Abstract: Drug delivery systems are designed for the targeted delivery and controlled release
of medicinal agents. Among the materials employed as drug delivery systems, dendrimers
have gained increasing interest in recent years because of their properties and
structural characteristics. The use of dendrimer-nanocarrier formulations enhances the
safety and bioavailability, increases the solubility in water, improves stability and pharmacokinetic
profile, and enables efficient delivery of the target drug to a specific site.
However, the synthesis of dendritic architectures through convergent or divergent methods
has drawbacks and limitations that disrupt aspects related to design and construction,
and consequently, slow down the transfer from academia to industry. In that sense, the
implementation of click chemistry has received increasing attention in the last years, as it
offers new efficient approaches to obtain dendritic species in good yields and higher
monodispersity. This review focuses on recent strategies for building dendrimer drug delivery
systems using click reactions from 2015 to early 2021. The dendritic structures
showed in this review are based on β -cyclodextrins (β-CD), poly(amidoamine) (PAMAM),
dendritic poly (lysine) (PLLD), dimethylolpropionic acid (bis-MPA), phosphoramidate
(PAD), and poly(propargyl alcohol-4-mercaptobutyric (PPMA).
