An efficient synthesis of aryl substituted cyclic sulfonimidamides designed as chiral nonplanar heterocyclic carboxylic acid bioisosteres is described. The cyclic sulfonimidamide ring system could be prepared in two steps from a trifluoroacetyl protected sulfinamide and methylester protected amino acids. By varying the amino acid, a range of different C-3 substituted sulfonimidamides could be prepared
描述了设计为手性非平面杂环羧酸生物电子等排体的芳基取代环状磺酰亚胺酰胺的有效合成。环状磺酰亚胺环系统可以由三氟乙酰基保护的亚磺酰胺和甲基酯保护的氨基酸分两步制备。通过改变氨基酸,可以制备一系列不同的 C-3 取代的磺酰亚胺酰胺。可以使用标准的交叉偶联反应在芳环中进一步衍生化合物,以优异的产率产生高度取代的环状磺酰亚胺酰胺。检查了最终化合物的物理化学性质,并将其与相应的羧酸和四唑衍生物的物理化学性质进行了比较。独特的非平面形状与相对较强的酸度 (p K a 5-6) 以及修改化学结构以微调理化性质的便利性表明,这种杂环可以成为可用羧酸等排体范围的有价值的补充。

The present invention is directed to compounds that are inhibitors of cysteine proteases, in particular, cathepsins B, K, L, F, and S and are therefore useful in treating diseases mediated by these proteases. The present invention is also directed to pharmaceutical compositions comprising these compounds and processes for preparing them. The present invention is also directed to the use of these inhibitors in combination with a therapy that causes a deleterious immune response in patients receiving the therapy.
