Fluorescence studies on new potential antitumoral 1,3-diarylurea derivatives in the thieno3,2-bpyridine series encapsulated in magnetoliposomes

摘要

Magnetic nanoparticles of magnetite and of nickel core with silica shell were prepared and either covered with a lipid bilayer or entrapped in liposomes, forming magnetoliposomes. New potential antitumoral 1,3-diarylurea derivatives of thieno[3,2-b]pyridines were then encapsulated in liposomes and magnetoliposomes and their photophysical behavior was investigated.
