Rational designs of small-molecule inhibitors targeting protein-protein interfaces have met little success. Herein, we have designed a series of triazole derivatives with a novel scaffold to specifically intervene with the interaction of TLR8 homomerization. In multiple assays, TH1027 was identified as a highly potent and specific inhibitor of TLR8. A successful solution of the X-ray crystal structure of TLR8 in complex with TH1027 provided an in-depth mechanistic insight into its binding mode, validating that TH1027 was located between two TLR8 monomers and recognized as an unconventional pocket, thereby preventing TLR8 from activation. Further biological evaluations showed that TH1027 dose-dependently suppressed the TLR8-mediated inflammatory responses in both human monocyte cell lines, peripheral blood mononuclear cells, and rheumatoid arthritis patient specimens, suggesting a strong therapeutic potential against autoimmune diseases.

Both EGFR and VEGFR-2 play a critical role in tumor growth, angiogenesis and metastasis, and targeting EGFR and VEGFR-2 simultaneously represents a promising approach to cancer treatment. In this work, a series of novel quinazoline- and thiourea-containing sorafenib analogs (10a–v) were designed and synthesized as EGFR and VEGFR-2 dual TK inhibitors. Their in vitro enzymatic inhibitory activities against EGFR and VEGFR-2, and antiproliferative activities against HCT-116, MCF-7 and B16 cell lines were evaluated and described. Most of the compounds showed potent activities against both cell lines and TK kinases. Compounds 10b and 10q which exhibited the most potent inhibitory activities against EGFR (IC50 = 0.02 μM and 0.01 μM, respectively), VEGFR-2 (IC50 = 0.05 μM and 0.08 μM, respectively), and good antiproliferative activities, also displayed competitive anti-tumor activities than sorafenib in vivo by B16 melanoma xenograft model test.
