rs67333

RS 67333 hydrochloride (RO5203648) is a potent, selective partial agonist of the 5-HT4 receptor (5-HT4R) with a pKi value of 8.7 in guinea-pig striatum. It demonstrates lower binding affinities for other receptors, including 5-HT1A, 5-HT1D, 5-HT2A, 5-HT2C, dopamine D1 and D2, and muscarinic M1-M3 receptors. Notably, RS 67333 hydrochloride exhibits neuroprotective properties, rendering it useful in Alzheimer's disease research.

RS-67333 is a selective and efficient partial agonist of the 5-HT4 receptor (5-HT4R) with neuroprotective effects, useful in preventing amyloid deposition and behavioral deficits in the 5XFAD mouse model of Alzheimer's disease.
