2018-09-06 07:47:58 الكلمات المفتاحية NMR, VO(II), imines, Chelates, thermal analyses, Antimicrobial activity, DNA interaction, Anticancer, IR, TGA, Docking, Cr(III),
DNA interaction, antimicrobial, anticancer activities and molecular docking study of some new VO(II), Cr(III), Mn(II) and Ni(II) mononuclear chelates encompassing quaridentate imine ligand
The present study was conducted to synthesis of some new imine Cr(III), VO(II), Mn(II) and Ni(II) complexes derived from the condensation of 2-amino phenol with 2-hydroxynapthaldehyde were synthesized. The prepared HNPN imine ligand was analyzed by its melting point, IR, 1H NMR and 13C NMR spectroscopies. The investigated HNPN imine complexes were characterized by elemental analysis, FT IR, UV–vis and ... إقراء المزيد

Toxicological and Biological Activities of the Acid Secretion of Berthellina citrina (Heterobranchia, Pleurobranchidae) from the Red Sea
_Berthellina citrina _is a pleurobranchid opisthobranch characterized by its skin acid-secretion that contains sulphate and chloride ions with traces of organic matter. To identify defensive potential and bioactivity, we tested this secretion for the first time against _Artemia salina_, different strains of microorganisms, human RBCs and human cancer cell lines. It showed lethality to _A. salina _with LC50 values 83.86 ... إقراء المزيد

Synthesis and Antimicrobial Activity of Substituted Nitrotetrazole-5-Carbaldehyde Hydrazones
A series of substituted -nitrotetrazole-5-carbaldehyde hydrazones were synthesized and tested for antimicrobial activity with respect to _Staphylococcus aureus_, _Streptococcus pneumoniae_, _E. coli_, _P. aeruginosa_, and _Micrococcus_. The minimum inhibitory concentrations were determined. إقراء المزيد
