  high requirements for the drug selectivity, pharmacokinetic, and safety profile. We describe the identification of a highly selective druglike 1H-pyrazolo[3,4-d]pyrimidine SGK1 inhibitor 17a that matches both safety and pharmacokinetic requirements for oral dosing. Rational compound design was facilitated by a novel hSGK1 co-crystal structure, and multiple ligand-based computer models were applied to guide

  In a method for producing a de-dimethoxybenzylated compound by removing a dimethoxybenzyl group from a compound containing a dimethoxybenzyl group bonded to a nitrogen atom in the presence of an acid, the de-dimethoxybenzylated compound is obtained by removing the dimethoxybenzyl group without forming a poorly soluble product resulting from the removed dimethoxybenzyl group. The de-dimethoxybenzylation reaction is carried out in the presence of triphenylphosphine or diethylthiourea.
