Synthesis, characterization and biological activity of new mixed ligand complexes of Zn(II) naproxen with nitrogen based ligands.

A series of novel Zn(II) complexes [Zn2(nap)4] (1), [Zn(nap)21,10-phen](2), [Zn(nap)22,9-dmphen] (3), [Zn(nap)2(2-ampy)2] (4), [Zn(nap)2(imid)2] (5), [Zn(nap)2(1,2-dmimid)2] (6) (nap = naproxen, 1,10-phen = 1,10-phenanthroline, 2,9-dmphen = 2,9-dimethyl-1,10-phenanthroline, 2-ampy = 2-aminopyridine, imid = imidazole, 1,2-dmimid = 1,2-dimethyl imidazole) were synthesized and characterized using IR, UV-Vis, (1)H NMR, (13)C{(1)H} NMR spectroscopy. The crystal structure of complex 3 was determined using single-crystal X-ray diffraction. In order to assess the effect of the metal ions on the anti-bacterial activity, complexes 1-6 have been screened in vitro, against (G(+)) bacteria (Staphylococcus aureus and Micrococcus luteus) and (G(-)) bacteria (Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis and Escherichia coli) using the agar well diffusion method.

HPLC separation and antimalarial studies of plants from two different origins: Cameroon versus Luxembourg.

Background: Malaria is a devastating disease, particularly in Africa, due to development of resistance by against all known antimalarial drugs, including artemisinin. Therefore, the search for new antimalarial drugs is urgently needed, especially drugs that can impede the heme detoxification pathway in the malaria parasite, a crucial requirement for parasite survival in host erythrocytes.

Materials And Methods: Water infusions of plants from two different origins, Cameroon and Luxembourg, were used in this study.

New mixed ligand zinc(II) complexes based on the antiepileptic drug sodium valproate and bioactive nitrogen-donor ligands. Synthesis, structure and biological properties.

Starting from the precursor [Zinc Valproate complex] (1), new mixed ligand zinc(II) complexes of valproic acid and nitrogen-based ligands, formulating as, [Zn(valp)22,9-dmphen] (2), [Zn2(valp)4(quin)2] (3), [Zn(valp)2(2-ampy)2] (4), and [Zn(valp)2(2-ampic)2] (5) (valp = valproate, 2,9-dmphen = 2,9-dimethyl-1,10-phenanthroline, quin = quinoline, 2-ampy = 2-aminopyridine, 2-ampic = 2-amino-6-picoline) were synthesized and characterized using IR, (1)H NMR, (13)C{(1)H} NMR and UV-Vis spectrometry. The crystal structures of complexes 2, 3 and 4 were determined using single-crystal X-ray diffraction. The complexes were also evaluated for their anti-bacterial activity using in-vitro agar diffusion method against three Gram-positive (Micrococcus luteus, Staphylococcus aureus, and Bacillus subtilis) and three Gram-negative (Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis) species.

Clinical experience with biphasic insulin aspart in people with type 2 diabetes: Results from the Libya cohort of the A1chieve study.

Background: The A1chieve, a multicentric (28 countries), 24-week, non-interventional study evaluated the safety and effectiveness of insulin detemir, biphasic insulin aspart and insulin aspart in people with T2DM (n = 66,726) in routine clinical care across four continents.

Materials And Methods: Data was collected at baseline, at 12 weeks and at 24 weeks. This short communication presents the results for patients enrolled in biphasic insulin aspart sub group from Libya.
