英文摘要	Oleanolic acid (OA) and echinocystic acid (EA), two naturally occurring pentacyclic oleanane triterpenes, are gaining increasing attention due to their promising pharmacological activities. Conjugation with amphiphilic alpha(beta)-cyclodextrin (CD) via "click chemistry" can improve their solubility and anti-HCV entry potency. In the present work, four water-soluble beta-CD-pentacyclic triterpene conjugates were designed and synthesized, in which OA and EA was coupled to one of the primary hydroxyl groups of beta-CD via ester and amide bonds. The structures of the conjugates were unambiguously determined by H-1 NMR, C-13 NMR and HRMS or MALDI-TOF-MS. All the conjugates showed lower hydrophobicity (AlogP) than their parent compounds and no significant cytotoxicity was found to HL-60, A549, Hela and Bel-7402 cells at concentrations up to 10 mu mol/L. Further anti-HCV entry activity and mechanism studies are under way in our laboratory. (C) 2018 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
