Curator's Comment: description was created based on several sources, including: https://en.wikipedia.org/wiki/Isopimaric_acid | https://www.ncbi.nlm.nih.gov/pubmed/12237330 | https://www.ncbi.nlm.nih.gov/pubmed/27308214

Isopimaric acid is a widely available tricyclic diterpenoid well represented in the resin of conifers of the genera Pinus, Larix, and Picea. It exhibits interesting biological and pharmaceutical properties such as antimicrobial, antiviral, antiallergenic, and anti‐inflammatory activities. It acts as a large conductance Ca2+activated K+ channel (BK channel) opener. BK channel openers have emerged as potentially useful agents in the therapy of various diseases associated with both the central nervous system and smooth muscle system.
