Phenylethylamine and phenoxylalkylamine fragments were introduced into pyridazinone derivatives (as α1-adrenoceptor antagonist) for the first time. 30 new compounds of pyridazinone were designed and synthesized. The structures of the new compounds were identified by 1H NMR, IR and HRMS spectra. Target compounds have been assayed with function analysis in anococcyeus muscle. The results indicate that 28 target compounds have good blocking activity to α1-adrenoceptor (pA2>6.00), The pA2 of compounds 6o, 6p, 6q, 6v, 6x, 6y, 10c and 10d were beyond 7.00.

Key words: synthesis, biological activity, α1-adrenoceptor antagonist, pyridazinone
