synthetic inhibitors for ATX have resembled the lipid chemotype of the native ligand; however, a small number of inhibitors have been described that deviate from this common scaffold. Herein, we report the structure–activity relationships (SAR) of a previously reported small molecule ATX inhibitor. We show through enzyme kinetics studies that analogues of this chemotype are noncompetitive inhibitors, and
Autotaxin(ATX)是一种分泌的酶,负责将溶血磷脂酰胆碱(LPC)水解为生物活性溶血磷脂酸(LPA)和胆碱。ATX-LPA信号通路与细胞存活,迁移和增殖有关。因此,抑制ATX是许多疾病的公认治疗靶标,包括纤维化疾病,癌症和炎症等。许多已开发的ATX合成抑制剂与天然配体的脂质化学型相似。然而,已经描述了少数与该普通支架不同的抑制剂。在本文中,我们报告了先前报道的小分子ATX抑制剂的结构-活性关系(SAR)。通过酶动力学研究表明,这种化学型的类似物是非竞争性抑制剂,
