Abstract
INTRODUCTION Phosphodiesterase 9 (PDE9) has been demonstrated as a potential target for neurological disorders and cardiovascular diseases, such as Alzheimer's disease and heart failure. For the last few years, a series of PDE9 inhibitors with structural diversities have been developed and patented by researchers and pharmaceutical companies, providing insights into first-in-class therapies of PDE9 drug candidates. AREA COVERED This review provides an overview of PDE9 inhibitors in patents from 2018 to the present. EXPERT OPINION Only a few of the current PDE9 inhibitors are highly selective over other PDEs, which limits their application in pharmacological and clinical research. The design and development of highly selective PDE9 inhibitors remain the top priority in future research. The advantages of targeting PDE9 rather than other PDEs in treating neurodegenerative diseases need to be explained thoroughly. Besides, application of PDE9 inhibitor-based combination therapies sheds light on treating diabetes and refractory heart diseases. Finally, PDE9 inhibitors should be further explored in clinical indications beyond neurological disorders and cardiovascular diseases.

Opportunities and perspectives of small molecular phosphodiesterase inhibitors in neurodegenerative diseases. Eur J Med Chem 2024; 271:116386. [PMID: 38614063 DOI: 10.1016/j.ejmech.2024.116386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/19/2024] [Accepted: 04/01/2024] [Indexed: 04/15/2024]
Abstract
Phosphodiesterase (PDE) is a superfamily of enzymes that are responsible for the hydrolysis of two second messengers: cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). PDE inhibition promotes the gene transcription by activating cAMP-response element binding protein (CREB), initiating gene transcription of brain-derived neurotrophic factor (BDNF). The procedure exerts neuroprotective profile, and motor and cognitive improving efficacy. From this point of view, PDE inhibition will provide a promising therapeutic strategy for treating neurodegenerative disorders. Herein, we summarized the PDE inhibitors that have entered the clinical trials or been discovered in recent five years. Well-designed clinical or preclinical investigations have confirmed the effectiveness of PDE inhibitors, such as decreasing Aβ oligomerization and tau phosphorylation, alleviating neuro-inflammation and oxidative stress, modulating neuronal plasticity and improving long-term cognitive impairment.

Abstract
Cyclic nucleotide phosphodiesterase 9 (PDE9), a specifically hydrolytic enzyme with the highest affinity for cyclic guanosine monophosphate (cGMP) among the phosphodiesterases family, plays a critical role in many biological processes. Consequently, the development of PDE9 inhibitors has received increasing attention in recent years, with several compounds undergoing clinical trials for the treatment of central nervous system (CNS) diseases such as Alzheimer's disease, schizophrenia, and psychotic disorders, as well as heart failure and sickle cell disease. This review analyzes the recent primary literatures and patents published from 2004 to 2023, focusing on the structure, pharmacophores, selectivity, and therapeutic potential of PDE9 inhibitors. It hoped to provide a comprehensive overview of the field's current state to inform the development of novel PDE9 inhibitors.

Abstract
Vascular dementia (VaD) is the second commonest type of dementia which lacks of efficient treatments currently. Neuroinflammation as a prominent pathological feature of VaD, is highly involved in the development of VaD. In order to verify the therapeutic potential of PDE1 inhibitors against VaD, the anti-neuroinflammation, memory and cognitive improvement were evaluated in vitro and in vivo by a potent and selective PDE1 inhibitor 4a. Also, the mechanism of 4a in ameliorating neuroinflammation and VaD was systematically explored. Furthermore, to optimize the drug-like properties of 4a, especially for metabolic stability, 15 derivatives were designed and synthesized. As a result, candidate 5f, with a potent IC50 value of 4.5 nmol/L against PDE1C, high selectivity over PDEs, and remarkable metabolic stability, efficiently ameliorated neuron degeneration, cognition and memory impairment in VaD mice model by suppressing NF-κB transcription regulation and activating cAMP/CREB axis. These results further identified PDE1 inhibition could serve as a new therapeutic strategy for treatment of VaD.

Abstract
Dipyridamole, apart from its well-known antiplatelet and phosphodiesterase inhibitory activities, is a promising old drug for the treatment of pulmonary fibrosis. However, dipyridamole shows poor pharmacokinetic properties with a half-life (T1/2) of 7 min in rat liver microsomes (RLM). To improve the metabolic stability of dipyridamole, a series of pyrimidopyrimidine derivatives have been designed with the assistance of molecular docking. Among all the twenty-four synthesized compounds, compound (S)-4h showed outstanding metabolic stability (T1/2 = 67 min) in RLM, with an IC50 of 332 nM against PDE5. Furthermore, some interesting structure–activity relationships (SAR) were explained with the assistance of molecular docking.

Abstract
Psoriasis is a common immune-mediated skin disorder manifesting in abnormal skin plaques, and phosphodiesterase 4 (PDE4) is an effective target for the treatment of inflammatory diseases such as psoriasis. Toddacoumalone is a natural PDE4 inhibitor with moderate potency and imperfect drug-like properties. To discover novel and potent PDE4 inhibitors with considerable druggability, a series of toddacoumalone derivatives were designed and synthesized, leading to the compound (2R,4S)-6-ethyl-2-(2-hydroxyethyl)-2,8-dimethyl-4-(2-methylprop-1-en-1-yl)-2,3,4,6-tetrahydro-5H-pyrano[3,2-c][1,8]naphthyridin-5-one (33a) with high inhibitory potency (IC50 = 3.1 nM), satisfactory selectivity, favorable skin permeability, and a well-characterized binding mechanism. Encouragingly, topical administration of 33a exhibited remarkable therapeutic effects in an imiquimod-induced psoriasis mouse model.

Abstract
Hepatic fibrosis commonly exists in chronic liver disease and would eventually develop to cirrhosis and liver cancer with high fatality. Phosphodiesterase-9 (PDE9) has attracted profound attention as a drug target because of its highest binding affinity among phosphodiesterases (PDEs) with cyclic guanosine monophosphate. However, no published study has reported PDE9 inhibitors as potential agents against hepatic fibrosis yet. Herein, structural modification from a starting hit LL01 led to lead 4a, which exhibited an IC50 value of 7.3 nM against PDE9, excellent selectivity against other PDE subfamilies, and remarkable microsomal stability. The cocrystal structure of PDE9 with 4a revealed an important residue, Phe441, capable of improving the selectivity of PDE9 inhibitors. Administration of 4a exerted a significant antifibrotic effect in bile duct-ligation-induced rats with hepatic fibrosis and transforming growth factor-β-induced fibrogenesis. This therapeutic effect was indeed achieved by selectively inhibiting PDE9 rather than other PDE isoforms, identifying PDE9 inhibitors as potential agents against hepatic fibrosis.

Abstract
A novel series of multitargeted molecules were designed and synthesized by combining the pharmacological role of cholinesterase inhibitor and antioxidant of steroid as potential ligands for the treatment of Vascular Dementia (VD). The oxygen-glucose deprivation (OGD) model was used to evaluate these molecules, among which the most potent compound ML5 showed the highest activity. Firstly, ML5 showed appropriate inhibition of cholinesterases (ChEs) at orally 15 mg/kg in vivo. The further test revealed that ML5 promoted the nuclear translocation of Nrf2. Furthermore, ML5 has significant neuroprotective effect in vivo model of bilateral common carotid artery occlusion (BCCAO), significantly increasing the expression of Nrf2 protein in the cerebral cortex. In the molecular docking research, we predicted the ML5 combined with hAChE and Keap1. Finally, compound ML5 displayed normal oral absorption and it was nontoxic at 500 mg/kg, po, dose. We can draw the conclusion that ML5 could be considered as a new potential compound for VD treatment.

Abstract
Due to their unique pharmacological characteristics, methylxanthines are known as therapeutic agents in a fascinating range of medicinal scopes. In this report, we aimed to examine some biological effects of previously synthesized 8-alkylmercaptocaffeine derivatives. Cytotoxic and antioxidative activity of 8-alkylmercaptocaffeine derivatives were measured in malignant A549, MCF7, and C152 cell lines. Assessment of cGMP levels and caspase-3 activity were carried out using a colorimetric competitive ELISA kit. Computational approaches were employed to discover the inhibitory mechanism of synthesized compounds. Among the twelve synthesized derivatives, three compounds (C1, C5, and C7) bearing propyl, heptyl, and 3-methyl-butyl moieties showed higher and more desirable cytotoxic activity against all the studied cell lines (IC50 < 100 µM). Furthermore, C5 synergistically enhanced cisplatin-induced cytotoxicity in MCF-7 cells (CI < 1). Both C5 and C7 significantly increased caspase-3 activity and intracellular cGMP levels at specific time intervals in all studied cell lines (P < 0.05). However, these derivatives did not elevate LDH leakage (P > 0.05) and exhibited no marked ameliorating effects on oxidative damage (P > 0.05). Computational studies showed that H-bond formation between the nitrogen atom in pyrazolo[4,3-D] pyrimidine moiety with Gln817 and creating a hydrophobic cavity result in the stability of the alkyl group in the PDE5A active site. We found that synthesized 8-alkylmercaptocaffeine derivatives induced cell death in different cancer cells through the cGMP pathway. These findings will help us to get a deeper insight into the role of methylxanthines as useful alternatives to conventional cancer therapeutics.

Abstract
Cyclic nucleotide phosphodiesterases (PDEs) are a superfamily of enzymes known to play a critical role in the indirect regulation of several intracellular metabolism pathways through the selective hydrolysis of the phosphodiester bonds of specific second messenger substrates such as cAMP (3',5'-cyclic adenosine monophosphate) and cGMP (3',5'-cyclic guanosine monophosphate), influencing the hypertrophy, contractility, apoptosis and fibroses in the cardiovascular system. The expression and/or activity of multiple PDEs is altered during heart failure (HF), which leads to changes in levels of cyclic nucleotides and function of cardiac muscle. Within the cardiovascular system, PDEs 1-5, 8 and 9 are expressed and are interesting targets for the HF treatment. In this comprehensive review we will present a briefly description of the biochemical importance of each cardiovascular related PDE to the HF, and cover almost all the "long and winding road" of designing and discovering ligands, hits, lead compounds, clinical candidates and drugs as PDE inhibitors in the last decade.

Abstract
To validate the hypothesis that Tyr748 is a crucial residue to aid the discovery of highly selective phosphodiesterase 8A (PDE8A) inhibitors, we identified a series of 2-chloroadenine derivatives based on the hit clofarabine. Structure-based design targeting Tyr748 in PDE8 resulted in the lead compound 3a (IC50 = 0.010 μM) with high selectivity with a reasonable druglike profile. In the X-ray crystal structure, 3a bound to PDE8A with a different mode from 3-isobutyl-1-methylxanthine (a pan-PDE inhibitor) and gave a H-bond of 2.7 Å with Tyr748, which possibly interprets the 220-fold selectivity of 3a against PDE2A. Additionally, oral administration of compound 3a achieved remarkable therapeutic effects against vascular dementia (VaD), indicating that PDE8 inhibitors could serve as potential anti-VaD agents.

Abstract
A series of 10,11-dihydro-5H-dibenzo [b,f]azepine hydroxamates (4-15) were synthesized, behaving as histone deacetylase inhibitors, and examined for their influence on vascular cognitive impairment (VCI), which correlated with dementia. The results revealed that (E)-3-(4-(((3-(3-chloro-10,11-dihydro-5H-dibenzo [b,f]azepin-5-yl)propyl)amino)methyl)phenyl)-N-hydroxy-acrylamide (13) increases cerebral blood flow (CBF), attenuates cognitive impairment, and improves hippocampal atrophy in in vivo study. It is also able to increase the level of histone acetylation (H3K14 or H4K5) in the cortex and hippocampus of chronic cerebral hypoperfusion (CCH) mice; as a result, it could be a potential HDAC inhibitor for the treatment of vascular cognitive impairment.
