Since serotonin has been shown to influence platelet biology and atherothrombosis, we sought to investigate the association of platelet serotonin transporter number, binding affinity, and uptake kinetics with platelet aggregation.
Transporter-dependent serotonin uptake rate was determined (Vmax), as were serotonin transporter number (Bmax) and binding affinity (Kd) using 3H paroxetine binding in a homologous displacement assay, nonlinear regression and validated algorithms for kinetic modelling.
Of note, we found that SZRD increases sleep activity and exhibits binding affinity for serotonin receptors.
A lot of dopamine and serotonin antagonists reveal non-selective binding affinity against these two receptors because the antagonists share structurally common features originated from conserved residues of binding site of the aminergic receptor family.
At the global metabolomics levels, SZRD can increase sleep activity and exhibit binding affinity for serotonin receptors in a model of insomnia drosophila [ 19].
A series of new tetrahydroprotoberberine (THPB) derivatives were designed, synthesized, and tested for their binding affinity towards dopamine (D1 and D2) and serotonin (5-HT1A and 5-HT2A) receptors.
TD-8954 (4, also developed by Theravance) is highly selective for the 5-HT4c receptor, with the binding affinity 2000-fold sthanger than for the other 5-HT receptors and non-serotonin receptors.
This compound exhibited a binding affinity value of 0.094 nM toward human 5-HT4R and a high selectivity over other serotonin receptor subtypes (5-HTR).
Antipsychotic-induced weight gain has been proposed as due to antagonistic effects at, among the others, the histamine H1 [ 54, 55], serotonin 5-HT2C [ 56] and dopamine D2 [ 57] receptors; while the diabetogenic effect has been correlated with binding affinity to H1 [ 55], 5-HT2C and muscarinic acetylcholine receptors [ 34].
f Mutant LoNA showed diminished binding affinity to NCL.
Even so, the low affinity binders can undergo in vitro affinity maturation to improve their binding affinity and specificity5,39,42.
