NF-κB-IN-22
NF-κB-IN-22 is an inhibitor targeting IKKβ, IκBα and NF-κB p65. NF-κB-IN-22 selectively inhibits the proliferation, migration and invasion of various cancer cells, arrests the cell cycle, and suppresses tumor growth in vivo, while exhibiting low toxicity to normal cells. NF-κB-IN-22 induces DNA damage, ROS production and apoptosis through endoplasmic reticulum stress and mitochondrial apoptotic pathways. NF-κB-IN-22 inhibits the phosphorylation of IKKβ, IκBα and NF-κB p65, blocks the NF-κB signaling pathway, and suppresses the nuclear translocation of NF-κB p65. NF-κB-IN-22 reverses the resistance to cisplatin (HY-17394). NF-κB-IN-22 can be used in research related to lung cancer, gastric cancer and liver cancer.

NF-κB-IN-22 (complex 11) (72 h) potently inhibits the proliferation of NCI-H460, HepG-2, HCT-116, and MGC-803 cancer cells, with IC50 values ranging from 0.38 to 0.91 μM after 72 h of incubation[1].
NF-κB-IN-22 (72 h) effectively inhibits the proliferation of cisplatin-sensitive A549 and Cisplatin-resistant A549/CDDP lung cancer cells, with IC50 values of 0.31 μM and 0.57 μM, respectively; it exhibits low toxicity toward normal HL-7702 and BEAS-2B cells[1].
NF-κB-IN-22 (1 mM) remains stable in PBS at pH 7.4 and 5.5, undergoes partial degradation in cell culture medium containing 10% FBS, and can undergo reductive activation in the presence of ascorbic acid to release ligand 6 and Oxaliplatin[1].
NF-κB-IN-22 (10 μM; 12 h) induces significantly higher intracellular platinum accumulation in A549 and A549/CDDP cells than Oxaliplatin (HY-17371) or the Oxaliplatin/1a combination[1].
NF-κB-IN-22 (5 μM; 24 h with TNF-α stimulation) effectively inhibits TNF-α-induced activation of the NF-κB pathway in A549 cells by reducing the phosphorylation levels of p65, IKKβ and IκBα[1].
NF-κB-IN-22 (5 μM; 24 h with TNF-α stimulation) effectively blocks TNF-α-induced nuclear translocation of phosphorylated NF-κB/p65 in A549 cells[1].
NF-κB-IN-22 (5 μM; 24 h) effectively induces apoptosis in A549 cells, arrests the cells at the G2/M phase, and significantly inhibits their migration and invasion abilities[1].
NF-κB-IN-22 (5 μM; 24 h) induces significant DNA damage and DNA double-strand breaks in A549 cells[1].
NF-κB-IN-22 (5 μM; 24 h) significantly upregulates the expression of γ-H2AX protein in A549 cells[1].
NF-κB-IN-22 (5 μM; 24 h) induces significant mitochondrial dysfunction in A549 cells, characterized by a 41.72% decrease in mitochondrial membrane potential[1].
