Abstract: This invention is directed to certain dibenzofurancarboxamides and their use as 5HT.sub.3 antagonists having unique CNS, anti-emetic and gastric prokinetic activity void of any significant D.sub.2 receptor binding properties. This invention also describes novel processes necessary for their preparation.

Abstract: This invention relates to certain quinoline-diaryl compounds and their use as leukotriene D.sub.4 antagonists for the treatment of hypersensitive disorders.
