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.

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

Discovery and Lead-Optimization of 4,5-Dihydropyrazoles as Mono-Kinase Selective, Orally Bioavailable and Efficacious Inhibitors of Receptor Interacting Protein 1 (RIP1) Kinase

RIP1 kinase regulates necroptosis and inflammation and may play an important role in contributing to a variety of human pathologies, including inflammatory and neurological diseases. Currently, RIP1 kinase inhibitors have advanced into early clinical trials for evaluation in inflammatory diseases such as psoriasis, rheumatoid arthritis, and ulcerative colitis and neurological diseases such as amyotrophic lateral sclerosis and Alzheimer’s disease. In this paper, we report on the design of potent and highly selective dihydropyrazole (DHP) RIP1 kinase inhibitors starting from a high-throughput screen and the lead-optimization of this series from a lead with minimal rat oral exposure to the identification of dihydropyrazole 77 with good pharmacokinetic profiles in multiple species. Additionally, we identified a potent murine RIP1 kinase inhibitor 76 as a valuable in vivo tool molecule suitable for evaluating the role of RIP1 kinase in chronic models of disease. DHP 76 showed efficacy in mouse models of both multiple sclerosis and human retinitis pigmentosa.

7-(2-Aminomethyl-1-azetidinyl)-4-oxoquinoline-3-carboxylic acids as potent antibacterial agents: Design, synthesis, and antibacterial activity

2-Aminomethyl-1-azetidinyl, -1-pyrrolidinyl, and -1-piperidinyl groups were designed as novel C-7 substituents for potential antibacterial quinolone agents. Of the three substituents, the 2-aminomethyl-1-azetidinyl group (compound 12a) was found to be the most favorable for enhancing the activity of the 6,8-difluoroquinoline molecule 12. Therefore the 2-aminomethyl-1- azetidinyl group was introduced into a variety of quinolines (giving 24 – 26a, and 28a) and naphthyridines (giving 31a and 32a). Through optical resolution of 1-benzylazetidine-2-carboxamide (19) and chiral synthesis of its R-isomer, both enantiomers of 2-aminomethyl-1-azetidinyl quinolines 12a and 24 – 26a were also prepared. The most active of all the compounds was 5- amino-6,8-difluoroquinoline (R)-26a. The activity of (R)-26a was more potent than those of the corresponding 1-piperazinyl derivative (3) and sparfloxacin (1), and was comparable to those of the corresponding 3-amino-1-pyrrolidinyl (4), 3-aminomethyl-1-pyrrolidinyl (5), and 3-amino-1-azetidinyl (6) derivatives.

Polymerization- and solvent-triggered cooperativity between copper(II) ions in the catalysis of the hydrolysis of amino esters by pyridine-based ligands

Polymeric (2) and oligomeric (4, 5) materials made of repeating units of 2,6-diaminomethylpyridine and 4,4?-diphenylmethane have been synthesized with the number of monomeric units (n) ranging from 2 to 29. In 1:1 DMSO/water solutions, these materials are fully soluble and strongly bind CuII ions. The complexes catalyze to different extents the hydrolysis of the p-nitrophenyl esters of alpha-, beta-, and gamma-amino acids. Only CuII complexes of polymeric 2 (n ? 10) are more effective catalysts than free CuII ions in the cleavage of beta-amino esters. Such enhanced reactivity, which in the case of beta-alanine p-nitrophenyl ester (beta-AlaPNP) amounts to almost two orders of magnitude when the comparison is made with the CuII complex of monomeric ligand (N,N’-benzyl)-2,6-aminomethylpyridine (3), is observed in 1:1 (v/v) DMSO/H2O only when a certain degree of polymerization is reached (6 < n < 10). In 1:1 (v/v) CH3CH2OH/H2O the kinetic benefits of the complexes of polymer 2 (n = 10) diminishes and vanishes in 9:1 (v/v) CH3CH2OH/H2O. Analysis of rate data suggests that two neighboring CuII ions bound to the polymeric ligands cooperate for the occurrence of the hydrolytic process: one of them coordinates the amino group of the substrate so that the carbonyl of the carboxylate faces the second metal ion which delivers a bound hydroxyl acting as the nucleophilic species. The selectivity toward beta-amino ester is likely associated with a rather rigid conformation of these metallopolymers which places two metal centers at the appropriate distance one from the other. It is suggested that the onset of the metal ion cooperativity is connected to a conformational change of the metallopolymer from an extended to a globular structure, likely triggered by hydrophobic forces.
