AZ7550 Mesylate 是 AZD9291 的一种活性代谢物，AZ7550 抑制 IGF1R 活性，IC50 为 1.6 μM。

KW-2450 free base is an orally bioavailable inhibitor of insulin-like growth factor 1 receptor (IGF-1R) and insulin receptor (IR) tyrosine kinases with potential antineoplastic activity. IGF-1R/IR inhibitor KW-2450 free base selectively binds to and inhibits the activities of IGF-1R and IR, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell apoptosis. IGF-R1 and IR tyrosine kinases, overexpressed in a variety of human cancers, play significant roles in the stimulation of cellular proliferation, oncogenic transformation, and suppression of apoptosis.

Ganitumab (AMG 479) 是一种重组人1型胰岛素样生长因子受体 (IGF1R) 单克隆抗体。Ganitumab 识别具有亚纳米摩尔亲和力的小鼠 IGF1R (KD=0.22 nM)，并抑制小鼠 IGF1R 与 IGF1 和 IGF2 的相互作用。Ganitumab 可用于癌症研究。
