摘要：

We report the synthesis and biological evaluation of a new series of 8-oxoadenines substituted at the 9-position with a 4-piperidinylalkyl moiety. In vitro evaluation of the piperidinyl-substituted oxoadenines 3a-g in human TLR7- or TLR8-transfected HEK293 cells and in human PBMCs indicated that TLR7/8 selectivity/potency and cytokine induction can be modulated by varying the length of the alkyl linker. Oxoadenine 3f containing a 5-carbon linker was found to be the most potent TLR7 agonist and IFN alpha inducer in the series whereas 3b possessing a 1-carbon linker was the most potent TLR8 agonist.
