Stigmasterol is an orally acitve, immunomodulatory agent with anti-inflammatory and neuroprotective effect, as well as able to cross the blood-brain barrier. Stigmasterol activates AMPK, which in turn inhibits NF-κB and NLRP3 signaling pathways, reduces microglia-mediated neuroinflammation, and alleviates cognitive impairment and Alzheimer's disease. Stigmasterol regulates M1/M2 polarization of microglia through the TLR4/ NF-κB pathway, thereby reducing neuropathic pain. Stigmasterol can be used for neurodegenerative diseases, inflammatory diseases, and pain management, among others.

Sitostanol is a saturated sterol found in a variety of plants, including corn, wheat, and rice and reduces cholesterol uptake in rats and rabbits.

DC-cholesterol(3β-[N-(N′,N′-Dimethylaminoethyl)carbamoyl]cholesterol), a lipid, has been investigated in cancer gene therapy and vaccine delivery system.

SCS is an orally active cholesterol biosynthesis agonist that targets NPC2. It activates SREBP2 by competitively binding to NPC2, thereby promoting cholesterol synthesis (EC50 = 50 μM).

Cholesterol is a component of Lipid nanoparticles (LNPs) for RNA delivery.
