The title compound, [Ag(C9H13N5S)Cl(C18H15P)2], crystallizes with four independent mol-ecules in the asymmetric unit, in each of which the Ag atom is in a distorted tetra-hedral coordination, defined by the chloride ligand, the S atom of the neutral ligand and two P atoms derived from the triphenyl phosphine ligands. The thio-semicarbazone acts as a monodentate ligand through its thione S atom....

Syntheses of steroidal heterocycles containing a five-membered N,S- heterocycle attached at the 6,7 positions of the B ring are reported. 5Alpha-cholestane-6-one (1), its 3beta-acetoxy- (2) and 3beta-chloro- (3) analogues reacted with semicarbazide and aqueous sodium acetate in refluxing ethanol to yield 5alpha-cholestan-6-one-semicarbazone 1a and its 3-beta-acetoxy and 3beta-chloro derivatives...

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...

OBJECTIVE Benzophenone semicarbazone (BSC) was synthesized and characterized to identify compounds with anticancer activities. METHODS Anticancer activities were studied against Ehrlich Ascites Carcinoma (EAC) cells in Swiss albino mice by monitoring parameters such as tumor weight measurement, survival time of tumor bearing mice, tumor cell growth inhibition, and so on. Some hematological pa...

A series of hydroxyl semicarbazone derivatives of substituted diaryl ketones and acetophenones were synthesized and their structures were confirmed by analytical and spectroscopic methods including elemental analysis, infrared and nuclear magnetic resonance spectroscopy. The derivatives were prepared by a condensation reaction between N-hydroxy semicarbazide and substituted diaryl ketones or ac...

In the present study a series of methylphenylsemicarbazones was synthesized and evaluated for their analgesic activities by writhing, hot plate and formalin induced paw licking animal model. Most of the compounds were found to be more or comparable potent than the reference standard drug in all the three animal models. Based on the results of analgesic study It was found that chloro substitutio...

The crystal structure and the conformation of the title compound, C22H27N3O7S, were determined from the synthetic pathway and by X-ray analysis. This compound is a new 4-thia-zolidinone derivative prepared and isolated as pure product from thio-semicarbazone carvone. The mol-ecule is built up from an oxo-thia-zolidine ring tetra-substituted by a meth-oxy-oxo-ethyl-idene, a maleate, an oxygen an...

In the title compound, [Ni(C8H14N6S2)], the Ni(II) ion is coordinated by N2S2 donor atoms of the tetradentate thio-semicarbazone ligand, and has a slightly distorted square-planar geometry. In the crystal, inversion-related mol-ecules are linked via pairs of N-H⋯N and N-H⋯S hydrogen bonds, forming R 2 (2)(8) ring motifs. Mol-ecules are further linked by slightly weaker N-H⋯N, N-H⋯S and C-H⋯S hy...
