A series of sydnone derivatives containing styryl ketone moiety, 4-(1-oxo-3-(substituted aryl)-2-propenyl)-3-(4-methylphenyl)sydnones ( 6a-i) has been synthesized and characterized by spectral data. The synthesized compounds have been screened for preliminary antibacterial activity by cup plate method and analgesic activity by the method of acetic acid induced writhing in mice. The chloro and nitro derivatives showed good antibacterial activity against both gram positive and gram negative bacteria while the chloro and furyl derivatives exhibited highest analgesic effect among the series.
