BI-4464 是一种高选择性的 ATP 竞争性 PTK2/FAK 抑制剂，IC50=17 nM。它可用于PROTAC 降解剂的 PTK2 配体。

BI-3663 is a highly selective PTK2/FAK PROTAC that utilizes cereblon ligands to hijack E3 ligases for PTK2 degradation, with an IC50 of 18 nM. It is composed of BI-4464 linked to Pomalidomide with a linker[1]. Anti-cancer.

Tos-PEG4-t-butyl ester (Tos-PEG4-Boc) is a PROTAC linker characterized by its PEG composition. This compound plays a crucial role in the synthesis of a range of PROTACs, including BI-3663, a highly selective PTK2/FAK PROTAC. It employs cereblon ligands to target E3 ligases for the degradation of PTK2, exhibiting potent inhibitory activity with an IC50 of 18 nM[1].
