Figure 4 |. Piperidine and benzyl amine cores are optimal molecular linkers.
(A) Chemical structures of the R1 group (phosphonate head) and the R2 group (6,7-dimethoxy quinazoline tail). (B) Chemical structures of cores with corresponding Ki values (mean of at least 2 independent replicates) at pH 7.4. Ki values were determined using 3 nM ENPP1 and 5 μM cGAMP.
