A yeast extract or yeast-derived bioactive peptide having an activity of selectively inhibiting reuptake of serotonin and norepinephrine, which can be effectively used in preventing or treating various diseases related to reuptake of serotonin and norepinephrine, especially depression, anxiety, stress, fatigue and obesity is provided. Also, a yeast extract or yeast-derived bioactive peptide having activities as an anti-stress agent, an anti-fatigue agent, premenstrual syndrome (PMS) and menstrual pain relaxants, and a brain-neurotrophic factor, and a method for preparing the bioactive peptide is provided. The yeast extract or yeast-derived bioactive peptide is effective in relieving stress, nervousness, anxiety, tension, insomnia, fatigue, and imbalance in the autonomic nerve regulation. Therefore, the yeast extract or yeast-derived bioactive peptide is available as an anti-depression agent, an anti-anxiety agent, an anti-stress agent, an anti-fatigue agent, an anti-obesity agent, premenstrual syndrome and menstrual pain relaxants, a brain-neurotrophin, and a source of active foods having these activities.

Method for selectively inhibiting reuptake of serotonin and norepinephrine using yeast extract

The present invention relates to isothiazolone-containing compositions comprising a) 3-isothiazolone compounds; b) a metal nitrate; c) magnesium chloride; d) at least one compound selected from the group consisting of iodic acid, periodic acid, an iodate salt, and a periodate salt; e) chlorite salts; and f) solvents. The invention further provides a method for stabilizing isothiazolone-containing compositions by inhibiting precipitation of by-products formed during production and precipitation of the compounds formed during storage. The compositions of the invention are useful for suppressing the growth of microorganisms.
