Takinib is a novel, potent and selective TAK1 inhibitor with an IC50 of 9.5 nM. Takinib induces apoptosis following TNF-α stimulation in cell models of rheumatoid arthritis and metastatic breast cancer. Takinib is an inhibitor of autophosphorylated and non-phosphorylated TAK1 that binds within the ATP-binding pocket and inhibits by slowing down the rate-limiting step of TAK1 activation. Overall, Takinib is an attractive starting point for the development of inhibitors that sensitize cells to TNF-α-induced cell death, with general implications for cancer and autoimmune disease treatment. Tumor necrosis factor alpha (TNF-α) has both positive and negative roles in human disease. In certain cancers, TNF-α is infused locally to promote tumor regression, but dose-limiting inflammatory effects limit broader utility. In autoimmune disease, anti-TNF-α antibodies control inflammation in most patients, but these benefits are offset during chronic treatment. TAK1 acts as a key mediator between survival and cell death in TNF-α-mediated signaling.
ln Vitro |
After TNF-α activation, tikinib (10–10,000 nM; 24 hours) causes MDA-MB-231 cells to undergo apoptosis [1]. Takinib (10 μM; 0–1 hour) decreases p65 and IKK phosphorylation [1]. The chemical foundation for PfPK9 (KD(app) 0.46 μM) malaria inhibitor development is provided by tikinib [3]. TAK1Thr184/187, STAT3Tyr705, and STAT3Ser727 phosphorylation are induced in RASF treated with IL-1β (10 ng/mL; 30 minutes) by tikinib (2 hours; 0.1-20 μM; human RASF) [4].

ln Vivo |
In a mouse model of type II collagen-induced arthritis (CIA) of rheumatoid arthritis, tikinib (50 mg/kg; i.p.; once daily on days 18–36) lowers clinical scores [4]. ?In Hodgkin's lymphoma xenografted NSG mice, takinib (50 mg/kg; oral gavage; daily till day 17) inhibits the formation of tumors [5].

Cell Assay |
Western Blot Analysis[1]
Cell Types: Breast cancer cell line MDA-MB-231 Tested Concentrations: 10 μM Incubation Duration: 5, 15, 30, 60 minutes Experimental Results: IKK and p65 were maximally phosphorylated at 15 minutes, indicating activation of NF -κB pathway, whereas p38 phosphorylation peaked at 30 min. Western Blot Analysis[4] Cell Types: IL-1β treatment (10 ng/mL; 30 minutes) RASF Tested Concentrations: 0.1-20 µM Incubation Duration: 2 hrs (hours) Experimental Results: Induction of TAK1Thr184/187, STAT3Tyr705 and STAT3Ser727 phosphorylation. |
Animal Protocol |
Animal/Disease Models: Male DBA/1 mouse (CIA arthritis model) [4]
Doses: 50 mg/kg Route of Administration: intraperitoneal (ip) injection; one time/day starting on days 18-36 Experimental Results: compared to vehicle control , clinical arthritis scores diminished. Animal/Disease Models: Female NSG mice (8 weeks old) [5] Doses: 50 mg/kg Route of Administration: po (oral gavage); one time/day until 17 days Experimental Results: Tumor growth slowed down and tumor size/weight diminished. |

Solubility (In Vitro) |

Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (7.76 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (7.76 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
