  摘要：

  The diastereoselective reaction of organometallic compounds (RMgX, R(2)Cd) with in situ generated trifluoromethyl substituted cyclic acyl imines representing homochiral alpha-electrophilic 3,3,3-trifluoroalanine equivalents gives 3-alkyl-3-trifluoromethyl-2,5-diketopiperazines. The corresponding homochiral dipeptide esters are obtained on acidolysis in methanol.

  摘要：

  有人提出将4-氨基环磷酰胺（4-NH2-CPA，7）用作磷酰胺芥末的前药部分。合成了4-NH2-CPA的苯丙氨酸-共轭物的四个非对映异构体，并根据色谱和光谱数据确定了它们的立体化学。所有非对映异构体均在磷酸盐缓冲液中稳定，但只有15-的顺-（4R）-异构体可被α-胰凝乳蛋白酶有效裂解，半衰期为20分钟，比发现的8.9h至> 12h半衰期短得多。对于其他非对映异构体。顺式-（4R）-15蛋白水解产物的LC-MS分析表明，4-NH2-CPA在蛋白水解后释放，并进一步分解为磷酰胺芥末。这些结果表明使用肽缀合的顺式-（4R）-4-NH2-CPA作为潜在的前药在肿瘤组织中进行蛋白水解激活的可行性。

  羧酸生物甾醇的LAT1活性：评估异羟肟酸为底物

  摘要：

  大型中性氨基酸转运蛋白1（LAT1）是一种溶质载体蛋白，主要位于血脑屏障（BBB）中，具有将药物输送到大脑的潜力。作为肿瘤新陈代谢需求增加的一部分，它在癌细胞中也被上调。以前，已经证明氨基酸前药是通过LAT1转运的。与天然氨基酸衍生的羧酸相比，羧酸类生物甾醇可能提供具有改变的物理化学和药代动力学特性的前药，从而使药物的大脑或肿瘤水平更高和/或毒性更低。考察了用四唑，酰基磺酰胺和异羟肟酸（HA）生物等排代物取代苯丙氨酸的羧酸的效果。使用顺式抑制和抑制作用对化合物作为LAT1底物的能力进行了测试反刺激细胞测定。由于HA-Phe具有弱的底物活性，因此通过合成和测试其他LAT1氨基酸底物（即Tyr，Leu，Ile和Met）的HA衍生物，进一步探索了其结构-活性关系（SAR）。通过对HA-Leu和相应的甲酯衍生物进行化合物稳定性实验，评估了由亲本氨基酸引起的反式刺激试验中假阳性的可能性。我们得出的结

  This paper describes the design and synthesis of a new type of aminoacyl-adenylate analogue (aa-AMPN) having an N-acyl phosphoramidate linkage where the oxygen atom of the mixed anhydride bond of aminoacyl-adenylate (aa-AMP) is replaced by an amino group. This new type of aa-AMP analogue is expected to be useful as material for studies on the recognition mechanism of the aminoacylation of tRNA and

  本文介绍了具有N-酰基氨基磷酸酯键的新型氨基酰基-腺苷酸类似物（aa-AMPN）的设计和合成，其中氨基酰基-腺苷酸（aa-AMP）的混合酸酐键的氧原子被氨基。这种新型的aa-AMP类似物有望用作研究tRNA氨基酰化和其他生化反应识别机制的材料。羧酰胺的亚磷酰胺衍生物与核苷衍生物的缩合失败，因为活化的亚磷酰胺衍生物不仅与羟基反应，而且与另一种反应性物质反应。通过5'-O-亚磷酰胺基腺苷衍生物与羧酰胺衍生物的反应研究了另一种方法。选择TBTr和TSE基团分别用于保护氨基酸酰胺的氨基和磷酸基。详细研究表明，使用5-（3,5-二硝基苯基）-1H-四唑作为亚磷酰胺的活化催化剂可在10分钟内迅速缩合，从而得到完全保护的aa-AMPN衍生物。没有发生副反应。通过两步程序对这些产物进行脱保护，得到高产率的aa-AMPN衍生物。还证明由此获得的aa-AMPN在酸性和碱性条件下均是稳定的，例如0.1M HCl（pH

  A one-pot self regulated approach for the synthesis of amides/peptides based on two reduction–oxidation (redox) reactions has been described. The primary and secondary amides/peptides are made by using azidotrimethylsilane and alkyl azides/α-azido acid derivatives respectively as the direct source of amine components.

  Directed hydration of alpha-amino nitriles was achieved under mild conditions using simple carbohydrates as catalysts exploiting temporary intramolecularity. A broadly applicable procedure using both formaldehyde and NaOH as catalysts efficiently hydrated a variety of primary and secondary susbtrates, and allowed the hydration of enantiopure substrates to proceed without racemization.

  α-氨基腈的直接水合反应是在温和的条件下使用简单的碳水化合物作为催化剂利用暂时的分子内作用而实现的。使用甲醛和氢氧化钠作为催化剂的广泛适用的方法有效地水合了各种主要和次要表面活性物，并使对映纯底物的水合得以进行，而不会发生外消旋作用。这项工作还提供了碳水化合物的催化活性的罕见比较，并表明，基于化学演化的简单醛是模仿水合酶功能的有效有机催化剂。对于不稳定的醛，可以观察到最佳的催化效率，而对于难处理的底物，只有简单的碳水化合物（如甲醛和乙醇醛）才是可靠的。
