Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/16168647 | https://www.ncbi.nlm.nih.gov/pubmed/24904269

CDP 840 hydrochloride is a potent and selective inhibitor of phosphodiesterase 4 (PDE4). This compound competitively inhibits all PDE4 isoenzymes, which in turn prevents the cleavage of phosphodiester bonds found in secondary messenger molecules. CDP-840 had been in phase II clinical trials for the treatment of asthma. However, CDP840 did not lead to changes in baseline forced expiratory volume in one second (FEV1) as compared to placebo. CDP 840 research has been discontinued.

Sample Use Guides

Patients were allocated either 15 mg b.i.d. CDP840 or placebo for a period of 9.5 days.
Route of Administration: Oral
Incubations with microsomes prepared from different species were typically conducted under linear conditions with 80 mkM CDP-840 and 0.5 mg of microsomal protein in the presence of an NADPH-generating system. Incubations (0.5 ml) were conducted for 30 min at 37°C and were quenched by the addition of an equal volume of acetonitrile.
