Macrocyclic Versus Linear Gadolinium Chelates

Macrocyclic Versus Linear Gadolinium Chelates.

T he article “High signal intensity in the dentate nucleus and globus pallidus on unenhanced T1weighted images: evaluation of the macrocyclic gadolinium-based contrast agent gadobutrol” by Radbruch et al provides critical new information regarding gadolinium deposition in the dentate nucleus. The conclusion, from a study of 30 patients, is that no signal intensity increase is seen with gadobutr...

Analytical interference in plasma iron determination reveals gadolinium vs. iron transmetallation with linear gadolinium chelates

Molecular nanotechnologies of gelatin-immobilization using macrocyclic metal chelates

This article is a review of recent developments in the self-assembled nanostructures based on chelate coordination compounds. Molecular nanotechnologies of self-assembly of 3d-element aza- and thiazametalmacrocyclic complexes that happen in nanoreactors on the basis of metal hexacyanoferrate(II) gelatin-immobilized matrix under their contact with water solutions containing various (N,O,S)-donor...

Phosphorescence of gadolinium(III) chelates under ambient conditions

The gadolinium(III) chelates Gd(dtpaH2), Gd(hfac)3, Gd(tta)3 and Gd(qu)3 with dtpa1⁄4 1,1,4,7,7-diethylenetriaminepentaacetate, hfac1⁄4 hexafluoroacetylacetonate, tta1⁄4 thenoyltrifluoroacetonate and qu1⁄4 8-quinolinolate (or oxinate) show a phosphorescence under ambient conditions. While the UV emission of Gd(dtpaH2) at kmax 1⁄4 312 nm comes from a metal-centered ff state, the bluish (kmax 1⁄4...
