DOI (hydrochloride)

DOI hydrochloride is a serotonin 5-HT_2A/_2C receptor agonist with K_i values of 0.7 nM, 2.4 nM and 20 nM for h5-HT_2A, h5-HT_2C and h5-HT_2B receptors, respectively. DOI hydrochloride can across the blood-brain barrier. DOI hydrochloride increases head twitches in mice^[1][2][3]. In Vitro: DOI hydrochloride (10 μM; for 45 min) causes a massive increase in adhesion with 99% of the cells staying adherent compared to only 42% of untreated Hu2AAB1 cells^[5].
In Vivo: DOI hydrochloride (0.3-10 mg/kg; i.p.; single dose) produces an increase in mean head twitches at 3 mg/kg in Wild type (WT) ICR (CD-1) KO mice. Lower doses produces non-significant increases in head twitches, while a higher dose of 10 mg/kg produces increased variability yet a significant increase in mean head twitches^[3].
DOI (0.35-0.7 mmol/kg; sc) significantly increases waking and light sleep and reduces slow wave sleep, rapid-eye-movement (REM) sleep, and the number of REM periods in Male Wistar rats weighing 350-400 g^[4].
