Pristimerin
Pristimerin is a carboxylic ester. Pristimerin is a quinone methide triterpenoid researched for its anti-cancer potential. Pristimerin is a natural product found in Reissantia buchananii, Crossopetalum gaumeri, and other organisms with data available. Pristimerin is a potent and reversible monoacylglycerol lipase (MGL) inhibitor with an IC50 of 93 nM. Pristimerin is a potent and reversible monoacylglycerol lipase (MGL) inhibitor with an IC50 of 93 nM.

Betulin
Betulin is found in black elderberry. Betulin is a constituent of Corylus avellana (filbert) and Vicia faba. Betulin (lup-20(29)-ene-3 ,28-diol) is an abundant naturally occurring triterpene. It is commonly isolated from the bark of birch trees and forms up to 30\\\\\% of the dry weight of the extractive. The purpose of the compound in the bark is not known. It can be converted to betulinic acid (the alcohol group replaced by a carboxylic acid group), which is biologically more active than betulin itself. Chemically, betulin is a triterpenoid of lupane structure. It has a pentacyclic ring structure, and hydroxyl groups in positions C3 and C28 Betulin is a pentacyclic triterpenoid that is lupane having a double bond at position 20(29) as well as 3beta-hydroxy and 28-hydroxymethyl substituents. It has a role as a metabolite, an antiviral agent, an analgesic, an anti-inflammatory agent and an antineoplastic agent. It is a pentacyclic triterpenoid and a diol. It derives from a hydride of a lupane. Betulin is a natural product found in Diospyros morrisiana, Euonymus carnosus, and other organisms with data available. A pentacyclic triterpenoid that is lupane having a double bond at position 20(29) as well as 3beta-hydroxy and 28-hydroxymethyl substituents. Constituent of Corylus avellana (filbert) and Vicia faba Betulin (Trochol), is a sterol regulatory element-binding protein (SREBP) inhibitor with an IC50 of 14.5 μM in K562 cell line. Betulin (Trochol), is a sterol regulatory element-binding protein (SREBP) inhibitor with an IC50 of 14.5 μM in K562 cell line.

Celastrol
Celastrol, a plant-derived triterpene, has antioxidant and anti-inflammatory activity that may prevent neuronal degeneration in Alzheimers disease (AD). In the brains of patients with AD signs of neuronal degeneration are accompanied by markers of microglial activation, inflammation, and oxidant damage. The presence of nitrotyrosine in the cell bodies of neurons in AD suggests that peroxynitrite contributes to the pathogenesis of the disease. In low nanomolar concentrations celastrol was found to suppress the production by human monocytes and macrophages of the pro-inflammatory cytokines TNF-alpha and IL-1beta. Celastrol also decreased the induced expression of class II MHC molecules by microglia. In macrophage lineage cells and endothelial cells celastrol decreased induced but not constitutive NO production. Celastrol suppresses adjuvant arthritis in the rat, demonstrating in vivo anti-inflammatory activity. Low doses of celastrol administered to rats significantly improved their performance in memory, learning and psychomotor activity tests. The potent antioxidant and anti-inflammatory activities of celastrol, and its effects on cognitive functions, suggest that the drug may be useful to treat neurodegenerative diseases accompanied by inflammation, such as AD.
