  Synthesis and antiamnesic activity of a series of N-acylprolyl-containing dipeptides

  摘要：

  Esters and amides of a series of N-acylprolyl-containing dipeptides were synthesized. It was established that these substances possess the ability to prevent memory decline evoked by maximal electroshock (MES) in a passive avoidance step-through paradigm. These N-acylprolyl-containing dipeptides were designed as analogues of pyroglutamyl-containing dipeptides, which we previously demonstrated to be highly active nootropics. Among the structure-activity relationships explored were the effect of N-acyl-substitution size, C-terminal substitution and the nature of the second amino acid. The optimal N-acyl moiety was the N-phenyl-acetyl group, while the optimal C-terminal substitution-esters were those derived from low alkyl alcohols. The optimal second amino acids were Asp, Glu or their fragments, Gly, beta-Ala, GABA. Compound 1 (N-phenylacetylprolylglycine ethyl ester) was selected for further evaluation in impaired cognitive functions. It was supposed that esters and unsubstituted amides of N-acylprolylglycines are prodrugs,which convert to the bioactive cyclo-(Pro-Gly) by virtue of enzymatic or chemical lability within the body.

  通过协同作用增强疏水相互作用和氢键强度：凝血酶抑制剂同类的合成，建模和分子动力学模拟。

  摘要：

  通过计算方法准确预测配体与其受体的结合亲和力是基于结构的药物设计的主要挑战之一。这些预测中潜在的重大错误之一是非共价相互作用的配体结合亲和力贡献是可加的共同假设。本文中，我们介绍了从两个单独的凝血酶抑制剂系列中获得的数据，这些凝血酶抑制剂的大小不断增加，并结合在S3口袋中，并带有或不带有与Gly 216氢键键合的相邻胺的疏水侧链。一米的S1'袋-氯苄基部分结合，并且所述第二具有苄脒部分。当相邻氢键存在时，增强的每的结合亲和力2与缺少该氢键的抑制剂相比，S3袋中疏水接触表面的表面张力分别提高了75％和59％。每结合亲和力的这种改进2演示了疏水相互作用和氢键间的协同性。

  molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyl adenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile

  微生物天然产物的基因组挖掘使化学家不仅能够发现具有新颖骨架的生物活性分子，而且能够识别催化多种化学反应的酶。探索这些生物合成酶的底物混杂性和催化机理有助于开发潜在的生物催化剂。SFAB是一种形成酰基腺苷酸的酶，可在由硫链霉菌产生的二异腈自然产物SF2768的生物合成途径中，对独特的结构单元3-异氰基丁酸进行腺苷酸化。，并且该AMP连接酶被证明可以接受各种短链脂肪酸（SCFA）。在本文中，我们将SFAB重新用于催化那些SCFA与各种胺或硫醇亲核试剂之间的酰胺化或硫酯化反应，从而提供了另一种酶促方法来体外制备相应的酰胺和硫酯。
