Depression involving neuroinflammation is one of the most common disabling and life-threatening psychiatric disorders. Phosphodiesterase 4 (PDE4) inhibitors produce potent antidepressant-like and cognition-enhancing effects. However, their clinical utilit

In this study, catecholamides (7a–l) bearing different aromatic rings (such as pyridine-2-yl, pyridine-3-yl, phenyl, and 2-chlorophenyl groups) were synthesized as potent phosphodiesterase (PDE) 4 inhibitors. The inhibitory activities of these compounds w

In this study, a series of catechol-based amides (8a-n) with different amide linkers linking the catecholic moiety to the terminal phenyl ring was designed and synthesized as potent phosphodiesterase (PDE) 4D inhibitors. The inhibitory activities of these compounds were evaluated against the core catalytic domains of human PDE4 (PDE4CAT), full-length PDE4B1 and PDE4D7 enzymes, and other PDE family members. The results indicated the majority of compounds 8a-n displayed moderate to good inhibitory activities against PDE4CAT. Among these compounds, compound 8j with a short amide linker (-CONHCH2-) displayed comparable PDE4CAT inhibitory activity (IC50 = 410 nM) with rolipram. More interestingly, compound 8g, a potent and selective PDE4D inhibitor (IC50 = 94 nM), exhibited a 10-fold selectivity over the PDE4B subtypes and an over 1000-fold selectivity against other PDE family members. Docking simulations suggested that 8g forms three extra H-bonds with the N-H of residue Asn487 and two water molecules.
Synthesis, biological evaluation, and molecular modeling of new 3-(cyclopentyloxy)-4-methoxybenzaldehyde O-(2-(2,6-dimethylmorpholino)-2- oxoethyl) oxime (GEBR-7b) related phosphodiesterase 4D (PDE4D) inhibitors

A new series of 3-(cyclopentyloxy)-4-methoxyphenyl derivatives, structurally related to our hit GEBR-4a (1) and GEBR-7b (2), has been designed by changing length and functionality of the chain linking the catecholic moiety to the terminal cycloamine portion. Among the numerous molecules synthesized, compounds 8, 10a, and 10b showed increased potency as PDE4D enzyme inhibitors with respect to 2 and a good selectivity against PDE4A4, PDE4B2, and PDE4C2 enzymes, without both cytotoxic and genotoxic effects. The ability to enhance cAMP level in neuronal cells was assessed for compound 8. SAR considerations, also confirmed by in silico docking simulations, evidenced that both chain and amino terminal function characterized by higher hydrophilicity are required for a good and selective inhibitor-catalytic pocket interaction.

Trypanosomal phosphodiesterases B1 and B2 (TbrPDEB1 and TbrPDEB2) play an important role in the life cycle of Trypanosoma brucei, the causative parasite of human African trypanosomiasis (HAT), also known as African sleeping sickness. We used homology modeling and docking studies to guide fragment growing into the parasite-specific P-pocket in the enzyme binding site. The resulting catechol pyrazolinones act as potent TbrPDEB1 inhibitors with IC50 values down to 49 nM. The compounds also block parasite proliferation (e.g., VUF13525 (20b): T. brucei rhodesiense IC50 = 60 nM, T. brucei brucei IC50 = 520 nM, T. cruzi = 7.6 μM), inducing a typical multiple nuclei and kinetoplast phenotype without being generally cytotoxic. The mode of action of 20b was investigated with recombinantly engineered trypanosomes expressing a cAMP-sensitive FRET sensor, confirming a dose-response related increase of intracellular cAMP levels in trypanosomes. Our findings further validate the TbrPDEB family as antitrypanosomal target.
