The title compound, C(14)H(12)ClNO, is a Schiff base derived from the condensation of equimolar quanti-ties of 5-chloro-salicylaldehyde and 1-benzyl-amine. The mol-ecule has a trans configuration with respect to the imine C=N double bond. The N atom is involved in an intra-molecular O-H⋯N hydrogen bond.
Pseudomonas ATCC 17483 produced enzymes for naphthalene metabolism when growing in a medium containing succinate and naphthalene. Mutants for naphthalene metabolism produced by treatment with N-methyl-N'-nitro-N-nitrosoguanidine were able to produce these enzymes only when the metabolic pathway was intact as far as salicylaldehyde, which was therefore identified as the first possible inducer.
The title Schiff base compound, C(15)H(14)N(2)O(3), was derived from the condensation reaction of salicylaldehyde with 4-methoxy-benzohydrazide. The dihedral angle between the two benzene rings is 2.5 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b axis.
Pyridoxal dehydrogenase is specific for DPNf and does not oxidize benzaldehyde, acetaldehyde, salicylaldehyde, or Sdeoxypyridoxal. In the presence of the latter compound, oxidation of pyridoxal is stimulated, apparently because of the occurrence of the dismutation reaction (ii). Z-Demethyl-Z-ethylpyridoxal is dehydrogenated at the same rate as pyridoxal. At high substrate concentrations the pH
An 1,3-indanedione-derived donor–acceptor cyclopropane, bearing the ethoxymethyl-protected phenolic group at ortho-position of donor aryl substituent, has been synthesized using a reaction sequence involving Knoevenagel condensation 1,3-indanedione with corresponding protected salicylaldehyde followed by Corey–Chaykovsky cyclopropanation obtained adduct dimethylsulfoxonium methylide. The struct...
Aroylhydrazones derived from salicylaldehyde are compounds with interesting biological properties including a high anticancer activity. Salicylaldehyde benzoylhydrazone (SBH) is an unusually potent inhibitor of DNA synthesis and cell growth in a variety of cultured human and rodent cells. Various derivatives of SBH have been synthesized in order to discover new more effective antiproliferative ...
The title compound, C(15)H(13)BrClNO, is a Schiff base derived from the condensation of equimolar quanti-ties of 3-bromo-5-chloro-salicylaldehyde and 1-phenyl-ethanamine. The structure displays a trans configuration with respect to the imine C=N double bond. The N atom is also involved in an intra-molecular O-H-N hydrogen bond, which stabilizes the configuration of the compound.
