“…Antimicrobial activities of sulphadrugs and metal complexes may be enhanced by the presence of oxygen, nitrogen, and sulfur atoms which have chelating properties . Antibacterial and antifungal activities of monomer and metal polymer complexes were tested against three local Gram positive bacteria ( Bacillus cereus , Staphylococcus aureus and Enterococcus faecalis ), three local Gram negative bacteria ( Escherichia coli , Klebsiella pneumoniae and Pseudomonas aeruginosa ) and three local fungi ( Aspergillus niger , Fusarium oxysporum and the yeast Candida albicans ) and the results were recorded in Tables and .…”

Monomer of N‐[4‐(5‐methyl‐isoxazol‐3‐ylsulfamoyl)‐phenyl]‐acrylamide (HL) and some transition metal polymeric complexes of the general formula {[M(HL)(OH2)2(OCOCH3)2] xH2O}n (M = Co(II), x = 2; Ni(II), x = 3; Mn(II), x = 2) and [Cd(HL)2(OCOCH3)2] were synthesized and characterized by elemental analysis, IR, UV spectroscopy, conductance measurements, magnetic susceptibility, thermogravimetric analyses and X‐ray diffraction analysis. In all polymer complexes, the spectral data revealed that the ligand act as bidentate neutral molecule and coordinate to metal ion through enolic sulphonamide OH and isoxazol‐N. In all polymer complexes, the spectral data revealed that the ligand act as bidentate neutral molecule and coordinate to metal ion through enolic sulphonamide OH and isoxazol‐N. The molar conductance data revealed that the polymer complexes are non‐electrolytes while UV‐vis and magnetic measurements data have been shown that the polymer complexes have octahedral geometry. All the studies revealed coordination six for the metals in all the polymer complexes and octahedral structures were suggested. The inhibitive effect of HL against C38 steel was investigated in 2 M HCl solution (tafel polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) methods). The type of HL is mixed inhibitor whose adsorption habit onto C38 steel.

“…Metal complexes of polymers synthesized by the OP have useful properties such as paramagnetism, metal ion uptake, antimicrobial activity and antistatic agent [17][18][19]. The complex forming polymeric ligands are characterized by reactive functional groups containing O, N and S donor atoms and capable of coordinating to different heavy metal ions that have been usually studied [20].…”

“…Generally, phenolic groups of CUR are modified to enhance the solubility. 23 Similarly, monomer derivative N-[4-sulfamido-N-(5-methyl-3-isoxazolyl)-phenyl]maleimide was polymerized by free radical polymerization. 13 Encapsulation of CUR in various polymeric materials for drug delivery applications have been reported.…”

“…However, studies on CUR or modified CUR entrapped in a polymer matrix used for wound dressing materials showed an initial burst in activity with sustained release. 23 Two novel organotin monomers, (N-tri-n-butyltin)maleimide (N-TBTM) and m-acryloylamino-(tri-n-butyltinbenzoate) (m-AATBTB), were copolymerized with styrene in bulk at 65 1C using azobisisobutyronitrile as the free radical initiator to attain the respective antibacterial polymers. [14][15][16][17][18] Various biocompatible polymers are being designed and fabricated in the form of gels, films and nanofibers with and without drugs to promote wound healing by regeneration of tissues.…”

Two new (meth)acrylate monomers, namely, 4-((1E,6E)-7-(4 0 -hydroxy-3-methoxyphenyl)-3,5-dioxohepta-1,6dienyl)-2-methoxyphenyl acrylate or curcumin monoacrylate (CmA) and 4-((1E,6E)-7-(4 0 -hydroxy-3methoxyphenyl)-3,5-dioxohepta-1,6-dienyl)-2-methoxyphenyl methacrylate or curcumin monomethacrylate (CmMA), are synthesized by reacting (1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione (curcumin) with acryloyl chloride and methacryloyl chloride, respectively. The respective derivatives are polymerized by free radical polymerization using an initiator, 2,2-azobisisobutyrontrile (AIBN), to obtain the oligomer of curcumin monoacrylate (OCM) and the oligomer of curcumin monomethacrylate (OCMA). The oligomers are characterized by FTIR, 1 H NMR and UV-vis spectroscopy. The molecular weights of the oligomers are determined by GPC to range between 2000 and 5500 Da. The melting temperature (T m ) and degradation temperature of the respective oligomers are evaluated by thermal analysis. The melting temperature of the oligomers ranged from 195 to 197 1C. Antibacterial studies are evaluated against Staphylococcus aureus, in which the minimum inhibitory concentration (MIC) of OCA1 is 27 mg mL À1 . The blends of the individual oligomers with poly(lactic acid) are electrospun to obtain the respective non-woven nanofiber mats. Nanofibers are formed, with the diameter ranging from 400 to 750 nm, and the nanofiber mats are porous. Because the nanofiber mats are antibacterial and highly porous, they may have potential application as a wound dressing material for tissue regeneration.
