Bioactivity | RS 67333 hydrochloride is a potent and selective 5-HT4 receptor (5-HT4R) partial agonist with a pKi of 8.7 in guinea-pig striatum. RS 67333 hydrochloride exhibits lower affinities at several other receptors including 5-HT1A, 5-HT1D, 5-HT2A, 5-HT2C, dopamine D1, D2 and muscarinic M1-M3 receptors. RS 67333 hydrochloride has neuroprotective effects, and can be used for Alzheimer's disease research[1]. |
Invitro | RS 67333 hydrochloride does exhibit affinities for the sigma 1 (pKi = 8.9) and sigma 2 (pKi = 8.0) binding sites. At the 5-HT4 receptor mediating relaxation of the carbachol-precontracted oesophagus, RS 67333 hydrochloride acts as a potent (pEC50 of 8.4), partial agonists (intrinsic activities, with respect to 5-HT is 0.5) with respect to 5-HT[1]. |
