PDE7-selective and dual inhibitors: Advances in chemical and biological research

Phosphodiesterase 7 (PDE7) is an intracellular enzyme that specifically hydrolyzes the second messenger, cyclic-3?,5?-adenosine monophosphate (cAMP), into inactive noncyclic nucleotide, 5?-AMP. To date, many structurally diverse compounds with PDE7 inhibitory properties have been described, including selective PDE7 inhibitors, dual PDE4/PDE7, PDE7/PDE8, and PDE7/GSK-3 inhibitors, and non-selective PDE inhibitors with high affinity for PDE7. Inhibitors of PDE7 have provided beneficial effects in animal models of inflammatory and neurological disorders, including Alzheimer?s disease, Parkinson?s disease, multiple sclerosis, and many others. This review is a comprehensive summary of the current state-of-the-art in the field of design and synthesis of PDE7 inhibitors, their physicochemical properties, biological evaluation, and structure-activity relationships as well as it highlights the updated evidence for a potential therapeutic utility of these compounds. Moreover, new approaches to obtain more effective and safer PDE7 inhibitors than those available now are presented.

Synthesis, characterization and biological activity of some new heterocyclic compounds derived from 4- aminoacetophenone

Our work aimed for organic synthesis and biological investigation of some new heterocyclic derivatives by three steps: the first step included synthesis of some five-membered and six-membered heterocyclic derivatives (Pyrazole, Isoxazole, Oxazine and Thiazine) from Chalcone. The second step included synthesis of some 1,3-Oxazipene derivatives from Schiff’s bases derived from Azo compound. The third step included the assay of biological activity of all compounds against four types of pathogens bacteria (Staphylococcus aureus, Granutice tella adiacens) gram positive and ( E. coli, Proteus mirabilis) gram negative the results exhibited excellent biological activity for all derivatives compared to antibiotics (Ampicillin and Ciprofloxacin). These compounds were identified and confirmed by FT- IR, 1HNMR, 13CNMR and elemental analysis.

Bispidine as a privileged scaffold

The diazabicyclic molecule bispidine named by the chemist Carl Mannich in 1930, is a naturally occurring scaffold with interesting features. Bispidine can form different conformers, has high basicity, can attack dichloromethane, has metal ion coordination properties and interacts with nicotinic acetylcholine receptors. In this review we will discuss important properties, synthetic pathways and biological activities of bispidine and some derivatives. Bispidine can function as a scaffold for compounds with very diverse biological activities, e.g. interacting with ion channels, G-protein coupled receptors, and enzymes, and is even used for the development of new in vivo radiotracers.

Analysis of hydrogen-bond complexation constants in 1,1,1-trichloroethane: The alpha2Hbeta2H relationship

Hydrogen-bond complexation constants determined by Taylor and co-workers using 1,1,1-trichloroethane (TCE) solvent have been analysed through the alpha2Hbeta2H relationship; alpha2H and beta2H are the solute hydrogen-bond acidity and basicity parameters obtained from complexation constants in tetrachloromethane. Constants for three alcohol/N-methylpyrrolidinone complexations have been determined in TCE, and if these are used instead of the original alcohol/N-methylpyrrolidinone complexation constants, a good relationship is obtained, eqn. (i). The slope in eqn. (i) is smaller than that for the alpha2Hbeta2H relationship in tetrachloromethane, but the intercept is the same. log K = 6.856 alpha2H – 1.144 (i) n = 84, r2 = 0.9604, sd = 0.16, F = 1993 Eqn. (i) has been used to obtain 25 new alpha2H values for acids; these include acetanilides, sulfonamides, triazoles and tetrazoles. The latter two types of compound have very large alpha2H values; that for 5-phenyl-1,2,3,4-tetrazole (0.88) being near the value for dichloroacetic acid (0.90). Values of beta2Hfor 31 hydrogen-bond bases have also been calculated using eqn. (i). These include bases with heterocyclic moieties to which beta2H values had not previously been assigned, e.g. oxazole, isoxazole, triazoles and a tetrazole.

Novel 1,3,4-triaryl pyrazoles: Synthesis, QSAR studies and cytotoxicity against breast cancer

Background: The existence of drug-resistance and lack of selectivity encourages scientists to search for novel and more selective cytotoxic agents. Objectives: In this work, novel 1,3,4-triarylpyrazole derivatives were synthesized to study their cytotoxicity on MCF7 (human breast Cell Line). In addition, QSAR studies were performed to show the relation between the cytotoxic activity and the structural features of our new synthesized pyrazole derivatives. Methods: Pyrazole-4-carbaldehyde derivative 3 was utilized as a starting material for the preparation of the new pyarazole derivatives. These target compounds were screened for their cytotoxic activity against MCF-7 followed by study cell cycle of the most active compounds. Finally, pharmacophore modeling and QSAR Studies was carried out. Results: Among these compounds; 5d and 8b showed the highest anti-proliferative activity (IC50 = 4.9 and 2.11 muM, respectively). Flow cytometric analysis showed that, compounds 5d and 8b arrested the cell cycle in addition to induction of apoptosis in MCF7 cells. Moreover, their stimulation effect on caspases 3/7 was examined to explore their mechanism of induction of apoptosis and the results showed that their proapoptotic activity could be due to the activation of caspases 3/7. Conclusion: Pyrazole derivatives 5d and 8b displayed potent bioactivities, indicating that these compounds could be considered as a new lead for more investigation in the future.

Aquatic phototransformation study of the antifouling agent Sea-Nine 211: Identification of byproducts and the reaction pathway by gas chromatography-mass spectroscopy

The photochemical behaviour of the biocide Sea-Nine 211 was carried out in order to investigate several transformation products formed in different environmental matrices and under different conditions. Sea-Nine 211 photodecomposition was performed under laboratory conditions using a xenon light source and under natural sunlight conditions in sea, river, lake as well as in distilled water. In order to examine the effect of dissolved organic matter (DOM), the phototransformation of the tested biocide was studied also in the presence of various concentrations of humic and fulvic acids. The phototransformation was shown to proceed via pseudo-first-order reaction in all cases and the presence of humic and fulvic acids enhanced the photolysis reaction. Kinetic experiments were monitored with GC-ECD and the half-lives (t1/2) varied between 6 and 433 h. Irradiation of the aqueous Sea-Nine 211 solutions gave rise to a great number of transformation products that were isolated by means of SPE using SDB extraction disks while six of them were tentatively identified using GC-MS techniques. Based on this byproduct identification a possible transformation pathway is proposed for the decomposition of Sea-Nine 211 in aqueous media.

Multivalent dual pharmacology muscarinic antagonist and beta2 agonist (MABA) molecules for the treatment of COPD

Inhaled beta-2-adrenergic receptor (beta2) agonists and inhaled muscarinic acetylcholine antagonists are the most frequently used bronchodilators in the treatment of chronic obstructive pulmonary disease. While short-acting agents (4-6 h) serve as ‘rescue’ therapy, long-acting (12-24 h) bronchodilators can reduce the incidence and number of exacerbations as well as improve lung function. Due to the complementary nature of the two mechanisms, combinations of the two classes provide even greater improvement in lung function than either mechanism alone. This review focuses on the multivalent origins of dual pharmacology MABA bronchodilators and describes the supporting in vitro characterization and reported animal studies. Topics discussed include approaches taken to identify novel MABA molecules, highlighting preferred muscarinic and beta2-binding groups and how these two entities are linked together; challenges in designing MABA molecules; and the potential benefits of enhanced bronchoprotection and opportunity for ‘triple therapy’ with an inhaled corticosteroid.
