Synthesis of aminothienopyrimidine and thienotriazolopyrimidine derivatives as potential anticonvulsant agents.

New aminothienopyrimidines and derivatives of the new thienotriazolopyrimidine ring system were synthesized to investigate their anticonvulsant activity. The tricyclic compounds 6a, c, e, f, m, o and p and two bicyclic derivatives 4f and 4o were tested. The pharmacological screening results are reported and discussed.
