YIGSR peptidomimetics and methods for making and using the same are provided. The subject YIGSR peptidomimetics are non-peptidic, biodegradation-resistant molecules that mimic the pentapeptide tyrosine-isoleucine-glycine-serine-arginine (YIGSR) binding site for the 67 kiloDalton (kDa) laminin binding protein (LBP). The subject peptidomimetics include a rigid or substantially rigid non-peptidic scaffold that effectively presents or positions a tyrosine or tyrosine-like group, an isoleucine or isoleucine-like group, a serine or serine-like group, and an arginine or arginine-like group in substantially the same manner as occurs in the YIGSR peptide itself. The subject peptidomimetics find use in a variety of different applications, including diagnostic and therapeutic applications.
提供了 YIGSR 拟肽物及其制造和使用方法。所述 YIGSR 拟肽物是非肽、抗生物降解分子,可模拟 67 千道尔顿(kDa)层粘连蛋白(LBP)的五肽酪氨酸-异亮氨酸-甘氨酸-丝氨酸-精氨酸(YIGSR)结合位点。这种多肽模拟物包括一个刚性或基本刚性的非肽支架,它以与 YIGSR 肽本身基本相同的方式有效地呈现或定位酪氨酸或酪氨酸样基团、异亮氨酸或异亮氨酸样基团、丝氨酸或丝氨酸样基团以及精氨酸或精氨酸样基团。这种多肽模拟物可用于各种不同的应用,包括诊断和治疗应用。
