Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/23827726

AZD-1981, developed by AstraZeneca, is a potent (binding IC50 of 4nM), fully reversible, functionally non-competitive antagonist of human CRTh2. It blocks agonist-induced human eosinophil CD11b expression, shape change (including in whole blood), and chemotaxis as well as an basophil shape change and Th2-cell chemotaxis at IC50's of 8.5-50nM. Potency is similar across species as is plasma protein binding (~97%). AZD-1981 is a weak (10s of μM) inhibitor in vitro of CYP2C9, OATP1B1 and UGT1A1 as well as an inducer of CYP3A4. AZD-1981 was well tolerated and no safety concerns were identified.There was no beneficial clinical effect of AZD-1981, at a dose of 1000 mg twice daily for 4 weeks, in patients with moderate to severe COPD. AZD-1981 has being discontinued for asthma and chronic obstructive pulmonary disease. AstraZeneca is collaborating with Johns Hopkins University for the development of AZD-1981 in the treatment of chronic idiopathic urticaria. It is in phase II clinicals studies for the treatment of Urticaria.

CNS Activity

Curator's Comment: AZD1981 has low CNS penetration and, thus, is probably not suitable for a CNS indication

Sample Use Guides

In Vivo Use Guide
AZD-1981 has been administered orally in healthy volunteers (single oral dose up to 4,000 mg; multiple doses up to 2,000 mg twice daily [BID] for 2 wks), asthma or COPD patients (up to 100 mg, BID for 4 wks), and asthmatics (up to 400 mg BID for 12 wks).
Route of Administration: Oral
AZD-1981 inhibits DK-PGD2-induced CD11b expression in human eosinophils with IC50 of 10 nM.
