(2-Carboxy-1,4-dihydro-4-oxoquinolyl)oxamic acids and (2-carboxy-1,4-dihydro-4-oxobenzo[h]quinolyl)oxamic acids as antiallergy agents.
A group of (2-carboxy-1,4-dihydro-4-oxoquinolyl)oxamic acids (5) containing the oxamic acid group in the 5,6, or 7 positions were synthesized and investigated for antiasthma activity as indicated by the passive cutaneous anaphylaxis (PCA) reaction in rats. Also synthesized and investigated were two (2-carbosy-1,4-dihydro-4-oxobenzo[h]-quinolyl)oxamic acids (9 and 10). Several of the compounds synthesized (viz. 5e, 5f, and 10) showed activity in the PCA test approximately 25 times that shown by disodium cromoglycate (1), as measured by the ID50 doses.
