RO-20-1724 is a potent inhibitor of Phosphodiesterase 4 (PDE4) originally developed by Roche. It showed some promise as a potential treatment for psoriasis, but it was discontinued when it could not match the efficacy of existing treatments. RO-20-1724 was also investigated as a potential treatment for asthma and septic shock.

Sample Use Guides

In Vivo Use Guide
In a clinical trial for the treatment of psoriasis, a 1% RO-20-1724 cream was applied 4 times a day for 4 weeks to affected areas. RO-20-1724 was not as effective as intensive occlusive treatment of psoriatic lesions with 0.025% triamcinolone acetonide
Route of Administration: Topical
In Vitro Use Guide
Curator's Comment: referenced study was conducted in rat
Aortic vascular smooth muscle (VSM) cells were harvested from enzymatically dissociated rat thoracic aorta. Cells were stimulated by incubation with interleukin-lp (IL-10) at different concentrations for varying periods of time up to 48 h, with and without RO-20-1724. Nitric Oxide Synthase activity was assessed by measurement of nitrite production. RO-20-1724 had no detectable effect on nitrite levels in the absence of IL-lp but enhanced the production of nitrite in response to IL-Il in a dose-dependent manner.
