Application

HI-TOPK-032 has been used as a PDZ binding-kinase (PBK) inhibitor.

Biochem/physiol Actions

HI-TOPK-032 belongs to the class of ATP-competitive inhibitors. It can also be used as a potent therapeutic for colorectal cancer.
HI-TOPK-032 is a specific TOPK (T-LAK cell–originated protein kinase) inhibitor both in vitro and in vivo. HI-TOPK-032 suppressed tumor growth in a colon cancer xenograft model.

The serine-threonine mitogen-activated protein kinase kinase family member T-LAK cell-originated protein kinase (TOPK/PBK) is heavily involved in tumor development, cancer growth, apoptosis, and inflammation. Despite the identification of TOPK as a promising novel therapeutic target, no inhibitor of TOPK has

PDZ binding-kinase (PBK) (also named T-lymphokine-activated killer cell-originated protein kinase (TOPK)), a serine/threonine kinase, is tightly controlled in normal tissues but elevated in many tumors, and functions in tumorigenesis and metastasis. However, the signaling that regulates expression of PBK in
