title: (1,4-Benzothiazinyloxy)alkylpiperazine derivatives as potential antihypertensive agents.
abstract: A series of compounds having a piperazine moiety variously linked to the benzothiazine nucleus were synthesized and evaluated for their in vitro alpha-adrenoceptor affinity by radioligand receptor binding assays. Some compounds bearing a oxyalkyl-(2-methoxyphenyl)piperazine side chain were good alpha1-adrenoreceptor ligands.
