CKD-712 is an orally active multi-target tetrahydroisoquinoline derivatived and a potent inhibitor of the NF-κB pathway. CKD-712 selectively inhibits MMP-9 with no effect on MMP-2, downregulates the expression of TNF-α, IL-6, cyclin A, cyclin B, CDK-1 and other proteins, and activates the PI3K/Akt signaling pathway. CKD-712 blocks the activation and nuclear translocation of NF-κB, downregulates inflammatory factors and pro-tumor metastatic proteins, and induces G2/M phase arrest in tumor cells and thereby inhibits the invasion of cancer cells. CKD-712 can be used for the research of sepsis, myocardial ischemia-reperfusion injury and non-small cell lung cancer.

Description

CKD-712 is an orally active multi-target tetrahydroisoquinoline derivatived and a potent inhibitor of the NF-κB pathway[2]. CKD-712 selectively inhibits MMP-9 with no effect on MMP-2, downregulates the expression of TNF-α, IL-6, cyclin A, cyclin B, CDK-1 and other proteins, and activates the PI3K/Akt signaling pathway[1][2]. CKD-712 blocks the activation and nuclear translocation of NF-κB, downregulates inflammatory factors and pro-tumor metastatic proteins, and induces G2/M phase arrest in tumor cells and thereby inhibits the invasion of cancer cells[1][2]. CKD-712 can be used for the research of sepsis, myocardial ischemia-reperfusion injury and non-small cell lung cancer[1][2][3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
