an efficient one-pot three-component procedure for the synthesis of new chiral spiro oxindolopyrrolidines/pyrrolizidines with highly regio- and diastereo-enantio, selective from 1,3-dipolar cycloaddition of azomethine ylides and chiral menthol-drived trans-cinnamic are described. the mechanism of the reaction is discussed on basis of the assignment of the absolute configuration of one of the cy...

activities of thirty bacterial strains obtained from plants rhizosphere in different areas against phytophthora drechsleri were assessed through in vitro and greenhouse experiments. dual culture and extracellular metabolites tests were used in in vitro assays. the bacterial strains inhibited growth of p. drechsleri, the highest inhibition zones was belonged to t17-4 strain with 61.904% in dual ...

a variety of group 4 metal catalytic systems (c2-symmetric {ebthi}-, {sbi}-type zirconocene complexes (c2-1–4); c1-symmetric (c1-5–8) and cs-symmetric (cs-9) {cp/flu}-type zirconocene complexes; cp*2zrcl2 (cp* 2-10)), half-metallocene complexes (cpticl3, hm-11), constrained-geometry (cgc-12) titanium catalysts) and post-metallocene catalysts (dow’s ortho-metallated amido-pyridino hafnium comple...

inflammation can lead to malabsorption of important micronutrients such as iron. malabsorption and nutritional deficiency can be caused by a variety of pathological and environmental factors causing a range of other symptoms commonly caused by both h. pylori infection and coeliac disease (cd). national guidelines suggest the routine taking of duodenal biopsies to exclude cd when investigating p...

cr(iii), co(ii), ni(ii), cu(ii) and zn(ii) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their  in-vitro antimicrobial activity against three bacterial strains, mycobacterium smegmatis (gram +ve), escherichia coli (gram -ve), pseudomonas aeuroginosa (gram -ve) and three fungal strains, nigrospora oryzae, ...

alnus glutinosa, fraxinus excelsior and papaver rhoeas have long been used in folkloric medicine for the treatment of various ailments. as part of our continuing screening of plant extracts for activities, the extracts of a. glutinosa, f. excelsior and p. rhoeas have been screened for their antioxidant and antibacterial activities, as well as their general toxicity towards brine shrimps. among ...
