  biological evaluation of a number of differently substituted 3,6-diamino-1H-pyrazolo[3,4-b]pyridine derivatives are reported. From the inhibition results on a selection of disease-relevant protein kinases [IC50 (μM) DYRK1A = 11; CDK5 = 0.41; GSK-3 = 1.5] we have observed that 3,6-diamino-4-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile (4) constitutes a potential new and simple lead compound in the

  Abstract magnified image The acetylation reaction of the differently substituted 3,6‐diamino‐1H‐pyrazolo[3,4‐b]pyridine‐5‐carbonitrile derivatives 1, 2, 3, 4, 5, 6 is reported. The structure of the resulting acetamides has been investigated and confirmed by analytical, spectroscopic, and chemical transformations. From these studies, we conclude that, in general, under mild conditions, and using acetic anhydride, when free, the N(1)H moiety is a more reactive center respect to the C(3)NH2 and C(6)NH2 groups. This trend is reversed when no steric hindrance due to presence of a phenyl group at C4 drives the preferred acetylation to C(3)NH2, as it is evident by comparing the observed results from precursor 1 with 3. When N1 is blocked, the (C3)NH2 group undergoes preferential acetylation over the (C6)NH2 site, which only has been mono (or diacetylated) at reflux. Computational analyses based on DFT studies have been extensively used to explain the observed reactivities. J. Heterocyclic Chem., (2010).
