Four new Schiff bases of 1,10-phenanthroline-2,9-dicarboxaldehyde with sulfur-containing amines such as 2-mercaptoaniline, S-alkyl/aryl dithiocarbazates and thiosemicarbazide have been synthesized and characterized by spectroscopic and X-ray crystallographic techniques. A comparative study of the methods of synthesis has been made using both traditional and microwave techniques. A significant r...

Phosphamidon, a systemic organophosphate insecticide, (1.4 mg/kg - dose 1/4th of LD50 given ip), produced several autonomic, neurological and behavioral effects in mice with peak effects being at 15 min. Similar dose in rats also abolished conditioned avoidance response. Pre-treatment with atropine, iproniazid, alpha-methyl-p-tyrosine, p-chlorophenylalanine or thiosemicarbazide reduce many of t...

A series of 1,4-dihydropyridine derivatives (1a-g) were prepared from three compounds condensation reaction of ethylacetoacetate, aromatic aldehyde and ammonium hydroxide. A new series of compounds (2a-g) were prepared from compounds (1a-g) via reaction with thiosemicarbazide using the condensation method. The synthesized compounds were confirmed by IR, 1H NMR, 13C NMR, mass spectral and elemen...

Antimicrobial screening of several novel pyrazolothiazol-4(5H)-one derivatives (3a-3j) has been performed. Reaction of aromatic aldehydes with aromatic ketones yielded starting chalcones (1a-1j) which have been subsequently reacted with thiosemicarbazide for obtaining N-thiocarbamoylpyrazole derivatives (2a-2j). These were further cyclized to pyrazolothiazol-4(5H)-one derivatives (3a-3j) in the...

The new ligand HMeATSM, derived from condensation of 2-3-butanedione with 4-methyl-3-thiosemicarbazide and 2,4-dimethyl-3-thiosemicarbazide, has been synthesized. Its reactivity nickel(II) zinc(II) nitrates was explored the resulting complexes were thoroughly characterized by elemental analysis, conductivity, mass spectrometry, IR, 1H 13C NMR spectroscopies their structures confirmed single-cry...
