Enoximone_product_DataBase

Bioactivity

Enoximone is an inotropic vasodilating agent and a selective and orally active phosphodiesterase III (PDE3) inhibitor with an IC50 of 5.9 μM. Enoximone induces vasodilatation and increases intracellular levels of cAMP by inhibiting cGMP-inhibited PDE. Enoximone also exhibits PDE4 inhibitory effect with an IC50 of 21.1 μM for myocardial PDE4A. Enoximone has the potential for congestive heart failure research and has bronchodilatory, antiasthma and anti-inflammatory effects[1][2][3].

Invitro

In vitro, 10 μM Enoximone-treated bronchoalveolar lavage (BAL) eosinophils induced by IL-33 treatment shows significantly lower CD11b expression when compared with diluent-treated BAL eosinophils[1].

In Vivo

Topical Enoximone (25 μg; intratracheal route) abrogates house dust mite (HDM)-induced allergic airway inflammation[1].The Enoximone-treated (25 μg; for 5 days) HDM-exposed mice shows significant reductions in inflammatory cell numbers including eosinophils, macrophages, neutrophils, ILC2s, and T cells, indicating that Enoximone treatment reduces airway inflammation[1].
