Structurally simple synthetic 1,4-disubstituted piperidines with high selectivity for resistant Plasmodium falciparum

Background: Emergence of resistance to artemisinins and some of their combinations in chemotherapy of clinical malaria has intensified the search for novel safe efficacious antimalarial molecules. Fourteen synthetic 1,4-disubstituted piperidines with simple molecular structures were evaluated in this study. Methods: Antiplasmodial activity were determined against cultured chloroquine-sensitive 3D7 and resistant Dd2 strains of P. falciparum by in vitro parasite growth inhibition. A primary screen was done to identify active compounds by fluorescence microscopy followed by a secondary screen to determine IC50 and IC90 values of active compounds by the parasite lactate dehydrogenase assay. Cytotoxicity of active compounds was assessed using the MTT/formazan assay and selectivity indices (SIs) determined. Optical densities were analysed to obtain experimental results. Results: The compounds produced 56 to 93% inhibition of parasite growth at 40 mu g/mL. Eight compounds (2 ketone, 5 alcohol and one amine analogues) showed high activity (IC(50)s between 1 and 5 mu g/mL). Nine compounds were highly selective for the parasite (SIs = 15 to 182). Three promising (alcohol) analogues were identified: [1-(4-fluorobenzyl) piperidin- 4-yl] [4-fluorophenyl] methanol, (7), [1-(3, 4-dichlorobenzyl) piperidin-4-yl] [4- fluorophenyl] methanol (8) and [1-(4-bromobenzyl) piperidin-4-yl] [4- fluorophenyl] methanol (11) which were more active on the resistant strain (IC50 values between 1.03 to 2.52 mu g/mL), than the sensitive strain (IC50 values between 2.51 to 4. 43 mu g/mL). Conclusions: The alcohol analogues were the most active and most selective for the parasite with three promising hit molecules identified among them, suggesting the hydroxyl group at C-7′ in these alcohol analogues is contributing greatly to their antiplasmodial activity. Further exploration of the core structure using chemistry approaches and biological screening including in vivo studies in an animal model of malaria may yield important antimalarial leads.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4727-72-4, in my other articles.

Labelled micelles for the delivery of cytotoxic Cu(II) and Ru(III) compounds in the treatment of aggressive orphan cancers: Design and biological in vitro data

A recent study on our metal-dithiocarbamato complexes pointed out the antiproliferative properties and the druglikeness of some new patented derivatives. In this work, the best compounds have been encapsulated in micellar nanocarriers, being also carbohydrate-functionalized on their hydrophilic surface to investigate the possibility of a cancer-selective delivery. In particular, the nonionic block copolymer Pluronic (R) F127 (PF127) has been chemically modified with sugars and the derivatives characterized by means of NMR spectroscopy and FT-IR spectrophotometry. Then, the two selected complexes (beta-[Ru-2(PipeDTC)(5)]Cl (PipeDTC = piperidine dithiocarbamate) and [Cu(ProOMeDTC)(2)] (ProOMeDTC = L-proline methyl ester dithiocarbamate)), have been loaded into the hydrophobic core of PF127 micelles and cancer-targeting counterparts. These nanoformulations have been studied for their dimensions (DLS, TEM) and stability, and tested for their cytotoxicity against aggressive human cancer cell lines. The in vitro results were paralleled with mechanistic studies through Confocal Laser Scanning Microscopy and xCELLigence analysis.

Structural Basis of Beneficial Design for Effective Nicotinamide Phosphoribosyltransferase Inhibitors

Inhibition of nicotinamide phosphoribosyltransferase (NAMPT) is an attractive therapeutic strategy for targeting cancer metabolism. So far, many potent NAMPT inhibitors have been developed and shown to bind to two unique tunnel-shaped cavities existing adjacent to each active site of a NAMPT homodimer. However, cytotoxicities and resistances to NAMPT inhibitors have become apparent. Therefore, there remains an urgent need to develop effective and safe NAMPT inhibitors. Thus, we designed and synthesized two close structural analogues of NAMPT inhibitors, azaindole-piperidine (3a)- and azaindole-piperazine (3b)-motif compounds, which were modified from the well-known NAMPT inhibitor FK866 (1). Notably,3adisplayed considerably stronger enzyme inhibitory activity and cellular potency than did3band1. The main reason for this phenomenon was revealed to be due to apparent electronic repulsion between the replaced nitrogen atom (N1) of piperazine in3band the N delta atom of His191 in NAMPT by our in silico binding mode analyses. Indeed,3bhad a lower binding affinity score than did3aand1, although these inhibitors took similar stable chair conformations in the tunnel region. Taken together, these observations indicate that the electrostatic enthalpy potential rather than entropy effects inside the tunnel cavity has a significant impact on the different binding affinity of3afrom that of3bin the disparate enzymatic and cellular potencies. Thus, it is better to avoid or minimize interactions with His191 in designing further effective NAMPT inhibitors.

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 179474-79-4 is helpful to your research. Safety of 1-(3-Methoxypropyl)piperidin-4-amine.

Muscarinic Acetylcholine Receptors Modulate Interleukin-6 Production and Immunoglobulin Class Switching in Daudi Cells

B cells express muscarinic and nicotinic acetylcholine receptors (mAChRs and nAChRs, respectively). Following immunization with ovalbumin, serum immunoglobulin G (IgG) and interleukin (IL)-6 levels were lower in M-1 and M-5 mAChR double-deficient mice and higher in alpha 7 nAChR-deficient mice than in wild-type mice. This suggests mAChRs participate in the cytokine production involved in B cell differentiation into plasma cells, which induces immunoglobulin class switching from IgM to IgG. However, because these results were obtained with conventional knockout mice, in which all cells in the body were affected, the specific roles of these receptors expressed in B cells remains unclear. In the present study, Daudi B lymphoblast cells were used to investigate the specific roles of mAChRs and nAChR in B cells. Stimulating Daudi cells using Pansorbin cells (heat-killed, formalin-fixed Staphylococcus aureus coated with protein A) upregulated expression of M-1-M-4 mAChRs and the alpha 4 nAChR subunit. Under these conditions, mAChRs, but not nAChRs, mediated immunoglobulin class switching to IgG. This effect was blocked by scopolamine, a non-selective mAChR antagonist, and 4-diphenylacetoxy-N-methyl-piperidine methiodide (4-DAMP), a G(q/11)-coupled M-1, M-3, M-5 antagonist. In addition, IL-6 secretion was further enhanced following mAChR activation. Thus, G(q/11)-coupled mAChRs expressed in B cells thus appear to contribute to IL-6 production and B cell maturation into IgG-producing plasma cells.

Synthesis and Evaluation of a New Acryloyl-Based Copolymer as Kinetic Hydrate Inhibitor for Sour Gas Environments

Blockage of gas flow lines by gas hydrates is a major problem in the oil and gas industry, which leads to severe safety issues and causes economic losses. Kinetic hydrate inhibitors (KHIs) are water-soluble polymers that are employed to circumvent this problem due to their effectiveness at low dosage, which makes logistics (transport, storage, and pumping) less costly particularly in offshore operations. However, some of the currently available KHI polymers have subcooling constraints against class I hydrates in high sour gas conditions, which limit their utilization. In this Article, we report a new KHI copolymer synthesized from N-acryloyl pyrrolidine and N-acryloyl piperidine monomers. Detailed characterization and compatibility studies were carried out using a variety of techniques and tests. The rocking cell test demonstrated the new formulation’s effectiveness to a high subcooling temperature of 8.5 degrees C at 140 bar of a gas mixture containing a high concentration of CO2 and H2S. The performance of the copolymer was investigated at 2% and 3% dosage, where the increased dosage of copolymer showed a higher subcooling temperature. Collectively, these results set a stage for the design, development, and evaluation of a new type of polymers as an effective KHI.

Characterization of reactive intermediates formation in dacomitinib metabolism and bioactivation pathways elucidation by LC-MS/MS: in vitro phase I metabolic investigation

Dacomitinib (DCB) is a second generation irreversible tyrosine kinase inhibitor (TKI) that is claimed to overcome the disadvantages of the resistance developed by the first line epidermal growth factor receptor (EGFR) TKIs. In the current study, metabolites of phase I for DCB were systematically explored. DCB reactive metabolites were also investigated in rat liver microsomes in presence of potassium cyanide or methoxylamine that were employed as capturing agents for iminium reactive intermediates and aldehyde, respectively, to form stable complexes which can be detected by LC-MS/MS. As a result, four in vitro phase I metabolites were observed with major pathway of piperidine ring hydroxylation. Additionally, two potentially reactive intermediates, one aldehyde and one iminium ions were characterized. Two different pathways of bioactivation were ultimately proposed.

Chlorination of 2-substituted 1-hydroxyindoles

Chlorination of 1-hydroxyindole-5,6-dicarbonitriles and 1-hydroxypyrrolo[3,4-f]indole-5,7(1H,6H)-diones with N-chlorosuccinimide afforded previously unknown 3,3-dichloro-3Hindole 1-oxides instead of the expected 3-chloro-1-hydroxyindoles. The latter, however, were prepared in good yields by treatment of the above 3,3-dichloro-3H-indole 1-oxides with piperidine in ethanol. Reduction of 3,3-dichloro-5,6-dicyano-3H-indole 1-oxides with Zn in AcOH yielded the corresponding 3-chloroindole-5,6-dicarbonitriles.

Multistage antiplasmodial activity of hydroxyethylamine compounds,in vitroandin vivoevaluations

Malaria, a global threat to the human population, remains a challenge partly due to the fast-growing drug-resistant strains ofPlasmodiumspecies. New therapeutics acting against the pathogenic asexual and sexual stages, including liver-stage malarial infection, have now attained more attention in achieving malaria eradication efforts. In this paper, two previously identified potent antiplasmodial hydroxyethylamine (HEA) compounds were investigated for their activity against the malaria parasite’s multiple life stages. The compounds exhibited notable activity against the artemisinin-resistant strain ofP. falciparumblood-stage culture with 50% inhibitory concentrations (IC50) in the low micromolar range. The compounds’ cytotoxicity on HEK293, HepG2 and Huh-7 cells exhibited selective killing activity with IC(50)values > 170 mu M. Thein vivoefficacy was studied in mice infected withP. bergheiNK65, which showed a significant reduction in the blood parasite load. Notably, the compounds were active against liver-stage infection, mainly compound1with an IC(50)value of 1.89 mu M. Mice infected withP. bergheisporozoites treated with compound1at 50 mg kg(-1)dose had markedly reduced liver stage infection. Moreover, both compounds prevented ookinete maturation and affected the developmental progression of gametocytes. Further, systematicin silicostudies suggested both the compounds have a high affinity towards plasmepsin II with favorable pharmacological properties. Overall, the findings demonstrated that HEA and piperidine possessing compounds have immense potential in treating malarial infection by acting as multistage inhibitors.
