A series of 4 – aryl substituted semicarbazones of some terpenes ie , citral ( acyclic terpene ) , camphor ( bicyclic terpene ) and menthone ( monocyclic terpene ) were synthesized from substituted anilines , to meet the structural requirements essential for anticonvulsant activity . The structures of the synthesized terpene semicarbazones were confirmed by I.R. , H-NMR and elemental analysis. ...

in this study a special type of silicoaluminophosphate with opal structure (opal-sapo) was prepared under microwave condition using tetraethylorthosilicate (teos), triethanolamine (tea), aluminiumisopropoxid and phosphoric acid 85%. the product was characterized by x-ray diffraction (xrd), thermogravimetric (tga) and fourier infrared spectroscopy (ftir).the crystalline product showed a good act...

The asymmetric unit of the title compound, C(6)H(11)N(3)O, consists of two independent mol-ecules in which the cyclo-pentane rings adopt envelope conformations with CH(2) grouping as the flap and the semicarbazone groups are essentially planar, with maximums deviation of 0.0311 (12) and 0.0285 (12) Å. In the crystal, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules to form sheets lying...

Series of 3, 4-disubstituted benzaldehyde-N-(6-substituted-1,3-benzothiazol2-yl)semicarbazones (4a-t) were synthesized by condensation of the N(substituted-1,3-benzothiazol-2-yl)hydrazinecarboxamides with aromatic aldehydes and screened for their anticonvulsant activity using the maximal electroshock seizure (MES) method. The selected compounds were checked for the neurotoxicity by rotorod test...

New Schiff bases, hydrazones and semicarbazones derived from 1,2-dihydro-4-hydroxy-6-methyl2-oxoquinoline-3-carbaldehyde, have been synthesized. The semicarbazone was subjected to react with 2,3-dichloroquinoxaline, chloroacetic acid, and oxalyl chloride affording multiaza­ heterocycles substituted to quinolone moiety at position 3. Condensation of the 2-imidazolidinethione derivative with some...

The mixed ligand complexes of the type [ML1L2]Cl2. Where M=Cr(III), Mn(II), Co(II), Ni(II) and Cu(II) and L1=Pyruvic acid semicarbazone L2= Benzaldehyde semicarbazone have been synthesized, by the reactions of metal chlorides with two different semicarbazones in 1:1:1 molar ratios. The resulting products have been characterized on the basis of elemental analysis, magnetic measurement, IR and El...
