認められた。Experimental Results Similar to known antihypertensive mercaptoacyl amino acids, the compound of the present invention suppressed angiotensin pressor response when orally administered to unanesthetized rats, and this was due to its mechanism of inhibiting angiotensin converting enzyme. The compounds of the present invention are derivatives of mercaptoacyl amino acids, and when equimolar amounts of these compounds were orally administered and their angiotensin pressor response inhibitory effects were compared, the compounds of the present invention were well absorbed into the gastrointestinal wall and were gradually cleaved. As a result, it has a longer-lasting effect and has an advantage as an antihypertensive agent.
