Other Information:

Sold with the permission of Astellas Pharma Inc.

Chemical Name: 5,6-Dihydro-2,3-dimethoxy-6,6-dimethylbenz[7,8]indolizi no[2,3-b]quinoxaline

Biological Activity:

Novel, selective inhibitor of interleukin-5 (IL-5) binding to its receptor (IC50 = 0.45-1 μM). Inhibits IL-5-prolonged eosinophil survival and IL-5-induced tyrosine phosphorylation of Jak2 without inhibiting GM-CSF-mediated effects. In vivo, inhibits antigen-induced eosinophil and lymphocyte recruitment in rat airways, without affecting peripheral blood or bone marrow leukocytes.
