Rechargeable hydrogen storage system based on the dehydrogenative coupling of ethylenediamine with ethanol

A novel and simple hydrogen storage system was developed, based on the dehydrogenative coupling of inexpensive ethylenediamine with ethanol to form diacetylethylenediamine. The system is rechargeable and utilizes the same ruthenium pincer catalyst for both hydrogen loading and unloading procedures. It is efficient and uses a low catalyst loading. Repetitive reversal reactions without addition of new catalyst result in excellent conversions in both the dehydrogenation and hydrogenation procedures in three cycles. In support of the hydrogen economy: An efficient and simple homogeneous hydrogen carrier system was developed based on the dehydrogenative coupling of ethylenediamine with ethanol to form diacetylethylenediamine. The same ruthenium pincer catalyst is used for both hydrogen loading and unloading reactions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 473257-60-2, you can also check out more blogs about473257-60-2

Small-Molecule Inhibitors of the Programmed Cell Death-1/Programmed Death-Ligand 1 (PD-1/PD-L1) Interaction via Transiently Induced Protein States and Dimerization of PD-L1

Blockade of the PD-1/PD-L1 immune checkpoint pathway with monoclonal antibodies has provided significant advances in cancer treatment. The antibody-based immunotherapies carry a number of disadvantages such as the high cost of the antibodies, their limited half-life, and immunogenicity. Development of small-molecule PD-1/PD-L1 inhibitors that could overcome these drawbacks is slow because of the incomplete structural information for this pathway. The first chemical PD-1/PD-L1 inhibitors have been recently disclosed by Bristol-Myers Squibb. Here we present NMR and X-ray characterization for the two classes of these inhibitors. The X-ray structures of the PD-L1/inhibitor complexes reveal one inhibitor molecule located at the center of the PD-L1 homodimer, filling a deep hydrophobic channel-like pocket between two PD-L1 molecules. Derivatives of (2-methyl-3-biphenylyl)methanol exhibit the structures capped on one side of the channel, whereas the compounds based on [3-(2,3-dihydro-1,4-benzodioxin-6-yl)-2-methylphenyl]methanol induce an enlarged interaction interface that results in the open “face-back” tunnel through the PD-L1 dimer.

Selection of a potential diagnostic biomarker for HIV infection from a random library of non-biological synthetic peptoid oligomers

Non-biological synthetic oligomers can serve as ligands for antibodies. We hypothesized that a random combinatorial library of synthetic poly-N-substituted glycine oligomers, or peptoids, could represent a random ?shape library? in antigen space, and that some of these peptoids would be recognized by the antigen-binding pocket of disease-specific antibodies. We synthesized and screened a one bead one compound combinatorial library of peptoids, in which each bead displayed an 8-mer peptoid with ten possible different amines at each position (108 theoretical variants). By screening one million peptoid/beads we found 112 (approximately 1 in 10,000) that preferentially bound immunoglobulins from human sera known to be positive for anti-HIV antibodies. Reactive peptoids were then re-synthesized and rigorously evaluated in plate-based ELISAs. Four peptoids showed very good, and one showed excellent, properties for establishing a sero-diagnosis of HIV. These results demonstrate the feasibility of constructing sero-diagnostic assays for infectious diseases from libraries of random molecular shapes. In this study we sought a proof-of-principle that we could identify a potential diagnostic antibody ligand biomarker for an infectious disease in a random combinatorial library of 100 million peptoids. We believe that this is the first evidence that it is possible to develop sero-diagnostic assays ? for any infectious disease ? based on screening random libraries of non-biological molecular shapes.

Small-molecule inhibitors of the MDM2-p53 protein-protein interaction based on an isoindolinone scaffold

From a set of weakly potent lead compounds, using in silico screening and small library synthesis, a series of 2-alkyl-3-aryl-3-alkoxyisoindolinones has been identified as inhibitors of the MDM2-p53 interaction. Two of the most potent compounds, 2-benzyl-3-(4-chlorophenyl)-3-(3-hydroxypropoxy)-2,3- dihydroisoindol-1-one (76; IC50 = 15.9 ¡À 0.8 muM) and 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2, 3-dihydroisoindol-1-one (79; IC50 = 5.3 ¡À 0.9 muM), induced p53-dependent gene transcription, in a dose-dependent manner, in the MDM2 amplified, SJSA human sarcoma cell line.

Chemical Ligand Space of Cereblon

The protein cereblon serves as a substrate receptor of a ubiquitin ligase complex that can be tuned toward different target proteins by cereblon-binding agents. This approach to targeted protein degradation is exploited in different clinical settings and has sparked the development of a growing number of thalidomide derivatives. Here, we probe the chemical space of cereblon binding beyond such derivatives and work out a simple set of chemical requirements, delineating the metaclass of cereblon effectors. We report co-crystal structures for a diverse set of compounds, including commonly used pharmaceuticals, but also find that already minimalistic cereblon-binding moieties might exert teratogenic effects in zebrafish. Our results may guide the design of a post-thalidomide generation of therapeutic cereblon effectors and provide a framework for the circumvention of unintended cereblon binding by negative design for future pharmaceuticals.

Design, synthesis, and evaluation of benzofuran derivatives as novel anti-pancreatic carcinoma agents via interfering the hypoxia environment by targeting HIF-1alpha pathway

Pancreatic ductal adenocarcinoma (PDAC) is one of the most common type of pancreatic cancer, and has still been the medicinal mystery. New drugs and treatment strategies are urgently needed. In this study, 32 benzofuran derivatives are designed, synthesized and evaluated as potential agents against the pancreatic cancer. Among them, compound 9o with the best physicochemical and pharmacokinetic properties exhibited excellent cytotoxicity against many tumor cell lines. In vivo study showed that compound 9o dramatically suppressed the tumor growth of nude mice. Furthermore, compound 9o could affect the hypoxia environment through Hif-1alpha/VEGF pathway, resulting in the anti-angiogenic activity. These studies indicated that compound 9o was a promising candidate for the treatment of PDAC, deserving further studies.

Molecular recognition in the P2Y14 receptor: Probing the structurally permissive terminal sugar moiety of uridine-5?-diphosphoglucose

The P2Y14 receptor, a nucleotide signaling protein, is activated by uridine-5?-diphosphoglucose 1 and other uracil nucleotides. We have determined that the glucose moiety of 1 is the most structurally permissive region for designing analogues of this P2Y14 agonist. For example, the carboxylate group of uridine-5?-diphosphoglucuronic acid proved to be suitable for flexible substitution by chain extension through an amide linkage. Functionalized congeners containing terminal 2-acylaminoethylamides prepared by this strategy retained P2Y14 activity, and molecular modeling predicted close proximity of this chain to the second extracellular loop of the receptor. In addition, replacement of glucose with other sugars did not diminish P2Y14 potency. For example, the [5??]ribose derivative had an EC50 of 0.24 muM. Selective monofluorination of the glucose moiety indicated a role for the 2??- and 6??-hydroxyl groups of 1 in receptor recognition. The beta-glucoside was twofold less potent than the native alpha-isomer, but methylene replacement of the 1??-oxygen abolished activity. Replacement of the ribose ring system with cyclopentyl or rigid bicyclo[3.1.0]hexane groups abolished activity. Uridine-5?-diphosphoglucose also activates the P2Y2 receptor, but the 2-thio analogue and several of the potent modified-glucose analogues were P2Y14-selective.
