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
一个新的系列4- acylaminopyrazolo [3,4的合成d ]嘧啶类活性对σ-1受体(σ 1个R)被报告。从市售的1 H-吡唑并[3,4- d ]嘧啶-4-胺开始,使用两到三步的方法有效地制备了化合物。甲SAR研究表明,σ 1 - [R需要的相对高亲脂性的取代基在中心骨架的两侧的存在,而选择性相对于所述σ 2 R可以通过缩短它的碱性氮的距离来改善。化合物9a是体外活性和选择性最高的化合物 在小鼠的几种疼痛模型中,其衍生物具有强镇痛作用,表明其拮抗行为。
