Dendrimerler, bir çekirdek, çekirdek etrafındaki dallanma birimleri ve fonksiyonel grup olarak da adlandırılan yüzey gruplarından oluşan polimerik ilaç taşıyıcı sistemlerdir. Dendrimerlerin çeşitliliği fonksiyonel gruplarla sağlanmaktadır. Dallanma birimleri ise, dendrimerlerin tekrarlı şekilde büyümesini sağlamaktadır. Dendrimerlerin iç kısmında bulunan boşluğa etkin maddenin enkapsülasyonu mümkündür. Bu sayede, etkin maddenin kontrollü salımı sağlanabilir. Bununla birlikte, çok dallanmış yapıda bulunması ve yüzeyinde bulunan birçok fonksiyonel grup, etkin maddelerin ve çeşitli moleküllerin aynı anda konjugasyon ile dendrimere eklenmesini sağlar. Böylece etkin maddelerin spesifik bir bölgeye hedeflendirilmesi sağlanabilir, etkin maddelerin çözünürlüğü, biyoyararlanımı artırılabilir. Bu derlemede, dendrimerlerin özellikleri ve uygulama alanları değerlendirilmiştir.

Dendrimers-drug delivery systems

Öz

Dendrimers consisting a core, branching units around the core and surface groups also named as functional group are new polymeric drug delivery systems. The variety of dendrimers are provided with functional groups. Branching units of the dendrimer provide its growth iteratively. The space in the interior of the dendrimers allows encapsulation of the active ingredient possible. In this way, the controlled release of the active ingredient can be achieved. However, being in a very branched structure and having many functional groups on the surface provide the addition of variety of molecules and active ingredient by conjugation simultaneously. Thus, targeting of active ingredients to a specific site of the body can be achieved as well as the solubility and bioavailability of the active ingredients can be increased. In this paper, the properties of dendrimers and application areas were evaluated.
