A series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (C1-C7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. All the synthesis compounds have been characterized by 1HNMR, IR and Mass spectral data. The compounds were purified...

A rapid, simple and cost effective solidified floating organic drop microextraction (SFODME) and flow injection flame atomic absorption spectrometric determination (FI-FAAS) method for copper was developed. In this method, a free microdrop of 1-undecanol containing 1,5-diphenyl carbazide (DPC) as the complexing agent was transferred to the surface of an aqueous sample including Cu(II) ions, whi...

An antiserum to lutein inhibits photosynthetic electron transport between water and potas­ sium ferricyanide in chloroplasts from green Nicotiana tabacum var. John William’s Breadleaf. However, electron transport between diphenylcarbazide and potassium ferricyanide is not impaired. From this it is concluded that the photochemically active carotenoid should feed its electrons into the photosynth...

An antiserum to synthetic Zeaxanthin inhibits photosynthetic electron transport on the oxygen-evolving side of photosystem II in tobacco chloroplasts and thylakoids of the filamentous blue-green alga Oscillatoria chalybea. The inhibition site lies for both species between the site of electron donation of water or tetramethyl benzidine and that of diphenyl carbazide or manganese II ions. Typical...

The title complex, [Zn(CH(5)N(3)S)(2)(C(2)H(6)OS)](C(6)H(2)N(3)O(7))(2)·C(2)H(6)OS·H(2)O, is composed of a [Zn(thio-semi-carbazide)(2)(DMSO)](2+) cation (where DMSO is dimethyl sulfoxide), and two picrate anions. In the asymmetric unit, there is also a solvent mol-ecule of DMSO and a water mol-ecule of crystallization. In the cation, the Zn(II) atom is five-coordinated in a distorted square-pyr...

Spectrophotometric determination of Cr (using 1.5–diphenyl carbazide), in aqueous, sediment and soil samples is reported. Different leaching reagents like 0.5M NaOH-0.28M Na2CO3 and 0.2 M H3PO4 were used for the isolation of Cr from sediment and soil samples. Determination of Cr by using 0.5M NaOH-0.28M Na2CO3 as leaching reagent followed by spectrophotometric measurements provided satisfied re...
