  3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives: inhibitors of immune complex induced inflammation

  摘要：

  3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives were evaluated in the dermal and pleural reverse passive Arthus reactions in the rat. In the pleural test these compounds were effective in reducing exudate volume and accumulation of white blood cells. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin. The structural requirements for inhibiting the Arthus reactions were studied by systematic chemical modification of 1. These structure-activity relationship studies revealed that nitrogen 1' of the hydrazino group is essential for activity and must be electron rich, whereas chemical modifications of other sites of 1 had only a modest effect on activity.

  Benzoxazole Derivatives as Novel 5-HT₃ Receptor Partial Agonists in the Gut

  摘要：

  A series of benzoxazoles with a nitrogen-containing heterocyclic substituent at the 2-position was prepared and evaluated for 5-HT3 partial agonist activity on isolated guinea pig ileum. The nature of the substituent at the 5-position of the benzoxazole ring affected the potency for the 5-HT3 receptor, and the 5-chloro derivatives showed increased potency and lowered intrinsic activity. 5-Chloro-7-methyl-2-(4-methyl-1-homopiperazinyl)benzoxazole (6v) exhibited a high binding affinity in the same range as that of the 5-HT3 antagonist granisetron, and its intrinsic activity was 12% of that of 5-HT. Compound 6v inhibited 5-HT-evoked diarrhea but did not prolong the transition time of glass beads in the normal distal colon even at a dose of 100 times the ED50 for diarrhea inhibition in mice. Compounds of this type are expected to be effective for the treatment of irritable bowel syndrome without the side effect of constipation.

  Previously, we explored 2-(4-(4-(bromo-methoxybenzamido)benzylamino)phenyl) benzazole derivatives as anti-heparanase agents, proposing this scaffold for development of broadly effective heparanase inhibitors. Herein, we report an extended investigation of new symmetrical 2-aminophenyl-benzazolyl-5-acetate derivatives, proving that symmetrical compounds are more effective than asymmetrical analogues,

  乙酰肝素酶是唯一的哺乳动物内毒素-β- d-葡糖醛酸糖苷酶涉及多种主要疾病。乙酰肝素酶表达的上调增加了肿瘤的大小，血管生成和转移，代表了在抗癌领域中已被验证的靶标。迄今为止，仅描述了几种小分子抑制剂，但尚未通过临床前开发获得。以前，我们探索了2-（4-（4-（溴-甲氧基苯甲酰胺基）苄氨基）苯基）苯并唑衍生物作为抗乙酰肝素酶的药物，建议将该支架用于开发广泛有效的乙酰肝素酶抑制剂。本文中，我们报告了对新的对称的2-氨基苯基-苯并甲氮基-5-乙酸酯衍生物的扩展研究，证明了对称化合物比不对称类似物更有效，其中最有效的化合物为7g，在纳摩尔浓度下对乙酰肝素酶有活性。对作用最佳的化合物5c和7g进行了分子对接研究，以使它们与酶的相互作用合理化。此外，侵袭分析证实了化合物5c，7a和7g的抗转移潜力，证明抑制了肿瘤细胞中促血管生成因子的表达。
