| Bioactivity | LEO 39652 is a dual-soft PDE4 inhibitor with IC50s of 1.2 nM, 1.2 nM, 3.0 nM and 3.8 nM for PDE4A, PDE4B, PDE4C and PDE4D, respectively. LEO 39652 also inhibits TNF-α with an IC50 value of 6.0 nM. LEO 39652 is used for topical research of Atopic dermatitis (AD) [1]. | ||||||||||||
| Invitro | LEO 39652 shows unbound in vitro potency when measured as LPS induced TNF-α release in human peripheral blood mononuclear cells (PBMC), incubated in serum free medium. LEO 39652 shows a relatively high binding to human serum albumin[2]. | ||||||||||||
| In Vivo | LEO 39652 is inactivated both in blood and liver (dual-soft) while stabled in the skin[1].Pharmacokinetic AnalysisLEO 39652 exhibits total clearance (rats 930, minipigs 200 and monkey 300 mL/min/kg) and ratio to total AUC (rats 4, minipigs 6 and monkey 6 %) following intravenous administration (rats 0.075, minipigs 0.5 and monkeys 2.0 mg/kg)[1].
