The present study deals with the synthesis and characterization of nanocrystalline vanadium pentoxide (V2O5) nanoparticles and their antibacterial and antifungal activity onStaphylococcus aureus and Aspergillus niger, respectively, by agar diffusion method. The metal oxide has been synthesized by employing the sol-gel method, polyaniline (PANI) has been synthesized by chemical oxidation, and PANI/V2O5composites have been synthesized byin situpolymerization method with different ratios (10, 20, 30, 40, and 50 weight%) of V2O5in PANI. The newly prepared composites were characterized by FTIR and powder X-ray diffraction (P-XRD) techniques and are found to be formed of PANI/V2O5nanocomposites, and also the compounds showed moderate antibacterial and antifungal activity.

Antibacterial And Antifungal

Four new Schiff bases were synthesized from condensation of aldehyde ( 2-hydroxy benzaldehyde ) with aromatic amines (4-introaniline ; 4,4-oxydianiline ; 4,4-diaminodipleny sulfone and sulfanilamide) . These Schiff bases were characterized by IR, NMR , GC. mass and element analysis. Moreover, the Schiff bases were screened for their antibacterial and antifungal activity against various microorganisms and compared with standard compounds. In general , the results were indicated that some Schiff bases had good antimicrobial activity.

Antimicrobial And Antifungal Activities

Three series of some novel chalcone based urea, thiourea and acetamide derivatives were designed, synthesized and screened for their antimicrobial and antifungal activities. All the synthesized compounds are first reported. The structures of the compounds were elucidated with the aid of elemental analysis and spectral methods including IR, 1H-NMR spectral data. The prepared compounds were evaluated for antibacterial activity against two Gram-positive bacteria (Staphylococcus aureus, Staphylococcus pyogenus), two Gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli). The title compounds were also investigated for their antifungal activity using the broth micro dilution method. The bioassay results showed that compounds a few compounds showed good to superior in vitro antibacterial and antifungal activity.

A series of novel 1,3,5-trisubstituted pyrazoline derivatives (P1-P10) have been synthesized by the reaction of substituted chalcones (C1-C10) with 4-hydroxybenzhydrazide. The starting material, chalcones were prepared by claisen Schmidt condensation of 4-methylacetophenone with substituted aldehydes in the presence of sodium hydroxide in ethanol. 4-hydroxybenzhydrazide was synthesized by condensing methyl 4-hydroxybenzoate with hydrazine hydrate. The cycloaddition of chalcones with 4-hydroxybenzhydrazide gives 1, 3, 5-trisubstituted pyrazoline derivatives. The structures of synthesized derivatives were confirmed by IR, 1HNMR and 13C NMR spectrum. The synthesized compounds were screened for their antibacterial and antifungal activity.

The synthesis and characterization of first row transition metal complexes of the 1, 4(2'-hydroxyphenyl-1-yl) di-imino azine {1,4(2'HPDA)} are reported. The complexes have been characterized by elemental analysis, molar conductance, magnetic studies, IR, 1H NMR and UV-visible studies. They have the stoichiometry of the type [M{1,4(2'HPDA)}22H2O ] and [M'L2] where M= Mn(II), Fe(III), Co(II), Ni(II) and Cu(II), and M' = ZrO(II), VO(II), Zn(II), Cd(II), and Hg(II). The antibacterial and antifungal activity of the metal complexes has been investigated. Both ligand and complexes have shown good antibacterial and antifungal activity.
