A simple, sensitive, selective rapid spectrophotometric method has been developed for the determination of synthetic antimicrobial furazolidone in pure form and pharmaceutical formulations based on the oxidative coupling reaction with MBTH reagent, at P4.0 which is extractable at 630 nm. Beer’s law is obeyed in the concentration ranges 10-60 μg ml. And 5-30 μg ml. For blood sample the developed...

A simple, sensitive, selective rapid spectrophotometric method has been developed for the determination of terazosin in pure form, pharmaceutical formulations and blood sample based on the oxidative coupling reaction with MBTH (3-methyl-2-benzothiazolone hydrazone hydrochlorideMethod-A), and Ion association reaction with BPB(Bromophenol Blue-Method-B) reagents at P H_ 4.0 which is extractable a...

Three peroxidase (POD) isoenzymes were purified from a soluble extract of broccoli stems. The acidic and neutral PODs were purified to homogeneity by using ion exchange and hydrophobic chromatography. The basic POD was purified by cation exchange and gel filtration chromatography. The neutral and basic PODs had molecular masses of approximately 43 kDa, and the acidic POD had a molecular mass of...

OBJECTIVE(S) Recently we reported that the soybean 15-lipoxygenase (SLO) inhibitory activity of pyrimido[4,5-b][l,4]benzothiazines largely depends on the orientation of sulfur atom of thiazine core towards Fe(III)-OH in the active site pocket of the enzyme with subsequent oxidation of sulfur to sulfoxide. In this paper the results of a comparative study on the SLO inhibitory activities of the m...
