Mechanism of Action # The mechanism of action of DSIP remains incompletely understood, which has been described as a still unresolved riddle in the scientific literature.

Analgesic and Anticonvulsant Properties # In animal studies, DSIP has demonstrated analgesic properties when administered intracerebroventricularly or intracisternally, with a potent antinociceptive effect in mice.

This has led to interest in DSIP as a potential adaptogenic agent, though clinical evidence remains limited.
