    摘要:
    本文描述的是通过涉及从简单氨基酸丝氨酸快速构建天然产物的吡咯烷酮核心的策略来全合成盐孢菌酰胺。该合成成功的关键是通过单个羟醛环化步骤在吡咯烷酮核心上立体选择性安装三个连续的立构中心,该步骤采用了“手性记忆”和动态动力学解析的原理。

    A composition for chemically treating a target condition, existing at a microenvironment localized within an environment, with an active compound, the composition comprising precursor components which can conjugate covalently to form the active compound in situ, and for which the covalent conjugation is more favourable at the microenvironment of the target condition than in the surrounding environment. Disclosed examples include biologically-active compounds which are preferentially formed in the microenvironment of tumour cells.

  • Essential Role of the Donor Acyl Carrier Protein in Stereoselective Chain Translocation to a Fully Reducing Module of the Nanchangmycin Polyketide Synthase
    作者:Xun Guo、Tiangang Liu、Zixin Deng、David E. Cane
    DOI:10.1021/bi201768v
    日期:2012.1.31
    Incubation of recombinant module 2 of the polyether nanchangmycin synthase (NANS), carrying an appended thioesterase domain, with the ACP-bound substrate (2RS)-2-methyl-3-ketobutyryl-NANS_ACP1 (2-ACP1) and methylmalonyl-CoA in the presence of NADPH gave diastereomerically pure (25,4R)-2,4-dimethyl-5-ketohexanoic acid (4a). These results contrast with the previously reported weak discrimination by NANS module 2+TE between the enantiomers of the corresponding N-acetylcysteamine-conjugated substrate analogue (+/-)-2-methyl-3-ketobutyryl-SNAC (2-SNAC), which resulted in formation of a 5:3 mixture of 4a and its (2S,4S)-diastereomer 4h. Incubation of NANS module 2+TE with 2-ACP1 in the absence of NADPH gave unreduced 3,5,6-trimethyl-4-hydroxypyrone (3) with a K-cat of 4.4 +/- 0.9 min(-1) and a k(cat)/K-m of 67 min(-1) mM(-1), corresponding to a similar to 2300-fold increase compared to the k(cat)/K-m for the diffusive substrate 2-SNAC. Covalent tethering of the 2-methyl-3-ketobutyryl thioester substrate to the NANS ACP1 domain derived from the natural upstream PKS module of the nanchangmycin synthase significantly enhanced both the stereospecificity and the kinetic efficiency of the sequential polyketide chain translocation and condensation reactions catalyzed by the ketosynthase domain of NANS module 2.
