Abstract
Aptamers are single-stranded DNA or RNA with 20-100 nucleotides in length that can specifically bind to target molecules via formed three-dimensional structures. These innovative targeting molecules have attracted an increasing interest in the biomedical field. Compared to traditional protein antibodies, aptamers have several advantages, such as small size, high binding affinity, specificity, good biocompatibility, high stability and low immunogenicity, which all contribute to their wide application in the biomedical field. Aptamers can bind to the receptors on the cell membrane and mediate themselves or conjugated nanoparticles to enter into cells. Therefore, aptamers can be served as ideal targeting ligands for drug delivery. Since their excellent properties, different aptamer-mediated drug delivery systems had been developed for cancer therapy. This review provides a brief overview of recent advances in drug delivery systems based on aptamers. The advantages, challenges and future prospectives are also discussed.

[PMID: 30966226 PMCID: PMC6415174 DOI: 10.3390/polym10020190] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Revised: 01/30/2018] [Accepted: 02/05/2018] [Indexed: 11/16/2022] Open
Abstract
As a drug carrier, polyrotaxane (PR) has been used for targeted delivery and sustained release of drugs, whereas silver sulfadiazine (SD-Ag) is an emerging antibiotic agent. PR was synthesized by the use of α-cyclodextrin (CD) and poly(ethylene glycol) (PEG), and a specific antibacterial material (PR-(SD-Ag)) was then prepared by loading SD-Ag onto PR with different mass ratios. The loading capacity and the encapsulation efficiency were 90% at a mass ratio of 1:1 of PR and SD-Ag. SD-Ag was released stably and slowly within 6 d in vitro, and its cumulative release reached more than 85%. The mechanism of PR loading SD-Ag might be that SD-Ag attached to the edge of α-CD through hydrogen bonding. PR-(SD-Ag) showed a higher light stability than SD-Ag and held excellent antibacterial properties against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus).

Chemistry 2017; 23:4708-4712. [PMID: 28185437 DOI: 10.1002/chem.201700206] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2017] [Indexed: 12/22/2022]
Abstract
Synthetic receptors selective for target peptides or proteins have received attention because of their potential applications in the separation of biomolecules and biomedical diagnostics. Herein, a [2]rotaxane-based functional monomer containing monocarboxylated α-cyclodextrin (α-CD) was synthesized, and its crosslinked polymers were evaluated to determine their binding ability to a model peptide, angiotensin III (Arg-Val-Tyr-Ile-His-Pro-Phe), containing an arginine (Arg) residue. The binding ability of the resulting polymers toward angiotensin III, angiotensin IV (Val-Tyr-Ile-His-Pro-Phe), and FMRF-amide (Phe-Met-Arg-Phe) was examined by the batch-binding assay and compared with that of control polymers, in which maleic acid-introduced α-CD was chemically crosslinked. The results suggest that the [2]rotaxane-based functional monomer in the crosslinked polymer contributes to the high affinity toward angiotensin III. The α-CD motion and rotation within the [2]rotaxane-based crosslinked polymer may be applicable for designing molecular recognition materials.

Abstract
A polyrotaxane-based nanoconstruct with pliable structure carrying a chemotherapeutic drug was developed for targeting circulating lymphoblastic leukaemia cells in a fluidic environment of blood vessels in vivo. By introducing lymphoblast targeting aptamer DNA through cyclodextrin, threaded in poly(ethylene glycol) as polyrotaxane, target aptamer slides along the long polymeric chain and actively search for target ligand, leading to active targeting in dynamic fluidic system which is enhanced by up to 6–fold compared with that of control carriers with non–sliding targeting ligands. Moreover, the drug carrier was made stimuli-responsive by employing i-motif DNA to selective releases of its payload at intracellular acidic condition. These combined features resulted in the effective remission of lymphoblastic leukaemia both in vitro and in dynamic blood vessels in vivo.
