General description

Oleamide is a lipid or a brain fatty acid, that is found in the CSF (cerebrospinal fluid). It is originally obtained from the cerebrospinal fluid of cats, that are sleep-deprived.

Application

Oleamide has been used as a supplement in glucose and galactose media to prevent the rescue of galactose-induced Leigh syndrome (LS).

Biochem/physiol Actions

Oleamide has the ability to stimulate sleep. It possess several properties, like cannabinoid-like activity. Oleamide can also disable the communication, facilitated by gap junction between rat glial cells.
Sleep-inducing brain lipid, which allosterically modulates GABAA receptors and potentiates 5-HT7 serotonin receptor responses. Selective endogenous agonist of rat and human CB1 cannabinoid receptor.

The central nervous system control of food intake has been extensively studied, hence, several neurotransmitter systems regulating this function are now clearly identified, for example, the endocannabinoid and serotoninergic systems. The former stimulates feeding while the latter inhibits it. Oleamide

Anandamide and oleamide, induce sleep when administered acutely, via the CB1 receptor. Their subchronic administration must be tested to demonstrate the absence of tolerance to this effect, and that the sudden withdrawal of these endocannabinoids (eCBs) does not affect sleep

Oligolysine-based cationic lipid derivatives were synthesized for delivery of siRNA, and formulated into cationic liposomes. Among various oligolysine-based lipid derivatives differing in lysine residue number and lipid moiety, trilysinoyl oleylamide (TLO)-based liposomes (TLOL) showed the highest delivery efficiency combined with
