Conjugados poliméricos y su utilización como nanomedicinas anticancerígenas

Abstract

Independently of the discovery of new drugs for good established pharmacologic targets, the commitment of science with the society demands the development of macromolecular analogs, in order to improve the therapeutic possibilities of existing drugs, contributing to an increase on their biological activity and a greater specificity. Every time becomes more strongly the postulated that the application of nanotechnology in medicine is the key to obtain the necessary improvements in diagnosis and anticancer therapy [1]. In order to distinguish them from the other biotechnological products, such as proteins and antibodies; the nanodrugs have been defined as “… complex systems of nanometric scale, at least constituted by two components, being one of them a bioactive agent…” [2]. With several polymer-protein conjugates in the market and more than eleven polymer-drug conjugates in clinical trails; polymer therapeutics can be considered as the first polymeric nanomedicines [3]. It is important to make clear that although this article is focused on the use of polymeric conjugates as anticancerigenic agents, its clinical application is wider than. Other potential applications have been described for these nanomedicines, such as inmunomodulation, antiviral agents or drugs for enzymatic reconstruction, among others [3].

Independientemente del descubrimiento de nuevos fármacos para dianas farmacológicas bien establecidas, el compromiso de la ciencia con la sociedad demanda del desarrollo de análogos macromoleculares que mejoren las posibilidades terapéuticas de los fármacos existentes aportando una mayor actividad biológica y una mayor especificidad. Se postula, cada vez con más fuerza, que la aplicación de la nanotecnología a la medicina es la clave para conseguir las mejoras necesarias tanto en diagnosis como en terapia anticancerígeno [1]. Para poder distinguirlos de otros productos biotecnológicos como proteínas y anticuerpos, los nanofármacos han sido definidos como “... sistemas complejos de escala nanométrica constituidos al menos por dos componentes, siendo uno de ellos el agente bioactivo...” [2]. Con varios conjugados polímero-proteína en el mercado y más de 11 conjugados polímero-fármaco en fase clínica, los polímeros terapéuticos pueden ser considerados como una de las primeras nanomedicinas poliméricas [3]. Es importante mencionar que aunque este artículo se centra en el uso de conjugados poliméricos como anticancerígenos, su aplicación clínica es mucho más amplia habiendo sido descritos como posibles inmunomoduladores, agentes antivíricos o fármacos para reconstitución enzimát ica entre otros [3].
