Homoharringtonine (HHT) is a natural alkaloid that inhibits the translation of proteins and is cytotoxic. Homoharringtonine acts on the ribosomes of tumor cells to inhibit the elongation step of protein translation, thereby inhibiting protein synthesis, and has antitumor activity.

12(S)-HHT (12(S)-HHTrE), a fatty acid produced via the arachidonic acid metabolic pathway of cyclooxygenase (COX), is an endogenous ligand and agonist of BLT2, and the 12(S)-HHT BLT2 axis plays a role in the maintenance of homeostatic aspects of epithelial tissues and in inflammatory responses. 12(S)-HHT inhibits the p38 MAPK NF-κB pathway through upregulation of MKP-1, leading to reduced IL-6 synthesis in UVB-irradiated HaCaT cells.

Elaidic acid (trans-Oleic Acid) is the 9-trans isomer of oleic acid. It is a monounsaturated trans-fatty acid which can be found in partially hydrogenated cooking oils. In human platelets incubated with arachidonic acid, elaidic acid inhibits HHT and HETE formation while inducing prostaglandin and thromboxane synthesis.

2,3,5,4'-Tetrahydroxystilbene 2-O-β-D-glucoside (Astragalus polyphenols) is a compound isolated from the roots of Polygonum species, which inhibits the formation of 5-HETE, HHT, and thromboxane B2.

Mulberrofuran Q is an active compound that inhibits the formation of 12-hydroxy-5,8,10-heptadecatrienoic acid (HHT) and thromboxane B2 (cyclooxygenase product) , which protects neuronal cells from hypoxia-glycorrhoea-deficiency (OGD)-induced oxidative stress.

Mulberrofuran A can inhibit the formations of 12-hydroxy-, 8, 10-heptadecatrienoic acid (HHT) and thromboxane B2, but it can increase the formation of 12-hydroxy-5, 8, 10, 14-eicosatetraenoic acid (12-HETE).
