Abstract
Disclosed are novel alkylarylketocarboxylic acids and 5-substituted tetrazoles represented by the formula ##STR1## wherein Z is aryl or an alkyl of the structure ##STR2## W is a carboxyl moiety or a tetrazole moiety bound to Z at the 5-position of the tetrazole; PA1 R.sub.1 is C.sub.4 -C.sub.12 alkyl where Z is aryl and X is oxygen or is C.sub.5 -C.sub.12 alkyl where Z is alkyl and where Z is aryl and X is a bond; PA1 R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.4 alkyl, hydroxy, C.sub.1 -C.sub.4 alkoxy, halogen, trihalomethyl, nitro, cyano or C.sub.1 -C.sub.4 acyl; PA1 R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are each independently hydrogen or C.sub.1 -C.sub.4 alkyl or R.sub.4 and R.sub.6 or R.sub.5 and R.sub.7 can combine to form a carbocyclic ring; PA1 X is oxygen, or a bond at the ortho or para position; PA1 m is 0, 1 or 2; and PA1 n is 0 or 1, and nontoxic, pharmaceutically acceptable addition salts and carboxylic acid esters thereof.
