METHOD FOR PREPARING GADOBUTROL

The present invention provides a novel method for preparing high-purity gadobutrol or hydrates thereof. The preparation method of the present invention can have an advantage of simplifying a process by forming a gadolinium complex in-situ without purification of a butrol intermediate and omitting a resin purification process unlike a conventional method for synthesizing gadobutrol. In addition, the preparation method of the present invention can be used to produce high-purity gadobutrol or hydrates thereof at a high yield only through the simple process as above, and thus can be useful in mass production.

Targeted Near-Infrared Imaging by Metal-Organic Frameworks
20210311041 · 2021-10-07 ·

Metal-organic frameworks (MOFs) comprising amines on the organic linker can be used for cell targeting. In particular, primary amine groups represent one of the most versatile chemical moieties for conjugation to biologically relevant molecules, including antibodies and enzymes. Different chemical conjugation schemes can be used to conjugate biological molecules to the amino functionality on the organic linker. For example, carbodiimide chemistry can be used to link a primary amine to available carboxyl groups on the protein. For example, sulfhydryl crosslinking chemistry can be used via Traut's reagent scheme. As a demonstration of the invention, the ability of EpCAM antibody-targeted MOFs to bind to a human epithelial cell line (A549), a common target for imaging studies, was confirmed with confocal microscopy.

Also provided are pharmaceutical compositions, kits and methods of in vivo imaging.

CHIRAL CYCLEN COMPOUNDS AND THEIR USES
20210283278 · 2021-09-16 ·

The present invention relates to the preparation of a series of chiral DOTA, DO3A, DO2A, DO1A, cyclen and their metal complexes, which display properties superior to those of previous DOTA-based compounds, and hence are potentially valuable as a platform for diagnostic applications. The chiral DOTAs reveal a high abundance of twisted square antiprism (TSA) geometry favoring them to be used as potential MRI contrast agents, whereas their rapid labelling properties at mild conditions make them excellent candidates for use as radiometal chelators.
