A novel series of 4-oxo-spirochromane bearing primary sulfonamide group were synthetized as Carbonic Anhydrase inhibitors (CAIs) and tested for their management of neuropathic pain. Indeed, CAs have been recently validated as novel therapeutic targets in neuropathic pain. All compounds, here reported, showed strong activity against hCA II and hCA VII with KI values in the low or sub-nanomolar range
合成一系列新型的带有4-氨基氧代螺氨基甲烷的伯磺酰胺基团作为碳酸酐酶抑制剂(CAIs),并测试其对神经性疼痛的治疗作用。实际上,最近已经证实CA是神经性疼痛中的新型治疗靶标。本文报道的所有化合物均显示出针对hCA II和hCA VII的强活性,其K I值处于低或亚纳摩尔范围内。在奥沙利铂诱发的神经病动物模型中,两种化合物(6d和6l)显示出良好的神经痛减轻作用,且持续时间长于药物参考乙酰唑胺。
