Disclosed are polypeptide compounds containing at least one residue comprising a cyclically-constrained &ggr;-amino acid residue. The compounds have the formula
1
where A is a hydrogen, hydroxy, amino- or carboxy-protecting group, Y is a single bond or a prolyl-containing linking group, and X and Y are &ggr;-amino acid residues, provided that one of X or Y is a conformationally-restrained &ggr;-amino acid residue, and “a,” “c,” and “d” are positive integers. The compounds find use as non-enzymatically degradable probes to mimic protein behavior in solution.
本发明涉及聚肽化合物,其中至少包含一个含有环状约束的&ggr;-氨基酸残基。该化合物的化学式为1,其中A是氢、羟基、氨基或羧基保护基团,Y是单键或含有脯氨酰基的连接基团,X和Y是&ggr;-氨基酸残基,但其中一个是构象受限的&ggr;-氨基酸残基,“a”、“c”和“d”是正整数。该化合物可用作非酶降解的探针,模拟溶液中蛋白质的行为。
