  Preliminary evaluation of a 3H imidazoquinoline library as dual TLR7/TLR8 antagonists

  摘要：

  Toll-like receptors (TLR) -7 and -8 are thought to play an important role in immune activation processes underlying the pathophysiology of HIV and several clinically important autoimmune diseases. Based on our earlier findings of TLR7-antagonistic activity in a 3H imidazoquinoline, we sought to examine a pilot library of 3H imidazoquinolines for dual TLR7/8 antagonists, since they remain a poorly explored chemotype. 2D-NOE experiments were employed to unequivocally characterize the compounds. A quinolinium compound 12, bearing p-methoxybenzyl substituents on N3 and N5 positions was identified as a lead. Compound 12 was found to inhibit both TLR7 and TLR8 at low micromolar concentrations. Our preliminary results suggest that alkylation with electron-rich substituents on the quinoline N5, or conversely, elimination of the fixed charge of the resultant quaternary amine on the quinolinium may yield more active compounds.
