Hydrogen bond mediated partially miscible poly(N-acryloyl piperidine)/poly(acrylic acid) blend with one glass transition temperature

In this work, we have systematically studied the miscibility and phase structure of a hydrogen-bonded polymer blend composed of short rigid poly(N-acryloyl piperidine) (PAP) and long flexible poly(acrylic acid) (PAA). Ultrathin PAP/PAA blend films with various compositions were prepared by solution-casting method. It was found that the spin-coated blend films had distinct surface features with many protuberant domains that can be extracted by toluene. Composition analysis of the isolated protrusion domains and matrix domains revealed that PAP/PAA blend is a partially miscible system with PAP-rich protrusion phase (dispersed phase) and PAA-rich matrix phase. The hydrogen-bonding interaction between the amide carbonyl of PAP and hydroxyl of PAA (O = C center dot center dot center dot H-O) was found to account for the partial miscibility of these two components. Interestingly, only one positively shifted glass transition temperature (T-g) was detected for this blend. This behavior is very different from other reported partially miscible polymer blends, in which two inward shifted TgS are usually observed. Thermal analysis further disclosed that TgS of PAP-rich dispersed phase and PAA-rich matrix phase are very close to each other, thus merged into one broad T-g presented in the blend. The close TgS of these two phases is attributed to the strong hydrogen-bonding interaction between PAP and PAA, which surpasses the compositional difference between them. At high PAP concentrations (above 60 mol percent), the separation of excess PAP in dispersed phase contributed to the appearance of a second T-g that corresponds to that of PAP. Such phase behavior was further confirmed in the free-standing films of PAP/PAA blends.

Synthesis of alpha-hydroxyalkyl dehydroazepanes via catalytic enantioselective borylative migration of an enol nonaflate

A Pd-catalyzed borylative migration methodology for cyclic enol perfluorosulfonates was applied to the synthesis of the corresponding 7-membered, azepane ring system. Throughout the optimization, it was shown that the reaction is sensitive to the nitrogen protecting group as well as the type of base and solvent. The resulting cyclic allylboronate reacts stereoselectively with aldehydes for the synthesis of novel alpha-hydroxyalkyl dehydroazepanes in good yield and enantioselectivity over two steps. We highlight the utility of this methodology with an efficient synthesis of the de novo 7-membered ring analogue of the piperidine alkaloid beta-conhydrine. (C) 2018 Elsevier Ltd.

The heterocyclic compound Tempol inhibits the growth of cancer cells by interfering with glutamine metabolism

Tempol (4-hydroxy-2,2,6,6-Tetramethylpiperidine-1-oxyl, TPL), a nitroxide compound, inhibits proliferation and increases the vulnerability of cancer cells to apoptosis induced by cytotoxic agents. However, the molecular mechanism of TPL inhibiting cancer cell proliferation has not been fully understood. In this study, we evaluated the metabolic effect of TPL on cancer cells and explored its cancer therapeutic potential. Extracellular flow assays showed that TPL inhibited cellular basal and maximal oxygen consumption rates of mitochondrial. C-13 metabolic flux analysis showed that TPL treatment had minimal effect on glycolysis. However, we found that TPL inhibits glutamine metabolism by interfering with the oxidative tricarboxylic acid cycle (TCA) process and reductive glutamine process. We found that the inhibitory effect of TPL on metabolism occurs mainly on the step from citrate to alpha-ketoglutarate or vice versa. We also found that activity of isocitrate dehydrogenase IDH1 and IDH2, the key enzymes in TCA, were inhibited by TPL treatment. In xenograft mouse model, TPL treatment reduced tumor growth by inhibiting cellular proliferation of xenograft tumors. Thus, we provided a mechanism of TPL inhibiting cancer cell proliferation by interfering with glutamine utilization that is important for survival and proliferation of cancer cells. The study may help the development of a therapeutic strategy of TPL combined with other anticancer medicines.

2-Amino-5-(cyanomethylsulfanyl)-1H-pyrroles from Propargylamines, Isothiocyanates, and Bromoacetonitrile by One-Pot Synthetic Protocol

Tertiary propargylamines (such as N,N-dialkylpropargylamines, N-propargylpyrrolidine, -piperidine, and -morpholine), isothiocyanates, and bromoacetonitrile have been shown to be readily available building blocks for the highly selective one-pot construction of rare-functionalized pyrroles, namely so far inaccessible 1-substituted 2-amino-5-(cyanomethylsulfanyl)-1H-pyrroles, in up to 92 % yield. This highly efficient and operationally simple approach includes the initial formation of lithium but-2-ynimidothioate (adduct of monolithiated propargylamine and isothiocyanate), its transformation into potassium buta-2,3-dienimidothioate under the action of the t-BuOK/DMSO system (through acetylene-allene isomerization and the exchange by cations), intramolecular cyclization into potassium thienylamide (at <= 15 degrees C), followed by its re-cyclization into potassium pyrrolylsulfide at a higher temperature (45-60 degrees C), and the final S-alkylation of the latter with bromoacetonitrile. The total reaction time is 45-60 min.

2-Indolinone Derivatives as Potent Urease Inhibitors

Background: 2-Indolinone is a bicycle, heterocyclic compound analogous of indole skeleton containing a carbonyl group at 2-position of the 5-membered ring. Recently, different biological evaluations of oxindole derivatives have been reported. A variety of compounds with oxindoles moiety exhibit useful pharmaceutical properties like anti-inflammatory, anti-bacterial, anticancer, anti-proliferative, anti-hypertensive, anti-HIV and anti-convulsant activities. Methods: In the present study, fifteen 6-chloro-3-oxindole derivatives (1-15) were screened for urease inhibitory activity. The binding mode of the synthesized compounds was studied by molecular docking and found good results. 6-Chloro-3-oxindole derivatives 1-15 were synthesized from 6-chlorooxindole by refluxing with different aromatic aldehydes in ethanol in the presence of piperidine in high yields. Docking was carry out of the ligands into HCV NS3/4A protein. The software package MOE (Molecular Operating Environment) was used for docking. Results: Our present study has shown that compound 6 (IC50 = 13.34 +/- 1.75 mu M), 2 (IC50 = 16.67 +/- 1.73 mu M), and 5 (IC50 = 17.85 +/- 2.21 mu M) were found to be the most potent urease inhibitors as compared to the standard thiourea (IC50 = 21.1 +/- 0.11 mu M). Conclusion: Our present study has shown that Compounds 6 (IC50 = 13.34 +/- 1.75 mu M), 2 (IC50 = 16.67 +/- 1.73 mu M), and 5 (IC50 = 17.85 +/- 2.21 mu M) were found to be the most potent urease inhibitors as compared to the standard thiourea (IC50 = 21.1 +/- 0.11 mu M). These may serve as lead compounds for better urease inhibitors after fine tuning in the structure and further studies in future.

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.

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.
