  Seven New and Two Known Lipopeptides as well as Five Known Polyketides: The Activated Production of Silent Metabolites in a Marine-Derived Fungus by Chemical Mutagenesis Strategy Using Diethyl Sulphate

  摘要：

  AD-2-1 是一种抗肿瘤真菌突变体，它是通过硫酸二乙酯诱变海洋源青霉菌 G59 获得的。在使用 K562 细胞进行的 MTT 试验中，G59 菌株原本不产生任何具有抗肿瘤活性的代谢物。在 MTT 试验和 TLC 分析的指导下，通过与对照 G59 提取物的直接比较，对新产生的代谢物进行了追踪，从突变体 AD-2-1 的提取物中分离出了七种新的（1-7）和两种已知的（8-9）脂肽，以及五种已知的多酮类化合物 10-14。通过光谱和化学证据确定了七种新化合物的结构及其绝对构型，并将其命名为青霉酰胺 A-G（1-7）。七个已知化合物被鉴定为fellutamide B (8)、fellutamide C (9)、1′-O-methylaverantin (10)、averantin (11)、averufin (12)、nidurufin (13) 和 sterigmatocystin (14)。在 MTT 试验中，1-14 对几种人类癌细胞株有不同程度的抑制作用。所有生物测定和高效液相色谱-光电二极管阵列检测器（PDAD）-紫外和高效液相色谱-电子喷雾电离（ESI）-质谱分析表明，突变体 AD-2-1 中 1-14 的产生是由原始 G59 真菌菌株中沉默代谢物的活化产生引起的。本研究结果为利用硫酸二乙酯诱变的化学诱变策略通过激活真菌分离物中的沉默代谢物来发现新化合物的有效性提供了更多实例。

  用新的二肽基腈抑制剂作为锥虫杀虫剂定位半胱氨酸蛋白酶的S1和S1'亚位点。

  摘要：

  半胱氨酸蛋白酶Cruzipain被认为是治疗南美锥虫病的有效治疗靶标。设计，合成了一系列26种新化合物，并针对重组Cruzain（Cz）进行了测试，以绘制其S1 / S1´子位图。在一组四个人类半胱氨酸蛋白酶（CatB，CatK，CatL，CatS）和墨西哥利什曼原虫CPB（一组可能是治疗皮肤利什曼病的潜在靶标）上对同一系列进行了评估。合成的化合物是基于P1（十个），P2（六个）和P3（四个不同的结构单元）中不同部分最有希望的组合而设计的二肽基腈。八个化合物的Cz的Ki小于20.0 nM，而三个化合物的LmCPB符合这些标准。三种抑制剂的EC50值为ca。4.0微米 因此，根据其抗胰锥作用，与苯硝唑相当。我们的作图方法和各自的结构活性关系为治疗相关的半胱氨酸蛋白酶的特定配体-靶标相互作用提供了见识。
