Description

ent-kaur-16-en-19-oic acid is a diterpenoid belonging to the chemical class of ent-kauranes. Its chemical structure features a complex arrangement of carbon atoms, characterized by a fused ring system and specific functional groups that contribute to its biological activity. This compound is involved in various biochemical pathways, including glycosylation reactions, as demonstrated by the recombinant LbUGT enzyme, which catalyzes the β-1,6-glucosylation at C19, leading to the formation of a monoglucosyl derivative (PMID:37571023 ). Additionally, ent-kaur-16-en-19-oic acid has been shown to exhibit anti-inflammatory properties, particularly through modulation of the NF-κB, MAPK, and mTOR pathways, as well as influencing autophagy in LPS-stimulated macrophages (PMID:33705895 ). Its activity has been compared to that of its analogs, indicating a significant role in therapeutic applications. Furthermore, it has been isolated from various plant sources, such as Baccharis sphenophylla and Wedelia trilobata, highlighting its prevalence in nature and potential utility in pharmacological research (PMID:34063939 , PMID:33645029 ).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as kaurane diterpenoids. These are diterpene alkaloids with a structure that is based on the kaurane skeleton. Kaurane is a tetracyclic compound that arises by cyclisation of a pimarane precursor followed by rearrangement. It possesses a [3,2,1]-bicyclic ring system with C15-C16 bridge connected to C13, forming the five-membered ring D.
