Synthesis and antiallergy activity of 4-oxo-4H-pyrido[1,2-a]thieno[2,3-d]pyrimidines
摘要:
A series of 4-oxo-4H-pyrido[1,2-a]thieno[2,3-d]pyrimidines with substitutions in the 2, 3, and 7 positions was prepared. The compounds were evaluated in the rat passive cutaneous anaphylaxis test for antiallergy activity. Several compounds had potent oral activity and were found to be superior to disodium cromoglycate and doxantrazole. Structure-activity relationships are discussed.

aim to develop new potent and selectiveligands of 5‐HT3‐type serotonin receptors and to acquire more information on their structure‐affinity relationships, newthieno[2,3‐d]pyrimidine derivatives 32–39 were synthesized and their binding to 5‐HT3 versus 5‐HT4 receptors was studied. Some of these new compounds exhibit good affinity for cortical 5‐HT3 receptors, but not for 5‐HT4 receptors. Among these
Oxo-pyrido[1,2-a]thienopyrimidine compounds, salts thereof, methods of production, intermediates in their production, pharmaceutical compositions containing said compounds and methods for treating allergies using said compositions are disclosed.
