PACMA 31 是一种不可逆的蛋白二硫化物异构酶 (PDI) 抑制剂，IC50 为 10μM，PACMA 31 与 PDI 的活性部位半胱氨酸形成共价键。PACMA 31 具有肿瘤靶向性，能显著抑制卵巢肿瘤生长，对正常组织无毒性。PACMA 31 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)。 PACMA 31 is an irreversible, protein disulfide isomerase (PDI) inhibitor with an IC50 of 10 μM. PACMA 31 forms a covalent bond with the active site cysteines of PDI. PACMA 31 shows tumor targeting ability and significantly suppresses ovarian tumor growth without causing toxicity to normal tissues. PACMA 31 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
