The ligands 1-(cyclohexyl)-4-(2-pyridyl)-1,2,3-triazole (1), 1-(2,6-diisopropylphenyl)-4-(2-pyridyl)-1,2,3-triazole (2), 1-(4-butoxyphenyl)-4-(2-pyridyl)-1,2,3-triazole (3) and 1-(methyl)-4-(2-pyridyl)-1,2,3-triazole (4) were synthesized by the Cu(I) catalyzed "Click" reaction between 2-pyridylacetylene and the corresponding azides. The ligands were then reacted with NiBr(2)·3H(2)O to generate ...

A series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. Some of the tested compounds were active against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Clostridium difficile, Aspergillus niger and Cryptococcus neoformans.

Trinucleotide CAG repeat expansion in the coding region of genes has a propensity to form polyglutamine (polyQ) aggregates that contribute to neuronal disorders. Strategies in elevating autophagy to disintegrate the insoluble aggregates without injuring cells have become a major goal for therapy. In this work, a triazole derivative, OC-13, was found accelerating autophagic clearance of polyQ ag...

A β-aminoacid ester was successfully derivatized to yield to 4H-1,2-4-triazol-4-yl-propionate (βAlatrz) which served as a neutral bidentate ligand in the 1D coordination polymer [Fe(βAlatrz)(3)](CF(3)SO(3))(2)·0.5H(2)O (1·0.5H(2)O). The temperature dependence of the high-spin molar fraction derived from (57)Fe Mossbauer spectroscopy recorded on cooling below room temperature reveals an exceptio...

Series of novel dichromophoric cyanine dyes based on 2-aminobenzothiazoles and 3-amino-1,2,4 -triazole have been synthesized in high yields. All the dyes have been classified as disperse dyes. Besides their electronic spectroscopic properties, high dye-uptakes on polyester, excellent fastness properties, highly extinction coefficients, and broad solvatochromic effects have been observed in thes...

A series of novel xylitan derivatives derived from xylitol were synthesized using operationally simple procedures. A xylitan acetonide was the key intermediate used to prepare benzoate, arylsulfonate esters and 1,2,3-triazole derivatives of xylitan. These compounds were evaluated for their in vitro anti-Trypanosoma cruzi activity against trypomastigote and amastigote forms of the parasite in T....

A peptide sequence N(3)-GVGV-OMe (G: glycine; V: valine) was attached to a benzene 1,3,5-tricarboxamide (BTA) derivative via"click chemistry" to afford a C(3)-symmetric artificial oligopeptide. The key feature of this oligopeptide is that the binding sites (triazole groups formed by click reaction) are located at the center, while the three oligopeptide arms with a strong tendency to assemble a...

The title ibuprofen-containing Mannich derivative, C(26)H(32)N(6)O(3)S, crystallizes with two independent mol-ecules in the asymmetric unit. The morpholine ring in each mol-ecule adopts a chair conformation. The 1,2,4-triazole ring forms dihedral angles of 2.13 (10) and 75.52 (10)° with the two substituted benzene rings in one mol-ecule, with corresponding values of 19.36 (11)° and 89.03 (10)° ...

In the asymmetric unit of the title adamantyl derivative, C(20)H(25)N(3)S, there are two crystallographic independent mol-ecules with slightly different conformations. In one mol-ecule, the whole benzyl group is disordered over two orientations with the refined site-occupancy ratio of 0.63 (2):0.37 (2). The dihedral angles between the 1,2,4-triazole and phenyl rings are 24.3 (8) (major componen...
