Abstract
As a part of ongoing studies in developing new potent anti-inflammatory and analgesic
agents, a series of novel 6-methoxy naphthalene derivatives was efficiently synthesized
and characterized by spectral and elemental analyses. The newly synthesized compounds
were evaluated for their anti-inflammatory activities using carrageenin-induced rat
paw edema model, analgesic activities using acetic acid induced writhing model in
mice and anti-pyretic activity using yeast induced hyperpyrexia method as well as
ulcerogenic effects. Among the synthesized compounds, thiourea derivative (6a, e) exhibited higher anti-inflammatory activity than the standard drug naproxen in reduction
of the rat paw edema (88.71, 89.77%) respectively. All of the non-carboxylic tested compounds were found to have promising
anti-inflammatory, analgesic and antipyretic activity, while were devoid of any ulcerogenic
effects.
