report the synthesis and pharmacological characterization of ATX inhibitors based on the 4‐tetradecanoylaminobenzylphosphonic acid scaffold, which was previously found to lack sufficient stability in cellular systems. The new 4‐substituted benzylphosphonic acid and 6‐substituted naphthalen‐2‐ylmethylphosphonic acid analogues block ATX activity with Ki values in the low micromolar to nanomolar range against
Autotaxin (ATX, NPP2) 是核苷酸焦磷酸磷酸二酯酶家族的成员。ATX 通过溶血磷脂酶 D 的活性催化溶血磷脂酰胆碱 (LPC) 的水解裂解,从而产生生长因子样脂质介质溶血磷脂酸 (LPA)。ATX 在转移性和化疗耐药性癌症中高度上调,是介导癌症侵袭和转移的潜在靶点。在此,我们报告了基于 4-十四烷酰氨基苄基膦酸支架的 ATX 抑制剂的合成和药理学表征,此前发现该支架在细胞系统中缺乏足够的稳定性。新的 4-取代苄基膦酸和 6-取代萘-2-基甲基膦酸类似物通过K i阻断 ATX 活性通过混合模式抑制机制,对 FS3、LPC 和核苷酸底物的低微摩尔至纳摩尔范围内的值。所测试的化合物均不抑制相关酶(NPP6 和 NPP7)的活性。此外,这些化合物被评估为七种 LPA 受体 (LPAR) 亚型的激动剂或拮抗剂。类似物22和30 b是两种最有效的 ATX 抑制剂,在体外以剂量依赖性方式抑制
