PDE4-IN-4 is a compound acting as both a potent M3 antagonist (p IC 50 = 10.2) and a PDE4 inhibitor (p IC 50 = 8.8), designed for inhalation-based treatment of pulmonary diseases.
CBS-3595 is a potent and dual Inhibitor of p38α MAPK PDE-4 with a superior profile regarding its anti-inflammatory effects. CBS-3595 features moderate inhibition of p38α MAPK and PDE-4 in the higher nanomolar range in combination with excellent kinetic pr
PDE4-IN-3 is a newly developed oral compound that acts as a potent inhibitor of the enzyme phosphodiesterase 4 (PDE4), displaying a high affinity for inhibition with an IC50 value of 4.2 nM.
CC-1088 is an analog of thalidomide with potential antineoplastic activity that belongs to the functional class of agents called selective cytokine inhibitory drugs (SelCIDs). SelCIDs inhibit phosphodiesterase-4 (PDE 4), an enzyme involved in tumor necrosis factor alpha (TNF alpha) production. CC-1088 inhibits production of the cytokines vascular endothelial growth factor (VEGF) (a pro-angiogenic factor) and interleukin-6 (IL-6).
(E Z)-Ensifentrine is a potent and selective PDE3 4 inhibitor. (E Z)-Ensifentrine acts as a long-acting inhibitor of the phosphodiesterase enzymes PDE-3 and PDE-4, producing both bronchodilator and antiinflammatory effects. It is being developed by Verona Pharma as a potential treatment for asthma and hay fever, and is currently in clinical trials.
Cipamfylline is a xanthine, a theophylline analogue, and is a potent and selective inhibitor of phosphodiesterase type 4 (PDE-4). Cipamfylline was tested in patients with a diagnosis of atopic dermatitis and in two human models of acute and chronic irritant contact dermatitis. The outcome of the study revealed that cipamfylline was more effective than vehicle in treating atopic dermatitis, but less effective than a group II steroid, hydrocortisone-17-butyrate both in the treatment of atopic dermatitis and irritant contact dermatitis. The absorption of cipamfylline and the subsequent systemic exposure might be the reason why further clinical studies with higher doses of cipamfylline have not been published.
