The study is focused on a series of 5-arylidenehydantoin derivatives with a phenylpiperazine-hydroxypropyl fragment at N3 of the hydantoin ring. The compounds were assessed on their affinity for α(1)-adrenoceptors and evaluated in functional bioassays for their antagonistic properties. Crystal structures
