Descriptions:
Cycloastragenol(CAG), a triterpene aglycone derived from Radix astragali , can suppress the accumulation of cytoplasmic lipid droplet in 3T3-L1 adipocytes.[1]
Two Chinese herb-derived small molecule telomerase activators, astragaloside IV (AG-IV) and cycloastragenol, have recently been shown to improve the proliferative response of CD8+ T lymphocytes from HIV-infected patients by upregulating telomerase activity, they also may exert their cellular effects through the activation of the Src/MEK/ERK pathway.[2]
Cycloastragenol is the aglycone derivative of astragaloside IV which has recently been demonstrated to activate telomerase and represents a potential drug candidate for the treatment of degenerative diseases, it is efficiently absorbed through intestinal epithelium; it moderately increases telomerase activity and proliferative capacity of both CD4 and CD8 T cells. [3,4]
Cycloastragenol and astragaloside IV suppress ROS-associated ER stress and then inhibited TXNIP/NLRP3 inflammasome activation with regulation of AMPK activity, and thereby ameliorated endothelial dysfunction by inhibiting inflammation and reducing cell apoptosis, they are equally effective in regulation of endothelial homeostasis.[5]
Cycloastragenol can remarkably inhibit CYP3A4 and activate CYP2E1 in rats.[6]
Cycloastragenol has been shown to extend T cell proliferation by increasing telomarase activity showing that it may also help delay the onset of cellular aging ; it is an extraordinary wound healing agent; it inhibits the apoptosis of PC12 induced by 6-OHDA, may be as potential neuroprotective agents in the treatment of Parkinson's disease.
