acylisothiocyanate (1) was allowed to react with benzylidene malononitrile producing oxazine derivative (2). also, compound (1) was reacted with sodium azide followed by refluxing with sodium ethoxide affording thiazinotetrazole derivative (4). the reaction of acetylacetone with compound (1) gave pyridine derivative (5) by intramolecular cycloaddition while it was reacted with n-methyl aniline ...

There are some reports which indicate that several triazole derivatives have inotropic activity; however, the cellular site and mechanism of action at cardiovascular level is very confusing. In order, to have a clear understanding of these phenomena, a triazole derivative was synthesized to evaluate its biological activity on left ventricular pressure and characterize the molecular mechanism. T...

In the title compound, C(15)H(12)Cl(2)N(4)S·C(15)H(10)Cl(2)N(4)S·C(2)H(6)O, the two chloro-phenyl rings of the triazole derivative form dihedral angles of 65.7 (2) and 44.2 (2)° with the triazole ring. In the thio-carbonohydrazide derivative, the dihedral angle between the two chloro-phenyl rings is 5.4 (2)°. In the crystal, the triazole, thio-carbonohydrazide and methanol mol-ecules are linked...

Purpose: To synthesize new triazole derivatives in order to overcome the problem of side effects antimicrobial agents and microbial resistance, while broadening spectrum activity.
 Methods: The starting triazole, compound 1, was prepared through click chemistry reacted with chloroacetyl chloride yield II. Triazole 1 acids aldehydes produce oxadiazole (III) azomethine (IV) which cyclized ac...

The scope of the current work was to synthesize an S-alkylated 1,2,4-triazole-3-thiol derivative. Synthesis carried out in two steps: first step, 4,5-diphenyl-4H-1,2,4-triazole-3-thiol using a halogenated acetal and cesium carbonate. In second several deprotection procedures were tested, aldehyde obtained isolated as bisulfite adduct. structures new compounds characterized by FT-IR, 1D, 2D NMR ...

An efficient, safe and improved process for the preparation of ticagrelor 1, a platelet aggregation inhibitor is described. Synthesis comprises the condensation of pyrimidine amine derivative 14 with cyclopentyl derivative 13 in ethylene glycol followed by construction of triazole compound 16 by diazotization of the obtained intermediate 15 with a green and safer reagent "Resin-NO2" in water an...

2-Aryl-1-azolyl-3-(substituted amino)-2-butanol derivatives I were prepared by ring-opening reaction of epoxides II with excess amine, and their antifungal activities were evaluated as topical agents. Azolyl-cyclic amine derivatives with a methylene group showed extremely strong activity with a broad spectrum in vitro. In general, anti-Trichophyton mentagrophytes activities of most of the topic...

The natural amide bond found in all biotinylated proteins has been replaced with a triazole through CuAAC reaction of an alkynyl biotin derivative. The resultant triazole-linked adducts are shown to be highly resistant to the ubiquitous hydrolytic enzyme biotinidase and to bind avidin with dissociation constants in the low pM range. Application of this strategy to the production of a series of ...

The redox mechanism of two trisubstituted triazole-linked phenyl derivatives (CL41 and CL42) and a disubstituted triazole-linked phenyl derivative (CL2r50) were studied using cyclic, differential pulse and square wave voltammetry at a glassy carbon electrode. The CL41, CL42 and CL2r50 oxidation is a complex, pH-dependent irreversible process involving the formation of electroactive products tha...
