O-propargyl-puromycin（OPP）是嘌呤霉素的炔烃衍生物，用于监测新生蛋白质合成。其通过掺入翻译中多肽链的C-末端而使翻译停止，是一种有效的蛋白质合成抑制剂。
OPP可与新生多肽链缀合而构成共价形式，且可通过铜（I）催化的叠氮化物-炔烃环加成作用被可视化或捕获[1]。因此，OPP通常被认为是细胞和动物中新生蛋白质的成像和鉴定的标记物。已有研究报道，在CHO细胞中，OPP标记可以量化总蛋白质（global protein）的合成。此外，在单细胞水平，OPP标记使总蛋白质的合成率与DNA含量密切相关[2]。在体内研究中发现：注射OPP的小鼠组织与未注射OPP的小鼠组织相比，OPP与新生蛋白质的结合具有特异性 [1]。OPP介导的鉴定（OPP-ID）则是一种当细胞受到刺激和压力时研究细胞如何调节新生蛋白表达的技术，可应用于大多数细胞类型，用途广泛[3]。
