A series of furo [3, 2-b] indole carboxylic acids, tetrazoles, and carbamoyltetrazoles was prepared and tested in vitro with use of a model of active pulmonary anaphylaxis, the modified Schultz-Dale Test (SDT). In this model, isolated guinea pig lung strips are repeatedly challenged with antigen in the presence of an antihistamine (HJ.
