摘要:
The present invention discloses the use, in the manufacture of a preventive and therapeutic drug of a brain disease, of a compound represented by formula (1): CH2═CH—CH2—S(O)n—R (1) [wherein R represents a hydrogen atom, an alkyl group, an alkenyl group, a substituted alkyl group, a substituted alkenyl group, an alkylthio group, an alkenylthio group, a phenyl group, a substituted phenyl group, a heterocyclic group, or a group derived from an amino acid or an oligopeptide by deletion of one hydrogen atom, and which group may have a protective group; and n is 0, 1, or 2], a glycoside thereof, or a salt of the compound or the glycoside. The drug of the present invention for ameliorating brain diseases, inhibiting reduction of brain neurons and promoting branching of neurites, is useful for the prevention and treatment of brain diseases such as dementia in association with degeneration and sloughing of brain neurons.
