Effective antimicrobial drugs are the very core of modern medicine enabling successful prevention and treatment of infectious diseases. However, systemic misuse and overuse of antibiotics in human medicine, as well as in animal husbandry have led to widespread antibiotic-resistance, rendering many of these drugs ineffective. Therefore, there is an urgent need for new treatment options to conventional ...

SUMMARY A new procedure has been developed for the synthesis of barbituric acid derivatives. The reactions were performed under solvent free conditions without any catalyst. Employing this synthetic route, a large number of chalconoids and 5-,6-, and 7-membered heterocycles have been successfully synthesized in a very short time. The chalconoids have been synthesized from a barbituric derivative ...

We here report the preparation of a new 2,6,8-trisubstituted bicyclic tripeptidomimetic scaffold through TFA-mediated cyclization of a linear precursor containing three side chains. The introduction of a triphenylmethyl-protected thiol into carboxylic acid containing building blocks through sulfa Michael additions onto α,β-unsaturated hexafluoroisopropyl esters is described. The stereoselectivity ...

Nanoparticles are usually defined as particles in a size range of 1-100 nm, and these particles often have different properties than the non-nanoscale material of the same chemical composition. In recent years, as the interest and use of nanoparticles has increased and so has the interest in understanding their behaviour, impact and fate in the environment. In the last decades, there has been special ...

Breitfussins are a group of a closely related heterocyclic compounds. They consist of a tetracyclic structure with an indole, an oxazole and a pyrrole. The breitfussins exhibit interesting biological activity and analogues synthesis and biological evaluation is ongoing. Phorbazoles have a structural similarity with breitfussins in which a phenol replaces the indole. As a part of this, synthesis of ...

Oppgaven omhandler syntesen av mulige metallo-beta-lactamaser inhibitorer.

Cyclometalated Au(III) complexes are of interest due to their catalytic, medicinal, and photophysical properties. Herein, we describe the synthesis of derivatives of the type (N,C)Au(OAcF)2 (OAcF = trifluoroacetate) and (N,C,C)AuOAcF by a cyclometalation route, where (N,C) and (N,C,C) are chelating 2-arylpyridine ligands. The scope of the synthesis is explored by substituting the 2-arylpyridine core ...

XTH er en gruppe enzymer som ble oppdaget tidlig på 90 tallet og muligens er involvert i Cuscuta infeksjonen av tomater. En nylig studie gjort ved arktisk og marin biologi UIT viser at Brilliant Blue R250 fungerer som en god inhibitor mot disse enzymene. I dette prosjektet ble det fokusert på å syntetisere strukturelt like molekyler for å potensielt øke vannløseligheten og inhibitoraktiviteten. ...

A method was developed for synthesizing and isolating two DRPs, with varying levels of success affected by difficulties in the purification process and human error. However, it has shed light on some of the difficulties that may occur and suggestions on how they could be improved. The method developed structure elucidation through sequential reduction and alkylation of the disulfide bridges proved ...

Abstract: Herein, we describe the synthesis, biological evaluation and molecular docking of the selective PPARb/ d antagonist (4-methyl-2-(4-(trifluoromethyl)phenyl)-N-(2-(5-(trifluoromethyl)-pyridin-2-ylsulfonyl) ethyl)thiazole-5-carboxamide)), CC618. Results from in vitro luciferase reporter gene assays against the three known human PPAR subtypes revealed that CC618 selectively antagonizes ...
