Various plant triterpenes
have been reported to induce cell cycle arrest including the pentacyclic triterpenes
and polysaccharides from the mushrooms reduce the oxidative impact of destructive proteins such as Abeta, the chief trigger of Alzheimer's disease, (16) and they protect brain cells from the inflammation known to cause Parkinson's disease.
In the case of these products, triterpene
content ranged from undetectable to 7.
Highly oxidized metabolites are often found particularly among the tetracyclic triterpenes
For example, Tego Arjuna S is a standardized plant extract of pentacyclic triterpenes
from Arjuna tree bark.
from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7.
Selective cholinesterase inhibition by lanostane triterpenes
from fruiting bodies of Ganoderma lucidum.
Inhibitory effect of taraxastane-type triterpenes
on tumor promotion by 12-O-tetradecanoylphorbol-13-acetate in two-stage carcinogenesis in mouse skin.
Chemical studies have revealed the presence of alkaloids, quinovic acid, glycosides, polyhydroxylated triterpenes
, flavonoids and catechins in cat's claw, with some compounds showing a potentiation of phagocytosis by white blood cells.
Other medicinally active compounds in mushrooms are glycoproteins, ergosterols, triterpenes
They took 200 mg of a standardized extract with 16 percent triterpenes
three times a day.
Stereospecific construction of complex polycyclic structures such as steroids and triterpenes
via macrocyclic Diels-Alder reactions were discussed by Pierre Deslongchamps, FCIC.
