A series of 3-substituted pyridothienopyrimidin-4(3H)-ones has been synthesized from 2,7,9-trimethyl-4H-pyrido[3',2':4,5]thieno-[3,2-d] [ 1,3]oxazin-4-one. These compounds have been evaluated for analgesic, anti-inflammatory and antipyretic activities. The ulcerogenic effect of the compounds has been also studied.
