 | Hazard Information | Back Directory |  | [Description] 
 Gracillin is a steroidal saponin that has been found in C. speciosus and has diverse biological activities.1,2,3 It reduces cell growth in a panel of 58 leukemia, non-small cell lung, colon, CNS, prostate, melanoma, ovarian, renal, and breast cancer cell lines (GI50s = 0.58-2.44 μM).1 Gracillin reduces growth of fish Ich parasite (I. multifiliis) theronts (EC50 = 0.53 mg/L) and induces 100 and 92.5% mortality of I. multifiliis protomonts and encysted tomonts, respectively, when used at a concentration of 0.8 mg/L.2 It decreases the number of I. multifiliis-infected goldfish by approximately 75% when used at a concentration of 1 mg/L in tank water. Gracillin (100 mg/kg) reduces ear edema induced by arachidonic acid (Item No. 90010) in mice.3
 |  | [Chemical Properties] 
 White powder, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from the rhizomes of Dioscorea zingiberensis and Dioscorea parviflora.
 |  | [Uses] 
 Gracillin is a steroidal glycoside from the rhizomes of the family Dioscoreaceae with potential anti-proliferative effects.
 |  | [Definition] 
 ChEBI: Gracillin is a triterpenoid.
 |  | [in vivo] 
 
 Gracillin (oral gavage, 10?mg/kg for xenografts and 20?mg/kg for PDX) inhibits tumor growth of xenograft tumors inoculating lung (H1299), prostate (DU145), and colorectum (HCT116) cancer cells, as well as patient-derived xenograft colon and lung tumors[1].
