摘要

Stimulation of lysosomal activity and ROS formation in mouse peritoneal macrophages by five triterpene glycosides, typicosides A_1 (1), A_2 (2), B_1 (3), C_1 (4) and C_2 (5) has been studied and compared with their cytotoxic activities. Glycosides 1-3 possess moderate activities, but the most cytotoxic glycoside 5 is not active. Typicoside C_1 (4), with low toxicity, was proved to be the most active concerning stimulation of ROS formation. This is the first example of a triterpene glycoside from sea cucumbers with low cytotoxicity, but which demonstrates a strong immunostimulatory effect on mouse peritoneal macrophages in vitro.
