| Description | Piclamilast (RP 73401) is a PDE4 inhibitor. |
| Targets&IC50 | PDE4:16 nM (pig aorta), PDE2:40 μM, PDE3:>100 μM, PDE5:14 μM, PDE1:>100 μM, PDE4:2 nM (eosinophil soluble) |
| In vitro | Piclamilast pre-treatment significantly inhibited the changes in 23 genes via mechanisms involving AP-1 activation and c-Jun phosphorylation at Ser63[1]. The IC50s for Piclamilast was 16 nM and 2 nM in pig aorta and eosinophil soluble, respectively. Piclamilast exhibited IC50 values >100 μM, 40 μM, >100 μM, 14 μM for PDE1, PDE2, PDE3 and PDE5. Respectively[4]. |
| In vivo | Initial in vivo studies conducted in severe combined immunodeficiency mice transplanted with NB4 leukemia cells indicate that the enhancing effect of piclamilast on ATRA-induced myeloid maturation translates into a therapeutic benefit[2]. |
