to 3N-substituted-azabicyclo[3.1.0]hexane derivatives were designed and synthesized as inhibitors of T-type calcium channels. Among the synthesized compounds, 3N-R-substituted azabicyclo[3.1.0]hexane carboxamide derivatives containing 5-isobutyl-1-phenyl-pyrazole ring exhibited potent and selective T-channel inhibition and good metabolic stability without CYP450 inhibition. Compounds 10d and 10e contained
设计并合成了一系列新的芳基化合物,包括与3 N-取代的氮杂双环[3.1.0]己烷衍生物共轭的苯并[ d ]咪唑/异恶唑/吡唑,并作为T型钙通道抑制剂。在合成的化合物中,含有5-异丁基-1-苯基-吡唑环的3 N - R-取代的氮杂双环[3.1.0]己烷甲酰胺衍生物表现出有效的和选择性的T通道抑制作用,并且具有良好的代谢稳定性,而没有CYP450抑制作用。化合物10D和10E含有疏水取代基在3- Ñ位和表现出在体外效力强效,以及在大鼠神经性疼痛减轻。
