Differently from the effect of diamide that caused reversible changes, after phenylhydrazine
treatment, band 3 oxidation, and its phosphorylation, Syk translocation to the membrane and its phosphorylation increased progressively, paralleling the generation of hemichromes (Figure 5).
The aim of the study was to identify the changes of the frequency amplitude of spontaneous rhythmic contractions of the thoracic duct at acute and chronic intoxication with phenylhydrazine
and on the correction drug Salsocollin.
The reaction is shown for phenylhydrazine
in Scheme 4.
Derivatization of MMDA and MDA with phenylhydrazine
yielded 4-methyl-1-phenylpyrazole and 1-phenylpyrazole, respectively.
McDonald, Insecticidal phenylhydrazine
8) uses phenylhydrazine
at 70 [degrees]C in an oxidizing medium on latex, which produces LNR with a molecular weight, according to time, of 3,000 to 20,000.
Among these frequently used reagents are 2,4-dinitro- phenylhydrazine
[29-30], 4-hydrazine-2- stilbanzole , o-phenylenediamine [32, 33], 1,2- diamino-4,5-dimethoxybenzene , 1,2-diamino-4,5-methylenedioxyb enzene  and 4,5- diaminophthalhydrazide .
1, Dimethyl sulfoxide, cytochrome C, superoxide reductase, xanthinoxidase, xanthine, glutathione, o-phthaldialdehyde (OPT) and 2,4 dinitro phenylhydrazine
(DNPH) were purchased from Wako Pure Chemical Industries (Osaka, Japan).
0, acetylation + PAS, acetylation + deacetylation + PAS, acid hydrolysis + PAS, phenylhydrazine
+ PAS and thiosemicarbazide + PAS.
2] was then added, and the sample derivatized with 1 [micro]mol of phenylhydrazine
for 30 min at room temperature (final volume, 0.
A well-known similar reaction takes place between some diamines, such as phenylhydrazine
, and compounds such as glucose or anhydroglucose.
Condensation of 5-acetyl- 1,2,4-triazines 4a-e with phenylhydrazine
derivatives in ethyl alcohol containing catalytic amount of hydrochloric acid formed appropriate arylhydrazone of 5-acyl-1,2,4-triazine 6-36 in excellent yield [13, 17, 18, 21].
