Drug release from porous matrixes based on natural polymers

Background: This review provides a report on recent advances in the field of drug release from matrixes made of natural polymers. Herein, the properties of natural polymers such as proteins and polysaccharides are discussed in general. Selected detailed examples of drug release profiles from biopolymer matrixes have also been collected from scientific literature and practical work, and commented on. In this review, the most common natural polymers, i.e. collagen, elastin, chitosan, hyaluronic acid and sodium alginate have been discussed as biopolymers that can be potentially applied in drug delivery systems. Methodology: The most rapidly developing field of the biomaterials science is the one dealing with their application as matrixes in drug release systems. Such systems show numerous advantages when compared to conventional ones. They improve medical treatment efficiency due to the fact that drugs are placed directly into the infected part. Moreover, the drug release systems reduce toxic reactions because the drug does not pass through the body and, as a result, does not affect the healthy tissues. Such systems also improve the patient?s comfort during the treatment. Result: Biocompatibility, bioresorbability and non-toxicity are the significant properties characteristic for natural polymers. Natural polymers can be used to obtain biomaterials which can further find their applications in the production of bones or soft tissues implants as well as dressing materials placed on damaged skin. Nevertheless, the disadvantages of biomaterials made of natural polymers, e.g., high solubility and low thermal stability, limit the range of their potential applications. Therefore, it is necessary to modify material properties by carrying out the cross-linking process. Conclusion: Recently, a rapidly growing interest in the use of porous materials as controlled drug delivery matrixes has been observed since they present several positive features. The drug release from polymeric matrixes is based on the carrier degradation process which depends on dissolving and diffusion processes. The selection of a polymeric matrix depends on its compatibility with the drug as well as the manufacturing process which needs to be considered. The proper adjustment of the drug release rate is necessary to obtain the best results during medical treatment. Numerous classes of hydrophilic as well as hydrophobic drugs can be released from polymeric matrixes which is beneficial to medical treatment. The research of different drug release systems has already been carried out, and the results can be found in scientific literature.

New Strategies for the Transition-Metal Catalyzed Synthesis of Aliphatic Amines

Transition-metal catalyzed reactions that are able to construct complex aliphatic amines from simple, readily available feedstocks have become a cornerstone of modern synthetic organic chemistry. In light of the ever-increasing importance of aliphatic amines across the range of chemical sciences, this review aims to provide a concise overview of modern transition-metal catalyzed approaches to alkylamine synthesis and their functionalization. Selected examples of amine bond forming reactions include: (a) hydroamination and hydroaminoalkylation, (b) transition-metal catalyzed C(sp3)-H functionalization, and (c) transition-metal catalyzed visible-light-mediated light photoredox catalysis.

Structure-based discovery of prescription drugs that interact with the norepinephrine transporter, NET

The norepinephrine transporter (NET) transports norepinephrine from the synapse into presynaptic neurons, where norepinephrine regulates signaling pathways associated with cardiovascular effects and behavioral traits via binding to various receptors (e.g., beta2-adrenergic receptor). NET is a known target for a variety of prescription drugs, including antidepressants and psychostimulants, and may mediate off-target effects of other prescription drugs. Here, we identify prescription drugs that bind NET, using virtual ligand screening followed by experimental validation of predicted ligands. We began by constructing a comparative structural model of NET based on its alignment to the atomic structure of a prokaryotic NET homolog, the leucine transporter LeuT. The modeled binding site was validated by confirming that known NET ligands can be docked favorably compared to nonbinding molecules. We then computationally screened 6,436 drugs from the Kyoto Encyclopedia of Genes and Genomes (KEGG DRUG) against the NET model. Ten of the 18 high-scoring drugs tested experimentally were found to be NET inhibitors; five of these were chemically novel ligands of NET. These results may rationalize the efficacy of several sympathetic (tuaminoheptane) and antidepressant(tranylcypromine) drugs, as well as side effects of diabetes (phenformin) and Alzheimer’s (talsaclidine) drugs. The observations highlight the utility of virtual screening against a comparative model, even when the target shares less than 30% sequence identity with its template structure and no known ligands in the primary binding site.

Insect muscarinic acetylcholine receptor: Pharmacological and toxicological profiles of antagonists and agonists

The insect muscarinic acetylcholine receptor (mAChR) is evaluated as a potential target for insecticide action. The mammalian M2/M4-selective antagonist radioligand [3H]AF-DX 384 (a pirenzepine analogue) binds to Drosophila mAChR at a single high-affinity site identical to that for the nonselective antagonist [3H]quinuclidinyl benzilate (QNB) and with a pharmacological profile distinct from that of all mammalian mAChR subtypes. Three nonselective antagonists (QNB, scopolamine, and atropine) show the highest affinity (Ki = 0.5-2.4 nM) at the Drosophila target, and AF-DX 384 and M3-selective 4-DAMP (dimethyl-4-(diphenylacetoxy)piperidinium iodide) rank next in potency (Ki = 5-18 nM). Eleven muscarinic antagonists generally exhibit higher affinity than eight agonists. On injection into houseflies, the antagonists 4-DAMP and (S)-(+)-dimethindene produce suppressed movement, the agonist (methyloxadiazolyl)quinuclidine causes knockdown and tremors, and all of them inhibit [3H]-QNB binding ex vivo, indicating possible mAChR-mediated intoxication. The insect mAChR warrants continuing study in lead generation to discover novel insecticides.

Muscarinic effects on cellular functions in cultured human ciliary muscle cells

Purpose. To characterize the pharmacology of the carbachol-induced changes of phospholipase C (PLC) activity and intracellular calcium concentration ([Ca2+](i)) in cultured human ciliary muscle cells. Methods. Changes in PLC activity of cultured human ciliary muscle cells were determined by production of inositol phosphates. Single-cell dynamic fluorescence ratio imaging was used to determine [Ca2+](i). Results. Carbachol, oxotremorine-M, aceclidine, and pilocarpine stimulated PLC with mean EC50s of 20, 8, 17, and 2 muM, respectively. The effect of carbachol on PLC was partially suppressed by extracellular Ca2+ depletion. This muscarinic effect was blocked by muscarinic antagonists, such as atropine (apparent pK(i) = 9.12, nonselective for muscarinic receptor subtypes), pirenzepine (pK(i) = 6.76, selective for the M1 receptor subtype), 4DAMP (pK(i) = 9.25, selective for the M1 and M3 subtypes), and fHHSiD (pK(i) = 7.77, selective for the M3 subtype). In [Ca2+](i) experiments, carbachol increased [Ca2+](i) transients in human ciliary muscle cells in a dose-dependent manner with a mean EC50 of 7 muM. 4DAMP was approximately 100 times more potent than pirenzepine in the inhibition of the carbachol-induced [Ca2+](i) increase. [Ca2+](i) oscillations were observed after carbachol stimulation and persisted after extracellular Ca2+ depletion. Conclusions. Muscarinic agonists activate PLC and increase [Ca2+](i) in cultured human ciliary muscle cells through an M3-like muscarinic receptor subtype.

Muscarinic contraction in isolated guinea-pig trachea and antagonism by noradrenaline

In contrast to other muscarinic agonists, WAL 2014 FU does not induce bronchospasm in laboratory animals. The present investigation was intended to test the hypothesis that this is due to a particular susceptibility of the drug’s effect to antagonism by catecholamines, as a result of partial M3- agonism. The tonic activity of the muscarinic agonists, aceclidine, arecoline, carbachol, McN-A-343, RS 86, thiopilocarpine and WAL 2014 FU, was tested in groups of isolated tracheal muscle of the guinea-pig. Susceptibility to functional antagonism by beta-adrenoceptor stimulation was measured by the displacement of the concentration-force curves by 3 muM noradrenaline. Evaluation of the concentration-force relationship revealed differences in potency and intrinsic activity (carbachol=100%) ranging from 114% for arecoline to 36% for thiopilocarpine (WAL 2014 FU=63%). The catecholamine increased the concentration of agonist which induced 5% of the maximum effect achievable (EC05) values fivefold (carbachol) to more than 4,680 fold (thiopilocarpine) (WAL 2014 FU: 2,860 fold). Regression analysis between the intrinsic activity of the seven compounds and the antagonistic effect of noradrenaline revealed a significant correlation (Spearman correlation coefficient (r(s)) =-0.79; p=0,036). Inhibition of the effects of endogenous catecholamines by beta-adrenolysis with 50 muM toliprolol increased the maximal contraction induced by 1 mM WAL 2014 FU, but did not affect maximal contraction induced by 30 muM arecoline. Pretreatment with 0.3-1.0 mM dibutyrylcyclic adenosine monophosphate (DBcAMP) shifted the concentration- response curves of arecoline, WAL 2014 FU and thiopilocarpine in a similar manner to noradrenaline. The results exclude an important contribution of adenylate cyclase-coupled M2-receptors to the susceptibility of tracheal contraction by muscarinic agonists to functional antagonism by noradrenaline, but emphasize the importance of intrinsic activity at the M3-receptors. The pronounced susceptibility of WAL 2014 FU-induced contraction to functional antagonism by beta-adrenoceptor activation provides an explanation for the failure of the drug to induce bronchospasm in vivo.

3d Transition Metals for C-H Activation

C-H activation has surfaced as an increasingly powerful tool for molecular sciences, with notable applications to material sciences, crop protection, drug discovery, and pharmaceutical industries, among others. Despite major advances, the vast majority of these C-H functionalizations required precious 4d or 5d transition metal catalysts. Given the cost-effective and sustainable nature of earth-abundant first row transition metals, the development of less toxic, inexpensive 3d metal catalysts for C-H activation has gained considerable recent momentum as a significantly more environmentally-benign and economically-attractive alternative. Herein, we provide a comprehensive overview on first row transition metal catalysts for C-H activation until summer 2018.

Thermochemical stability: A comparison between experimental and predicted data

The first step to be performed during the development of a new industrial process should be the assessment of all hazards associated to the involved compounds. Particularly, the knowledge of all substances thermochemical parameters is a primary feature for such a hazard evaluation. CHETAH (CHEmical Thermodynamic And Hazard evaluation) is a prediction software suitable for calculating potential hazards of chemicals, mixtures or a single reaction that, using only the structure of the involved molecules and Benson’s group contribution method, is able to calculate heats of formation, entropies, Gibbs free energies and reaction enthalpies. Because of its ability to predict the potential hazards of a material or mixture, CHETAH is part of the so-called “desktop methods” for early stage chemical safety analysis. In this work, CHETAH software has been used to compile a complete risk database reporting heats of decomposition and Energy Release Potential (ERP) for 342 common use chemicals. These compounds have been gathered into classes depending on their functional groups and similarities in their thermal behavior. Calculated decomposition enthalpies for each of the compounds have also been compared with experimental data obtained with either thermoanalytic or calorimetric techniques (Differential Scanning Calorimeter – DSC – and Accelerating Rate Calorimeter – ARC).
