To discover new 1,2,4-triazole derivatives which may possess significant biological activities, we synthesized a series of novel 6-aryl-3-(D-galactopentitol-1-yl)-7H-1,2,4-triazolo[3,4-b][1,3,4]thiadiazines and 4-(arylmethylidene)amino-5-(D-galactopentitol-1-yl)-3-mercapto-4H-1,2,4-triazoles from 4-amino-3-(D-galactopentitol-1-yl)-5-mercapto-1,2,4-triazole. All the title compounds were characte...

In the title compound, C(17)H(28)N(4)S, the 1,2,4-triazole ring is nearly planar [maximum deviation = 0.005 (2) Å]. There are no significant hydrogen bonds observed in the crystal structure. The crystal studied was a non-merohedral twin, the refined ratio of twin components being 0.281 (3):0.719 (3).

considerable interest has been focused on the triazole structure, which has been known to possess a broad spectrum of biological activities such as antitumor, anti-inflammatory, antimicrobial, antiviral, and anticonvulsant activities. before this, several heterocyclic compounds containing triazole were synthesized that had shown considerable anticonvulsant activity. as part of our continuous re...

The title compound (systematic name: N,N-diethyl-3-mesitylsulfonyl-1H-1,2,4-triazole-1-carboxamide), C16H22N4O3S, is a triazole herbicide. The dihedral angle between the planes of the triazole and benzene ring planes is 88.14 (10)°. In the crystal, C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions link adjacent mol-ecules, forming one-dimensional chains along the a axis.

About half of the drugs currently produced are chiral compounds, and about 90 % these compounds sold as racemates, consisting an equimolar mixture two enantiomers. Although they have same chemical structure, most optical isomers substances show marked differences in biological activity. It is known that presence a single asymmetric atom has become almost integral part advanced drug design. The ...

In the title coordination polymer, [CdCl(2)(C(8)H(8)N(4))(2)](n), the Cd(II) atom, lying on an inversion center, is coordinated by two Cl atoms and two triazole N atoms and two pyridyl N atoms from four 1-(4-pyridyl-meth-yl)-1,2,4-triazole (pmta) ligands in a distorted trans-CdCl(2)N(4) octa-hedral arrangement. The bridg-ing pmta ligands, with a dihedral angle between the triazole and pyridyl r...

Growth of Chlorella vulgaris and Prototheca zopfii is inhibited by treatment with 3-amino-1,2,4-triazole. Growth of these 2 algae in the presence of amino triazole is accompanied by the accumulation in the culture media of the dephosphorylated histidine precursor, imidazoleglycerol. The addition of histidine to the culture media in the presence of amino triazole restored the normal growth rates...
