New 2H-1,4-benzothiazin-3(4H)-one derivatives possessing (4-phenyl-1-piperazinyl)alkyl moieties at the 2-position were synthesized and tested for calcium antagonistic and calmodulin antagonistic activities. Antihypertensive effects in spontaneously hypertensive rats were also evaluated. In general, these compounds were rather weak calcium channel blockers, although
