PDE4catalyticdomain 60nM(IC50) | PDE4B1 31nM(IC50) | PDE4D7 47nM(IC50) |
FCPR03 is a potent and selective phosphodiesterase 4 (PDE4) inhibitor with IC50 values of 60 nM, 31 nM and 47 nM for PDE4 catalytic domain, PDE4B1 and PDE4D7, respectively. FCPR03 displays at least 2100-fold selectivity over other PDEs (PDE1-3 and PDE5-11). FCPR03 has anti-inflammatory, neuroprotective and antidepressant-like effects[1][2].
FCPR03 (5-20 μM; 30 hours; HT-22 cells) treatment increases cell viability (oxygen-glucose deprivation (OGD)-induced) in a dose-dependent manner, and 10 μM FCPR03 shows significant protective effects[1].FCPR03 (20 μM; 30 hours; HT-22 cells) treatment protects against OGD-induced cellular apoptosis in both HT-22 cells and cortical neurons. The levels of mitochondrial membrane potential (MMP) and ROS are also restored by FCPR03[1].FCPR03 (20 μM; 30 hours; HT-22 cells) treatment increases the levels of phosphorylated AKT, glycogen synthase kinase-3β (GSK3β), and β-catenin[1].
FCPR03 (1.25-5 mg/kg; intraperitoneal injection; once; adult male Sprague-Dawley rats) treatment reduces the infarct volume and improves neurobehavioral outcomes in rats following MCAO. FCPR03 increases the levels of phosphorylated AKT, GSK3β and β-catenin within the ischemic penumbra of rats following cerebral ischemia-reperfusion[1].

Inhibition of PDE4 protects neurons against oxygen-glucose deprivation-induced endoplasmic reticulum stress through activation of the Nrf-2/HO-1 pathway
Redox Biol 2020 Jan;28:101342.PMID:31639651DOI:10.1016/j.redox.2019.101342.
Inhibition of phosphodiesterase 4 (PDE4) produces neuroprotective effects against cerebral ischemia. However, the involved mechanism remains unclear. Augmentation of endoplasmic reticulum (ER) stress promotes neuronal apoptosis, and excessive oxidative stress is an inducer of ER stress. The present study aimed to determine whether suppression of ER stress is involved in the protective effects of PDE4 inhibition against cerebral ischemia. We found that exposing HT-22 cells to oxygen-glucose deprivation (OGD) significantly activated ER stress, as evidenced by increased expression of the 78-kDa glucose-regulated protein (GRP78), phosphorylated eukaryotic translation-initiation factor 2α (eIF2α), and C/EBP-homologous protein (CHOP). Overexpression of PDE4B increased ER stress, while knocking down PDE4B or treatment with the PDE4 inhibitor, FCPR03, prevented OGD-induced ER stress in HT-22 cells. Furthermore, FCPR03 promoted the translocation of nuclear factor erythroid 2-related factor 2 (Nrf-2) from the cytoplasm to the nucleus. Importantly, the Nrf-2 inhibitor, ML385, blocked the inhibitory role of FCPR03 on OGD-induced ER stress. ML385 also abolished the protective role of FCPR03 in HT-22 cells subjected to OGD. Knocking down heme oxygenase-1 (HO-1), which is a target of Nrf-2, also blocked the protective role of FCPR03, enhanced the level of reactive oxygen species (ROS), and increased ER stress and cell death. We then found that FCPR03 or the antioxidant, N-Acetyl-l-cysteine, reduced oxidative stress in cells exposed to OGD. This effect was accompanied by increased cell viability and decreased ER stress. In primary cultured neurons, we found that FCPR03 reduced OGD-induced production of ROS and phosphorylation of eIF2α. The neuroprotective effect of FCPR03 against OGD in neurons was blocked by ML385. These results demonstrate that inhibition of PDE4 activates Nrf-2/HO-1, attenuates the production of ROS, and thereby attenuates ER stress in neurons exposed to OGD. Additionally, we conclude that FCPR03 may represent a promising therapeutic agent for the treatment of ER stress-related disorders.
FCPR03, a novel phosphodiesterase 4 inhibitor, alleviates cerebral ischemia/reperfusion injury through activation of the AKT/GSK3β/ β-catenin signaling pathway
Biochem Pharmacol 2019 May;163:234-249.PMID:30797872DOI:10.1016/j.bcp.2019.02.023.
Inhibition of phosphodiesterase 4 (PDE4) is a promising strategy for the treatment of ischemic stroke. However, the side effects of nausea and vomiting from the current PDE4 inhibitors have limited their clinical applications. FCPR03 is a novel PDE4 inhibitor with little emetic potential. This study aimed to investigate the effects of FCPR03 on neuronal injury after cerebral ischemia/reperfusion and the underlying signaling pathway. The effects of FCPR03 on cellular apoptosis, intracellular accumulation of reactive oxygen species (ROS), and mitochondrial membrane potential (MMP) were evaluated in HT-22 neuronal cells and cortical neurons exposed to oxygen-glucose deprivation (OGD). The impact of FCPR03 on brain injury, neurological scores and behavioral performance was investigated in rats subjected to middle cerebral artery occlusion (MCAO). The protein kinase B (AKT) inhibitor MK-2206 and β-catenin siRNA were used to investigate the underlying pathways. FCPR03 dose-dependently protected against OGD-induced cellular apoptosis in both HT-22 cells and cortical neurons. The levels of MMP and ROS were also restored by FCPR03. FCPR03 increased the levels of phosphorylated AKT, glycogen synthase kinase-3β (GSK3β), and β-catenin. Interestingly, the role of FCPR03 was reversed by MK-2206 and β-catenin siRNA. Consistently, FCPR03 reduced the infarct volume and improved neurobehavioral outcomes in rats following MCAO. Moreover, FCPR03 increased the levels of phosphorylated AKT, GSK3β and β-catenin within the ischemic penumbra of rats following cerebral ischemia-reperfusion. Taken together, FCPR03 has therapeutic potential in cerebral ischemia-reperfusion. The neuroprotective effects of FCPR03 are mediated through activation of the AKT/GSK3β/β-catenin pathway.
Inhibition of Phosphodiesterase 4 by FCPR03 Alleviates Chronic Unpredictable Mild Stress-Induced Depressive-Like Behaviors and Prevents Dendritic Spine Loss in Mice Hippocampi
Int J Neuropsychopharmacol 2019 Feb 1;22(2):143-156.PMID:30407503DOI:10.1093/ijnp/pyy092.
Background: Phosphodiesterase 4 is a promising target for developing novel antidepressants. However, prototype phosphodiesterase 4 inhibitors show severe side effects, including nausea and vomiting. N-Isopropyl-3-(cyclopropylmethoxy)-4-difluoromethoxy benzamide (FCPR03) is a novel phosphodiesterase 4 inhibitor with little emetic potential. In the present study, we investigated the inhibitory effect of FCPR03 on chronic unpredictable mild stress-induced, depressive-like behaviors in mice and explored the underlying mechanisms. Methods: The depression model of mice was established by chronic unpredictable mild stress. Forced swim test, tail suspension test, and sucrose preference test were used to assess depressive-like behaviors. Golgi-staining was utilized to analyze dendritic morphology and spine density. The level of cAMP was measured by enzyme-linked immnosorbent assay assay. Western blot was used to evaluate protein levels of phosphorylated cAMP-response element binding protein, protein kinase B, glycogen synthase kinase-3β, and brain derived neurotrophic factor in both hippocampus and prefrontal cortex. Postsynaptic density protein 95 and synapsin 1 were also detected by western blot in the hippocampi. Results: Treatment with FCPR03 (0.5-1.0 mg/kg, i.p.) increased consumption of sucrose in the sucrose preference test in mice exposed to chronic unpredictable mild stress. FCPR03 shortened the immobility time in forced swim test and tail suspension test without affecting locomotor activity. Furthermore, chronic unpredictable mild stress decreased the dendritic spine density and dendritic length in the hippocampus. This change was accompanied by decreased expression of postsynaptic density protein 95 and synapsin 1. Interestingly, FCPR03 prevented dendritic spine loss and increased synaptic protein levels. Moreover, the levels of cAMP, phosphorylated cAMP-response element binding protein, and brain derived neurotrophic factor were elevated in chronic unpredictable mild stress-challenged mice after treatment with FCPR03. In addition, FCPR03 also enhanced the phosphorylation of both protein kinase B and glycogen synthase kinase-3β in mice exposed to chronic unpredictable mild stress. Conclusion: The present study suggests that FCPR03 could prevent both depressive-like behaviors and spine loss induced by chronic unpredictable mild stress in the mice hippocampi.
Novel Phosphodiesterase 4 Inhibitor FCPR03 Alleviates Lipopolysaccharide-Induced Neuroinflammation by Regulation of the cAMP/PKA/CREB Signaling Pathway and NF- κ B Inhibition
J Pharmacol Exp Ther 2017 Jul;362(1):67-77.PMID:28450469DOI:10.1124/jpet.116.239608.
Overactivation of microglia contributes to the induction of neuroinflammation, which is highly involved in the pathology of many neurodegenerative diseases. Phosphodiesterase 4 (PDE4) represents a promising therapeutic target for anti-inflammation; however, the dose-limiting side effects, such as nausea and emesis, have impeded their clinic application. FCPR03, a novel selective PDE4 inhibitor synthesized in our laboratory, shows little or no emetic potency; however, the anti-inflammatory activities of FCPR03 in vitro and in vivo and the molecular mechanisms are still not clearly understood. This study was undertaken to delineate the anti-inflammatory effects of FCPR03 both in vitro and in vivo and explore whether these effects are regulated by PDE4-mediated signaling pathway. BV-2 microglial cells stimulated by lipopolysaccharide (LPS) and mice injected i.p. with LPS were established as in vitro and in vivo models of inflammation. Our results showed that FCPR03 dose dependently suppressed the production of tumor necrosis factor α, interleukin-1β, and iinterleukin-6 in BV-2 microglial cells treated with LPS. The role of FCPR03 in the production of proinflammatory factors was reversed by pretreatment with protein kinase A (PKA) inhibitor H89. In addition, FCPR03 reduced the levels of proinflammatory factors in the hippocampus and cortex of mice injected with LPS. Our results further demonstrated that FCPR03 effectively increased the production of cAMP, promoted cAMP response element binding protein (CREB) phosphorylation, and inhibited nuclear factor κB (NF-κB) activation both in vitro and in vivo. Our findings suggest that FCPR03 inhibits the neuroinflammatory response through the activation of cAMP/PKA/CREB signaling pathway and NF-κB inhibition.
Inhibition of Phosphodiesterase 4 by FCPR03 Alleviates Lipopolysaccharide-Induced Depressive-Like Behaviors in Mice: Involvement of p38 and JNK Signaling Pathways
Int J Mol Sci 2018 Feb 8;19(2):513.PMID:29419799DOI:10.3390/ijms19020513.
Inflammatory responses induced by peripheral administration of lipopolysaccharide (LPS) triggers depressive-like behavioral syndrome in rodents. Inhibition of phosphodiesterase 4 (PDE4) produces a robust anti-inflammatory effect in inflammatory cells. Unfortunately, archetypal PDE4 inhibitors cause intolerable gastrointestinal side-effects, such as vomiting and nausea. N-isopropyl-3-(cyclopropylmethoxy)-4-difluoromethoxy benzamide (FCPR03) is a novel, selective PDE4 inhibitor with little, or no, emetic potency. Our previous studies show that FCPR03 is effective in attenuating neuroinflammation in mice treated with LPS. However, whether FCPR03 could exert antidepressant-like effect induced by LPS is largely unknown. In the present study, mice injected intraperitoneally (i.p.) with LPS was established as an in vivo animal model of depression. The antidepressant-like activities of FCPR03 were evaluated using a tail suspension test, forced swimming test, and sucrose preference test. We demonstrated that administration of FCPR03 (1 mg/kg) produced antidepressant-like effects in mice challenged by LPS, as evidenced by decreases in the duration of immobility in the forced swim and tail suspension tests, while no significant changes in locomotor activity were observed. FCPR03 also increased sucrose preference in mice treated with LPS. In addition, treatment with FCPR03 abolished the downregulation of brain-derived neurotrophic factor induced by LPS and decreased the level of corticosterone in plasma. Meanwhile, periphery immune challenge by LPS induced enhanced phosphorylation of p38-mitogen activated protein kinase (p38) and c-Jun N-terminal kinase (JNK) in both the cerebral cortex and hippocampus in mice. Interestingly, treatment with FCPR03 significantly blocked the role of LPS and reduced the levels of phosphorylated p38 and JNK. Collectively, these results indicate that FCPR03 shows antidepressant-like effects in mice challenged by LPS, and the p38/JNK signaling pathway is possibly involved in this process. Our findings suggest that FCPR03 is a potential compound for the prevention or treatment of depression.
