Spectrophotometric determination of pyridoxal and pyridoxal 5'-phosphate with 3-methyl-2-benzothiazolone hydrazone hydrochloride, and their selective assay.
A spectrophotometric method with 3-methyl-2-benzothiazolone hydrazone hydrochloride was developed for the determination of pyridoxal and pyridoxal 5'-phosphate, and for the selective determination of each in the presence of the other. Pyridoxal and pyridoxal 5'-phosphate react with the reagent to yield the azine derivatives, which give characteristic absorption spectra. The highest extinction v...
متن کاملUse of 3-methyl-2-benzothiazolone hydrazone in an automated colorimetric method for determination of triglycerides in plasma or serum.
for the determination of serum or plasma triglycerides. The samples are extracted with 2propanol containing activated alumina. An AutoAnalyzer Sampler II and Proportioning Pump II are used in combination with a Gilford Model 300 N spectrophotometer and Model 3091-A debubbler flow cell. Following on-line saponification, glycerol is oxidatively cleaved with sodium metaperiodate. The resulting for...

permits easy passage across the blood-brain barrier. Others have argued that since brain tumors do not possess a blood brain barrier, the lipid solubility of the nitrosoureas can play no robein their therapeutic effectiveness. We have tested ACNU, a water-soluble nitrosourea, for its chemotherapeutic effect in several animal brain tumor models and have compared ACNU to other more lipid-soluble ...

متن کاملInvestigation of Fullerene effect on reactivity of 2-amino-3-(3,4-dihydroxyphenyl)-2-methyl-propanoic acid with NMR parameters
In this research at the first 2-amino-3-(3,4-dihydroxyphenyl)-2-methyl-propanoic acid drug and its fullerene derivative were optimized. NMR calculations for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemical hardness (η)...
