Abstract
Herein, we isolated five natural alkaloids, iso-corydine (iso-CORY), corydine (CORY), sanguinarine (SAN), chelerythrine (CHE) and magnoflorine (MAG), from traditional medicinal herb Dicranostigma leptopodum (Maxim.) Fedde (whole herb) and elucidated their structures. Then we synthesised G5. NHAc-PBA as targeting dendrimer platform to encapsulate the alkaloids into G5. NHAc-PBA-alkaloid complexes, which demonstrated alkaloid-dependent positive zeta potential and hydrodynamic particle size. G5. NHAc-PBA-alkaloid complexes demonstrated obvious breast cancer MCF-7 cell targeting effect. Among the G5. NHAc-PBA-alkaloid complexes, G5.NHAc-PBA-CHE (IC50=13.66 μM) demonstrated the highest MCF-7 cell inhibition capability and G5.NHAc-PBA-MAG (IC50=24.63 μM) had equivalent inhibitory effects on cell proliferation that comparable to the level of free MAG (IC50=23.74 μM), which made them the potential breast cancer targeting formulation for chemotherapeutic application. This work successfully demonstrated a pharmaceutical research model of 'natural bioactive product isolation-drug formulation preparation-breast cancer cell targeting inhibition'.

Abstract
Bacterial diseases have been considered the most crucial issue and are threatening human health all around the world. Also, resistance to antimicrobial drugs has become a big hurdle against efficient therapy. As a result, recombinant chimeric endolysin was produced in E. coli host to use as a potential antibacterial agent against bacteria resistance and replacement to conventional antibiotics in this study. Then, chitosan (C)-coated nanoscale metal-organic frameworks (CS-NMOFs) nanocomposite was synthesized as a novel nano delivery system to further improve the antibacterial activity of endolysin. After characterization of nanocomposite with analytical devices such as FT-IR, DLS, and TEM and determining the nanometric size of samples (30 nm to 90 nm), endolysin was covalently (endolysin-CS-NMOFs (C)) and non-covalently (endolysin-CS-NMOFs (NC)) conjugated to nanocomposite. Thereafter, the lytic ability, synergistic interaction, and biofilm reduction manner of endolysin-containing CS-NMOF nanocomposites were evaluated on E. coli, S. aureus, and P. aeruginosa strains. The results depicted an excellent lytic ability of nanocomposites after 24 h and 48 h of treatment, especially endolysin-CS-NMOFs (NC) on E. coli and P. aeruginosa strains. The synergistic interaction between nanocomposite and vancomycin did not attain for P. aeruginosa strain whereas the reverse was true for E. coli and S. aureus strains at 8 ng/mL concentration. Next, nanocomposites demonstrated potential biofilm reduction activities in various strains, especially in S. aureus and P. aeruginosa. Ultimately, our outputs demonstrate an efficient performance of the synthesized nanocomposite as an appropriate substitution for conventional antibiotics against bacteria.

Abstract
Dendrimers are a family of polymers with highly branched structure, well-defined composition, and extensive functional groups, which have attracted great attention in biomedical applications. Micelles formed by dendrimers are ideal nanocarriers for delivering anticancer agents due to the explicit study of their characteristics of particle size, charge, and biological properties such as toxicity, blood circulation time, biodistribution, and cellular internalization. Here, the classification, preparation, and structure of dendrimer micelles are reviewed, and the specific functional groups modified on the surface of dendrimers for tumor active targeting, stimuli-responsive drug release, reduced toxicity, and prolonged blood circulation time are discussed. In addition, their applications are summarized as various platforms for biomedical applications related to cancer therapy including drug delivery, gene transfection, nano-contrast for imaging, and combined therapy. Other applications such as tissue engineering and biosensor are also involved. Finally, the possible challenges and perspectives of dendrimer micelles for their further applications are discussed.

Abstract
Abstract Breast cancer due to its high incidence and mortality is the second leading cause of death among females. On the other hand, nanoparticle-based drug delivery is one of the most promising approaches in cancer therapy, nowadays. Hence, margetuximab- and polyethylene glycol-conjugated PAMAM G4 dendrimers were efficiently synthesized for targeted delivery of quercetin (therapeutic agent) to MDA-MB-231 breast cancer cells. Synthesized nano-complexes were characterized using analytical devices such as FT-IR, TGA, DLS, Zeta potential analyzer, and TEM. The size less than 40 nm, - 18.8 mV surface charge, efficient drug loading capacity (21.48%), and controlled drug release (about 45% of drug release normal pH after 8 h) were determined for the nano-complex. In the biomedical test, the cell viability was obtained 14.67% at 24 h of post-treatment for 800 nM concentration, and IC50 was ascertained at 100 nM for the nano-complex. The expression of apoptotic Bax and Caspase9 genes was increased by more than eightfolds and more than fivefolds after treatment with an optimal concentration of nanocarrier. Also, more than threefolds of cell cycle arrest was observed at the optimal concentration synthetics, and 27.5% breast cancer cell apoptosis was detected after treatment with 100 nM nano-complex. These outputs have been indicating the potential capacity of synthesized nano-complex in inhibiting the growth of breast cancer cells. Graphic abstract

Abstract
In recent years, the use of poly(amidoamine) (PAMAM) dendrimers of different generations as building blocks or reactive modules to construct core-shell tecto dendrimers (CSTDs) that are superior to the performance of single-generation dendrimers has received great attention in the field of biomedical applications. The CSTDs are always based on high-generation dendrimers as the core and low-generation dendrimers as the shell; not only do they have excellent properties similar to single high-generation dendrimers, but they also have overcome some of the shortcomings (e.g., limited drug loading capacity or enhanced permeability and retention effect due to small size) of single-generation dendrimers in biomedical applications. Herein, the recent advances of CSTDs synthesized by different approaches as nanoplatforms for different biomedical applications, particularly for chemotherapy, gene delivery, and combination therapy, as well as biological imaging, are summarized. In addition, the current challenges and future perspectives of CSTDs are also discussed.

Abstract
The use of nanomaterials for drug delivery offers many advantages including the targeted delivery of drugs and their controlled release. Nonetheless, entry into the target cells remains a challenge for many nanomaterials used for drug delivery. Moreover, cellular uptake limits the therapeutic efficiency of many anticancer drugs. An important goal is to increase the specific accumulation of these nanoparticles (NPs) at the desired cancerous tissues. Notably, cancer cells show a high demand for some amino acids and we have used this knowledge to develop novel carrier systems. In this study, drug carriers were produced by the conjugation of multiple amino acids such as l-histidine (H) and l-cysteine (C) or single amino acids such as only H with the G4.5 dendrimers (G) to produce GHC aggregates and GH NP carriers, respectively. Doxorubicin was loaded into the G4.5, GH, and GHC dendrimers (G/DOX, GH/DOX and GHC/DOX, respectively) and the release mechanism was demonstrated at pH 7.4 and pH 5.0. GH/DOX and GHC/DOX showed better stability under physiological conditions than the dendrimer alone (G/DOX). GH/DOX and GHC/DOX exhibited higher inhibition of HeLa cell proliferation in in vitro and in vivo studies in zebrafish, confirming the early release of DOX by disrupting the endosomal membrane and triggering the destabilization of carriers at a lower pH of 5.0.

Abstract
Pancreatic β-cell membranes and presynaptic areas of neurons contain analogous protein complexes that control the secretion of bioactive molecules. These complexes include the neuroligins (NLs) and their binding partners, the neurexins (NXs). It has been recently reported that both insulin secretion and the proliferation rates of β-cells increase when cells are co-cultured with full-length NL-2 clusters. The pharmacological use of full-length protein is always problematic due to its unfavorable pharmacokinetic properties. Thus, NL-2-derived short peptide was conjugated to the surface of polyamidoamine-based (PAMAM) dendrimers. This nanoscale composite improved β-cell functions in terms of the rate of proliferation, glucose-stimulated insulin secretion (GSIS), and functional maturation. This functionalized dendrimer also protected β-cells under cellular stress conditions. In addition, various novel peptidomimetic scaffolds of NL-2-derived peptide were designed, synthesized, and conjugated to the surface of PAMAM in order to increase the biostability of the conjugates. However, after being covered by peptidomimetics, PAMAM dendrimers were inactive. Thus, the original peptide-based PAMAM dendrimer is a leading compound for continued research that might provide a unique starting point for designing an innovative class of antidiabetic therapeutics that possess a unique mode of action.

Abstract
There has been growing interest in the research of nanomaterials for biomedical applications in recent decades. Herein, a simple approach to synthesize the G4.5-Gd2O3-poly(ethylene glycol) (G4.5-Gd2O3-PEG) nanoparticles (NPs) that demonstrate potential as dual (T1 and T2) contrasting agents in magnetic resonance imaging (MRI) has been reported in this study. Compared to the clinically popular Gd-DTPA contrasting agents, G4.5-Gd2O3-PEG NPs exhibited a longer longitudinal relaxation time (T1) and better biocompatibility when incubated with macrophage cell line RAW264.7 in vitro. Furthermore, the longitudinal relaxivity (r1) of G4.5-Gd2O3-PEG NPs was 53.9 s-1 mM-1 at 7T, which is equivalent to 4.8 times greater than to the Gd-DTPA contrasting agents. An in vivo T1-weighted MRI results revealed that G4.5-Gd2O3-PEG NPs significantly enhanced signals in the intestines, kidney, liver, bladder, and spleen. In addition, the T2-weighted MRI results revealed darker contrast in the kidney, which proves that G4.5-Gd2O3-PEG NPs can be exploited as T1 and T2 contrasting agents. In summary, these findings suggest that the G4.5-Gd2O3-PEG NPs synthesized by an alternative approach can be used as dual MRI contrasting agents.

Abstract
In this study, PAMAM dendrimer (G4.5) was conjugated with two targeting moieties, IL-6 antibody and RGD peptide (G4.5-IL6 and G4.5-RGD conjugates). Doxorubicin anticancer drug was physically loaded onto G4.5-IL6 and G4.5-RGD with the encapsulation efficiency of 51.3 and 30.1% respectively. The cellular internalization and uptake efficiency of G4.5-IL6/DOX and G4.5-RGD/DOX complexes was observed and compared by confocal microscopy and flow cytometry using HeLa cells, respectively. The lower IC50 value of G4.5-IL6/DOX in comparison to G4.5-RGD/DOX is indication that higher drug loading and faster drug release rate corresponded with greater cytotoxicity. The cytotoxic effect was further verified by increment in late apoptotic/necrotic cells due to delivery of drug through receptor-mediated endocytosis. On the basis of these results, G4.5-IL6 is a better suited carrier for targeted drug delivery of DOX to cervical cancer cells.
