  Influence of esterification and modification of A-ring in a group of lupane acids on their cytotoxicity

  摘要：

  The aim of this work was to find an optimal ester group for preparation of lupane derivatives connecting high cytotoxicity with good chemical and pharmacological properties. Activities of methyl-, pivaloyloxymethyl-(Pom-), and acetoxymethyl(Acm-) esters were compared with the activity of free acids. Although the methyl- and Pom-esters were generally less active than free acids, some Acm-esters had cytotoxicity similar to or even better than the starting compounds. Cytotoxic activity was measured in five cancer cell lines. (c) 2005 Elsevier Ltd. All rights reserved.

  The present invention relates to betulonic and betulinic acid derivatives and, in particular, to C-28 and C-3 derivatives. The present invention relates to betulonic acid esters, dihydro-betulonic acid esters, PAG-modified betulinic acid derivatives, and PAG-modified dihydro-betulinic acid derivatives. Betulinic acid and derivatives thereof may be bound to a poly(alkylene glycol) (PAG) such as poly(ethylene glycol). Binding may be via a linker, such as a diamine, an amino acid, a peptide, an ester or a carbonate. The compounds of the present invention may be used for the treatment of cancer or a viral infection. The present invention also provides pharmaceutical compositions comprising the compounds of the present invention. The present invention further provides processes for the preparation of the compounds of the present invention, for example, from betulin.

  本发明涉及白桦酸和白桦皮酸衍生物，特别是C-28和C-3衍生物。本发明涉及白桦酸酯、二氢白桦酸酯、PAG修饰的白桦皮酸衍生物和PAG修饰的二氢白桦皮酸衍生物。白桦皮酸及其衍生物可以与聚（烯基氧化物）（PAG）如聚（乙二醇）结合。结合可以通过连接剂，例如二胺、氨基酸、肽、酯或碳酸酯实现。本发明的化合物可用于癌症或病毒感染的治疗。本发明还提供了包含本发明化合物的制药组合物。本发明还提供了制备本发明化合物的方法，例如从白桦中制备。
