Page/Page column 45; 48-49, (2021/05/15)
The present invention relates to divalent compounds binding to LecA. The compounds are useful to block biofilm formation of Pseudomonas aeruginosa. The invention further relates to pharmaceutical compositions comprising these compounds and to therapeutic methods and uses of these compounds, in particular to therapeutic methods and uses for the treatment of Pseudomonas aeruginosa infections in a subject. The invention also relates to imaging of infections, such as biofilms produced by Pseudomonas aeruginosa, by using these divalent compounds.

The highly rigid and planar scaffolds with π-conjugated systems have been widely considered to be indispensable for β-amyloid (Aβ) binding ligands. In this study, a library of diphenoxy compounds with different types of more flexible linkers as Aβ ligands were synthesized and evaluated. Most of them displayed good affinity (Ki1-42aggregates, and some ligands even showed values of Kiless than 10 nM. Structure-activity relationship analysis revealed that modification on the linkers or substituents tolerated great flexibility, which challenged the long-held belief that rigid and planar structures are exclusively favored for Aβ binding. Three ligands were labeled by iodine-125, and they exhibited good properties in vitro and in vivo, which further supported that this flexible scaffold was potential and promising for the development of Aβ imaging agents.

In this article, we are prepared that the liquid crystal dimers have aromatic-ester type mesogenic units or aromatic-Schiff base type mesogonic units and confirmed by 1H-NMR spectrometry. The mesomorphic and optical properties of the resultant dimers were studied by differential scanning calorimetry and polarizing optical microscopy.

A new series of macrocyclic compounds with one or two Troeger base skeletons has been synthesized by condensing mono-, di-, tri-, and teraethyleneglycol bis(p-aminophenoxy) ethers with formalin in the presence of concentrated hydrochloric acid in ethanol at room temperature for 13 days. This simple one-step cyclization provided 19 in remarkably high yield (46%) and 17, 18, and 20 in yields reflecting the strain of the rings and statistical factors. Complexation with lithium thiocyanate was observed for 20, the structure of which was elucidated by X-ray crystallography.
Bis-(4-isocyanatophenoxy)-alkanes and a process for the production thereof
-
, (2008/06/13)
Bis-(4-isocyanatophenoxy)-alkanes corresponding to the formula STR1 in which R represents a divalent, saturated aliphatic hydrocarbon radical having from 2 to 6 carbon atoms with at least two carbon atoms between the two ether oxygen atoms, and R' represents hydrogen or a methyl group with R' being the same on both rings, are produced by phosgenating the corresponding diamine or an adduct of the corresponding diamine. These diisocyanates are particularly useful in the production of isocyanate addition products having outstanding physical and mechanical properties.
