應用
IWR-1已被用作人类胚胎干细胞（hESCs）、小鼠lewis肺癌（LLC）和Sepia胚胎中Wingless/Integrated（WNT）信号通路的拮抗剂。
生化／生理作用
IWR-1是一种端锚聚合酶抑制剂，其对癌症干细胞样细胞具有细胞毒性。它可抑制 体内 骨肉瘤的进展。IWR-1可与RNA聚合酶II相互作用，对于预启动复合物的形成至关重要。
Wnt/b-连环蛋白（‘经典′）途径维持转录程序，使干细胞保持多能性。Wnt/b-连环蛋白途径超活化会导致疾病分期。IWR-3充当Wnt反应的抑制剂。似乎IWR化合物通过直接相互作用诱导Axin蛋白稳定化，该蛋白是b-连环蛋白破坏复合体（由Apc、Axin、Ck1和Gsk3b组成）的一部分。
