    郁金香脂质体转化酶的底物特异性,郁金香中独特的非酯水解性羧酸酯酶:底物醇部分对酶活性的影响。
    摘要:
    6-Tuliposides A(PosA)和B(PosB)是作为主要防御性次要代谢产物积聚在郁金香(Tulipa gesneriana)中的葡萄糖酯。我们先前从郁金香中发现的Pos转换酶(TgTCEs)分别催化PosA和PosB分别转化为抗菌性郁金香脂蛋白A(PaA)和B(PaB)的反应。属于羧酸酯酶家族的TgTCEs特异性催化分子内酯交换反应,但不催化水解。在本报告中,我们合成了具有各种醇基的Pos类似物,并测量了TgTCE活性,并确定了这些类似物的动力学参数,以期探索独特的非酯水解TgTCEs的底物识别机制。已经发现,d-葡萄糖样结构和醇部分中羟基的数目对于TgTCE识别底物很重要。在检测的类似物中,发现通过降低Km值,TgTCE比真实的底物更能特异性地识别PosA和PosB的1,2-二脱氧类似物。本结果将为设计用于TgTCE晶体学分析的简单,稳定的合成底物类似物提供基础。

  • The antibacterial properties of 6-tuliposide B. Synthesis of 6-tuliposide B analogues and structure–activity relationship
    作者:Kengo Shigetomi、Kazuaki Shoji、Shinya Mitsuhashi、Makoto Ubukata

    6-Tuliposide B is a secondary metabolite occurring specifically in tulip anthers. Recently, a potent antibacterial activity of 6-tuliposide B has been reported. However, its molecular target has not yet been established, nor its action mechanism. To shed light on such issues, 6-tuliposide B and tulipalin B analogues were synthesized and a structure-activity relationship (SAR) was examined using a broad panel of bacterial strains. As the results of SAR among a total of 25 compounds, only tulipalin B and the compounds having 3',4'-dihydroxy-2'-methylenebutanoate (DHMB) moieties showed any significant antibacterial activity. Moreover, the 3'R analogues of these compounds displayed essentially the same activities as 6-tuliposide B and the structure of the 3'R-DMBA moiety was the same as that of the proposed active moiety of cnicin. These results suggest that 6-tuliposide B has the same action mechanism as proposed for cnicin and bacteria) MurA is one of the major molecular targets of 6-tuliposide B. (C) 2009 Elsevier Ltd.
