12 membered Schiff base macrocyclic ligands, 6,7,14,15-tetra phenyl-1,2,3,4, 4a,8a, 9,10, 11,12, 12a,16a-dodecahydro dibenzo [b,h] [1,4,7,10] tetraazacyclododecine L1, and 14 membered Schiff base macrocyclic ligands, 6,8,15,17-tetramethyl-1,2,3,4, 4a,7,9a, 10,11,12,13,13a,16,18a-tetra decahydro dibenzo[b,i] [1, 4,8,11] cyclotetradecine tetraaza L2, 7,16-bis(2,4- dichloro benz ylidene)-6,8,15,17-tetra methyl-1,2,3,4, 4a,7,9a, 10, 11,12, 13, 13a,16,18a-tetra deca hydro dibenzo [b,i] [1,4,8,11] tetra azacyclo tetra decine L3 and 6,8,15, 17-tetramethyl-1,2,3, 4,4a,9a,10, 11,12,13,13a,18a-dodecahydro dibenzo [b,i] [1,4,8, 11] tetraazacyclo tetradecine (7,16-diylidene) bis(methanylyli dene) bis (N,N-dimethylaniline) L4 were synthesized by condensation reaction between diketone and aliphatic diamines. The metal complexes of the types, [ML1Cl2], [ML2Cl2], [ML3Cl2] and [ML4Cl2] [M= Co(II), Ni(II), Cu(II), Mn(II), Hg(II), and Fe(II)] were prepared by interaction of ligands, L1, L2, L3 and L4 with metal(II) ions. The ligands and their complexes were characterized by elemental analysis, magnetic susceptibility, conductivity measurements and IR, 1H and 13C NMR, UV–Vis spectral studies. The thermal stability of the complexes was also studied by TGA analyses. These studies show that all the complexes have octahedral arrangement around the metal ions. We used CB-Dock, a novel blind docking technique that aims to improve docking precision. With the aid of the cutting-edge docking program Autodock Vina, software online, molecular docking studies were used to evaluate the biological significance of the synthesized ligands and identify the probable and efficient binding mechanisms between the various ligands and the active site of the receptor protein. Affinity binding of both Ligand L3 and L4 to Penicillin binding protein 2x (chain B) with PDB 1PYY were much better than to Penicillin binding protein 2B (chain A) with PDB 1WAE due to the presence of hydrogen and halogen bonds. Therefore, they can be more recommended for drug design study to inhibit bacterial growth due their bioavailability. The biological activities of all compounds were evaluated like in-vitro antioxidant activity or percentage free radical scavenging effect via DPPH method against standard ascorbic acid and in vitro anticancer activity via MTT assay against colon cancer cell lines. Results of the biological activities showed that complex CuL3Cl2 exhibited the highest anti-cancer activity against colon cancer cell line i.e. 70.72±6.3 μg/ml among other copper complexes whereas compound CuL3Cl2 showed best antioxidant activity against ascorbic acid i.e. 75.07±1.96 μg/ml. While the biological activities showed that complex CuL4Cl2 exhibited the highest anti-cancer activity against colon cancer cell line i.e. 42.05±7.4 μg/ml among other copper complexes whereas compound CuL4Cl2 showed best antioxidant activity against ascorbic acid i.e. 65.47±1.37 μg/ml.

Synthesis and Characterization of 3-(4-Antipyrene azo)-4-amino benzoic acid Complexes with Selected Metal Ions
...Show More Authors

Coupling reaction of 4-amino antipyrene with 4-amino benzoic acid gave bidentate azo ligand. The prepared ligand was identified by Microelemental Analysis, 1HNMR, FT-IR and UV-Vis spectroscopic techniques. Treatment of the prepared ligand with the following metal ions (CoII, NiII, CuII and ZnII) in aqueous ethanol with a 1:2 M:L ratio and at optimum pH, yielded a series of neutral complexes of the general formula [M(L)2]Cl2 . The prepared complexes were characterized using flame atomic absorption, (C.H.N) Analysis, FT-IR and UV-Vis spectroscopic methods as well as magnetic susceptibility and conductivity measurements. Chloride ion content was also evaluated by (Mohr method). The nature of the complexes formed were studied following the mol

Design and Synthesis of New Non-Steroidal Anti-inflammatory Agents with Expected Selectivity toward Cyclooxygenase-2 Inhibition
...Show More Authors

This study includes design and synthesis of new non-steroidal anti-inflammatory agents (NSAIDs) with expected cyclooxygenase-2 (COX-2) selective inhibition to achieve better activity and low gastric side effects. Two series of compounds have been designed and synthesized as potential NSAIDs,these  are:     Salicylamide derivatives (compounds 3,4,5 ) and Diflunisal derivatives (compounds 10&11). In vivo acute anti-inflammatory effect of one of the synthesized agents (compound 3)  was evaluated in the rat using egg-white induced paw edema model of inflammation. Preliminary pharmacological study revealed that compound 3 exhibited less anti-inflammatory effect  compared to that of aspirin after

Synthesis, Characterization, and Anti-microbial Study of Polycyclicacetal Metal Complexes Derived from PEG and (Erythro-Ascorbic Acid) Derivative
...Show More Authors

Polymer metal complexes of poly ethylene glycol acetal and Ag (I), Cu (II), Ni (II), Mn (II), Co (III) and Hg (II) were prepared from the reaction of PEG with aldehyde derived from Erythro-ascorbic acid (pentulosono-ɣ-lactone-2, 3- enedianisoate). All these compounds were characterized by Thin Layer Chromatography (TLC) and FTIR spectra and aldehyde was also characterized by (U.V-Vis), 1HNMR,13CNMR, and mass spectra. It has been established that, the polymer and its metal complexes showed good activities against four pathogenic bacteria (Escherichia coli ,Klebsiellapneumonae, Staphylococcusaureus, Staphylococcus Albus) and two fungal (Aspergillus Niger,Yeast). The polymer metal complexes showed higher activity than the free polymer. The

Synthesis of New Pyrazoline - Phenoxathiin Derivatives
...Show More Authors

Phenoxathiin was prepared by the reaction of diphenyl ether with sulfur in the presence of anhydrous aluminum chloride. This work comprised the synthesis of new phenoxathiin derivatives containing heterocyclic moieties. These heterocyclic compounds were synthesized in three groups. The first group was made up of 2-(oxoalken-1-yl) phenoxathiin derivatives (3a-3j) obtained from the reaction of 2-acetylphenoxathiin with different aromatic aldehyde in the presence of sodium hydroxide. The other two groups involved compounds produced from the reaction of (3a-3j) with hydrazine hydrate in acetic acid to get 2-(1-acetyl pyrazolin-3-yl) phenoxathiin derivatives (4a-4j), and phenyl hydrazine in the presence of piperidine to afford 2-(1-phenyl pyrazo
