tcsc0028870 CU CPT 22

CU CPT 22 is a toll-like receptor 1 and 2 (TLR1/2) inhibitor with an IC₅₀ of 0.58 µM.

IC50 & Target: IC50: 0.58 μM (TLR1/2)^[1]

In Vitro: CU CPT 22 is a toll-like receptor 1 and 2 (TLR1/2) inhibitor with an IC₅₀ of 0.58±0.09 µM. It is demonstrated that CU CPT 22 is able to compete with Pam₃CSK₄ for binding to TLR1/2 with an inhibition constant (K_i) of 0.41±0.07 µM, which is consistent with its potency observed in the whole cell assay. Increasing the concentration of CU CPT 22 to 6 µM decreases the anisotropy to background levels. It is found that CU CPT 22 inhibits TLR1/2 signaling without affecting other TLRs, showing it is highly selective in intact cells. CU CPT 22 is found to have no significant cytotoxicity at various concentrations up to 100 µM in RAW 264.7 cells. The result demonstrates that CU CPT 22 can inhibit about 60% of TNF-αand 95% of IL-1β at 8 µM^[1].
