Experimental and theoretical investigation of equilibrium absorption performance of CO2 using a mixed 1-dimethylamino-2-propanol (1DMA2P) and monoethanolamine (MEA) solution

Reliable equilibrium solubility data and consistent thermodynamic models for CO2 in novel amine solutions are necessary to design and simulate the CO2 capture process. In this study, the first experimental data for the equilibrium solubility of CO2 in a mixed 1-dimethylamino-2-propanol (1DMA2P) and monoethanolamine (MEA) aqueous solution are reported. The experiments were performed over a CO2 partial pressure of 3?186 kPa, at a total concentration of 2.5 M, and at two different temperatures (313.15 and 333.15 K). The CO2 solubility data were measured using a static-synthetic method based on the material balance method. The extended-universal quasi-chemical (e-UNIQUAC) model was applied to predict the experimental data. The adjustable parameters were either obtained from the model or taken from the literature for experimental binary, ternary, and quaternary systems. Moreover, the species concentration in the liquid phase, activity coefficients, solution pH, and solution ionic strength were predicted. The experimental results show that the CO2 absorption capacity increases as the blend mole ratio of 1DMA2P/MEA increases. An acceptable error was obtained between the experimental data and the model-predicted values, with an absolute average relative deviation of 22.4%. The e-UNIQUAC model employed in this study can be used to simulate the CO2 absorption process by the 1DMA2P-MEA solution.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3040-44-6, help many people in the next few years.Application In Synthesis of 1-(2-Hydroxyethyl)piperidine

Development of nonsymmetrical 1,4-disubstituted anthraquinones that are potently active against cisplatin-resistant ovarian cancer cells

A novel series of 1,4-disubstituted aminoanthraquinones were prepared by ipso-displacement of 1,4-difluoro-5,8-dihydroxyanthraquinones by hydroxylated piperidinyl- or pyrrolidinylalkyl-amino side chains. One aminoanthraquinone (13) was further derivatized to a chloropropyl-amino analogue by treatment with triphenylphosphine-carbon tetrachloride. The compounds were evaluated in the A2780 ovarian cancer cell line and its cisplatin-resistant variants (A2780/cp70 and A2780/MCP1). The novel anthraquinones were shown to possess up to 5-fold increased potency against the cisplatin-resistant cells compared to the wild-type cells. Growth curve analysis of the hydroxyethylaminoanthraquinone 8 in the osteosarcoma cell line U-2 OS showed that the cell cycle is not frozen, rather there is a late cell cycle arrest consistent with the action of a DNA-damaging topoisomerase II inhibitor. Accumulative apoptotic events, using time lapse photography, indicate that 8 is capable of fully engaging cell cycle arrest pathways in G2 in the absence of early apoptotic commitment. 8 and its chloropropyl analogue 13 retained significant activity against human A2780/cp70 xenografted tumors in mice.

Synthesis and pharmacological evaluation of novel isoquinoline N-sulphonylhydrazones designed as ROCK inhibitors

In this study, we synthesized a new congener series of N-sulphonylhydrazones designed as candidate ROCK inhibitors using the molecular hybridization of the clinically approved drug fasudil (1) and the IKK-beta inhibitor LASSBio-1524 (2). Among the synthesized compounds, the N-methylated derivative 11 (LASSBio-2065) showed the best inhibitory profile for both ROCK isoforms, with IC50 values of 3.1 and 3.8 muM for ROCK1 and ROCK2, respectively. Moreover, these compounds were also active in the scratch assay performed in human breast cancer MDA-MB 231 cells and did not display toxicity in MTT and LDH assays. Molecular modelling studies provided insights into the possible binding modes of these N-sulphonylhydrazones, which present a new molecular architecture capable of being optimized and developed as therapeutically useful ROCK inhibitors.

Bioactive metabolites from rare actinomycetes

New antibiotics are desperately needed to combat the increasing number of antibiotic resistant strains of pathogenic microorganisms. Natural products remain the most propitious source of novel antibiotics. It is widely accepted that actinobacteria are prolific producers of natural bioactive compounds. We argue that the likelihood of discovering a new compound having a novel chemical structure can be increased with intensive efforts in isolating and screening rare genera of microorganisms. Screening rare actinomycetes and their previously underrepresented genera from unexplored environments in natural product screening collections is one way of achieving this. Rare actinomycetes are usually regarded as the actinomycete strains whose isolation frequency is much lower than that of the streptomycete strains isolated by conventional methods. The relevance of the rare actinomycetes in this regard can also be demonstrated by the fact that many of the successful antimicrobial agents currently available in the market are produced by them. This chapter focuses on the bioactive secondary metabolites from rare actinomycetes with emphasis on their structures, relevant biological activities, source organisms, covering over 150 structures of different bioactive compounds produced by them with 84 citations. Its aim is to give the reader a brief view of the bioactive compounds from the rare actinomycetes and we wish to update our understanding of the potential of the rare actinomycetes by focusing on their biodiscovery potential. The emphasis is placed on new compounds discovered from these microorganims with bioactive potential. Copyright

Selective NR1/2B N-methyl-D-aspartate receptor antagonists among indole-2-carboxamides and benzimidazole-2-carboxamides

(4-Benzylpiperidine-1-yl)-(6-hydroxy-1H-indole-2-yl)-methanone (6a) derived from (E)-1 -(4-benzylpiperidin-1-yl)-3-(4-hydroxy-phenyl)-propenone (5) was identified as a potent NR2B subunit-selective antagonist of the NMDA receptor. To establish the structure-activity relationship (SAR) and to attempt the improvement of the ADME properties of the lead, a series of compounds were prepared and tested. Several derivatives showed low nanomolar activity both in the binding and in the functional assay. In a formalin-induced hyperalgesia model in mice, 6a and (4-benzylpiperidine-1-yl)-[5(6)-hydroxy-1H-benzimidazol-2- yl]-methanone (60a) were as active as besonprodil (2) after oral administration. A CoMS1A model was developed based on binding data of a series of indole- and benzimidazole-2-carboxamides.

Discovery of pteridin-7(8 H)-one-based irreversible inhibitors targeting the epidermal growth factor receptor (EGFR) kinase T790M/L858R mutant

The EGFR T790M variant is an important mutation, resulting in approximately 50% of the clinically acquired resistance to approved EGFR inhibitors. Starting with a previously reported pyrimidine-based EGFR inhibitor, a novel pteridin-7(8H)-one scaffold with a high 3D similarity was found and transformed into irreversible inhibitors of the EGFR T790M mutant. The most potent compounds, 3q and 3x, exhibited excellent enzyme inhibitory activities, with subnanomolar IC50 values for both the wild-type and T790M/L858R double mutant EGFRs, as well as potent cellular antiproliferative activities against both gefitinib-sensitive and -resistant cancer cell lines. The in vivo antitumor efficacy study demonstrated that compound 3x significantly inhibited tumor growth and induced tumor stasis in an EGFR-T790M/L858R-driven human nonsmall-cell lung cancer xenograft mouse model. This work demonstrated the utility of this sophisticated computational design strategy for fast 3D scaffold hopping with competitive bioactivities to meet an important clinical need.

Conformational switching of G-quadruplex DNA by photoregulation

Bend and stretch. . . bend and stretch. . . An azobenzene derivative was used to induce reversible stretching and folding of G-quadruplex DNA upon photoirradiation (see picture). The G-quadruplex formed in the presence of the trans isomer was dissociated by irradiation with UV light, and the resulting open oligomer was refolded into a G quadruplex under visible light. This nanodevice thus converts light directly into mechanical work. (Figure Presented).
