    以胆固醇、胆固醇和弗里德醇为苷元合成皂苷
    摘要:
    用于合成支链 Xylβ(13)[Galβ(12)]-Glc 和 Xylβ(13)[Galβ(12)]-GlcUA 三糖 β-连接到胆固醇、胆固醇和弗里德醇的 3-O 的程序,分别,被开发。为此,研究了胆固醇与葡萄糖基供体的 β 选择性葡萄糖基化,从而选择性地获得 2-O、3-O 和 6-O。这样获得具有2-O-酰基、3-O-苄基和4,6-O-亚苄基或还有苄基保护的中间体10和21。去除 2-O-酰基,然后半乳糖基化得到 β(12)-连接的二糖中间体 14 和 23。使用 O-亚苄基和/或 O-苄基保护基团的标准操作可以选择性地访问 3-O葡糖基残基,从而为木糖基供体提供β-连接到胆固醇残基(化合物18)的三糖作为决定性中间体。通过将 Xylβ(13)Glc 残基连接到胆固醇,然后半乳糖基化,可以开发该化合物的替代方法。18 的总脱保护或硫酸基团和十二烷基氨基甲酰基残基在 6a-O 处的区域选择性引入分别提供了皂苷

    Synthesis of XylβCer, Galβ1−4XylβCer, NeuAcα2−3Galβ1−4XylβCer and the Corresponding Lactone and Lactam Trisaccharides
    摘要:
    2-(Trimethylsilyl)ethyl 2-O-benzoyl- and 2,3-di-O-acetyl-beta-D-xylopyranosides (12 and 14) were synthesized in high yields and subjected to glycosylation with various glycosyl donors. Galactosylation of 12 gave the xylose analogue of TMSEt lactoside (3), which was transformed into the glycosyl acceptor 19. Sialylation then gave the xylose analogue of G(M3) trisaccharide (5). The TMSEt glycosides 10, 25, and 32 were transformed into the corresponding trichloroacetimidates, which were used for glycosylation of an azidosphingosine derivative. The resulting sphingosyl glycosides were transformed into the title ceramides. Treatment of NeuAc alpha 2-3Gal beta 1-4Xyl beta Cer (5) with acetic acid gave the corresponding l''-2'-lactone 7. Glycosylation of 12 or 14 with a G(M4)-lactam donor (40) gave the xylose analogue of G(M3)-lactam (42). There was a 3-fold increase in the formation of GAG chains in the presence of 0.5 mu M Xyl beta Cer (2) in the medium.

    report a novel strategy for the design and construction of natural and natural product-like libraries based on the principle of privileged structures, a term originally introduced to describe structural motifs capable of interacting with a variety of unrelated molecular targets. The identification of such privileged structures in natural products is discussed, and subsequently the 2,2-dimethylbenzopyran
    在此,我们报告了一种基于特权结构原理设计和构建天然天然产物类库的新策略,该术语最初用于描述能够与各种不相关的分子靶标相互作用的结构基序。讨论了天然产物中此类特权结构的鉴定,随后选择 2,2-二甲基喃部分作为通过该策略构建类天然产物库的初始模板。最初,采用独特的环加载策略开发了喃基序的新型固相合成,该策略依赖于使用新的聚苯乙烯溴化硒树脂。一旦确定了这些喃的加载、加工和裂解,

    inhibition of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). These coumarins were very weak or ineffective as inhibitors of the housekeeping, offtarget isoforms CA I and II, but some of them inhibited tumor-associated CA IX and XII in the low nanomolar range. They also significantly inhibited the growth of primary tumors by the highly aggressive 4T1 syngeneic mouse mammary tumor cells at 30 mg/kg, constituting
    合成了一系列结合了各种糖基部分的7-取代香豆素,并研究了其对碳酸酐酶的抑制作用(CA,EC 4.2.1.1)。这些香豆素作为管家抑制剂靶亚型CA I和II非常弱或无效,但其中一些在低纳摩尔范围内抑制与肿瘤相关的CA IX和XII。它们还以30 mg / kg的高侵袭性4T1同系小鼠乳腺肿瘤细胞显着抑制了原发性肿瘤的生长,构成了开发概念上新颖的抗癌药物的有趣候选物。由于CA IX在低性肿瘤中过表达,并且在正常组织中的表达非常有限,因此此类化合物可用于治疗对经典化学疗法和放射疗法无反应的癌症。

The results indicated that their HLB number decreased with increase of alkyl chain, the water solubility improved since the hydrophilic oxyethene (─OCH2CH2─) fragment was introduced. The dissolution process was entropy driven at 25–45 °C for alkyl chain length n = 6–10. Octyloxyethyl β‐d‐xylopyranoside had the best foaming ability
