Novel indolecarboxamidotetrazoles as potential antiallergy agents
摘要:
The synthesis and antiallergic potential of a series of novel indolecarboxamidotetrazoles are described. A number of compounds inhibit the release of histamine from anti-IgE-stimulated basophilic leukocytes obtained from allergic donors. Optimal inhibition is exhibited by compounds with 3-alkoxy, 5-methoxy, and 1-phenyl substituents on the indole core structure. Compound 8d (5-methoxy-3-(1-methylethoxy)-1-phenyl-N-1H-tetrazol-5-yl-1H -indole-2-carboxamide; designated CI-949) is a potent inhibitor of histamine release from human basophils and from guinea pig and human chopped lung.

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.
