Leelamine hydrochloride, a tricyclic diterpene extracted from pine tree bark, inhibits the transcriptional activity of the androgen receptor, known to regulate fatty acid synthesis [2,3]. This compound acts as a cannabinoid receptor type 1 (CB1) agonist and suppresses SREBP1-regulated fatty acid/lipid synthesis in prostate cancer cells, irrespective of androgen receptor status.
Isotanshinone IIA, could non-competitively inhibit Protein Tyrosine Phosphatase 1B (PTP1B) activity with an IC50 0f 11.4 μM. is an abietane-type diterpene metabolite.
Acanthoic acid is a pimaradiene diterpene isolated from Acanthopanax koreanum with anti-inflammatory activities. Acanthoic acid downregulates LPS-induced IL-1β, IL-6 and TNF-α production in BALF, attenuates lung histopathologic changes, and inhibits infla
Terpendole C is an indole diterpene alkaloid fungal metabolite originally isolated from A. yamanashiensis and an inhibitor of acyl-coenzyme A:cholesterol acyltransferase (ACAT; IC50 = 2.1 μM in rat liver microsomes). It also inhibits ACAT in J774 macrophages (IC50 = 0.46 μM) without affecting cell growth.
