  Efficient Syntheses of a Series of Trehalose Dimycolate (TDM)/Trehalose Dicorynomycolate (TDCM) Analogues and Their Interleukin-6 Level Enhancement Activity in Mice Sera

  摘要：

  We found an IL-6 level-enhancing compound during our synthetic study of trehalose-6,6'-dimycolate (1, TDM, formerly called cord factor) analogues. TDM is a glycolipid distributed in the cell wall of Mycobacterium tuberculosis and shows significant antitumor activity based on an immunoadjuvant activity. However, due to its significant toxicity, TDM is not yet applicable for practical use. In 1993, Datta and Takayama reported the purification of trehalose-6,6'-dicorynomycolate (2c, TDCM) from Corynebacterium spp. We have previously reported the synthesis of four diastereomeric TDCMs and showed that the synthetic (2R,3R,2'R,3'R)-TDCM (2c, hereafter abbreviated RRRR-TDCM-C-14) is identical to natural TDCM; we also demonstrated that 2c and SSSS-TDCM-C-14 (3c) showed significant antitumor activity as well as inhibitory activity in experimental lung metastasis based on the immunoadjuvant activity. Furthermore, we found that the significant lethal toxicity in mice by TDM (1) was no longer observed with the shorter-chain analogues of TDCMs. Therefore, we have elucidated that the 2,3-antistereochemistry (RR or SS) of the fatty acid residue is promising for biological activities. The chain length of the fatty acid residue should also be important for the biological activity, and thus, we designed a general synthetic procedure for trehalose diesters with 2,3-antistereochemistry and a series of chain lengths by using Noyori's asymmetric reduction of beta,beta-ketoesters followed by antiselective alkylation according to Frater to give beta,beta-hydroxy alcohols as the key steps. Thus, we prepared trehalose diesters (TDCM) 2a-d, 3a-d, and 4a-d as well as monoesters (TMCM) 5a-d and 6a-d. Immunological activities of TDCMs and TMCMs were evaluated by determining IL-6 level enhancement in mouse serum, and we found that RRRR-TDCM-C-14 (2c) and RRSS-TDCM-C-14 (4c) showed significant IL-6 level enhancement activities.

  A number of novel beta-ketoesters were prepared by regioselective alkylation reactions of simple beta-ketoester dianions. The cyclization of the dianions of these 1,3-dicarbonyl derivatives with 1-bromo-2-chloroethane afforded a variety of 2-alkylidenetetrahydrofurans with very good regioselectivity and E/Z-diastereoselectivity. These products were deprotonated to give novel ambident carbanions. The

  product by an aromatic ring. This design element is general and the synthesis is straightforward, providing ready access to libraries of polyfunctional fluorophores with long Stokes shifts based on the epicocconone core. Our structural modifications resulted in analogues with increased photostability and quantum yields compared with the natural product. Staining proteomic gels with these new analogues

  Epicocconone 是一种天然的潜在荧光团，由于其较大的斯托克斯位移和在未结合状态下缺乏荧光而广泛用于生物技术。然而，epicocconone 的低光稳定性和量子产率限制了其更广泛的应用，并且在没有全合成的情况下，这种限制一直是一个长期存在的问题。在这里，我们报告了一种合成 Epiocconone 类似物的一般策略，该策略依赖于 2-碘氧基苯甲酸介导的脱芳构化和用芳香环替换天然产物的三烯尾。这种设计元素是通用的，合成很简单，可以随时访问基于epicocconone 核心的具有长斯托克斯位移的多功能荧光团库。与天然产物相比，我们的结构修改导致类似物具有更高的光稳定性和量子产率。用这些新类似物对蛋白质组凝胶染色显示检测限显着降低，检测到的低丰度蛋白质数量增加了 30%。这些epiccoconone 类似物将大大提高蛋白质组大海捞针中生物标志物针的发现率。

• Titanium(III)-mediated synthesis of a 1,2,3-tricarbonyl moiety from an .alpha.-oximido-.beta.-keto ester: application to the synthesis of the carbacephem nucleus

  日期：1992.6

  A general procedure for the conversion of alpha-oximido-beta-keto esters into vicinal tricarbonyl moieties by TiCl3 in aqueous, buffered (pH 5) conditions with acetone cosolvent was demonstrated. As applied to N-hydroxy beta-lactam 17, which contained an alpha-oximido-beta-keto ester side chain, these combined reductive and hydrolytic conditions effected simultaneous tricarbonyl formation and beta-lactam N-O bond reduction. Vicinal tricarbonyl-containing N-unsubstituted beta-lactam 18 was a direct precursor to semifunctionalized carbacephem 1.
