LP-211 is a selective and blood-brain barrier penetrant 5-HT7 receptor agonist, with a Ki of 0.58 nM, with high selectivity over 5-HT1A receptor (Ki, 188 nM) and D2 receptor (Ki, 142 nM).

LP-211 is a selective 5-HT7 receptor agonist, with a Ki of 0.58 nM, 324- and 245-fold selectivity over 5-HT1A receptor (Ki, 188 nM) and D2 receptor (Ki, 142 nM). LP-211 shows agonist properties with an EC50 of 0.6 μM[1].

LP-211 (10 mg/kg, i.p.) rapidly reaches the systemic circulation in the mouse, with mean Cmax of 0.76 ± 0.32 μg/mL at 30 min[1]. LP-211 (0.003-0.3 mg/kg, i.p.) significantly increases the micturition volume in a dose-dependent manner, and causes significant increases in voiding efficiency in spinal cord-injured (SCI) rats, and such effects can be completely reversed by SB-269970[2]. LP-211 (0.25 and 0.50 mg/kg i.p.) improves consolidation of chamber-shape memory in rats, resulting in significant novelty-induced hyperactivity and recognition[3].
