anticonvulsant activity of 7-phenyl-5h-thiazolo[5,4-e][1,2,3,4]tetrazolo[5,1-c]pyrrolo[1,2-a][1,4]diazepine (5) and 7-phenyl-5h-thiazolo[5,4-e][1,3,4]triazolo[5,1-c]pyrrolo[1,2-a][1,4]diazepines (6a-d) was measured against pentylenetetrazole (ptz)-induced seizures in mice. intraperitoneal injections of different doses (12.5, 25 and 50 mg/kg, i.p.) of test compounds decreased ptz-induced seizure...

BACKGROUND 1,2,4-Triazole3-thiones are good scaffolds for preparation of new lead compounds. Their derivatives attracted the attention of chemists due to their wide spectrum of biological activities. Alkylsulfanyl-1,2,4-triazoles have three nucleophilic sites (nitrogens) ready for reaction with electrophiles. Herein, new regioselective isomers were synthesized by the reaction of benzylsulfanyl-...

The organic mol-ecule and uncoordinated water mol-ecule in the crystal of the title compound, C(25)H(24)N(4)O(4)·2H(2)O, both lie on special positions of twofold symmetry. A twofold rotation axis passes through the methyl-ene C atom connecting the two dihydro-benzopyrrolodiazepindionyl parts. The seven-membered C(5)N(2) ring adopts a boat conformation.
