Compounds 1 or 2 which possess dual-acting PAF antagonist/TxSI in a previous paper were modified and evaluated for the dual-acting activity. It was found that several compounds were potent dual-acting PAF antagonist/TxSI in and ex vivo. 6-(2-Chlorophenyl)-3-[4-[(E /Z)-6-ethoxvcarbonyl-1-(3-pyridyl)-1-hexenyl]phenylmethyl]-8,11-dimethyl-2,3.4,5-tetrahydro-8H-pyrido[4',3': 4.5]thieno[3.2-f][1,2,4]triazolo[4,3-a][1.4]diazepine (12) is excellent orally dual-acting PAF antagonist/TxSI.
