    Discovery of selective 2,4-diaminoquinazoline toll-like receptor 7 (TLR 7) agonists
    摘要:
    The discovery of a novel series of highly potent quinazoline TLR 7/8 agonists is described. The synthesis and structure-activity relationship is presented. Structural requirements and optimization of this series toward TLR 7 selectivity afforded the potent agonist 48. Pharmacokinetic and pharmacodynamic studies highlighted 48 as an orally available endogenous interferon (IFN-alpha) inducer in mice. (C) 2018 Elsevier Ltd. All rights reserved.

    off-target activity. The stereochemistry of the amino alcohol was found to influence the TLR7/8 selectivity with the (R) isomer resulting in selective TLR8 agonism. Lead optimization toward a dual agonist afforded (S)-3-((2-amino-8-fluoroquinazolin-4-yl)amino)hexanol 31 as a potent analog, being structurally different from previously described dual agonists (McGowan J.
