  Novel benzothiophene-, benzofuran-, and naphthalenecarboxamidotetrazoles as potential antiallergy agents

  摘要：

  The synthesis and antiallergic activity of a series of novel benzothiophene-, benzofuran-, and naphthalenecarbox-amidotetrazoles are described. A number of the compounds inhibit the release of histamine from anti-IgE stimulated basophils obtained from allergic donors. Optimal inhibition is exhibited in benzothiophenes with a 3-alkoxy substituent in combination with a 5-methoxy, 6-methoxy, or a 5,6-dimethoxy group. Compounds 13c (CI-959) also inhibited respiratory burst of human neutrophils and the release of mediators from anti-IgE-stimulated human chopped lung.

  have discovered a novel series of compounds, which contain a 1-benzo[b]thiophen or a benzofuran group as the central aromatic group. Our investigation of this series of compounds has enhanced our understanding of the importance of binding sites within the CB1 receptor for favourable CB1 potency. Our understanding of these factors allowed us to modify the structure of a 1-benzothiophen derivative and improve

  The surface levels of ICAM-1 and E-selectin on activated endothelial cells can be reduced by 3-alkoxybenzo[b]thiophene-2-carboxamides. This property is shared by several N-alkylthiopyridine substituted imides. Combining structural elements of these two diverse series lead to a new class of small molecule inhibitors of adhesion molecule expression.
