Arotinolol is a nonselective α/β-adrenergic receptor blocker and a vasodilating β-blocker. Arotinolol also shows potency for inhibiting the binding of the radioligand 125I-ICYP to 5HT1B-serotonergic receptor sites. It is an antihypertensive agent.
PCS1055 dihydrochloride is an effective, selective, and competitive muscarinic M4 receptor antagonist (IC50: 18.1 nM and a Kd: 5.72 nM). PCS1055 dihydrochloride is also a potent AChE inhibitor (IC50 s: 22 nM and 120 nM for electric eel and human AChE, res
PK14105 has been evaluated biologically as a potential radioligand for positron emission tomography (PET) studies targeting peripheral benzodiazepine binding sites (PBBS) receptors. When administered to rats with unilaterally lesioned striata, PK14105 was observed to quickly cross the blood-brain barrier, displaying significant radioactivity retention in the lesioned striatum, in contrast to the unlesioned striatum or cerebellar vermis. Additionally, PK14105 has the capability to inhibit receptor ligands, calcium channel ligands, and co-transporters in all salivary glands.
SB 224289 is a selective antagonist of 5-HT1B receptor with pKi of 8.2. It is a centrally active following oral administration in vivo. SB 224289 displays 60-fold selectivity over 5-HT1D, 5-HT1A, 5-HT1E, 5-HT1F, 5-HT2A and 5-HT2C receptors in radioligand
GSK-215083 is a PET radioligand for the 5-HT6 receptor. GSK 215083 is a quinoline based compounds and acts by antagonising the 5-HT6 receptor. GSK-215083 binds to receptors 5-hydroxytrypamine-6 (5HT6) in the striatum and 5-hydroxytryptamine-2A (5HT2A) in
