Application

Piclamilasthas been used as a phosphodiesterase-4 (PDE4) inhibitor to treat cultures at the indicated time points after blast exposure.

Biochem/physiol Actions

Piclamilast is a potent and selective cyclic AMP phosphodiesterase-4 inhibitor that exhibits equal, high affinity for both the PDE4 high- and low-affinity rolipram binding states (HARBS and LARBS). Recent studies shown that piclamilast inhibits Trypanosoma brucei PDEB1 (TbrPDEB1) and TbrPDEB2.
Piclamilast is also known as N-(3,5-dichloropyrid-4-yl)-3-cyclopentyloxy-4-methoxybenzamide. Piclamilast regulates the cAMP (cyclic adenosine monophosphate) signaling pathway. It increases the retinoid-dependent transactivation and the degradation of retinoic acid receptor α (RARα).

Phosphodiesterases (PDEs) are a family of enzymes that hydrolyze cyclic nucleotides to render them biologically inactive. As such, these enzymes are critical regulators of signal transduction pathways that use cyclic nucleotides as second messengers. PDE4 is one such member that

Phosphodiesterase (PDE) 4 inhibitors are potent anti-inflammatory drugs with antihypertensive properties, and their therapeutic role in bronchopulmonary dysplasia (BPD) is still controversial. We studied the role of PDE4 inhibition with piclamilast on normal lung development and its therapeutic value on

Phosphodiesterase (PDE) IV inhibitors have been reported to possess potent anti-inflammatory activities through enhancement of cAMP. In this study, the immunopharmacological effect of PDE IV inhibitor (RP73401) was further carefully evaluated. RP73401 strongly blocked the production of tumor necrosis factor

Phosphodiesterase-4 (PDE4) inhibitors may offer novel therapeutic strategies in respiratory diseases, including asthma and chronic obstructive pulmonary disease. Therefore, selective PDE4 inhibitors may also provide a therapeutic option for very pre-term infants with bronchopulmonary dysplasia (BPD). The anti-inflammatory effect of

Discover Bioactive Small Molecules for Cyclic Nucleotides

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
