  similarly cytotoxic to their nonbiotinylated parents, which suggests that the target identification should not be influenced by linker or biotin. The developed solid-phase synthetic approach is the first attempt to use solid-phase synthesis to connect active triterpenes to biotin and is applicable as a general procedure for routine conjugation of triterpenes with other molecules of choice.

  为了更好地了解抗肿瘤三萜的作用机理，我们正在开发鉴定其分子靶标的方法。一种有前途的方法是基于定量蛋白质组学与SILAC的组合，并使用通过生物素-链霉亲和素相互作用固定在磁珠上的活性化合物。我们开发了一种简单快速的固相合成技术，可通过连接子将萜烯连接至生物素。从三个不同的缀合位点对桦木酸进行生物素化处理，以用作标准验证工具，因为该三萜的许多分子靶标已为人所知。然后，一组其他四个细胞毒性三萜被生物素化。生物素化的萜烯对其非生物素化的父母具有类似的细胞毒性，这表明目标物的鉴定不应受到接头或生物素的影响。

  A set of 41 glycosidic conjugates of pentacyclic triterpenes was synthesized in order to improve the solubility of highly cytotoxic parent compounds. Their in vitro cytotoxic activity was evaluated in 25 cancer cell lines and 2 noncancer fibroblasts. Fifteen compounds had high cytotoxicity on the T-lymphoblastic leukemia cell line CCRF-CEM and 6 of them were active in multiple cell lines of various histogenic origin and not toxic in fibroblasts. Compound 11a had IC50 of 0.64 μM in CCRF-CEM cells, 0.60 μM in K-562 cells, and 0.37 μM in PC-3 cells; compound 12a had IC50 of 0.64 μM in CCRF-CEM cells and 0.71 μM in SW620 cells; compound 17b had IC50 of 0.86 μM in HCT116 cells and 0.92 μM in PC-3 cells. Compounds 11b and 12b were slightly less active than the previously mentioned derivatives; however, their solubility was significantly better, and therefore they were selected for the in vivo evaluation of the pharmacokinetic profile in mice. In both compounds, the maximum concentration in plasma was achieved very rapidly—the highest level in plasma was found 1 h after administration (22.2, respectively, 6.4 μM). For compound 12b, the resorption was followed with fast elimination, and 12 h after administration, the compound was not detected in plasma. In contrast, compound 11b was eliminated more slowly; it was still present in plasma after 12 h, but its concentration dropped below the detection limit after 24 h. The elimination half-time determined for compound 11b was 2.4 h and for compound 12b just about 1.4 h. These values are reasonable for further drug development.

  为了改善高细胞毒性母体的溶解度，我们合成了41种五环三萜糖苷复合物。在25种癌细胞系和2种非癌成纤维细胞中评估了它们的体外细胞毒性活性。15种化合物对T淋巴细胞白血病细胞系CCRF-CEM具有高细胞毒性，其中6种化合物对多种不同组织来源的细胞系具有活性，且对成纤维细胞无毒。化合物11a在CCRF-CEM细胞中的IC50为0.64μM，在K-562细胞中的IC50为0.60μM，在PC-3细胞中的IC50为0.37μM；化合物12a在CCRF-CEM细胞中的IC50为0.64μM，在SW620细胞中的IC50为0.71μM；化合物17b在HCT116细胞中的IC50为0.86μM，在PC-3细胞中的IC50为0.92μM。化合物11b和12b的活性略低于前面提到的衍生物，但溶解度明显更好，因此被选用于小鼠体内药代动力学评估。两种化合物在血浆中的最大浓度都很快达到——给药后1小时血浆中的浓度最高（分别为22
