The present invention provides novel phenylacetamide derivatives having the following formula
wherein:
X is a hydrogen, halogen, hydroxy, nitro, amino, R1, NR1R2, NHR1 or OR1 wherein R1 and R2 are an optionally substituted C1 -8 alkyl, cycloalkyl or benzyl group, respectively; Y, which may be the same or different when p is greater than 1, is a hydrogen, halogen, methylenedioxy, hydroxy, trifluoromethyl, R3 or OR3 wherein R3 is an optionally substituted C1 -8 alkyl or benzyl group;
n is an integer from 1 to 6; and
p is an integer from 1 to 5; and pharmaceutically acceptable salts thereof which have powerful analgesic and anti-inflammatory activities.
The invention also provides processes for preparing these compounds and pharmaceutical compositions containing them as an active ingredient.
