Pérez Ortiz, Magdalena; Zapata Urzua, Claudio; Acosta, Gerardo A.; Álvarez Lueje, Alejandro; Albericio, Fernando; Kogan Bocian, Marcelo (Elsevier, 2017)In this work, the potential application of gold nanoparticles for GLP-1 analogues delivery was studied. For this purpose, the original sequence of the incretin GLP-1 was slightly modified in the C-terminal region by adding ...

Núñez Vergara, Luis; Matus, C.; Álvarez Lueje, Alejandro; Cassels Niven, Bruce; Squella Serrano, Juan (VCH Publishers. Inc., 1994)The cyclic voltammetric characteristics of two nitroamphetamine derivatives (2-nitro-4,5dimethoxyamphetamine and 2-nitro-4,5-methylenedioxyamphetamine) have been investigated in different media. In mixed media (aqueous ...
