摘要:
A radical scavenger in accordance with the present invention comprises, as an effective ingredient, a phenylenediamine derivative or a pharmacologically acceptable salt thereof expressed by the following formula 1: ##STR1## wherein R.sub.1 represents a lower alkyl group; and each of R.sub.2 and R.sub.3 represents a hydrogen atom, an alkyl group having 1-10 carbon atoms, an alkenyl group having 1-10 carbon atoms, or benzyl group.The phenylenediamine derivative above mentioned, as a radical scavenger, has a lipid peroxidation inhibitory activity so as to be available for inhibiting brain infarction or brain edema.
摘要:
A benzamide derivative or a salt thereof expressed by the following formula 1: ##STR1## wherein R.sub.1 is hydrogen atom or a lower alkyl group; R.sub.2 is a benzyl or an alkenyl group; andn is an integer of 1 to 6.The benzamide derivative or a salt thereof has an anti-ulcer effect or an antibacterial activity against Hedicobacter pyroli, and has also high safety to be available for prevention or cure of ulcers.
