[Synthesis, isomery, and hypotensive activity of thiethane-containing ylidenehydrazides of uracilylacetic acid].

: Using reaction of hydrazide 2-[6-methyl-1-(thiethane3-yl)uracil-3-yl]acetic acid with arylaldehydes and acetophenone derivatives were obtained acylhydrazones, which exist in DMSO solution as a mixture of two stereoisomers of a E(C=N)-isomer for due to hindered internal rotation around the hydrazide bond. It was revealed that the synthesized compounds exhibit antihypertensive activity.
