Synthesis of a new series of [5-(1H-indol-3-yl)-3-phenyl-4, 5-dihydropyrazol-1-yl]pyridin-3-yl methanone derivatives (3a-3g) by the reaction of nicotinic acid hydrazide with various indolyl chalcones (2a-2g) has been described. The indolyl chalcones have been synthesized from indole-3-carboxaldehyde and different substituted acetophenones. The structures of(More)
Cyanobacteria play a vital role in the production of phycobiliproteins that includes phycocyanin and phycoerythrin pigments. Phycocyanin and related phycobiliproteins have wide variety of application that is used in the food, biotechnology and cosmetic industry because of their color, fluorescent and antioxidant properties. The present study is focused to(More)
Pure ZnO and Neodymium (Nd) doped ZnO nanoparticles (NPs) were synthesized by the co-precipitation method. The synthesized nanoparticles retained the wurtzite hexagonal structure. From FESEM studies, ZnO and Nd doped ZnO NPs showed nanorod and nanoflower like morphology respectively. The FT-IR spectra confirmed the Zn-O stretching bands at 422 and 451(More)
Extended spectrum beta lactamase (ESBL) are emerging beta-lactamases in Gram-negative pathogens, causing serious problems in hospitalized patients worldwide. Biofilm mode of virulence has decreased the efficiency of antibiotics used for treatment against ESBL pathogens. Therefore, there is an urgent need for alternative agents such as nanoparticles that can(More)
Nitrate is the predominant form of inorganic nitrogen utilized by higher plants, fungi and algae and its assimilation forms the major pathway for production of biologically useful nitrogen. Chlorella is a unicellular eukaryotic green alga, which offers a potentially useful system for the expression of hetrologous proteins. In the present study the(More)
