pathophysiological functions of these enzymes are not fully understood due to lack of potent and selective NTPDase inhibitors. Herein, a series of oxoindolin hydrazine carbothioamide derivatives is synthesized and screened for NTPDase inhibitory activity. Four compounds were identified as selective inhibitors of h-NTPDase1 having IC50 values in lower micromolar range, these include compounds 8b (IC50 = 0.29 ± 0
外核苷三磷酸二磷酸二氢水解酶(NTPDases)是一种外酶,在三磷酸核苷和二磷酸核苷水解为单磷酸核苷中起重要作用。NTPDase1,-2,-3和-8是此酶家族的膜结合成员,负责调节细胞外环境中核苷酸的水平。但是,由于缺乏有效的和选择性的NTPDase抑制剂,这些酶的病理生理功能尚不完全清楚。本文中,合成了一系列的氧吲哚肼肼碳硫酰胺衍生物,并筛选了其对NTPDase的抑制活性。四种化合物被确定为的选择性抑制剂H-NTPDase1具有较低的微摩尔范围的IC 50值,包括化合物8b(IC 50 = 0.29±0.02 µM),8e(IC 50 = 0.15±0.009 µM),8楼(IC 50 = 0.24±0.01 µM)和8升(IC 50 = 0.30±0.03 µM)。同样,复合8k(IC 50 = 0.16±0.01 µM)被发现具有选择性H-NTPDase2抑制剂。的情况下H-NTPDase3,最有效的抑制剂是化合物
