  摘要：

  羧酸（例如丙烯酸）向胺的转化是在合成有机化学中仍然具有挑战性的转化。尽管在自然代谢途径中普遍存在相似的部分，但出于这一目的，生物催化途径似乎已被忽略。本文中，我们介绍了一种双酶体系的概念和优化方法，它允许从容易获得的环取代肉桂酸合成β-苯乙胺衍生物。在通过两步方法表征了反应的两个部分之后，优化了允许单罐生物转化的一组条件。可逆的脱氨酶和不可逆的脱羧酶的组合，对串联的氨基酸中间体均具有特异性，

  Hydroxyethylene Sulfones as a New Scaffold To Address Aspartic Proteases:  Design, Synthesis, and Structural Characterization

  摘要：

  Hydroxyethylene sulfones were developed as novel scaffolds against aspartyl proteases. A diastereoselective synthesis has been established to introduce the required side chain decoration with desired stereochemistry. Depending on the substitution of the hydroxyethylene-sulfone core, micro- to submicromolar inhibition of HIV-1 protease is achieved for the S-configuration at P, and R-configuration at the hydroxy-group-bearing backbone atom. This stereochemical preference is consistent with the S,R configuration of amprenavir. The racemic mixture of the most potent derivative (K-i = 80 nM) was separated by chiral HPLC, revealing the S,R,S-enantiomer to be more active (K-i = 45 nM). Docking studies suggested this isomer as the more active one. The subsequently determined crystal structure with HIV-1 protease, cocrystallized from a racemic mixture, exclusively reveals the S,R,S-enantiomer accommodated to the binding pocket. The transition state mimicking hydroxy group of the inhibitor is centered between both catalytic aspartates, while either its carbonyl or sulfonyl group forms H-bonds to the structurally conserved water mediating interactions between ligand and Ile50NH/Ile50NH' of both flaps. Biological testing of the stereoisomeric hydroxyethylene sulfones against cathepsin D and beta-secretase did not reveal significant inhibition. Most likely, the latter proteases require inverted configuration at the hydroxy group.

  α-chymotrypsin-catalysed peptide synthesis via the kinetically controlled approach is greatly improved by the use of activated esters such as the 2,2,2-trifluoroethyl ester as acyl donors instead of the conventional methyl ester in organic solvents such as acetonitrile with low water content. This approach is useful for the incorporation of non-protein amino acids such as halogenophenylalanines into peptides.
