Biochem/physiol Actions

SB-204070 is a highly potent and specific antagonist of 4-HT4 receptor. It inhibits cholinergic and noncholinergic transmission and blocks the contractions of proximal colon in guinea pigs and relaxation of human colon circular smooth muscle.
Selective 5-HT4 serotonin receptor antagonist.

5-HT4 receptors mediate relaxation of human colon circular muscle. However, after 5-HT4 receptor blockade (SB 204070 10 nM), 5-HT still induced a relaxation (pEC50 6.3). 5-HT4 receptors were sufficiently blocked, as the curves to 5-HT obtained in the presence of...

The 5-HT4 receptor is a member of the seven transmembrane spanning G-protein-coupled family of receptors. The receptor is positively coupled to adenylate cyclase and exists in two isoforms (5-HT4S and 5-HT4L) that differ in the length and sequence of their...

The recently identified C-terminal splice variant of the human 5-HT(4) receptor, the h5-HT(4(d)) receptor, was stably expressed in a CHO cell line at 493+/-25 fmol mg(-1) protein. We analysed its pharmacological properties by measuring binding affinities and 5-HT(4) ligand-induced cyclic...
