Abstract
The present invention provides a variety of compounds having a CaSR agonist activity which possesses a superior kokumi-imparting function, and more particularly provides a kokumi-imparting composition, which contains the foregoing compound, and/or another substance having a CaSR agonist activity, in combination. The present invention also provides a kokumi-imparting composition which includes a lanthionine derivative and/or another substance having a CaSR agonist activity.
Claims11
A compound having a structure represented by the following general formula (I), or an edible salt thereof:
- (I)
- wherein R1 and R2 each independently represent a hydrogen atom or a lower alkyl group having 1 to 3 carbon atoms;
- A represents a methylene group or an oxy group;
- and
- X represents an alkylene group having 1 to 5 carbon atoms, provided that one of the methylene groups present in the alkylene group may be substituted with a thio group, a disulfide group, an oxy group, an imino group or an alkyl-imino group having 1 to 3 carbon atoms and that the alkylene group may further be substituted with 1 to 6 alkyl groups each having 1 to 3 carbon atoms.
A compound having a structure represented by the following general formula (IA), or a chemically acceptable salt thereof:
- (IA)
- wherein R1′ and R2′ each independently represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms;
- R3′ represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a benzyl group, or a 9-fluorenylmethyl group;
- R4′ represents a t-butoxycarbonyl group, a benzyloxycarbonyl group, or a 9-fluorenylmethyloxycarbonyl group;
- R5′ represents a hydroxyl group, an alkoxy group having 1 to 4 carbon atoms, a benzyloxy group, an amino group (—NH2) or an alkylamino group having 1 to 3 carbon atoms;
- A represents a methylene group or an oxy group;
- and
- X represents an alkylene group having 1 to 5 carbon atoms, provided that one of the methylene groups present in the alkylene group may be substituted with a thio group, a disulfide group, an oxy group, an imino group or an alkyl-imino group having 1 to 3 carbon atoms and that the alkylene group may further be substituted with 1 to 6 alkyl groups each having 1 to 3 carbon atoms.
