Poirier, Marion;Pujol-Gimenez, Jonai;Manatschal, Cristina;Buhlmann, Sven;Embaby, Ahmed;Javor, Sacha;Hediger, Matthias A.;Reymond, Jean-Louis research published 《 Pyrazolyl-pyrimidones inhibit the function of human solute carrier protein SLC11A2 (hDMT1) by metal chelation》, the research content is summarized as follows. Solute carrier proteins (SLCs) control fluxes of ions and mols. across biol. membranes and represent an emerging class of drug targets. SLC11A2 (hDMT1) mediates intestinal iron uptake and its inhibition might be used to treat iron overload diseases such as hereditary hemochromatosis. Here we report a micromolar (IC₅₀ = 1.1 μM) pyrazolyl-pyrimidone inhibitor of radiolabeled iron uptake in hDMT1 overexpressing HEK293 cells acting by a non-competitive mechanism, which however does not affect the electrophysiol. properties of the transporter. Isothermal titration calorimetry, competition with calcein, induced precipitation of radioactive iron and cross inhibition of the unrelated iron transporter SLC39A8 (hZIP8) indicate that inhibition is mediated by metal chelation. Mapping the chem. space of thousands of pyrazolo-pyrimidones and similar 2,2′-diazabiaryls in ChEMBL suggests that their reported activities might partly reflect metal chelation. Such metal chelating groups are not listed in pan-assay interference compounds (PAINS) but should be checked when addressing SLCs.

Ratni, H.;Baumann, K.;Bellotti, P.;Cook, X. A.;Green, L. G.;Luebbers, T.;Reutlinger, M.;Stepan, A. F.;Vifian, W. research published 《 Phenyl bioisosteres in medicinal chemistry: discovery of novel γ-secretase modulators as a potential treatment for Alzheimer′s disease》, the research content is summarized as follows. Ph rings are one of the most prevalent structural moieties in active pharmaceutical ingredients, even if they often contribute to poor physico-chem. properties. Herein, we propose the use of a bridged piperidine (BP) moiety as a Ph bioisostere, which could also be seen as a superior Ph alternative as it led to strongly improved drug like properties, in terms of solubility and lipophilicity. Addnl., this BP moiety compares favorably to the recently reported saturated Ph bioisosteres. We applied this concept to our γ-secretase modulator (GSM) project for the potential treatment of Alzheimer′s disease delivering clin. candidates.

Ravi, Srimadhavi;Barui, Sugata;Kirubakaran, Sivapriya;Duhan, Parul;Bhowmik, Kaushik research published 《 Synthesis and Characterization of Quinoline-3-Carboxamide Derivatives as Inhibitors of the ATM Kinase》, the research content is summarized as follows. Background: The importance of inhibiting the kinases of the DDR pathway for radiosensitizing cancer cells is well established. Cancer cells exploit these kinases for their survival, which leads to the development of resistance towards DNA damaging therapeutics. Objective: In this article, the focus is on targeting the key mediator of the DDR pathway, the ATM kinase. A new set of quinoline-3-carboxamides, as potential inhibitors of ATM, is reported. Methods: Quinoline-3-carboxamide derivatives were synthesized and cytotoxicity assay was performed to analyze the effect of mols. on different cancer cell lines like HCT116, MDA-MB-468, and MDA-MB-231. Results: Three of the synthesized compounds showed promising cytotoxicity towards a selected set of cancer cell lines. Western Blot anal. was also performed by pre-treating the cells with quercetin, a known ATM upregulator, by causing DNA double-strand breaks. SAR studies suggested the importance of the electron-donating nature of the R group for the mol. to be toxic. Finally, Western-Blot anal. confirmed the down-regulation of ATM in the cells. Addnl., the PTEN neg. cell line, MDA-MB-468, was more sensitive towards the compounds in comparison with the PTEN pos. cell line, MDA-MB-231. Cytotoxicity studies against 293T cells showed that the compounds were at least three times less toxic when compared with HCT116. Conclusion: In conclusion, these experiments will lay the groundwork for the evolution of potent and selective ATM inhibitors for the radio- and chemo-sensitization of cancer cells.

Rebane, Riin;Herodes, Koit research published 《 Matrix interference in LC-ESI-MS/MS analysis of metanephrines in protein precipitated plasma samples》, the research content is summarized as follows. Metanephrine and normetanephrine are measured in blood plasma to diagnose different diseases. Simpler sample preparation procedures are preferred but tend to yield less purified extracts Therefore, thorough investigation of matrix effects is required. In this work, several sample preparation methods and chromatog. modes were compared for liquid chromatog. tandem mass spectrometric (with electrospray ionization; LC-ESI-MS/MS) anal. of metanephrine and normetanephrine in blood plasma. Protein precipitation with methanol was found to be sufficient for sample preparation and pentafluorophenyl column provided adequate chromatog. separation A new cheaper and less labor-intensive approach is proposed where necessary quantitation limits are achieved through a sample preparation containing only protein precipitation and dilution of the sample extract Matrix effects for different sample preparation methods and the use of isotope-labeled internal standards were evaluated. Unusual interference to D₃-labeled internal standard of normetanephrine was discovered – signal of interfering compound increased while the matrix effects were reduced by dilution, e.g. dilution eliminates matrix suppression on interfering compound The results stress the need to monitor interfering compounds and evaluate matrix effects at every step of method development. Matrix effects and interferences can be different for analytes and their corresponding isotopically labeled internal standards This means that the use of isotopically labeled internal standards cannot guarantee accuracy of obtained results. New method allows quantification of the low nanomolar concentrations of metanephrine and normetanephrine in plasma samples.

Min, Xiao-Long;Zhang, Xiu-Lian;Yi, Wenbin;He, Ying research published 《 Bronsted acid-enhanced copper-catalyzed atroposelective cycloisomerization to axially chiral arylquinolizones via dearomatization of pyridine》, the research content is summarized as follows. Herein, the enantioselective synthesis of axially chiral arylquinolizones through an intramol. atroposelective cycloisomerization was reported. The reaction proceeds via the Bronsted acid-enhanced dearomatization of pyridine by a copper catalyst that allows for the formation of the desired products in excellent yields and enantioselectivities. The utility of this methodol. was illustrated by a synthesis on gram scale production and transformation of the products into chiral thiourea catalysts. Mechanistic studies demonstrate that Bronsted acid plays a significant role in promoting the reactivity of the reaction, while both the steric and electronic effects of aryl substituents in substrate play a role in controlling the stereoselectivity.

Here, a series of 1H-pyrazolo-[3,4-b]pyridine-4-carboxylic acid derivatives has been prepared in order to examine the structure-activity relationships (SAR). SAR studies clearly indicated that the steric bulkiness of the substituent on 1H-pyrazolo-[3,4-b]pyridine ring, the position of the distal hydrophobic tail part, and the distance between the distal hydrophobic tail part and the acidic head part are critical for hPPARα agonistic activity. These SAR results are somewhat different from those reported for fibrate-class hPPARα agonists. A representative compound (II) was as effective as fenofibrate in reducing the elevated plasma triglyceride levels in a high-fructose-fed rat model.

Type-1 ryanodine receptor (RyR1) is a calcium-release channel localized on sarcoplasmic reticulum (SR) of the skeletal muscle, and mediates muscle contraction by releasing Ca²⁺ from the SR. Genetic mutations of RyR1 are associated with skeletal muscle diseases such as malignant hyperthermia and central core diseases, in which over-activation of RyR1 causes leakage of Ca²⁺ from the SR. We recently developed an efficient high-throughput screening system based on the measurement of Ca²⁺ in endoplasmic reticulum, and used it to identify oxolinic acid (1) as a novel RyR1 channel inhibitor. Here, we designed and synthesized a series of quinolone derivatives based on 1 as a lead compound Derivatives bearing a long alkyl chain at the nitrogen atom of the quinolone ring and having a suitable substituent at the 7-position of quinolone exhibited potent RyR1 channel-inhibitory activity. Among the synthesized compounds, 14h showed more potent activity than dantrolene, a known RyR1 inhibitor, and exhibited high RyR1 selectivity over RyR2 and RyR3. These compounds may be promising leads for clin. applicable RyR1 channel inhibitors.
