We synthesized guggulsterone derivatives using [3+2] click reaction with aryl and alkyl acetylene with relatively high yields. These synthesized derivatives were evaluated for kidney cell protection effects against cisplatin toxicity. cisplatin is known as anticancer agent. However, cisplatin induced severe side effects to kidney cells by increasing oxidative stress. Therefore, cisplatin treatment is generally used for chronic kidney disease model. In this research, we evaluated kidney cell protective effects of gugglusterone derivatives. Among these guggulsterone derivatives, 6g which has hydroxyl group show protection effects. It is known that cellular oxidative stress induces MAPK kinase signal pathway and caspase activation. We therefore investigated if 6g reduces these signal cascades. We further investigate population of live of dead cells after treatment of 6g. These data indicated that inhibition of the mitogen-activated protein kinase/caspase-3 signaling cascade by 6g mediates its protective effects against cytotoxicity in cultured LLC-PK1 kidney cells.
