ABSTRACT:
A novel series of 5-alkoxyimidazo[1,2-a]quinoline-2-carboxylic acids and esters thereof of the formula (I) ##STR1## wherein R is hydrogen or alkyl having from one to five carbon atoms; each of R.sup.1 and R.sup.2 is hydrogen, alkyl having from one to five carbon atoms, alkoxy having from one to five carbon atoms, fluoro, chloro, bromo, methylthio or methylsulfinyl, with the proviso that when R.sup.1 and R.sup.2 are both bulky groups, i.e. branched chain alkyl or branched chain alkoxy, they are located on non-adjacent positions; and when R.sup.1 and R.sup.2 are taken together they form tetramethylene, 1,3-butadienyl, methylenedioxy or ethylenedioxy, each said group being attached to adjacent carbon atoms of the benzenoid ring; R.sup.3 is alkyl having from one to five carbon atoms; and the pharmaceutically acceptable cationic salts of those compounds wherein R is hydrogen; compositions thereof; their use as antiallergy agents and certain intermediates for the preparation of said compounds of formula (I).
