A variety of organic copolymers have been synthesized from phenolic compounds like p-Hydroxybenzoic acid, p-Hydroxybenzaldehyde, p-Hydroxyacetophenone, and also from nitrogen- containing compound like anthranilic acid, aniline, urea, biurate. These copolymers have been studied for various properties like thermal behavior, kinetic parameters, antimicrobial screening, ion-exchange study, polymer composites, photoluminiscence etc. Kinetic parameters of the copolymers derived from phenolic and nitrogen-containing compounds have been studied using Freeman-Carroll (FC) and Sharp-Wentworth (SW). Based on TGA, thermal stability and decomposition temperature have been studied for the copolymers and composites. Higher thermal stability for copolymer composites has been found as compared to the copolymer because the composite has a high activation energy and more residue left out at the end of the decomposition process. The metal ion uptake capacity of the copolymer have been studied by using the batch equilibrium method and is useful for wastewater treatment. The antimicrobial activity of the copolymers have been studied using the agar diffusion method. Polymer composites have been made from copolymers using an ultra-sonication process and exhibit excellent properties in metal ion uptake for wastewater treatment. The present review paper involves the study of novel applications of the copolymer resins derived from phenolic compound and nitrogen-containing compound.

Recently, the treatment of bacterial infection has been very worrisome as a decline in antibiotic sensitivity is hitting a majority of the world population. Among many bacterial infection’s causing agents, Enterococcus species and Mycoplasma pneumonia are highly threatening because of their resistance to powerful antibiotics such as vancomycin, erythromycin, and azithromycin. Herein, effect of polar (DMSO, EtOH, MeOH, H2O) solvation on the quantum chemical parameters, molecular structure, spectroscopy, and the antimicrobial potential of p-phenylenediamine-thiosemicarbazide-formaldehyde (PTSF) terpolymer is presented within the framework of density functional theory (DFT), solvation molecular dynamics, and molecular docking approach. Herein, ethanol was keenly observed with the most insightful properties across all analyses specifically by its high energy gap (4.6344 eV) which accounted for the stability of compound. The molecular docking revealed the binding affinities for PSTF with respect to the best docking modes are −4.6 kcal/mol with LYS 288 and bond distance of 2.82 Å for 5V2M and −5.1 kcal/mol with ASN 770 at 2.27 Å, GLU 767 at 2.61 Å, ARG 777 at 3.69 Å, GLU 775 at 2.57 Å, and ALA 763 at 2.86 Å for 6rj1. From the result obtained, the studied compound has higher binding affinity at the active site of 6RJ1 than that of 5V2M. This suggests that PSTF has greater efficacy for inhibiting the growth of M. pneumoniae than vancomycin resistant Enterococcus faecalis. Hence, further in vitro and in vivo studies should delve into the more exploration of the reported ligand.
