Polytolypin [1], a new pentacyclic triterpenoid exhibiting antifungal and antibiotic activity, has been isolated from cultures of Polytolypa hystricis (JS189), a fungal colonist of porcupine dung. Two known compounds [2 and 3] were also isolated. Polytolypin was obtained by chromatographic fractionation of the EtOAc extract of P. hystricis liquid cultures, and the structure was assigned on the basis of 2D nmr and hrms data.
This research output has an Altmetric Attention Score of 6. 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 09 July 2025.

#7,582,403
of 34,364,397 outputs
Outputs from Journal of Natural Products
#1,489
of 7,229 outputs
Outputs of similar age
#20,079
of 84,884 outputs
Outputs of similar age from Journal of Natural Products
#193
of 1,236 outputs
Altmetric has tracked 34,364,397 research outputs across all sources so far. This one has received more attention than most of these and is in the 73rd percentile.
So far Altmetric has tracked 7,229 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.5. This one has gotten more attention than average, scoring higher than 66% 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 84,884 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 62% of its contemporaries.
We're also able to compare this research output to 1,236 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 65% of its contemporaries.
