Abstract
The construction of non-viral gene delivery faces two major challenges: cytotoxicity caused by high cationic charge units and easy degradation by lysosomes. Herein, highly water-dispersible polymeric carbon nitride (PCN) nanosheets were utilized as the core to construct a light-controlled non-cationic gene delivery system with sufficient lysosomal escape ability. In this system, these nanosheets exhibited efficient DNA condensation, outstanding biocompatibility, transfection tracking, light responsiveness and high transfection efficiency. Once PCN-DNA was taken up by the tumor cells, the accumulated ROS generated by photosensitizers (PSs) under light irradiation would destroy the structure of lysosomes, promote the escape of PCN-DNA and increase the efficiency of gene transfection. Simultaneously, the gene transfection process could be tracked in real time through fluorescence imaging technology, which was conducive to investigate the transfection mechanism. In vitro and in vivo experiments further confirmed that PCN nanosheets loaded with the P53 gene were beneficial to the regeneration of the P53 apoptotic pathway, increased tumor sensitivity to PSs, and further induced tumor cell apoptosis. In summary, the highly water-dispersible PCN nanosheets were applied to light-controlled self-escaping gene delivery for the first time, and tumor gene therapy was successfully realized.

Abstract
As a result of the biological activities of natural flavonoids, several synthetic strategies aiming to obtain analogues with improved potency and/or pharmacokinetic profile have been developed. Since the triazole ring has been associated with several biological activities and metabolic stability, hybridization with a 1,2,3-triazole ring has been increasingly reported over the last years. The feasible synthesis through copper (I) catalyzed azide-alkyne cycloaddition (CuAAC) has allowed the accomplishment of several hybrids. Since 2017, almost 700 flavonoid hybrids conjugated with 1,2,3-triazole, including chalcones, flavones, flavanones and flavonols, among others, with antitumor, antimicrobial, antidiabetic, neuroprotective, anti-inflammatory, antioxidant, and antifouling activity have been reported. This review compiles the biological activities recently described for these hybrids, highlighting the mechanism of action and structure-activity relationship (SAR) studies.

Abstract
Although a plethora of gene carriers have been developed for potential gene therapy, imageable stimuli-responsive gene vectors with fast access to the nucleus, high biocompatibility, and transfection efficiency are still scarce. Herein, we report the design and synthesis of four dendrite-shaped cationic liposomes, MPA-HBI-R/DOPE (R: n-butyl, 1; n-octyl, 2; n-dodecyl, 3; palmyl, 4), prepared via esterification of 4-alkoxybenzylideneimidazolinone containing aliphatic chains of different lengths (HBI-R), the green fluorescent protein (GFP) chromophore, with a di[12]aneN3 unit. Liposomes were fabricated via the self-assembly of MPA-HBI-R, assisted with 1,2-dioleoyl-sn-glycerol-3-phosphorylethanolamine (DOPE). These liposomes (MPA-HBI-R/DOPE) exhibited efficient DNA condensation, pH-responsive degradation, excellent cellular biocompatibility (up to 150 μM), and high transfection efficiency. Molecular docking experiments were also used to verify the optimal interaction between MPA-HBI-R and DNA, as well as the fluorescence enhancements. In particular, MPA-HBI-2/DOPE delivered DNA into the nucleus in less than an hour, and its luciferase transfection activity was more than 10 times that by Lipo2000, across multiple cell lines. The GFP chromophore conjugation allowed trackable intracellular delivery and release of DNA in real time via fluorescence imaging. Furthermore, efficient red fluorescent protein (RFP) transfection in zebrafish, with an efficiency of more than 6 times that by Lipo2000, was also achieved. The results not only realized, for the first time, the combination of gene delivery and GFP-simulated light emission, allowing fluorescent tracking and highly efficient gene transfection, but also offered valuable insights into the use of biomimetic chromophore for the development of the next-generation nonviral vectors.

Abstract
A series of multifunctional compounds (MFCs) 1a-1e based on 1,8-naphthalimide and [12]aneN3 building blocks were designed and synthesized. They were used as not only fluorescent probes for recognition of Cu2+ ions but also as non-viral gene vectors for DNA and RNA delivery. Furthermore, their complexes with Cu2+ (1-Cu) could also selectively stain lysosome in HeLa cells. In order to achieve high performance multifunctional materials, structure-performance relationship of MFCs 1a-1e was studied. It was found that MFCs 1a-1e exhibited highly selective fluorescence turn-off for Cu2+, without interference by other metal ions in aqueous solution. The fluorescence emission of 1a-1e was quenched by a factor of 10-fold, 47-fold, 6-fold, 64-fold, and 15-fold respectively in the presence of Cu2+ ions. Due to high sensitivity, good water solubility, and low cytotoxicity, MFCs 1a-1d were successfully applied in the recognition of Cu2+ and selectively staining lysosome in HeLa cells. Most importantly, MFCs 1a and 1b had excellent HeLa cell selectivity in RNA delivery, and their performances were far better than lipofectamine 2000 and 25 kDa PEI.

Abstract
Although a plethora of nonviral gene vectors have been developed for potential gene therapy, imageable gemini surfactants with stimuli-responsiveness and high transfection efficiency are still scarce for gene delivery. Herein, three gemini amphiphiles (DEDPP-4/8/12) consisting of an aggregation-induced emission (AIE) central fluorophore: 5,6-diphenylpyrazine-2,3-diester (DEDPP), decorated with triazole-[12]aneN3 as the hydrophilic moiety and alkyl chains of various lengths as the hydrophobic moiety, were designed and synthesized for trackable gene delivery via optical imaging. All three amphiphiles exhibited ultralow critical micelle concentrations (CMCs) (up to 3.40 × 10-6 M), prominent two-photon absorption properties, and solvatochromic fluorescence. Gel electrophoresis assays demonstrated that the migration of plasmid DNA was completely retarded after condensation with these gemini amphiphiles at low concentrations (up to 10 μM). In addition, the ester bond in these amphiphiles may facilitate vector degradation and DNA release, in response to esterase and the acidic environment inside cells. Upon self-assembly with DOPE to form liposomes, DEDPP-8/DOPE achieved the best transfection efficiency in four cell lines, and the transfection efficiency of DEDPP-8/DOPE in HeLa cell lines was 23.5-fold higher than that of Lipo2000, which is unusually high for small organic molecule-based nonviral vectors. Furthermore, excellent transfection efficiency of DEDPP-8/DOPE was obtained in the presence of serum, and the red fluorescence protein (RFP) gene was successfully transfected in zebrafish embryos. Both one- and two-photon fluorescence imaging clearly demonstrated the delivery process of plasmid DNA. This study demonstrated that gemini-type amphiphiles composed of a two-photon fluorophore core conjugated with triazole-[12]aneN3 via an ester bond afforded an unprecedentedly high transfection efficiency with excellent biocompatibility, which may provide new insights for the design and development of multifunctional nonviral gene vectors for imageable gene delivery.

Abstract
Oligoamide molecular strands with hydrogen-bonding sequences DADDAD and guanidine (O-1) or 1,5,9-triazacyclododecane ([12]aneN3 ; O-2) side chains and oligoamides with hydrogen-bonding sequences ADAADA and octyl moieties (O-3), were synthesized. Two duplexes (D-1 and D-2) were prepared by conjugating the hydrophilic O-1 or O-2 and hydrophobic O-3 through sequence-specific hydrogen-bond association and cross-linked disulfide bonds. Electrophoresis measurements indicated that O-1, O-2, D-1, and D-2 were able to completely retard the DNA mobiliy at concentrations of 30, 30, 10, and 20 μM, respectively. Reversible DNA release in O-1 and O-2 complexes can be achieved in the presence of heparin sodium, whereas the presence of GSH greatly improved DNA release in D-1 and D-2 complexes. The particles formed were in a size range of 50-170 nm with positively charged surfaces. D-1 and D-2 transfected pEGFP-N1 into HeLa cells successfully.

Abstract
Four gemini amphiphiles decorated with triazole-[12]aneN3 as the hydrophilic moiety and various long hydrocarbons as hydrophobic moieties, 1-4, were designed to form micelles possessing the aggregation-induced emission (AIE) property for gene delivery and tracing. All four amphiphiles give ultralow critical micelle concentrations, are pH-/photostable and biocompatible, and completely retard the migration of plasmid DNAs at low concentrations. The DNA-binding abilities of the micelles were fully assessed. The coaggregated nanoparticles of 1-4 with DNAs could convert back into AIE micelles. In vitro transfections indicated that lipids 1 and 2 and their originated liposomes bearing decent delivering abilities have great potentials as nonviral vectors. Finally, on the basis of the transfection and the transitions between condensates and micelles, lipid 2 was singled out as the first example for real-time tracing of the intracellular deliveries of nonlabeled DNA, which provides spatiotemporal messages about the processes of condensate uptake and DNA release.

Abstract
Four [12]aneN3 modified tetraphenylethene (TPE) compounds with different numbers of polyamine units and structure configurations, namely 1, 2, 3, and 4, were designed and synthesized. All compounds showed strong aggregation-induced emission (AIE) features. Compounds 2 and 4 showed significant emission enhancement after the addition of ssDNAs and dsDNAs of different lengths as well as calf thymus DNA (ctDNA). Compounds 1 and 3 showed very poor fluorescent responses toward DNAs. Gel electrophoresis demonstrated the abilities of 1-4 to condense DNA effectively. Complete retardation of plasmid DNA can be achieved at a concentration of 25 μM (1), 8 μM (for 2 and 3) and 4 μM (4). Experiments including fluorescent contrastive titrations, scanning electron microscopy, dynamic laser scattering, EB displacement, and gel electrophoresis demonstrated that the four compounds were able to integrate with DNA through electrostatic interactions and supramolecular stacking. A vicinal configuration around TPE (2) and more triazole-[12]aneN3 recognition sites (4) evidently enhanced the sensing capability toward oligonucleotides, and the TPE unit played an important role in the plasmid DNA condensation process because of its strong binding. With the advantages of low cytotoxicity, effective DNA sensing, and DNA condensing properties, compound 4 was successfully applied as a nonviral DNA vector and fluorescent tracer for label-free gene delivery, which is the first example of a nonviral gene vector with AIE activity.

1,8-naphthalimide modified [12]aneN₃ compounds as selective and sensitive probes for Cu²⁺ ions and ATP in aqueous solution and living cells. Talanta 2016; 152:438-46. [PMID: 26992540 DOI: 10.1016/j.talanta.2016.02.040] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2015] [Revised: 02/12/2016] [Accepted: 02/17/2016] [Indexed: 01/13/2023]
Abstract
A new fluorescent probe 1 featuring one 1,8-naphthalimide and two [12]aneN3 units was synthesized. In the presence of Cu(2+) ions, the fluorescence emission of 1 was quenched by a factor of 127-fold and no interference by other metal ions was observed under physiological conditions. By means of titration and a Job's plot it was established that 1 forms a complex with Cu(2+) ions in a 1:2 ratio. The fluorescence of the 1-Cu(2+) complex was recovered by the addition of Adenosine-5'-triphosphate (ATP) in aqueous solution. Due to its low cytotoxicity, good water solubility, and high sensitivity, probe 1 was successfully applied in the sequential recognition of Cu(2+) and ATP in aqueous solution and HeLa cells. The highly selective and sensitive ability of 1-Cu(2+) complex to detect ATP even enables its bio-analytical applications in real-time imaging in living cells.
