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.

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.

Bis(het)aryl-1,2,3-triazole quinuclidines as alpha7 nicotinic acetylcholine receptor ligands: Synthesis, structure affinity relationships, agonism activity, [18F]-radiolabeling and PET study in rats

In this paper we describe the design and synthesis of bis(Het)Aryl-1,2,3-triazole quinuclidine alpha7R ligands using an efficient three-step sequence including a Suzuki-Miyaura cross coupling reaction with commercially available and home-made boron derivatives. The exploration of SAR required the preparation of uncommon boron derivatives. Forty final drugs were tested for their ability to bind the target and nine of them exhibited Ki values below nanomolar concentrations. The best scores were always obtained when the 5-phenyl-2-thiophenyl core was attached to the triazole. The selectivity of these compounds towards the nicotinic alpha4beta2 and serotoninergic 5HT3 receptors was assessed and their brain penetration was quantified by the preparation and in vivo evaluation of two [18F] radiolabelled derivatives. It can be expected from our results that some of these compounds will be suitable for further developments and will have effects on cognitive disorders.
