“Click” on PLGA-PEG and hyaluronic acid: Gaining access to anti-leishmanial pentamidine bioconjugates

2017

Pentamidine (Pent), an antiparasitic drug used for the treatment of visceral leishmaniasis, has been modified with terminal azide groups and conjugated to two different polymer backbones (PLGA-PEG [PP] copolymer and hyaluronic acid [HA]) armed with alkyne end-groups. The conjugation has been performed by Copper Catalyzed Azido Alkyne Cycloaddition (CuAAC) using CuSO4 /sodium ascorbate as metal source. The novel PP-Pent and HA-Pent bioconjugates are proposed, respectively, as non-targeted and targeted drug delivery systems against Leishmania infections. Moreover, Pent has been encapsulated into PP nanoparticles by the oil-in-water emulsion method, with the aim to compare the biological activ…

Study of [2-(2’-pyridyl)imidazole] complexes to confirm two main characteristic thermoanalytical behaviors of transition metal complexes based on imi…

2016

Abstract Imidazole derivative ligands are recognized as useful models for biomimetic complexes. Among the inorganic–organic hybrid complexes, those with derivatives of imidazole heterocyclic N-donor ligands are interesting for their framework. In previous studies of complexes with imidazole derivative ligands, our group reported two main thermally induced decomposition behaviors supporting two different systematic decomposition trends. In this work, one of these characteristic decomposition mechanisms was again found. The final goal of these serial studies is the possibility to provide, by the experimental evidences, a prediction model of thermal stability and decomposition typical behavior…
