The novel α-amino acid BpAib, a partially conformationally restricted analogue of the currently extensively used 3-(4-benzoylphenyl)alanine (Bpa) photoaffinity label, was synthesized, optically resolved, fully characterized, and appropriately derivatized. An intermolecular photocrosslinking experiment highlighted its regioselective reactivity towards the S-methyl side-chain group of a Met-based dipeptide, which is closely comparable to that of Bpa.

α-氨基酸BpAib,这是当前广泛使用的光亲和标记物3-(4-苯甲酰苯基)丙
氨酸(Bpa)的部分构象限制类似物,经过光学分离、完全表征并适当地衍生化。一项分子间光交联实验突出了其对Met基二肽中S-甲基侧链基团的区域选择性反应性,与Bpa非常相似。
