N-(PEG1-OH)-N-Boc-PEG2-propargyl 是一种 PROTAC linker，属于 PEG 类。可用于合成 PROTAC 分子。N-(PEG1-OH)-N-Boc-PEG2-propargyl 是一种点击化学试剂。它含有 Alkyne 基团，可以和含有 Azide 基团的分子发生铜催化的叠氮-炔环加成反应 (CuAAc)。 N-(PEG1-OH)-N-Boc-PEG2-propargyl is a branched PEG derivative with a terminal hydroxy group, propargyl group, and a Boc protected amino group. The hydroxy group enables further derivatization or replacement with other reactive functional groups. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected by acidic conditions.
