Condensation of 3,5-diacylpyrantriones with various aromatic amines gave a new class of potent, orally active, antiallergic compounds, the 3-[(arylamino)ethylidene]-5-acylpyrantriones, hereafter referred to as pyranenamines, as evaluated not only in the traditional rat passive cutaneous anaphylaxis (PCA) assay but also in the in vitro fragmented rat and primate lung assay. Potencies in the PCA system
Substituted 2H-pyran-2,6(3H)-dione derivatives useful in the treatment of allergic conditions are prepared by reaction of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one with an appropriate aniline.
Pharmaceutical compositions comprising a substituted 3-cinnamoyl-2H-pyran-2,6(3H)-dione and methods of inhibiting the antigen-antibody reaction by administering said compositions. Certain of the 3-cinnamoyl-2H-pyran-2,6(3H)-diones are novel compounds per se.

Substituted 2H-pyran-2,6(3H)-dione derivatives useful in the treatment of allergic conditions are prepared by reaction of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one with an appropriate aniline.
Substituted 2H-pyran-2,6(3H)-dione derivatives, pharmaceutical compositions comprising such derivatives and methods of inhibiting the antigen-antibody reaction by administering said compositions. The active ingredients are the products formed by the reaction of acetonedicarboxylic acid with acetic anhydride followed by reaction with an appropriate amine. Certain of the dione derivatives are novel compounds per se.
