Potassium Permanganate-Catalyzed Alpha-Pinene Oxidation: Formation of Coordination Compound with Zinc(II) and Copper(II), and Growth Inhibition Activity on <i>Staphylococcus aureus</i> and <i>Escherichia coli</i>

Abstract

ABSTRACT

Synthesis, Characterization and Antibacterial Properties of Nickel(II) Complex with 4-Aminoantipyrine Ligand

“…However, this was not the case for the complex, which has a smaller inhibition zone difference between both bacteria. Their antibacterial activity was found to increase with increasing concentration [4], but the complex exhibited a higher inhibitory activity than the metal and free ligand, as shown in the following order: nickel complex > nickel salt > AAP. Duncan Multiple Range Test (DMRT) was performed on the inhibitory diameters of all compounds against both bacteria at varying concentrations of 62.5; 125; 250; 500 and 1000 µg/mL.…”

“…The compound has several biologically active moieties in its structure, such as O, N, and methyl groups [1][2][3]. Aside from biological activities, antipyrine can form stable coordination bonds with central metal ions through carbonyl groups, such as the diketone complex containing transition metals, showing antibacterial activity [4]. Other transition metal complexes from antipyrine derivatives are also reported to be useful antimicrobial agents [4].…”

“…Aside from biological activities, antipyrine can form stable coordination bonds with central metal ions through carbonyl groups, such as the diketone complex containing transition metals, showing antibacterial activity [4]. Other transition metal complexes from antipyrine derivatives are also reported to be useful antimicrobial agents [4]. One antipyrine derivative, in particular, the 4aminoantipyrine (AAP) has gained significant attention from medicinal chemists due to the various pharmacological activities such as antimicrobial, antiinflammatory, analgesic, and antiviral [5][6][7][8].…”

Synthesis and Characterization of Polyaniline Nanoparticle by Inverse Micelle Microemulsion Method

“…Complement to these physical properties, the organic conductive polymer also gain attention for certain purposes, such as for solar cell [1], light emitting diode [2,3], conductive ink, sensor [4][5][6][7], semiconductor [8], super-capacitor [9], energy storage [10], catalysis and catalyst supporting material [11][12][13]. In our ongoing research finding non-metallic material catalyst for alpha-pinene oxidation [14][15][16] into more valuable chemicals, it turned up on polyaniline nanoparticle (PANI-NP) as prospectus catalyst. Polyaniline (PANI) consists of a long chain of benzenoid ring series and quinoid ring [17,18] and gives moderate conductivity [19][20][21] about 200 s/cm with hydrochloric acid as dopant [22].…”
