Pivotal Role of the Basic Character of Organic and Salt Catalysts in C-N Bond Forming Reactions of Amines with CO2

Paul Joseph Dyson, Martin Hulla

Organocatalysts promote a range of C-N bond forming reactions of amines with CO2. Herein, we review these reactions and attempt to identify the unifying features of the catalysts that allows them to promote a multitude of seemingly unrelated reactions. Ana ...

Nature of Synergy between Bronsted and Lewis Acid Sites in Sn-Beta Zeolites for Polyoxymethylene Dimethyl Ethers Synthesis

Oliver Kröcher, Alimohammad Bahmanpour, Christophe Jean Baranowski

The role of Lewis and Bronsted acid sites and their potential synergy remains ambiguous for the production of polyoxymethylene dimethyl ethers (OME), which are suitable as a Diesel substitute. Here, this synergistic effect was investigated by using a serie ...

Active Site-Induced Evolutionary Constraints Follow Fold Polarity Principles in Soluble Globular Enzymes

Matteo Dal Peraro, Luciano Andres Abriata

A recent analysis of evolutionary rates in >500 globular soluble enzymes revealed pervasive conservation gradients toward catalytic residues. By looking at amino acid preference profiles rather than evolutionary rates in the same data set, we quantified th ...

Can Mutational Analysis Be Used To Assist Structure Determination of Peptides?

Thomas Rizzo, Valeriu Scutelnic, Chiara Masellis, Liudmila Voronina

Mutational analysis is widely used to study the relationship between sequence and structure of proteins and peptides. It is often assumed that substituting a proline with another amino acid "locks" the peptide bond in the trans conformation, allowing only ...

Anti-fibrotic effect of ketoprofen-grafted alginate microcapsules in the transplantation of insulin producing cells

Sandrine Gerber, Daniel Ortiz Trujillo, François Rémi Pierre Noverraz, Luca Szabó

The controlled release of small molecular modulators of the immune response from hydrogel microspheres (MS) used for cell immobilization is an attractive approach to reduce pericapsular fibrotic overgrowth (PFO) after transplantation. Ketoprofen is a well- ...

Development of cyclic peptide inhibitors of coagulation factor XII and matrix metalloproteinase 2

Jonas Alfred Karl Wilbs

Peptides represent a promising molecular class for drug development. They combine several strengths of small molecules (e.g. efficient tissue diffusion, low immunogenicity and access to chemical synthesis) and key properties of biologics such as monoclonal ...

Peptide Bond Ultraviolet Absorption Enables Vibrational Cold-Ion Spectroscopy of Nonaromatic Peptides

Vladimir Kopysov, Aleksandr Pereverzev

Peptide-bond VUV absorption is inherent to all proteins and peptides. Although widely exploited in top-down proteomics for photodissociation, this absorption has never been spectroscopically characterized in the gas phase. We have measured VUV/UV photofrag ...

A novel psychoanalytical approach: An electrochemical ligand-binding assay to screen antipsychotics

Sandro Carrara, Tugba Kilic

Schizophrenia treatment may see a paradigm shift due to development of new atypical antipsychotic drugs (APDs), with better tolerability due to more selective dopamine (DA) receptor blockade. Monitoring of these APD candidates in biological fluids is of gr ...

Glycotargeting therapeutics

Jeffrey Alan Hubbell, David Scott Wilson

Several embodiments of the present disclosure relate to therapeutic compositions configured to target the liver of a subject and that are useful in the treatment or prevention of one or more of transplant rejection, autoimmune disease, food allergy, and im ...

Benign synthesis of quinolinecarboxamide ligands, H(2)bqbenzo and H(2)bqb and their Pd(II) complexes: X-ray crystal structure, electrochemical and antibacterial studies

Farzaneh Fadaei Tirani

Two carboxamide ligands, H(2)bqbenzo {3,4-bis(2-quinolinecarboxamido)benzophenone} and H(2)bqb {N,N-bis[(2-quinolinecarboxamide)-1,2-benzene]}, have been prepared using tetrabutylammonium bromide as an environmentally benign reaction medium. Two new Pd(II) ...
