useful target in anticancer therapy. Herein, we report the synthesis and biological evaluation of new ADAM-17 inhibitors containing an arylsulfonamidic scaffold. Among the new potential inhibitors, two very promising compounds 17 and 18 were discovered, with a nanomolar activity for ADAM-17 isolated enzyme. These compounds proved to be also the most potent in inhibiting soluble ALCAM release in cancer
活化的白细胞粘附分子(ALCAM)在肿瘤生物学和进展中起着重要作用。我们以前的研究表明,ALCAM在上皮性卵巢癌(EOC)细胞表面表达,并通过ADAM-17介导的脱落以可溶形式释放。此过程与EOC细胞的运动性和侵袭性有关,ADAM-17的非特异性抑制剂会降低EOC的细胞运动性和侵袭性。因此,ADAM-17可能代表抗癌治疗的新靶标。在此,我们报告了含有芳基磺酰胺基支架的新型ADAM-17抑制剂的合成和生物学评估。在新的潜在抑制剂中,两种非常有前途的化合物17和18被发现具有ADAM-17分离酶的纳摩尔活性。这些化合物被证明也是抑制癌细胞中可溶性ALCAM释放的最有效剂,对A2774和SKOV3细胞系表现出纳摩尔活性。
