Abstract/OtherAbstract:
Nucleoside analogues, together with nucleobases and nucleotide analogues, are commonly used in the treatment of cancer and viral infections. In both cases, they act as antimetabolite agents and interfere with the synthesis of cellular or viral nucleic acids. However, the need of high doses due to the rapid elimination of these compounds, to their poor activation, and/or to their non-specific distribution, often leads to side effects and resistances. The present paper aims to review the different types of polymer nanoparticles which have been designed as drug delivery devices to address these issues. Thus, poly(alkylcyanoacrylate) nanoparticles have been demonstrated as potential carriers for antiviral nucleoside analogues, especially for anti-HIV agents, regarding both intravenous and oral routes. Nanoparticles based on polyesters such as poly(lactic acid) and poly(lactide-co-glycolide) have been used as nanocarriers for nucleosides analogues too, and especially for their ocular delivery. Albumin has shown interesting properties in the design of nanoparticles for the same application, but also for the oral administration of anticancer analogues. Finally, new hydrophilic nanoparticles consisting of cross-linked polymer network ('Nanogels') open the perspective to deliver nucleoside analogues within their active triphosphate form.
