Assay for LPS binding to PBMCs | PBMCs were suspended in BSA solution (phosphate-buffered saline containing 0.1% BSA and 0.01% sodium azide). In a total volume of 50 μL, PBMCs (3 × 105 cells) were incubated with TAK-242, anti-human CD14 monoclonal antibody (MAb) MEM-18, or anti-human CC-chemokine receptor 5 (CCR5) MAb as a negative control for 30 mins at 4 °C. The cells were further incubated with 50 ng/mL LPS from E. coli serotype O55:B5 conjugated with Alexa Fluor 488 per milliliter in the presence of human serum at a final concentration of 1% for 45 mins at 37 °C. After washing twice with BSA solution, 1 × 104 cells were analyzed by flow cytometry using CytoACE300 cytofluorometer. The assays were performed in triplicate for each preparation of PBMCs obtained from four different donors. Specific LPS binding was estimated by subtracting the percentage of LPS-binding cells in the absence of LPS from that in the presence of LPS. |

IC50: With IC50 of 1.1 to 11 nM, TAK-242 inhibited LPS-induced NO production, tumor necrosis factor-alpha and interleukin (IL)-6 in RAW264.7 cells and mouse peritoneal macrophages [1].
Toll, a member of the Toll-like receptor (TLR) family, was identified as a gene product essential for the development of embryonic dorsoventral polarity in Drosophila melanogaster. Moreover, it has been also found to play a critical role in the antifungal response of flies. TAK-242 (resatorvid), a cyclohexene derivative, is recongnizred as a novel small-molecule compound selectively inhibiting TLR4 signaling.
In vitro: A previous in-vitro study showed that TAK-242 could inhibit the production of lipopolysaccharide-induced inflammatory mediators by binding to the intracellular domain of TLR4 using coimmunoprecipitation approach. Among 10 different human TLRs, TAK-242 selectively bound to TLR4. These findings suggested that TAK-242 could selectively bind to TLR4 and disrupted the interaction of TLR4 with adaptor molecules, thereby inhibiting TLR4 signal transduction and its downstream signaling [2].
In vivo: Preclinical animal study demonostrated that the acute restraint stress exposure upregulateed TLR-4 expression both at the mRNA and protein level in rat. TAK-242 pre-stress administration prevented the accumulation of potentially deleterious inflammatory and oxidative/nitrosative mediators in the brain frontal cortex of rats. These finding s indicated that the use of TAK-242 or other TLR-4 signalling pathway inhibitory compounds could be considered as a potential therapeutic adjuvant strategy to constrain the inflammatory process taking place after stress exposure and in stress-related neuropsychiatric diseases [3].
Clinical trial: To evaluate whether TAK-242, a small-molecule inhibitor of Toll-like receptor-4–mediated signaling, suppresses cytokine levels and improves 28-day all-cause mortality rates in patients with severe sepsis has been conducted in Japan, the U.S. and Europe by Takeda Pharmaceutical Company Limited ("Takeda"). However, following a thorough review of development strategy, Takeda has concluded that TAK-242’s profile does not meet the criteria to support continuation of further development activities. This decision has not been influenced by any concerns over the safety or efficacy of the compound [4].
