PROBLEM TO BE SOLVED: To provide a β amyloid production inhibitor comprising as an active ingredient a compound having a completely different skeleton from a compound that has been reported to have a β amyloid production inhibitory action so far. The following formula (I): [Chemical 1] Wherein R 1 represents a hydrogen atom, a C 2-6 -alkenyl group, a carboxymethyl group, a C 1-6 -alkoxy-carbonylmethyl group or a 2-morpholinoethyl group; R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are the same or different and are a hydrogen atom, a hydroxyl group, a C 1-6 -alkyl group, a C 2-6 -alkenyl group, a C 1-6 -alkoxy. Represents a group, a C 2-6 -alkenyloxy group or a carboxyl group.) (Beta) amyloid production inhibitor containing the compound shown by these, its prodrug, or those pharmacologically acceptable salts. [Selection figure] None |
