Synthesis, Characterization and Study of Antibacterial Activity of Methacrylic Copolymer

Abstract

4-Benzyloxyphenylmethacrylic copolymers with Glycidyl methacrylate were synthesized from the monomer, 4-Benzyloxyphenylmethacrylate (4-BOPMA) by free radical solution polymerization. The synthesized monomer and co-polymer were characterized by UV, FT-IR, H 1 -NMR and C 13 -NMR spectroscopic techniques. The thermal stability of the polymers was determined by TGA in inert atmosphere. The glass transition temperatures of the polymers were determined by DSC analysis. The antibacterial activities of the polymers were also studied by UV spectroscopy at various concentration. The results of the TGA analysis showed that the polymers had good stability upto 250 C. Compared to homopolymer, the copolymer shows a broad spectrum of antibacterial properties.

Pentacyclic triterpene derivatives possessing polyhydroxyl ring A inhibit Gram-positive bacteria growth by regulating metabolism and virulence genes expression

“…The antibacterial activity of all derivatives was evaluated preliminarily using a single-dose of 100 µM by turbidimetry assays, ampicillin and streptomycin were used as positive controls [22]. against Gram-negative bacteria E. coli and R. solanacearum.…”

“…This study a number of new derivatives possessing polyhydroxyl ring A were semisynthesized from the natural products UA or OA, and their antibacterial activity was evaluated in vitro. Some new derivatives (16,18,22,23,24) displayed strong growth inhibitory activity against Gram-positive bacteria. The assessed antibacterial mechanism revealed the effect of the derivatives on regulation of genes involved in metabolism and virulence.…”

Methacrylate Polymers Having Pendant Chalcone Moieties: Monomer Reactivity Ratios, Thermal and Optical Properties

“…A substantial fraction of the methacrylate products are copolymers. [18][19][20][21] Polystyrene (PSt) is one of the world's most widely used polymers. The copolymers of styrene with methacrylates are very important to industry applications such as paints, adhesives, and coatings.…”
