GR203040 is a high affinity, non-peptide tachykinin NK1 receptor antagonist.
GR203040 is a high affinity, non-peptide tachykinin NK1 receptor antagonist. GR203040 inhibits substance P binding to human NK1 receptors in CHO cells with a pKi or 10.3. The compound prevents emisis, and reduces bladder damage induced by radiation, cisplatin and cyclophosphamide. 11C-labeled GR203040 is used as a radioligand to image NK1 receptors in the CNS by PET scanning.

1. The effect of the tachykinin neurokinin1 (NK1) receptor antagonist GR203040 on cyclophosphamide (CYP)-induced bladder damage was investigated in rats and ferrets. The 5-hydroxytryptamine3 receptor antagonists ondansetron and granisetron were similarly examined in ferrets. 2. In the rat, GR203040 (10

It has been demonstrated recently that antagonists of the tachykinin NK1 receptor, specifically CP-99,994 and GR203040, possess anti-emetic activity in a range of species. To optimise this activity, a series of analogues based around the structure of GR203040 have been
M Bergström et al.
Neuropharmacology, 39(4), 664-670 (2000-03-23)
Two high affinity and selective NK1-receptor antagonists, GR203040 and GR205171, were labelled with 11C and used in a series of experiments in rhesus monkeys. The purpose of these studies was to evaluate the brain uptake pattern and to explore the

1. Following our earlier observations that the tachykinin NK1 receptor antagonist CP-99,994 is an effective anti-emetic in ferrets, we have examined the anti-emetic effects of a more potent and novel NK1 receptor antagonist, GR203040, against various emetic stimuli in the
P Ward et al.
Journal of medicinal chemistry, 38(26), 4985-4992 (1995-12-22)
The antiemetic, pharmacokinetic, and metabolic profile of CP-99,994, a potent NK1 receptor antagonist, has been carefully evaluated. As a result we began a medicinal chemistry program which initially identified a 3-furanyl analogue (6) with improved antiemetic potency and a methyl
