Photolysis of isoeugenol

Australian Journal of Chemistry, 1977

Deodorants: an experimental provocation study with isoeugenol

Contact Dermatitis, 2005
Axillary dermatitis is common and overrepresented in people with contact allergy to fragrances. Many people suspect their deodorants to be the incriminating products. In order to investigate the significance of isoeugenol in deodorants for the development of axillary dermatitis when used by people with and without contact allergy to isoeugenol, patch ...

Isoeugenol: A survey of consumer patch-test sensitization

Food and Chemical Toxicology, 1983
The potential of isoeugenol, an important fragrance and flavour ingredient, to induce delayed contact hypersensitivity or to elicit pre-existing sensitization reactions in man was evaluated by analysing patch-test data from dermatitic and non-dermatitic subjects.

Oxidation of isoeugenol by Nocardia iowensis

Enzyme and Microbial Technology, 2008
Abstract Isoeugenol is a starting material for both the synthetic and biotechnological production of vanillin and vanillic acid. Nocardia iowensis DSM 45197 (formerly Nocardia species NRRL 5646) resting cells catalyze the conversion of isoeugenol to vanillic acid, vanillin, vanillyl alcohol and guaiacol.

Studies on the Photodimerization of Isoeugenol

Journal of the Chinese Chemical Society, 1978
AbstractUnder the irradiation of the ultraviolet light, Isoeugenol (I) undergoes dimerization in acetone to give diisoeugenol (II) and dehydrodiisoeugenol (III). The structures are determined by the comparison of the mixed m. p., I. R. spectra and T. L. C. with synthesized authentic samples. Also the photoreaction mechanism is discussed in detail.

Isoeugenol's biotransformation to vanillin using microorganisms

American Journal of Chemistry
The biotechnological route of producing natural biological food products is preferred over synthetically created ones. One such pathway is biotransformation, which entails the chemical transformation of one substance into another using microorganisms acting as biocatalysts.

SENSITIZED PHOTOOXIDATION OF ISOEUGENOL TO VANILLIN

Photochemistry and Photobiology, 1979
Abstract— The photochemical conversion of isoeugenol to vanillin can proceed via the 1O2 (1Δg) state of oxygen and can be effected over a wide range of base and dye concentrations. A typical situation involving methylene blue (0.3 mM), isoeugenol (24 mM) and a base concentration of 0.1 N will give yields of approximately 35% of the theoretical amount.

Characterization of an isoeugenol monooxygenase (Iem) from Pseudomonas nitroreducens Jin1 that transforms isoeugenol to vanillin.

Bioscience, biotechnology, and biochemistry, 2013
The isoeugenol monooxygenase (iem) gene from Pseudomonas nitroreducens Jin1, responsible for the conversion of isoeugenol to vanillin, was cloned and overexpressed in Escherichia coli. The purified Iem had a predicted molecular mass of 54 kDa. The V(max), K(M), and k(cat) values for it, using isoeugenol as substrate, were 4.2 µmol vanillin min(-1) mg ...
