A pinoresinol–lariciresinol reductase homologue from the creosote bush (Larrea tridentata) catalyzes the efficient in vitro conversion of p-coumaryl/coniferyl alcohol esters into the allylphenols chavicol/eugenol, but not the propenylphenols p-anol/isoeugenol
The creosote bush (Larrea tridentata) accumulates a complex mixture of 8-8' regiospecifically linked lignans, of which the potent antioxidant nordihydroguaiaretic acid (NDGA) is the most abundant. Its tetra-O-methyl derivative (M4N) is showing considerable promise in the treatment of refractory (hard-to-treat) brain and central nervous system tumors. NDGA and related 9,9'-deoxygenated lignans are thought to be formed by dimerization of allyl/propenyl phenols, phenylpropanoid compounds that lack C-9 oxygenation, thus differentiating them from the more common monolignol-derived lignans. In our ongoing studies dedicated towards elucidating the biochemical pathway to NDGA and its congeners, a pinoresinol-lariciresinol reductase homologue was isolated from L. tridentata, with the protein obtained in functional recombinant form. This protein efficiently catalyzes the conversion of p-coumaryl and coniferyl alcohol esters into the corresponding allylphenols, chavicol and eugenol; neither of their propenylphenol regioisomers, p-anol and isoeugenol, are formed during this enzyme reaction.
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 July 2026.
All research outputs
#5,140,676
of 34,360,257 outputs
Outputs from Archives of Biochemistry & Biophysics
#507
of 7,891 outputs
Outputs of similar age
#16,272
of 121,154 outputs
Outputs of similar age from Archives of Biochemistry & Biophysics
#8
of 35 outputs
Altmetric has tracked 34,360,257 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 7,891 research outputs from this source. They receive a mean Attention Score of 4.7. This one has done well, scoring higher than 86% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 121,154 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 80% of its contemporaries.
We're also able to compare this research output to 35 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
