DSIP is a functional bioactive peptide widely used in life science research. It is mainly applied in pre-clinical experiments related to sleep rhythm regulation, helping modulate normal sleep-wake cycles and improve delta-wave activity. In neuroendocrine research, DSIP exhibits regulatory effects on stress-related hormone secretion, assisting in the study of body stress feedback mechanisms. Additionally, it possesses notable antioxidant and neuroprotective properties, delivers mild analgesic performance in experimental models, and contributes to maintaining central nervous system homeostasis.
