Target Validation Information
TTD ID	T02752
Target Name	C-C chemokine receptor type 3 (CCR3)
Type of Target	Discontinued
Drug Potency against Target		Drug Info	IC50 = 0.009 uM	[4]
	YM-344031	Drug Info	IC50 = 3 nM	[3]
		Drug Info	IC50 = 2400 nM	[1]
Action against Disease Model		Drug Info	Chemotactic activity was significantly increased by an eosinophil chemoattractant in all asthmatic groups relative to healthy subjects (p < 0.05) and was significantly inhibitedby CAT-213 (100 nM) in subjects with moderate and severe asthma, with median inhibition of 52% (p < 0.05), 78% (p < 0.0001), and 86% (p < 0.0001), respectively, in samples representing stable-moderate, unstable-moderate, and severe asthma.
