The adamantane scaffold, despite being widely used in medicinal chemistry, is not devoid of problems. In recent years we have developed new polycyclic scaffolds as surrogates of the adamantane group with encouraging results in multiple targets. As an adamantane scaffold is a common structural feature in several P2X7 receptor antagonists, herein we report the synthesis and pharmacological evaluation
尽管金刚烷支架被广泛地用于药物化学中,但是其仍然没有问题。近年来,我们开发了新的多环支架作为金刚烷类的替代物,在多个靶标中均获得了令人鼓舞的结果。由于金刚烷支架是几种P2X7受体拮抗剂的共同结构特征,因此我们在此报告了金刚烷的多种替代选择的合成和药理学评估,这些替代选择均保持了良好的活性。分子建模研究支持化合物与中央孔附近的位点结合,而不是与ATP结合位点结合,从而阐明了新型P2X7拮抗剂的结构要求。
