Phenylalkan(en)oic acid

A phenylalkan(en)oic acid represented by the following formula:

• ##STR191## wherein A is:
• i) --NHCO--,
• ii) --O--,
• iii) --NHSO.sub.2 --,
• iv) --CO--,
• v) --CH.sub.2 --, or
• vi) --CH(OH)--;
• W is:
• i) C.sub.1-13 alkylene,
• ii) phenylene, or
• iii) ##STR192## R.sup.1 is:
• i) a saturated or unsaturated, unsubstituted 4-7 membered monocyclic hetero ring containing one nitrogen as a hetero atom,
• ii) a saturated or unsaturated, 4-7 membered monocyclic hetero ring containing one nitrogen as a hetero atom, wherein said ring is substituted by an oxo group, and wherein said oxo group is present on the carbon atom adjacent to said nitrogen atom, or
• iii) ##STR193## where one of R.sup.2 is a thiazole ring, isothiazole ring, thiadiazoline ring or partially or fully saturated ring thereof, and the other R.sup.2 is a:
• i) hydrogen,
• ii) C.sub.1-4 alkyl, or
• iii) thiazole ring, isothiazole ring, thiadiazoline ring or partially or fully saturated ring thereof, or
• two R.sup.2, taken together with the nitrogen, form an indole ring, an isoindole ring, a quinoline ring, an isoquinoline ring, a carbazole ring, an acridine ring, an oxazole ring, an isooxazole ring, a furazan ring, or a partially or fully saturated ring thereof, or a morpholine ring;
• Y is ethylene or vinylene;
• D is:
• i) --Z--B, or
• ii) ##STR194## Z is C.sub.3-11 alkylene or alkenylene;
• B is ##STR195## or Z, taken together with B, is C.sub.3-22 alkyl;
• R.sup.3 is:
• i) hydrogen,
• ii) halogen,
• iii) C.sub.1-8 alkyl, alkoxy or alkylthio or
• iv) C.sub.2-8 alkenyl, alkenyloxy or alkenylthio;
• n is 1-3;
• R.sup.4 is C.sub.1-7 alkylene;
• R.sup.5 is:
• i) C.sub.1-12 alkyl,
• ii) C.sub.2-12 alkenyl,
• iii) C.sub.5-7 cycloalkyl, or
• iv) phenethyl or phenethyl, wherein the ring is substituted by one C.sub.1-4 alkoxy;
• with the proviso that:
• i) --A--W--R.sup.1 binds to the 3- or 4-carbon in the benzene ring, and
• ii) when W is phenylene or ##STR196## does not represent --O--, --CO--, --CH.sub.2 -- or --CH(OH)--;
• and non-toxic salts thereof.
