Profiling of a prescription drug library for potential renal drug-drug interactions mediated by the organic cation transporter 2

Drug-drug interactions (DDIs) are major causes of serious adverse drug reactions. Most DDIs have a pharmacokinetic basis in which one drug reduces the elimination of a second drug, leading to potentially toxic drug levels. As a major organ of drug elimination, the kidney represents an important site for DDIs. Here, we screened a prescription drug library against the renal organic cation transporter OCT2/SLC22A2, which mediates the first step in the renal secretion of many cationic drugs. Of the 910 compounds screened, 244 inhibited OCT2. Computational analyses revealed key properties of inhibitors versus noninhibitors, which included overall molecular charge. Four of six potential clinical inhibitors were transporter-selective in follow-up screens against additional transporters: OCT1/SLC22A1, MATE1/SLC47A1, and MATE2-K/SLC47A2. Two compounds showed different kinetics of interaction with the common polymorphism OCT2-A270S, suggesting a role of genetics in modulating renal DDIs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 492-08-0, you can also check out more blogs about492-08-0

Nematicidal Activity of Matrine and Its Derivatives against Pine Wood Nematodes

The nematicidal activity of matrine and its derivatives isolated from the epigeal part of Sophora flavescens was examined against the pine wood nematode (Bursaphelenchus xylophilus). The nematicidal activity of matrine, which is one of the major alkaloids in the root of the plant, was poor. However, sophocarpine, one of the unsaturated derivatives of matrine, had strong nematicidal activity against another unsaturated derivative, sophoramine, had such activity, but it was less than that nematodes; another unsaturated derivative, sophoramine, had such activity, but it was less than that of sophocarpine. These results suggest that the degree of unsaturation in the 6-lactam ring of matrine type alkaloids is important to nematicidal activity.

Studies on the complex formation between lactams and thiolactams of sparteine with copper(II) cation

The complex formation for lactams and thiolactams of sparteine with Cu(II) cation in ethanol was studied by theoretical, kinetic and MS methods. The studied compounds with Cu(II) cation formed 1:1 and 1:2 complexes. The kinetic parameters of their formation were determined. Both kinetic and thermodynamic parameters depend strongly on the presence of oxo- or thiono-group in sparteine skeleton.

Analogues of sparteine. 5. Antiarrhythmic activity of selected N,N’-disubstituted bispidines

A series of seven N,N’-disubstituted bispidines, structurally analogous to the inner (B and C) rings of sparteine (1) and encompassing a range of lipophilicity in which 1 was centered, has been compared to 1 in regard to antiarrhythmic potency and acute toxicity. Several of the bispidines were of comparable potency, and all but one were somewhat less toxic than 1. The ability of the mononitrate salts of 1 and bispidines 6 and 7 to bind calcium and magnesium cations in Me2So-d6 solvent has been evaluated by proton magnetic resonance analysis. No binding could be demonstrated under these conditions, which suggested that pharmacologic effects of these compounds may be due to properties other than direct binding of these cations.

Conjugate additions of organolithiums to electron-poor olefins: A simple and useful approach to the synthesis of complex molecules

Conjugate addition reactions of organometallic compounds to electron-poor olefins is a versatile synthetic methodology for the formation of new carbon-carbon bonds. However, a careful control of the regioselectivity of the process is needed because of the presence of two electrophilic sites in the activated olefin. This issue is often overcome by employing “soft” nucleophiles such as organocopper and organozinc reagents, because of their high selectivity towards the 1,4-addition. In contrast, organolithium compounds, which are “hard” nucleophiles, generally give access to 1,2-adducts, 1,4-conjugate addition being sometimes observed according to the nature of nucleophiles and/or electrophiles, or to the presence of additives. In this Minireview, we have described some peculiar examples to get an outline of the recent acquisitions in the field of the conjugate additions of functionalized organolithiums to electron-poor olefins. Particular attention is paid to the synthesis of complex structures starting from simple substrates by means of cascade reactions promoted by conjugate addition reactions with organolithiums.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 492-08-0 is helpful to your research. Related Products of 492-08-0

Exploiting the role of nanoparticle shape in enhancing hydrogel adhesive and mechanical properties

The ability to control nanostructure shape and dimensions presents opportunities to design materials in which their macroscopic properties are dependent upon the nature of the nanoparticle. Although particle morphology has been recognized as a crucial parameter, the exploitation of the potential shape-dependent properties has, to date, been limited. Herein, we demonstrate that nanoparticle shape is a critical consideration in the determination of nanocomposite hydrogel properties. Using translationally relevant calcium-alginate hydrogels, we show that the use of poly(L-lactide)-based nanoparticles with platelet morphology as an adhesive results in a significant enhancement of adhesion over nanoparticle glues comprised of spherical or cylindrical micelles. Furthermore, gel nanocomposites containing platelets showed an enhanced resistance to breaking under strain compared to their spherical and cylindrical counterparts. This study opens the doors to a change in direction in the field of gel nanocomposites, where nanoparticle shape plays an important role in tuning mechanical properties.

C2-Modified Sparteine Derivatives Are a New Class of Potentially Long-Acting Sodium Channel Blockers

The lupin alkaloid sparteine is a well-known chiral diamine with a range of applications in asymmetric synthesis, as well as a blocker of voltage-gated sodium channels (VGSCs). However, there is only scarce information on the VGSC-blocking activity of sparteine derivatives where the structure of the parent alkaloid is retained. Building on the recent renewed availability of sparteine and derivatives we report herein how modification of sparteine at position 2 produces irreversible blockers of VGSCs. These compounds could be clinically envisaged as long-lasting local anesthetics.
