Description

Lirimilast (BAY 19-8004) is a potent, selective and orally active phosphodiesterase-4 (PDE4) inhibitor with an IC50 value of 49 nM. Lirimilast can be used for the treatment of asthma or chronic obstructive pulmonary disease (COPD). Lirimilast has potently anti-inflammatory properties[1][2].

IC50 & Target

PDE4

42 nM (IC50)

In Vitro

In PDE4 assays Lirimilast (BAY 19-8004) is reported to be 5-fold more potent than Cilomilast and equipotent with CDP-840 using freshly prepared PDE4 from human PMNL[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Since Lirimilast (BAY 19-8004) is orally active in the guinea-pig at 3 mg/kg and, more critically, in primates at 0.1 mg/kg/day it appears to have a good therapeutic ratio. In addition Lirimilast is found to be 3-fold more potent than Cilomilast when compared in a rat model of lung neutrophilic inflammation[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
