“…In recent years, s -triazoles and their fused heterocyclic derivatives have received much interest due to their effective medicinal importance. There are many marked drugs, such as triazolam, alprazolam, and etizolam, containing the s -triazole group. − In the past decade, several applications of heterocyclic compounds containing nitrogen atoms have been reported. − Biological activities; biomedical uses; and commercial applications such as dyes, insecticides, and herbicides of s -triazoles linked to heterocyclic rings have also been demonstrated. − Recently, derivatives carrying the s -triazole moiety possess a wide spectrum of chemotherapeutic activities including antiviral, antifungal, , anthelmintic, antitumor, − antibacterial, anti-inflammatory, − antitubercular, analgesic, , antipyretic, , and anticancer activities . Indeed, some of these derivatives were actually active ingredients of drugs .…”

“…Additionally, the isolated product 15a showed a singlet signal at δ = 2.29 and 2.45 ppm attributed to CH 3 and CH 3 triazole, respectively (Figure S48). The 13 For instance, the contaminants under investigation were cadmium and lead ions as heavy metal ions, and the anions were fluoride, chloride, and sulfate. Batch adsorption tests were used in the adsorption studies to assess the efficacy of the produced compounds based on the s-triazole moiety.…”

A rapid, efficient, and one-pot protocol has been developed for the synthesis of cyclized 2,6-dimethyl-5-substituted-thiazolo[3,2-b]-s-triazoles (3a–c) through the interaction of 5-methyl-1H-s-triazole-3-thiol (1) with aliphatic ketones (2a–d) in refluxing acetic acid in the presence of a catalytic amount of sulfuric acid (AcOH/H+) while with aromatic ketones (5a–d), a mixture of uncyclized 3-methyl-s-triazolylthioacetophenone derivatives (6a–d) and cyclized 6-aryl-2-methyl-thiazolo[3,2-b]-s-triazoles (7a–d) has been produced. With this catalytic system, inexpensive sulfuric acid was utilized as a catalyst, which prevented the production of poisonous and irritating halo carbonyl compounds. On the other hand, the interaction of s-triazole 1 with cyano compounds (9a,b) afforded the corresponding 6-amino-2-methyl-5-substituted-thiazolo[3,2-b]-s-triazoles (10a,b). Similarly, treatment of 4-amino-3-methyl-s-triazole-5-thiol (12) with aliphatic and aromatic ketones (2c and 5a–e) afforded directly 3-methyl-7H-s-triazolo[3,4-b]-1,3,4-thiadiazines (13a and 14a–e). Further, reaction of 12 with cyano compounds (9a,b) under the same reaction conditions yielded the corresponding 3-methyl-s-triazolo[3,4-b]-1,3,4-thiadiazole derivatives (15a,b). The reaction mechanism was studied, and the structures of all novel compounds were verified using spectroscopy and elemental analysis. Moreover, the potential application of the synthesized compounds toward heavy metal ions and inorganic anion removal from aqueous solution has been investigated. The removal effectiveness for metal ions reached up to 76.29%, while for inorganic anions it reached up to 100%, indicating that such synthesized compounds are promising adsorbents for water remediation.

Two-bath dyeing is currently used to dye cotton/nylon blended fabrics. The cotton/nylon blended fibers were initially pretreated independently with metal oxides based nanoparticles (NPs) before being dyed with acid and reactive dyestuffs. Two baths were used for dyeing of NPs metal oxides pre-treated cotton/nylon fabric with reactive and acid dyes. The morphological properties of the treated fabrics were explored by scan electron microscope and energy-dispersive X-ray. The impact of pre-treatment with NPs metal oxides on dye-ability, colorfastness, and physico-chemical features has been studied. Colorimetric strength (K/S) and CIE Lab were also explored. K/S values, washing, perspiration, and light fastness of the cotton/nylon sample treated with metal oxide nanoparticles were all higher. Antimicrobial activity was also examined against strains of K. pneumoniae, S. aureus and Candida albicans. The findings indicating that colored fabric had antibacterial potential due to the antibacterial property of NPs metal oxides. Aside from the NPs-treatment colored fabrics with excellent UV protection properties are produced.
