Pharmacological characterization of hetrombopag, a novel orally active human thrombopoietin receptor agonist

SR146131: a new potent, orally active, and selective nonpeptide cholecystokinin subtype 1 receptor agonist. II. In vivo pharmacological characterization.

SR146131 is a potent and selective agonist at cholecystokinin subtype 1 (CCK1) receptors in vitro. The present study evaluates the activity of the compound in vivo. SR146131 completely inhibited gastric and gallbladder emptying in mice (ED50 of 66 and 2.7 micrograms/kg p.o., respectively). SR146131 dose dependently reduced food intake in fasted rats (from 0.1 mg/kg p.o.), in nonfasted rats in w...

Pharmacological characterization of ZD6021: a novel, orally active antagonist of the tachykinin receptors.

The tachykinins, substance P, neurokinin A, and neurokinin B, have been implicated in many diseases. The present study evaluated the pharmacological properties of a novel tachykinin antagonist ZD6021 [3-cyano-N-((2S)-2-(3,4-dichlorophenyl)-4-[4-[2-(methyl-(S)-sulfinyl)-phenyl]piperidino]butyl)-N-methyl-]-napthamide]. The affinity (K(i)) of ZD6021 for the cloned human neurokinin (NK)1, NK2, and ...

Biochemical and pharmacological characterization of SSR69071, a novel orally active elastase inhibitor

Pharmacological profile of ZD1611, a novel, orally active endothelin ETA receptor antagonist.

The endothelins (ETs), potent vasoconstrictor peptides, have been implicated in the pathogenesis of various cardiovascular disorders. In the present study, we describe the novel, potent, orally active, selective ET(A) receptor antagonist ZD1611 [3-(4-[3-(3-methoxy-5-methylpyrazin-2-ylsulfamoyl)-2-pyridyl ]phenyl)- 2,2-dimethylpropanoic acid]. ZD1611 competitively inhibited (125)I-labeled ET-1 b...

In Vitro Pharmacological Characterization of a Novel Selective 7 Neuronal Nicotinic Acetylcholine Receptor Agonist ABT-107

Enhancement of 7 nicotinic acetylcholine receptor (nAChR) activity is considered a therapeutic approach for ameliorating cognitive deficits present in Alzheimer’s disease and schizophrenia. In this study, we describe the in vitro profile of a novel selective 7 nAChR agonist, 5-(6-[(3R)-1-azabicyclo[2,2,2]oct-3-yloxy]pyridazin-3-yl)-1H-indole (ABT-107). ABT-107 displayed high affinity binding to...
