Purpose Paper aims to Preparation and evaluation of isoxazole benzene sulfonamide derivatives and incorporated it with waterborne household paints to develop coating compositions as an insecticidal coating against Musca domestica adults. Design/methodology/approach The synthesized compounds were prepared and confirmed by different analyzes, fourier transform infra-red (FTIR), mass, proton nuclear magnetic resonance (1HNMR) and Carbon 13 nuclear magnetic resonance (13CNMR) spectra. The prepared compound has been blended with waterborne household paint formulation, the physical and mechanical properties of the paint formulation has been studied. The efficiency of the isoxazole benzene sulfonamide derivatives when incorporated with waterborne paint against Culex quinquefasciatus and Mosquito house fly adults, also have been examined. Findings The obtained results of the paint formulations confirmed their best performance and providing good scrub resistance. Also, the finding promising results of the insecticide test of the paint formulation may be because of the biological activity of these compounds and containing sulfonamide, cyanide and free aromatic amine groups comparing with the standard recommended organophosphorus insecticide. The order activity increase with increasing the dose concentration of the isoxazole derivatives and the activity of chemical compounds itself is represented in terms of their medium lethal concentrations LC50 (LC90), which recorded 0.90(1.62), 0.89(1.61) and 0.86(1.56) g/ml for 5, 3 and 4 chemical compounds, respectively, after 72 h from treatment. Practical implications These types of organic compounds are friendly environmentally and can be used as a biocide with different types of paint formulations. Originality/value Insecticide waterborne household paints based on isoxazole benzene sulfonamide derivatives as insecticide agents are novel.

Purpose In this study, two novel fluorescent dyes, based on naphthalimide derivatives have been synthesised from acenaphthene as a starting material. The ability of the dyes to graft to polymer chain was then demonstrated. The novel synthesised dyes and self-coloured polymers were characterised by a variety of techniques. Design/methodology/approach The novel dyes were prepared through by halogenation, oxidation, imidation and amination reactions. All steps of these processes were monitored by thin layer chromatography. The fluorescent dyes and their intermediates were characterised by differential scanning calorimeter, fourier transform infrared spectroscopy (FTIR), Proton Nuclear Magnetic Resonance (1H-NMR) and carbon-13 nuclear magnetic resonance (13-CNMR) spectroscopic techniques. The molar extinction coefficients and absorption maximum wavelength were obtained by examining the dyes and polymer solutions in Dimethylformamide (DMF) and toluene solvents. The fluorescency of novel dyes and self-coloured polymers was evaluated. Their quantum yields and Stokes shift values were determined as DMF and toluene solutions. The percentage of the covalently bounded dyes into the polymer chain was calculated. Findings The characterisation of the synthesised dyes and self-coloured polymers verified their structural correctness. The results of reaction dyes with resin demonstrated that the dyes were covalently bonded to the chain of an acrylic polymer (resin) containing carboxylic acid groups giving self-coloured polymers. The extent of fluorescence of the synthesised dyes and their polymers showed that compounds containing functional amino group in C-4 position of naphthalimide ring have high fluorescence properties. Originality/value This study is original. Self-coloured polymers based on acrylic were synthesised by novel naphthalimide dyes with acrylic resin for the first time, successfully. The novel dyes and their self-coloured polymers exhibit good and acceptable fluorescent activity.

Purpose The purpose of this paper is to prepare new disperse dyes and apply for dying polyester fabrics. Design/methodology/approach The synthetic reaction was carried out through two steps: preparation of arylhydrazones and alkylation using enaminone and dimethylaminovinyl-pyridazine. The high temperature method was used to apply these dyes to polyester fibres. Findings The study revealed that there is a significant effect of the new prepared disperse dyes on polyester fabrics. The structures of the prepared dyes were established based on elemental analysis and spectral data (infra red (IR), mass spectrometry (MS) and proton nuclear magnetic resonance (1H-NMR), carbon 13th nuclear magnetic resonance (13C-NMR)). Research limitations/implications Disperse dyes containing heterocyclic moiety have attracted great academic and industrial attention owing to their significant. The potential of using disperse dyes easily prepared from arylhydrazones are promise broad applications for these dyes. Practical implications The presence of N-thienyl and N-pyridazinyl in the structure of the synthesised disperse dyes would be expected to add the bioactivity advantage. Also, it can be used in formulating the antimicrobial fabrics. Social implications The N-thienyl and N-pyrdiazinyl derivatives of azo dyes are expected to be superior to in the application for fabrics. It may be useful for other applications like painting. Originality/value This paper helps to synthesise novel thiophene or pyridazine-based dyestuff for application in dying properties on polyester fabric and study their fastness properties.

The 1,2,3-triazole is a well-known biologically active pharmacophore constructed by the copper-catalyzed azide–alkyne cycloaddition. We herein reported the synthesis of 4-amino-7-chloro-based [1,2,3]-triazole hybrids via Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition of 4-azido-7-chloroquinoline with an alkyne derivative of acetaminophen. The compound was fully characterized by Fourier-transform infrared (FTIR), proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), heteronuclear single quantum coherence (HSQC), ultraviolet (UV) and high-resolution mass spectroscopies (HRMS). This compound was screened in vitro with different normal and cancer cell lines. The drug likeness of the compound was also investigated by predicting its pharmacokinetic properties.
