  Highly Selective and Orally Active Inhibitors of Type IV Collagenase (MMP-9 and MMP-2):  N-Sulfonylamino Acid Derivatives

  摘要：

  Various N-sulfonylamino acid derivatives were synthesized and evaluated for their in vitro and in vivo activities to inhibit type IV collagenase (MMP-9 and MMP-2). When the amino acid residue and the sulfonamide moiety were modified, their inhibitory activities were greatly affected by the structure of the sulfonamide moiety. A series of aryl sulfonamide derivatives containing biaryl, tetrazole, amide, and triple bond were found to be potent and highly selective inhibitors of MMP-9 and MMP-2 In addition, these compounds were orally active in animal models of tumor growth and metastasis. These results revealed the potential of the N-sulfonylamino acid derivatives as a new type of candidate drug for the treatment of cancer.

  摘要：

  新型前列腺素D（2）（PGD（2））受体拮抗剂被合成为具有磺酰胺基团的双环[2.2.1]庚烷环系的潜在新型抗过敏药。它们中的一些在放射性配体结合和cAMP形成分析中显示PGD（2）受体的强效拮抗作用，IC（50）值低于50 nM，而TXA（2）和PGI（2）受体的拮抗作用小得多。这些有效的PGD（2）受体拮抗剂经口服给予后，可显着抑制各种变应性炎症反应，例如变应性鼻炎，结膜炎和哮喘模型中血管通透性的增加。最初在我们实验室中合成的PGD（2）受体拮抗剂的优异药理学特征具有潜在的重大临床意义。
