Synthesis and SAR study of novel Sarsasapogenin (cas 126-19-2) derivatives as potent neuroprotective agents and NO production inhibitors

Add time:09/10/2019    Source:sciencedirect.com

Sarsasapogenin (cas 126-19-2), isolated from rhizomes of Anemarrhena asphodeloides, was found to be able to enhance memory. On the basis of the structure of Sarsasapogenin, a series of derivatives were synthesized and evaluated for their neuroprotective activity in PC12 cells and NO production inhibitory activity in RAW264.7 cell lines. The preliminary structure-activity relationship of them indicated that introduction of carbamate groups at the 3-hydroxyl position of sarsasapogenin might improve neuroprotective activity. Some synthesized derivatives such as AA3, AA4, AA9 and AA13 exhibited both notably neuroprotective activity and NO production inhibitory activity.
