我们开发了一系列具有不同P3基团的氮杂二肽腈。三芳基间苯基衍生物(化合物13)不仅是组织蛋白酶K的有效抑制剂(K i = 0.0031 nM),而且对组织蛋白酶B和S都具有很高的选择性(约1000倍)。在该系列上进行的蛋白质-配体对接研究提供了可能的解释,为什么化合物13可能比其他化合物更有效,尤其是同一系列中的化合物12。

A series of N-(4-methoxy, 4-fluoro, 4-trifluoromethyl and 4-nitrobenzoyl)-L-amino acids was synthesized and their inhibitoryactivity towards bovine lens aldosereductase (ALR2) was tested.

An enantioselective C-H iodination reaction using a mono-N-benzoyl-protected amino acid has been developed for the synthesis of chiral diarylmethylamines. The reaction uses iodine as the sole oxidant and proceeds at ambient temperature and under air.
Microsphere Formation in a Series of Derivatized .alpha.-Amino Acids: Properties, Molecular Modeling, and Oral Delivery of Salmon Calcitonin
A series of benzoylated and phenylsulfonylated amino acids are novel, low molecular weight, self-assembling molecules. At low pH, these compounds form microspheres that dissolve readily under neutral conditions. In a given synthetic series, those molecules with low aqueous solubility formed microspheres more readily than did the molecules possessing high water solubility, suggesting that the hydrophobicity of these compounds contributes to the ability to form microspheres. In addition, molecular modeling studies on selected compounds have shown that microsphere formation may depend also on various aromatic ring and dipole-dipole interactions, which could effect the extent and types of favorable stacking conformations between molecules. The microspheres prepared from these compounds have been used to effect the oral delivery of salmon calcitonin, a model protein drug, in both rodents and primates.

series of azadipeptide nitriles with different P3 groups. A triaryl meta-phenyl derivative, compound 13, was not only a potentinhibitor for cathepsin K (Ki = 0.0031 nM), but also highly selective over both cathepsins B and S (∼1000-fold). A protein–ligand docking study performed on the series provided a possible explanation why compound 13 could be significantly more potent than the others, especially
