Background: Nanoscale poly (amidoamine) dendrimers have been investigated for their biological demands, but their antibacterial activity has not been widely discovered. Thus, the sixth generation of poly (amidoamine) dendrimer (PAMAM-G6) was synthesized and its antibacterial activities were evaluated on Gram-negative bacteria; P. aeruginosa, E. coli, A. baumannii, S. typhimurium, S. dysenteriae...

Rheumatoid arthritis is a chronic autoimmune disease characterised by joint synovial inflammation, along with cartilage and bone tissue destruction. Dendrimers can offer new opportunities as drug delivery systems of molecules interest. Herein we aimed to develop poly(amidoamine) dendrimers (PAMAM), functionalised chondroitin sulphate (CS), lined anti-TNF α antibodies (Abs) provide anti-inflamma...

BACKGROUND Bioconjugates of a polyamidoamine (PAMAM) G3 dendrimer and an aldehyde were synthesized as carriers for vitamins A and B₆, and the bioavailability of these vitamins for skin nutrition was investigated. METHODS Nuclear magnetic resonance (NMR) and ultraviolet-visible methods were used to characterize the structure of the bioconjugates and for monitoring release of pyridoxal (Pyr) an...

Highly stable dendrimer-encapsulated Pd nanoparticles in ionic liquids were prepared for the first time by using charged PAMAM dendrimers as templates, which could maintain hydrogenation efficiency for up to at least 12 recycles.

A marked increase of relaxivity has been observed upon rigidifying the internal frame of Gd-containing PAMAM dendrimers: the effect has been attained by either protonation of the dendrimer or by forming supramolecular adducts with cationic polyaminoacids.

The effective life-time of new antimicrobials until the appearance first resistant strains is steadily decreasing, which discourages incentives for commercialization required clinical translation and application. Therefore, development should not only focus on better killing antimicrobial-resistant strains, but as a paradigm shift developing that prevent induction resistance. Heterofunctionaliz...

Gene, short hairpin RNA (shRNA) and small interfering RNA (siRNA) delivery can be particularly used for the treatment of diseases by the entry of genetic materials mammalian cells either to express new proteins or to suppress the expression of proteins, respectively. Polyamidoamine (PAMAM) StarburstTM dendrimers are used as non-viral vectors (carriers) for gene, shRNA and siRNA delivery. Recent...
