Lipophilic chelates and their use in imaging

The invention relates to chelate compounds which can be used in MRI, the chelates being intended to be conveyed by lipophilic transporters, such as lipid nanoparticles or liposomes. The invention also relates to compounds comprising, in association, these chelates and these transporters, if appropriate connected via chemical bonding groups, and to their use in diagnostic imaging, it being possible for this association additionally to comprise biological targeting markers, denoted biovectors.

Regio-selective synthesis of polyazacyclophanes incorporating a pendant group as potential cleaving agents of mRNA 5′-cap structure

A terpyridine or an imidazole unit has been tethered to an N-protected polyazacyclophane to give the appropriate N-monofunctionalized polyazacyclophane. After mild deprotection, four polyazacyclophanes incorporating a pendant group were obtained in satisf

Oligomers of gadolinium chelates, their applicationascontrast products in magnetic resonance imaging and their synthesis intermediates

The invention relates to high-relaxivity macrocyclic gadolinium chelate oligomers of formula [in-line-formulae]W-(A)m[/in-line-formulae] in which W, A and m are as defined in claim 1, and their use as a blood pool contrast product for magnetic resonance imaging.

Regioselective synthesis of N-functionalized 12-membered azapyridinomacrocycles bearing trialkylcarboxylic acid side chains

Selective protection of primary amine moieties of diethylenetriamine by 2-nitrophenylsulfonyl chloride followed by alkylation of the central N atom generates functionalized disulfonamide building blocks. When reacted with 2,6-bis(bromomethyl)pyridine following the Richman-Atkins methodology, such compounds yield the corresponding pyridine-containing azamacrocycles. Smooth removal of the N-sulfonyl groups provides versatile azamacrocyclic intermediates with transannular secondary amine functions. Subsequent N-alkylation regioselectively leads to tri N-functionalized 12-membered azapyridinomacrocycles bearing a sequence of N-acetate and N-propionate side chains.
