2-Benzyloxy-1-naphthaldehyde
In the title compound, C(18)H(14)O(2), the dihedral angle between the phenyl and naphthyl ring systems is 21.8 (3)°. The packing of mol-ecules in the crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کامل2-hydroxy-1-naphthaldehyde 2-methylthiosemicarbazone.
Ligands of the aroylhydrazone class have shown much promise as potential chelators for treatment of iron overload disease and perhaps cancer (Johnson et al., 1982; Baker et al., 1992; Richardson et al., 1995; Richardson & Milnes, 1997). Our previous investigations have demonstrated that 2-hydroxy-1naphthaldehyde isonicotinoyl hydrazone, (II), and several other aroylhydrazone chelators possess a...
متن کاملIdentification of essential histidine residues of aminoacylase by photooxidation and by reaction with diethylpyrocarbonate.
State and function of the histidine residues of aminoacylase were investigated by photoxidation in the presence of methylene blue and by chemical modification with diethylpyrocarbonate. Complete inactivation of the enzyme was observed after oxidation of 4 histidine residues. From the pH dependence of the photooxidation it becomes evident that the inactivation of the enzyme is not a consequence ...

Suinizary. A nunibl)er of pteridfines were examined( for activity in promotinig photop)hosphorylation in broken spinach chlioroplasts anid in stimlulating cvtochrome c photooxidation ill sonicated chloroplasts. Correlation was fouind between activities for the 2 reactions. Photophosphorylation promoted by pteridines was inhibited by DCMU and by anaerobic conditiolns. It is concluded that pterid...
متن کاملPhotooxidation of cytochrome P450-BM3.
High-valent iron-oxo species are thought to be intermediates in the catalytic cycles of oxygenases and peroxidases. An attractive route to these iron-oxo intermediates involves laser flash-quench oxidation of ferric hemes, as demonstrated by our work on the ferryl (compound II) and ferryl porphyrin radical cation (compound I) intermediates of horseradish peroxidase. Extension of this work to in...
