Applications of Dendrimers in Drug Delivery Agents, Diagnosis, Therapy, and Detection

Abstract: In recent years, the application of dendrimers in biomedicine attracted much attention from scientists. Dendrimers are interesting for biomedical applications because of their characteristics, including: a hyperbranching, well-defined globular structures, excellent structural uniformity, multivalency, variable chemical composition, and high biological compatibility. In particular, the three-dimensional architecture of dendrimers can incorporate a variety of biologically active agents to form biologically activ… Show more

“…There exist a large number of scientific reports regarding the therapeutic potential of dendrimers and especially polyamidoamino (PAMAM) dendrimers 912 . Also the dendrimers themselves are reported to possess therapeutic properties, but more often the PAMAM dendrimer has a therapeutic drug attached to the terminal group(s) 13 .…”

“…For example, drug‐delivery research using PAMAM dendrimers presents an opportunity for improvement. Traditionally, drugs are either covalently bound to the terminal groups of the dendrimer's branches or noncovalently entrapped within the internal cavities of the PAMAM architecture . Both approaches present disadvantages.…”

“…Absorption in a biocompatible and hydrophilic dendrimer seemingly solves all of these problems. When using this approach, however, undesired drug leakage is inevitable . Since the therapeutic is only trapped by noncovalent interactions, its release in the systemic circulation and off‐target effects are difficult to prevent.…”

“…Eles são formados por uma unidade estrutural central multifuncional "C"; unidades estruturais de ramificação dendríticas "D"; e unidades estruturais terminais "T" (nas quais apenas um de seus grupos funcionais se encontra ligado a estrutura do polímero), apontadas na Figura 1-11; adquirindo uma estrutura globular. (NORIEGA-LUNA et al, 2014;QIAO, 2007 Os polímeros apresentados previamente podem ter a sua estrutura organizada no formato "core-shell", Figura 1-13. Este tipo de formato consiste em um núcleo central, o "core", cujo ambiente químico determina as propriedades de solubilização de moléculas no interior da estrutura; e o "shell", que consiste na camada de grupos ou cadeias externos acoplados ao polímero e determina a solubilidade, afinidade e comportamento físico e químico da estrutura em diferentes solventes.…”

(NORIEGA-LUNA et al, 2014;QIAO, 2007). O tamanho dos dendrímeros pode ser reportado pelo seu número de gerações, ou seja o número de substituições completas das unidades terminais por monômeros, formando uma nova "camada" de unidades terminais.…”
