resulting fractions. The potent ethyl acetate fraction (EAF), was further investigated for total phenol and flavonoid contents, reducing power, lipid peroxidation potential, and cytotoxic effects on human breast cancer (MCF-7), leukemic (Jurkat), and normal liver (Chang’s liver) cell lines. Results: The extract contained phenols, flavonoids, tannins, glycosides, sterols, terpenoids, and alkaloids. It scavenged for DPPH with an IC50 of 114 µg/ml, whereas that of EAF was 8.9 µg/ml. EAF prevented peroxidation of egg lecithin at an IC50 of 24.01±0.08 µg/ml. These IC50s are four and three times lower than the reference standards. EAF produced anti-proliferative effects against MCF-7, and Jurkat cell lines with IC50s of 205.2 and 170.9 µg/ml, respectively. EAF had a high IC50 of 252.2 µg/ml against Chang’s liver cells. At 0.1 mg/ml EAF had similar total flavonoid content to SNE, but a significantly higher total phenol content. Conclusion: The ethyl acetate fraction of S. nodiflora, exhibited the most potent antioxidant activity. It inhibited the proliferation of breast and leukemic cancer cell lines, whiles having weak cytotoxic effect on normal liver cells. These can be explored for further drug development.

    Abstract: Objective: The main aim of the present investigation was to develop sustained release microbeads of ritonavir that has a shorter half-life (3-5 h) and requires twice a day administration. These formulations exhibit a sustained release of ritonavir that would expect to improve the therapy, better drug utilization, and patient compliance. Methods: Gellan-chitosan and calcium chloride reinforced beads of ritonavir were prepared by ionotropic gelation method employing different concentrations of gellan, chitosan, calcium chloride and drug. The prepared beads were evaluated for various physicochemical parameters such as particle size determination, drug entrapment efficiency, swelling studies, infrared spectroscopy study, differential scanning calorimetry, x-ray diffraction analysis, scanning electron microscopy, in vitro drug release study and in vivo bioavailability studies. Results: From the results, formulation GC-II exhibited higher drug entrapment efficiency (79.65±0.012), higher swelling index, sustained drug release over a period of 24 h, increased oral bioavailability (2.07 times higher than that of pure drug) and decreased elimination rate (2.15 times lesser for ritonavir microbeads) with prolonged elimination half-life (2.15 times more than pure drug) as compared to pure drug. Conclusion: Ritonavir microbeads have demonstrated as a better delivery system for the sustained release of the drug; which may in turn circumvent the drawbacks associated with the conventional therapy.
