Abstract
Actualmente, el uso de nanoestructuras con aplicación terapéutica para la administración y liberación de fármacos (e. g. sistemas micelares) está ampliamente extendido debido a sus propiedades únicas que las hacen indispensables en el ámbito biomédico y en otros diversos campos.
En este trabajo se describe el estudio sistemático de una serie de moléculas anfifílicas que forman micelas auto-replicantes, es decir, capaces de hacer copias de sí mismas. Nuestro sistema utiliza dos precursores reactivos que generan anfifilos peptídicos in situ capaces de ensamblar micelas que catalizan su propia síntesis, generando copias idénticas de sí mismas.
El estudio consistió en analizar de forma combinatoria una colección de precursores de distintos tamaños para, finalmente, identificar el anfifilo más pequeño necesario para la formación de micelas auto-replicantes.
Estos resultados contribuyen hacia el diseño de nanoestructuras funcionales, más allá de su uso tradicional como simples vehículos de fármacos, otorgándoles propiedades -como la auto-replicación- que puedan amplificar su efecto terapéutico.
Currently, the use of nanostructures with therapeutic application for drug delivery and release (e.g. micellar systems) is widespread due to their unique properties that make them indispensable in biomedical and other fields. In this work we describe the systematic study of a series of amphiphilic molecules that form self-replicating micelles, i.e. capable of making copies of themselves. Our system uses two reactive precursors that generate peptide amphiphiles in situ capable of assembling micelles that catalyse their own synthesis, generating identical copies of themselves. The study consisted of combinatorially analysing a collection of precursors of different sizes to finally identify the smallest amphiphile necessary for the formation of self-replicating micelles. These results contribute to the design of functional nanostructures, beyond their traditional use as simple drug vehicles, by giving them properties - such as self-replication - that can amplify their therapeutic effect.
