The replacement of acylamino by cyclic substituents in the position 4 of the pyrazolo[3,4-d]pyrimidine scaffold, led to highly active sigma-1 receptor (σ1R) ligands. Phenyl or pyrazolyl groups were the best in terms of affinity for the σ1R and the 4-(1-methylpyrazol-5-yl) derivative, 12f, was the most selective. Compound 12f is also one of the best σ1R ligands ever described in terms of lipophilic
new series of 4-acylaminopyrazolo[3,4-d]pyrimidines active on the sigma-1 receptor (σ1R) is reported. Compounds were efficiently prepared using a two to three step process starting from commercially available 1H-pyrazolo[3,4-d]pyrimidin-4-amine. A SAR study shows that the σ1R requires the presence of relatively highly lipophilic substituents at opposite sides of the central scaffold, while selectivity
