HIDE SMILES / InChI
MK-212 is a 5HT2C-receptor agonist. It displays selectivity for 5-HT2C over 5-HT2A (IC50 values are 0.028 and 0.42 uM for human 5-HT2C and 5-HT2A receptors expressed in HEK293 cells respectively). A dose-dependent the effect of 5HT2C-receptor agonist MK-212 on mouse behavior was demonstrated. Intraperitoneal injection of MK-212 in high doses (0.5 and 1.0 mg/kg) increased blood level of corticosterone in mice and reduced their motor activity. In low doses of 0.1 and 0.2 mg/kg, the agonist reduced anxiety, but had no effect on motor activity. It is hypothesized that low doses of MK-212 exhibited anxiolytic activity in mice.

Sample Use Guides

The effects of MK-212 (10, 20, and 40 mg, orally), a centrally acting serotonin (5-HT) receptor agonist and placebo, on serum cortisol, prolactin, and growth hormone levels were studied in eight healthy men over 3-hr. MK-212 produced a dose-related increase in serum cortisol levels, with the 20- and 40-mg doses producing significant elevations. Serum prolactin levels were significantly elevated only by the 40-mg dose.
Route of Administration: Oral
In Vitro Use Guide
MK-212 (1 x 10(-7)M -- 1 x 10(-5)M) produced dose-dependent contractions of guinea pig ileum, taenia coil and rat fundus strip.
