摘要

The metabolites of 6-ethyl-3-(1H-tetrazol-5-yl) ehromone (AA-344)(I), an orally effective antiallergic agent, and their analogues were synthesized to confirm the proposed structures and to determine their activity in the rat passive cutaneous anaphylaxis (PCA) test A glucuronic acid metabolite (6) was assigned the structure 24b, 1-deoxy 1-[~-(6-etliylchromon- 3-yl) tetrazol-l-yl]-~-~-glucopyranuronate, by the comparison of I3C NMR, mass spectra, ...
