In silico and in vitro studies on interaction of novel non-imidazole histamine H3R antagonists with CYP3A4

The paper presents in silico study to explain differences in the influence of the series of non-imidazole histamine receptor H-3 ligands on the activity of cytochrome P-450 3A4 isoform, which was verified in in vitro tests. The compounds appeared to induce broad range of effects – from significant inhibition (-61% reduction of CYP3A4 control activity) to extreme activation (+713% of control activity). Structure-activity relationship for examined compounds was analyzed, with special attention paid to the influence of substituent and the chain length. Docking, molecular dynamics studies, and their statistical analysis allowed to identify those interactions that can be responsible for determination of particular activity type of a compound toward CYP3A4 (activation/inhibition). It resulted in indication of several amino acid residues, which should be carefully analyzed during estimation of compound effects on CYP3A4 activity.

Piperine Encapsulation within Cucurbit[n]uril (n=6,7): A Combined Experimental and Density Functional Study

The formation of host-guest between piperine and cucurbit[n]uril (n = 6,7) molecules were studied using experimental and density functional theory (DFT) calculations. The host-guest complexation was monitored using UV-Visible and isothermal calorimetric (ITC) methods. The obtained Jobs plot indicate the formation of 1:1 complex. ITC analysis shows a moderate binding of the guest to the host molecules. The enthalpy of binding and the free energy of formation were negative indicating the facile formation of inclusion complex at room temperature. DFT studies confirm the formation of stable inclusion complexes. In stable inclusion complex of piperine with cucurbit[6]uril, the aromatic moiety was found to be inside the cucurbituril cavity, while in the cucurbit[7]uril inclusion complex, the piperidine moiety was inside the cavity, which was further confirmed by time dependent-DFT study. The global reactivity descriptors analysis, indicate the formation of piperine inclusion complex with cucurbit[7]uril, could prevent the isomerization reaction of piperine. Atoms-in-molecules analysis shows the presence of extra inter and intramolecular bond critical points in the piperine inclusion complex with cucurbit[7]uril, which accounts for its extra stability. The computed intermolecular bond parameters confirm the existence of a non-covalent with partial electrostatic interactions between the guest and host molecules. Energy decomposition analysis, suggest the Pauli repulsion to be higher for the cucurbit[6]uril inclusion complex, while the dispersion plays a major role in stabilizing the cucurbit[7]uril inclusion complex, which was further corroborated by noncovalent index analysis.

Application of 827026-45-9, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 827026-45-9 is helpful to your research.

Impregnation of Polycarbonate by Paramagnetic Probe 2,2,6,6-Tetramethyl-4-Hydroxy-Piperidine-1-Oxyl (TEMPOL) in Supercritical CO2

The aim of the research was to test the advantages of spin probe electron paramagnetic resonance approach in studying polymers impregnation with organic molecules in supercritical CO2 (scCO(2)) The impregnation of bisphenol A polycarbonate with the spin probe TEMPOL was carried out at 307-343 K and 11.6-35 MPa. The mean and local concentrations of the spin probe in the polymer were evaluated. An increase in temperature and pressure resulted in a more even distribution of the dopant in the polymer matrix. It was observed that, at 307 K and 19.6 MPa, the spin probe was located only near the surface of the sample. Local mobility of the spin probe molecules was found to be similar in polycarbonate films impregnated in scCO(2) and cast from dichloroethane solution. It was shown that changes in the structure of the surface and bulk of the polymer detected by the atomic force and optical polarization microscopy are not directly related with the distribution of the dopant molecules and their average content in the polymer.

Self-organization of silicates on different length scales exemplified by amorphous mesoporous silica and mesoporous zeolite beta using multiammonium surfactants

In this study the structure directing effect of a gemini-type piperidine-based multi-ammonium surfactant during hydrothermal zeolite synthesis was investigated for two cases: with and without a source of aluminum. The absence of an aluminum source led to the formation of an amorphous mesoporous MCM-48 type silica material, while the presence of aluminum guaranteed the formation of zeolite beta with a hierarchical pore system. The two opposing cases were studied in a time and temperature-dependent manner. The mobility and through space interaction of these large surfactant molecules were studied by liquid state nuclear magnetic resonance (NMR) at a temperature relevant to hydrothermal synthesis (363 K) in pure water and upon addition of an aluminum and silicon source. In the gel state, at different stages of aging and hydrothermal synthesis, low angle X-ray diffraction (XRD) and solid state magic angle spinning nuclear magnetic resonance (H-1 MAS NMR) spectrometry determined the developing order within the system. At each of these different synthesis steps the respective intermediate materials were calcined. Transmission electron microscopy then allowed closer inspection of the locally developing mesoscopic order, while N-2 physisorption was used to follow the evolution of porosity.

Iron and Physical Activity: Bioavailability Enhancers, Properties of Black Pepper (Bioperine(R)) and Potential Applications

Black pepper (Piper nigrumL.) has been employed in medicine (epilepsy, headaches, and diabetes), where its effects are mainly attributed to a nitrogen alkaloid called piperidine (1-(1-[1,3-benzodioxol-5-yl]-1-oxo-2,4 pentenyl) piperidine). Piperine co-administered with vitamins and minerals has improved its absorption. Therefore, this study aimed to describe the impact of the joint administration of iron (Fe) plus black pepper in physically active healthy individuals. Fe is a micronutrient that aids athletic performance by influencing the physiological functions involved in endurance sports by improving the transport, storage, and utilization of oxygen. Consequently, athletes have risk factors for Fe depletion, Fe deficiency, and eventually, anemia, mainly from mechanical hemolysis, gastrointestinal disturbances, and loss of Fe through excessive sweating. Declines in Fe stores have been reported to negatively alter physical capacities such as aerobic capacity, strength, and skeletal muscle recovery in elite athletes. Thus, there is a need to maintain Fe storage, even if Fe intake meets the recommended daily allowance (RDA), and Fe supplementation may be justified in physically active individuals, in states of Fe deficiency, with or without anemia. Females, in particular, should monitor their Fe hematological profile. The recommended oral Fe supplements are ferrous or ferric salts, sulfate, fumarate, and gluconate. These preparations constitute the first line of treatment; however, the high doses administered have gastrointestinal side effects that reduce tolerance and adherence to treatment. Thus, a strategy to counteract these adverse effects is to improve the bioavailability of Fe. Therefore, piperine may benefit the absorption of Fe through its bioavailability enhancement properties. Three research studies of Fe associated with black pepper have reported improvements in parameters related to the metabolism of Fe, without adverse effects. Although more research is needed, this could represent an advance in oral Fe supplementation for physically active individuals.

Discovery of MK-8282 as a Potent G-Protein-Coupled Receptor 119 Agonist for the Treatment of Type 2 Diabetes

The ever-growing prevalence of type 2 diabetes in the world has necessitated an urgent need for multiple orally effective agents that can regulate glucose homeostasis with a concurrent reduction in body weight. G-Protein coupled receptor 119 (GPR119) is a GPCR target at which agonists have demonstrated glucose-dependent insulin secretion and shows beneficial effects on glycemic control. Herein, we describe our efforts leading to the identification of a potent, oral GPR-119 agonist, MK-8282, which shows improved glucose tolerance in multiple animal models and has excellent off-target profile. The key design elements in the compounds involved a combination of a fluoro-pyrimidine and a conformationally constrained bridged piperidine to impart good potency and efficacy.

Comparative Genotoxicity of TEMPO and 3 of Its Derivatives in Mouse Lymphoma Cells

TEMPO (2, 2, 6, 6-tetramethylphiperidine-1-oxyl) and its derivatives are stable free radical nitroxides widely used in the field of chemistry, biology, and pharmacology. TEMPO was previously found to be mutagenic and to induce micronuclei in mammalian cells. In this study, we investigated and quantified the genotoxicity of 4 structurally similar nitroxides, TEMPO and 3 of its derivatives (4-hydroxy-TEMPO, 4-oxo-TEMPO, and 4-methoxy-TEMPO), using the mouse lymphoma assay (MLA) and Comet assay in L5178Y Tk(+/-) cells. The results showed that all tested nitroxides were cytotoxic and mutagenic in the MLA, both in the presence and absence of S9, with metabolic activation significantly enhancing the cytotoxicity and/or mutagenicity. In addition, the 4 nitroxides caused DNA-strand breakage. The mutagenicity and DNA damaging dose-responses of the test articles were compared using the PROAST benchmark dose software package. The potency ranking of the 4 nitroxides for mutagenicity was different from the ranking of the DNA damaging effects. The mode of action analysis by a multi-endpoint DNA damage pathway assay classified all 4 nitroxides as clastogens. In addition, the majority of the induced Tk mutants showed loss of heterozygosity at the Tk and D11Mit42 loci (ie, chromosome damage <31 Mbp). These results suggest that TEMPO and its 3 derivatives are cytotoxic and mutagenic in mouse lymphoma cells through a mechanism that involves strand breakage and large alterations to DNA. The potency rankings indicate that the different TEMPO derivatives vary in their mutagenic and DNA damaging potential. Interested yet?
