Fluorescence anisotropy titration: a) titration of the TLR1/2 protein into the rhodamine-labeled Pam3CSK4 results in significant increase of fluoresence anistropy. Addition of CU-CPT22 competes with Pam3CSK4, resulting in lower fluoresence anistropy, demonstrating competitive binding between CU-CPT22 and Pam3CSK4 for TLR1/2. Data were fitted using a one-site competition model (R2 > 0.98). b) Normalized binding of CU-CPT22 compared with the negative control, compound 6.
