Fungal Biotransformation Products of Dehydroabietic Acid [PDF]

Journal of Natural Products, 2007
Dehydroabietic acid (DHA) (1) is one of the main compounds in Scots pine wood responsible for aquatic and microbial toxicity. The degradation of 1 by Trametes versicolor and Phlebiopsis gigantea in liquid stationary cultures was followed by HPLC-DAD-ELSD. Both fungi rapidly degraded DHA relative to a control. More breakdown products were observed for T.

Hydroxylation of dehydroabietic acid by Fusarium species

Phytochemistry, 1997
A novel compound, 1 beta-hydroxydehydroabietic acid has been obtained by the microbial transformation of dehydroabietic acid, using cultures of Fusarium oxysporum and F. moniliforme. Its antibacterial activity was also tested.

Bioconversion of ecotoxic dehydroabietic acid using Rhodococcus actinobacteria

Journal of Hazardous Materials, 2018
Actinobactrial strains Rhodococcus erythropolis IEGM 267 and R. rhodochrous IEGM 107 were used to study biodegradation of dehydroabietic acid (DHA), a toxic tricyclic diterpenoid. The experiments were carried out in batch cultures of pre-grown rhodococci in the presence of 0.1% (v/v) n-hexadecane under aerobic conditions for 7 days. It was shown that R.

The alkylation of the amides of dehydroabietic acid

New frontiers in natural product chemistry, 2023
In this abstract is being discussed the synthesis of new substituted amides of dehydroabietic acid with different bromides in system K2CO3/DMF. It is known fact that many compounds, such as famous isatine 1, have the amide group in its molecule. There is no point in talking about it, because everything is known regarding chemical properties.

Metabolites of (+)-dehydroabietic acid in rabbits

Journal of Pharmaceutical Sciences, 1990
The seven metabolites of (+)-dehydroabietic acid (DHA) were newly isolated from rabbit urine by liquid chromatography. On the basis of chemical and spectral data their structures were established to be (15S)-8,11.13-abietatrien-16,18-dioic acid, 2 alpha-hydroxy-8,11,13,15-abietatetraen-18-oic acid, (15R)-15,16-dihydroxy-8,11,13-abietatrien-18-oic acid,

Effects of dehydroabietic acid on the erythrocyte membrane

Chemico-Biological Interactions, 1991
The effects of dehydroabietic acid (DHAA), a dominant resin acid in pulp and paper mill effluents, on membrane-connected events were studied in human erythrocytes. Fifty percent haemolysis was achieved by 252 microM DHAA after 1 h of incubation at +37 degrees C.
