    摘要:
    熊果酸(1)和山奈酚(3)是地中海植物夹竹桃(Nerium oleander L.)的两个主要成分。黄曲霉(Aspergillus flavus,ATCC 9170)对(1)进行微生物代谢后,生成了3-氧代熊果酸衍生物——乌索酸(2)。另一方面,布拉克须霉(Cunninghamella blakesleeana,ATCC 8688A)能够将(3)转化为山奈酚3-O-β-D-吡喃葡萄糖苷(4)以及新的天然产物山奈酚4'-磺酸(5)。将山奈酚与拉曼根霉(Mucor ramannianus,ATCC 9268)共培养,分离出一种代谢物,鉴定为山奈酚4'-O-α-L-吡喃鼠李糖苷(6)。在白僵菌(Beauveria bassiana,ATCC 13144)发酵过程中,观察到山奈酚转化为新化合物山奈酚7-O-β-D-4-O-甲基吡喃葡萄糖苷(7)和草棉素8-O-β-D-吡喃葡萄糖苷(8)。测定了分离代谢物的细胞毒性和抗氧化活性。

    Three new compounds, including a pair of chromone derivatives (1–2), and an acetophenone glucoside (3), together with three known compounds (4–6), were isolated from the mangrove endophytic fungus Mycosphaerella sp. L3A1. Their structures were elucidated by HR-ESI-MS analysis and extensive spectroscopic data. The absolute configurations of new compounds were determined using single-crystal X-ray diffraction

    The installation of halogen atoms into aromatic and less activated polyketide substrates by halogenases is a powerful strategy to tune the bioactivity, bioavailability, and reactivity of compounds. In the biosynthetic pathway of totopotensamide A (1), the halogenase TotH was confirmed in vivo to catalyze the C-4 chlorination to form the nonproteinogenic amino acid ClMeDPG. Herein, we report the isolation
    通过卤化酶将卤素原子安装到芳香族和活性较低的聚酮化合物底物中是调节化合物的生物活性、生物利用度和反应性的有力策略。在 totoptensamide A ( 1 ) 的生物合成途径中,卤化酶 TotH 在体内被证实可催化 C-4 氯化形成非蛋白氨基酸 ClMeDPG。在此,我们报告了来自totH灭活菌株的六种新脱氯 totoptensamide (TPM) 同系物 TPM H2–H7 ( 5 – 10 )的分离、结构解析和生物活性评估,以及使用4的 TPM 中聚酮化合物链的拟议绝对构型作为模型化合物由J的组合BCA 和生物信息学分析。化合物5、6、8和9显示出对 A549 、 PANC- 1、Calu3 和 BXPC3 细胞系的细胞毒性,IC 50值范围为 2.3 至 9.7 μM。

  • Deletion of a Histone Acetyltransferase Leads to the Pleiotropic Activation of Natural Products in <i>Metarhizium robertsii</i>
    作者:Aili Fan、Wubin Mi、Zhiguo Liu、Guohong Zeng、Peng Zhang、Youcai Hu、Weiguo Fang、Wen-Bing Yin

    日期:2017.4.7
    Histone deacetylation normally decreases the gene expression in organisms. By genome-wide deletions of epigenetic regulators in entomopathogenic fungus Metarhizium robertsii unexpected activations of orphan secondary metabolite genes have been found upon the disruption of a histone acetyltransferase (HAT) gene Hat1. This led to the characterization of 11 new natural products, including eight isocoumarin derivatives meromusides A-H and two nonribosomal peptides meromutides A and B. Therefore, disruption of HAT represents a new approach to mine chemical diversity from fungi.
