Aqueous solutions of triblock copolymers used as the media affecting the magnetic relaxation properties of gadolinium ions trapped by metal-oxide nanostructures

Elistratova J.; Akhmadeev B.; Korenev V.; Sokolov M.; Nizameev I.; Ismaev I.; Kadirov M.; Sapunova A.; Voloshina A.; Amirov R.; Mustafina A. (2019)

© 2019 Elsevier B.V. The present work introduces the optimization of the oxidative degradation, complex formation and aggregation of the water-soluble metal oxide nanostructures (the so-called keplerates) [{W6O21(H2O)5(O ...
Nanoscale hydrophilic colloids with high relaxivity and low cytotoxicity based on Gd(III) complexes with Keplerate polyanions

Elistratova J.; Akhmadeev B.; Gubaidullin A.; Korenev V.; Sokolov M.; Nizameev I.; Stepanov A.; Ismaev I.; Kadirov M.; Voloshina A.; Mustafina A. (2017)

© The Royal Society of Chemistry and the Centre National de la Recherche Scientifique. The work introduces for the first time Mo-132-type Keplerates (Kp) and Gd 3+ ions as a basis for the one-pot synthesis of aqueous ...
One-pot embedding of iron oxides and Gd(III) complexes into silica nanoparticles—Morphology and aggregation effects on MRI dual contrasting ability

Fedorenko S.; Stepanov A.; Zairov R.; Kaman O.; Amirov R.; Nizameev I.; Kholin K.; Ismaev I.; Voloshina A.; Sapunova A.; Kadirov M.; Mustafina A. (2018)

© 2018 Elsevier B.V. The present work introduces one-pot synthetic route to join ultra-small iron oxides (6 nm) with Gd(III) complexes in small (∼30 nm) silica nanoparticles with high longitudinal and transverse relaxivity ...
Six-membered cyclic semiaminal as intermediate in the synthesis of thiazoles from thiosemicarhazide and α-haloketones

Mamedov V.; Berdnikov E.; Valeeva V.; Ismaev I.; Rizvanov I.; Antokhina L.; Nuretdinov I.; Chernov P. (1993)

Cyclization of thiosemicarbazide with methyl 3-chloro-2-oxo-3-phenylpropionate in MeCN results in 5-hydroxy-2-imino-5-methoxycarbonyl-6-phenylperhydro-1,3,4-thiadiazine. The structure of the product has been confirmed using ...
T<inf>2</inf>- and T<inf>1</inf> relaxivities and magnetic hyperthermia of iron-oxide nanoparticles combined with paramagnetic Gd complexes
