Hypothalamic JNK1-hepatic fatty acid synthase axis mediates a metabolic rewirin...
Ferreira, Vitor; Folgueira, Cintia; García-Altares, María; Guillén, Maria; Ruíz-Rosario, Mónica; DiNunzio, Giada; Garcia-Martinez, Irma; Alen, RosaOlanzapine (OLA), a widely used second-generation antipsychotic (SGA), causes weight gain and metabolic alterations when administered orally to patients. Recently, we demonstrated that, contrarily to the oral treatment which induces weight gain, OLA administered via intraperitoneal (i.p.) in male mice resulted in body weight loss. This protection was due to an increase in energy expenditure (EE) through a mecha...
Dual Imaging Gold Nanoplatforms for Targeted Radiotheranostics
Silva, Francisco; Paulo, António; Pallier, Agnès; Même, Sandra; Tóth, Éva; Gano, Lurdes; Marques, Fernanda; Geraldes, Carlos F. G. C.Gold nanoparticles (AuNPs) are interesting for the design of new cancer theranostic tools, mainly due to their biocompatibility, easy molecular vectorization, and good biological half-life. Herein, we report a gold nanoparticle platform as a bimodal imaging probe, capable of coordinating Gd3+ for Magnetic Resonance Imaging (MRI) and 67Ga3+ for Single Photon Emission Computed Tomography (SPECT) imaging. Our AuNP...
Gold nanoparticles functionalised with fast water exchanging Gd3+ chelates: Lin...
Martins, J. A. R.; Ferreira, Paula M. T.; Geraldes, Carlos F. G. C.; Helm, Lothar; Prata, Maria I. M.; Rodrigues, Sérgio P. J.; Rodrigues, Tiago B.The relaxivity displayed by Gd3+ chelates immobilized onto gold nanoparticles is the result of complex interplay between nanoparticle size, water exchange rate and chelate structure. In this work we study the effect of the length of -thioalkyl linkers, anchoring fast water exchanging Gd3+ chelates onto gold nanoparticles, on the relaxivity of the immobilized chelates. Gold nanoparticles functionalized with Gd3...
Amide conjugates of the DO3A-N-(alpha-amino)propionate ligand: leads for stable...
Ferreira, Miguel Filipe Moreira Marques; Martins, André F.; Martins, Catarina I. O.; Ferreira, Paula M. T.; Tóth, Éva; Rodrigues, Tiago B.A novel synthetic methodology for preparing amide conjugates of the DO3A-N-(alfa-amino)propionate chelator is described, using the synthesis of the DO3A-N-(alfa-benzoylamido)propionate chelator as an illustrative example. The model Gd(DO3A-N-(alfa-benzoylamido)propionate) chelate displays accelerated water exchange, stability in a wide pH range and inertness towards transmetallation by Zn2+. The Gd(DO3A-N-(alaf...
