  3. FKA-9i

FKA-9i is an orally active anticancer agent. FKA-9i directly binds to and promotes the degradation of oncoproteins LRPPRC (kd: 7.387 μM), YBX1 (kd: 16.52 μM) and RPN1 (kd: 26.82 μM). FKA-9i inhibits the MAPK signaling pathway and mitochondrial oxidative phosphorylation. FKA-9i also induces cancer cell cycle arrest, apoptosis, mitochondrial dysfunction and ROS accumulation. FKA-9i can be used in the research of tumors such as gastric cancer.

FKA-9i can be used in the research of tumors such as gastric cancer[1].

Bcl-2

 

In Vitro

FKA-9i (0-72 h) inhibits the proliferation of HGC27, KYSE70, KYSE450, HCT116 and A549 cancer cells, with IC50 values of 1.49, 3.15, 2.25, 3.53 and 4.48 μM, respectively[1].
FKA-9i (0-8 μM; 0-48 h) inhibits tumor cell proliferation, and induces cell cycle arrest and apoptosis[1].
FKA-9i (0-8 μM; 0-48 h) reduces the stability of LRPPRC, YBX1 and RPN1 proteins in HGC27 cells and promotes their degradation[1].
FKA-9i (48 h) inhibits the expression of genes related to the MAPK signaling pathway and suppresses the MAPK cascade in HGC27 cells[1].
FKA-9i (4-8 μM; 48 h) dose-dependently increases intracellular ROS levels in HGC27 and HCT116 cells[1].

In Vivo

FKA-9i (2.5-5 mg/kg; oral gavage; 31 days) exhibits anti-tumor activity in the HGC27 CDX mouse model[1].
FKA-9i (100-200 mg/kg; oral gavage; 10 days) shows no obvious acute organ toxicity in C57BL/6 mice[1].

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.
