identification of novel S1P1 receptor agonists, the pyrazole derivative 2 emerged as a hit structure. Medicinal chemistry efforts focused not only on improving the potency of the compound but in particular also on resolving its inherent instability issue. This led to the discovery of novel bicyclo[3.1.0]hexane fused thiophene derivatives. Compounds with high affinity and selectivity for S1P1 efficiently reducing
通过旨在鉴定新型S1P 1受体激动剂的高通量筛选活动,吡唑衍生物2成为一种命中结构。药物化学工作不仅着重于提高化合物的效力,而且特别着重于解决其固有的不稳定性问题。这导致了新的双环[3.1.0]己烷稠合噻吩衍生物的发现。鉴定出对S1P 1具有高亲和力和选择性的化合物,可有效减少大鼠的淋巴细胞计数。例如,化合物85在S1P 1和S1P 3上的EC 50值为7和2880 nM。分别在大鼠和狗中具有良好的药代动力学特性,很好地分布在脑组织中,并且有效且剂量依赖性地降低了大鼠的淋巴细胞计数。自发性高血压大鼠口服给药后,S1P 1选择性化合物85仅对动物的苏醒阶段没有表现出对平均动脉压的影响,并且仅影响心率。
