    Opis:
    Three Schiff bases derived from thiosemicarbazide and ketones (Vanillin, Benzophenone and Acetophenone) were used to study their antibacterial activities against some pathogenic bacteria by disc diffusion method. Of these, benzophenone thiosemicarbazone showed significant antibacterial activity as compared with that of Kanamycin. All these three compounds were found to possess cytotoxic effect. Minimum inhibitory concentration of these compounds was also determined.

    Opis:
    N-chloropyrazinamide was prepared by the chlorination of pyrazinamide using trichloroisocyanuric acid. The experimental results ascertained that the tested N-chloropyrazinamide showed good antimicrobial activities when compared to standard drug. It was found that N-chloropyrazinamide at different concentrations exhibited significant dose dependent anti-oxidant, anti-inflammatory and anti-hypertensive activity.

    Opis:
    A new series of four transition metal complexes of a Schiff base derived from salicylaldehyde and glycine, viz. [N-salicylidene glycinato diaqua cobalt (II) dimer] (SGCo)2, [N- salicylideneglycinato-di-aqua-nickel(ll)dimer] (SGN)2, [N-salicylideneglycinato-aqua-copper(II)] (SGC) and [N-salicylidene glycinato diaqua zinc(II) dimer] (SGZ)2 have been synthesized and characterized through a rapid, simple, and efficient methodology in excellent yield. These compounds were screened for in vitro antibacterial activities against six pathogenic bacteria, such as Shigella sonnei, Escherichia coli, Bacilus subtilis, Sarcina lutea, Staphylococcus aureus and Pseudomonas arioginosa. The antibacterial activity was determined by the disc diffusion method using DMSO as solvent. The results indicate that (SGC) compound exhibit a significant antibacterial activity, depending on the bacterial strain and (SGCo)2, (SGN)2 and (SGZ)2 compounds show a moderate sensitivity even with higher doses. All these compounds were found to possess cytotoxic effect.

    Opis:
    A series containing twelve titled compounds were synthesized by solvent-free method and their purities were examined by literature procedure. These compounds were subjected to study the pharmacological effects such as antibacterial, antifungal and antioxidant activities and the insect antifeedant activities using Bauer-Kirby disc diffusion method with their bacterial and fungal strains, DPPH radical scavenging and leaf disc bio-assay method with 4th instar larvae Achoea janata L.

    Opis:
    Some new dihydropyrano[c]chromenes derivatives are synthesized from 4-hydroxycoumarin. The structure of newly synthesized compounds was confirmed by mass, 1H NMR and IR spectroscopy. Further, antimicrobial screening of these synthesized compounds was done against some bacterial (Gram positive as well as Gram negative) and fungal strains in N,N-dimethylformamide. It is observed that some of synthesized compounds exhibited significant antibacterial activity against Gram positive bacterial strains. The selected fungal strains were most resistant for the studied compounds as none of the synthesized compounds showed activity against any of the fungal strain studied. The best antibacterial activity was shown by ABR-10.

    Opis:
    In this newly approached method a novel series of Transition metal complexes were synthesized by the reaction of 5-bromo-2-fluorobenzaldehyde (1) react with hydroxylamine in ethanolic solution at room temperature. Mononuclear complexes were synthesized by reaction with Cu(II) , Zn(II) and Hg(II) chloride salts. The complexes were characterized by elemental analysis, Ultraviolet, Infra -red and 1HNMR spectral studies. The antimicrobial activities of the ligand and its metal complexes were estimated.
