Abstract
One of the major limitations for the treatment of many diseases is an inability of drugs to cross the cell membrane barrier. Different kinds of carriers are being investigated to improve drug bioavailability. Among them, lipid or polymer-based systems are of special interest due to their biocompatibility. In our study, we combined dendritic and liposomal carriers and analysed the biochemical and biophysical properties of these formulations. Two preparation methods of Liposomal Locked-in Dendrimers (LLDs) systems have been established and compared. Carbosilane ruthenium metallodendrimer was complexed with an anti-cancer drug (doxorubicin) and locked in a liposomal structure, using both techniques. The LLDs systems formed by hydrophilic locking had more efficient transfection profiles and interacted with the erythrocyte membrane better than systems using the hydrophobic method. The results indicate these systems have improved transfection properties when compared to non-complexed components. The coating of dendrimers with lipids significantly reduced their hemotoxicity and cytotoxicity. The nanometric size, low polydispersity index and reduced positive zeta potential of such complexes made them attractive for future application in drug delivery. The formulations prepared by the hydrophobic locking protocol were not effective and will not be considered furthermore as prospective drug delivery systems. In contrast, the formulations formed by the hydrophilic loading method have shown promising results where the cytotoxicity of LLD systems with doxorubicin was more effective against cancer than normal cells.

Carbosilane ruthenium metallodendrimer as alternative anti-cancer drug carrier in triple negative breast cancer mouse model: A preliminary study. Int J Pharm 2023; 636:122784.

Abstract
The carbosilane metallodendrimer G1-[[NCPh(o-N)Ru(η6- p-cymene)Cl]Cl]4 (CRD13), based on an arene Ru(II) complex coordinated to imino-pyridine surface groups, has been conjugated with anti-cancer drugs. Ruthenium in the positively-charged dendrimer structure allows this nanoparticle to be considered as an anticancer drug carrier, made more efficient because ruthenium has anticancer properties. The ability of CRD13 to form complexes with Doxorubicin (DOX), 5-Fluorouracil (5-Fu), and Methotrexate (MTX) has been evaluated using zeta potential measurement, transmission electron microscopy (TEM) and computer simulation. The results show that it forms stable nanocomplexes with all those drugs, enhancing their effectiveness against MDA-MB-231 cancer cells. In vivo tests indicate that the CRD13/DOX system caused a decrease of tumor weight in mice with triple negative breast cancer. However, the tumors were most visibly reduced when naked dendrimers were injected.

Dendrimeric HIV-peptide delivery nanosystem affects lipid membranes structure. Sci Rep 2021; 11:16810.

Abstract
The aim of this study was to evaluate the nature and mechanisms of interaction between HIV peptide/dendrimer complexes (dendriplex) and artificial lipid membranes, such as large unilayered vesicles (LUV) and lipid monolayers in the air-water interface. Dendriplexes were combined as one of three HIV-derived peptides (Gp160, P24 and Nef) and one of two cationic phosphorus dendrimers (CPD-G3 and CPD-G4). LUVs were formed of 1,2-dimyristoyl-sn-glycero-3-phosphatidylcholine (DMPC) or of a mixture of DMPC and dipalmitoyl-phosphatidylglycerol (DPPG). Interactions between dendriplexes and vesicles were characterized by dynamic light scattering (DLS), fluorescence anisotropy, differential scanning calorimetry (DSC) and Langmuir-Blodgett methods. The morphology of formed systems was examined by transmission electron microscopy (TEM). The results suggest that dendriplexes interact with both hydrophobic and hydrophilic regions of lipid bilayers. The interactions between dendriplexes and negatively charged lipids (DMPC-DPPG) were stronger than those between dendriplexes and liposomes composed of zwitterionic lipids (DMPC). The former were primarily of electrostatic nature due to the positive charge of dendriplexes and the negative charge of the membrane, whereas the latter can be attributed to disturbances in the hydrophobic domain of the membrane. Obtained results provide new information about mechanisms of interaction between lipid membranes and nanocomplexes formed with HIV-derived peptides and phosphorus dendrimers. These data could be important for the choosing the appropriate antigen delivery vehicle in the new vaccines against HIV infection.

Abstract
The unavailability of effective and safe human immunodeficiency virus (HIV) vaccines incites several approaches for development of the efficient antigen/adjuvant vaccination composite. In this study, three different dendronized gold nanoparticles (AuNPs 13-15) were investigated for a complexation ability with gp160 synthetic peptides derived from an HIV envelope. It has been shown that HIV peptides interacted with nanoparticles as evident from the changes in their secondary structures, restricted the mobility of the attached fluorescence dye, and enhanced peptide helicity confirmed by the fluorescence polarization and circular dichroism results. Transmission electron microscopy visualized complexes as cloud-like structures with attached nanoparticles. AuNP 13-15 nanoparticles bind negatively charged peptides depending on the number of functional groups; the fastest saturation and peptide retardation were observed for the most dendronized nanoparticle as indicated from dynamic light scattering, laser Doppler velocimetry, and agarose gel electrophoresis experiments. Dendronized gold nanoparticles can be considered one of the potential HIV peptide-based vaccination platforms.

Abstract
Anionic carbosilane dendrimers such as G2-S16 are very effective in preventing HSV-2 infection both in vitro and in vivo. We present the main achievements obtained for the G2-S16 dendrimer in vivo, especially related to its efficacy against HSV-2 infection. Moreover, we discuss the mechanisms by which the G2-S16 dendrimer applied vaginally as a topical microbicide has been demonstrated to be safe and harmless for the vaginal microbiome balance, as both conditions present an essential step that has to be overcome during microbicide development. This review points to the marked protective effect of the G2-S16 dendrimer against sexually transmitted HSV-2 infection, supporting its role as a possible microbicide against HSV-2 infection.

Abstract
Cationic dendrimers are considered one of the best drug transporters in the body. However, in order to improve their biocompatibility, modification of them is required to reduce toxicity. In this way, many dendrimers may lose their original properties, for example, anticancer. To improve biocompatibility of dendrimers, it is possible to complex them with albumin, as is done very often in drug delivery. However, the interaction of dendrimers with albumin can lead to protein structure disruption or no complexation at all. Therefore, the investigation of the interaction between cationic poly-(propylene imine) dendrimers and polyethylene glycol (PEG)-albumin by fluorescence, circular dichroism, small angle X-ray scattering (SAXS), and transmission electron microscopy was carried out. Results show that cationic dendrimers bind to PEGylated albumin at PEG and albumin surfaces. The obtained results for 5k-PEG indicate a preferential binding of the dendrimers to PEG. For 20k-PEG binding of dendrimers to PEG and protein could induce a collapse of the PEG chain onto the protein surface. This opens up new possibilities to the use of PEGylated albumin as a platform to carry dendrimers without changing the albumin structure and improve the pharmacokinetic properties of dendrimers without further modification.

Abstract
Metallodendrimers-dendrimers with included metals-are widely investigated as biocompatible equivalents to metal nanoparticles. Applications can be expected in the fields of catalysis, as chemical sensors in molecular recognition and as anticancer drugs. Metallodendrimers can also mimic certain biomolecules, for example, haemoprotein in the case of using a dendrimer with a porphyrin core. In previous papers, we showed the promising anticancer effects of carbosilane ruthenium dendrimers. The present paper is devoted to studying biocompatibility and the cytotoxic effect on normal and cancer cells of carbosilane ruthenium dendrimers labelled with fluorescent probe fluorescein isothiocyanate (FITC). The addition of fluorescent probe allowed tracking the metallodendrimer in both normal and cancer cells. It was found that carbosilane ruthenium dendrimer labelled with FITC in concentration up to 10 µmol/L was more cytotoxic for cancer cells than for normal cells. Thus, FITC labelled carbosilane ruthenium dendrimer is a good candidate for diagnostic imaging and studying anticancer effects of metallodendrimers in cancer therapy.

Abstract
An in-depth analysis of nanotechnology applications for the improvement of solubility, distribution, bioavailability and stability of reverse transcriptase inhibitors is reported. Current clinically used nucleoside and non-nucleoside agents, included in combination therapies, were examined in the present survey, as drugs belonging to these classes are the major component of highly active antiretroviral treatments. The inclusion of such agents into supramolecular vesicular systems, such as liposomes, niosomes and lipid solid NPs, overcomes several drawbacks related to the action of these drugs, including drug instability and unfavorable pharmacokinetics. Overall results reported in the literature show that the performances of these drugs could be significantly improved by inclusion into nanosystems.

Knauer N, Pashkina E, Apartsin E. Topological Aspects of the Design of Nanocarriers for Therapeutic Peptides and Proteins. Pharmaceutics 2019; 11:E91.

Abstract
Supramolecular chemistry holds great potential for the design of versatile and safe carriers for therapeutic proteins and peptides. Nanocarriers can be designed to meet specific criteria for given application (exact drug, administration route, target tissue, etc.). However, alterations in the topology of formulation components can drastically change their activity. This is why the supramolecular topology of therapeutic nanoconstructions has to be considered. Herein, we discuss several topological groups used for the design of nanoformulations for peptide and protein delivery: modification of polypeptide chains by host-guest interactions; packaging of proteins and peptides into liposomes; complexation and conjugation with dendrimers. Each topological type has its own advantages and disadvantages, so careful design of nanoformulations is needed. Ideally, each case where nanomedicine is needed requires a therapeutic construction specially created for that taking into account features of the administration route, target tissue, or organ, properties of a drug, its bioavailability, etc. The wide number of studies in the field of protein delivery by supramolecular and nanocarriers for proteins and peptides evidence their increasing potential for different aspects of the innovative medicine. Although significant progress has been achieved in the field, there are several remaining challenges to be overcome in future.

Anticancer Activity of Dendriplexes against Advanced Prostate Cancer from Protumoral Peptides and Cationic Carbosilane Dendrimers. Biomacromolecules 2019; 20:1224-1234.

Abstract
The interaction of neuropeptides, vasoactive intestinal peptide (VIP), or growth hormone-releasing hormone (GHRH), with a cationic carbosilane dendrimer forms dendriplexes with antitumoral behavior in advanced prostate cancer cells PC3. At the concentrations used for dendriplexes formation, the free peptides were protumoral and prometastatic in advanced prostate cancer, while dendrimer only showed low cytotoxicity, but did not avoid the metastatic behavior of PC3 cells. However, these nanoplexes favored also cell adhesion and avoided cell migration. Also, the dendriplexes were not toxic for no tumoral prostate cells (RPWE-1) or fibroblasts. The use of labeled GHRH peptide (rhodamine labeled) and a dendrimer (fluorescein labeled) allowed us to observe that both systems reach the intracellular milieu after dendriplex formation. The treatment of PC3 cells with the nanoplexes reduced expression of vascular endothelial growth factor (VEGF) and cyclic adenosine monophosphate (cAMP). Molecular modeling analysis highlights the important contribution of the carbosilane framework in the stabilization of the dendriplex, since dendrimer interacts with a peptide region where hydrophobic amino acids are presented.

Abstract
Dendrimers are drug delivery systems that are characterized by a three-dimensional, star-shaped, branched macromolecular network. They possess ideal properties such as low polydispersity index, biocompatibility and good water solubility. They are made up of the interior and the exterior layers. The exterior layer consists of functional groups that are useful for conjugation of drugs and targeting moieties. The interior layer exhibits improved drug encapsulation efficiency, reduced drug toxicity, and controlled release mechanisms. These unique properties make them useful for drug delivery. Dendrimers have attracted considerable attention as drug delivery system for the treatment of infectious diseases. The treatment of infectious diseases is hampered severely by drug resistance. Several properties of dendrimers such as their ability to overcome drug resistance, toxicity and control the release mechanism of the encapsulated drugs make them ideal systems for the treatment of infectious disease. The aim of this review is to discuss the potentials of dendrimers for the treatment of viral and parasitic infections.

Abstract
Over the years, the scientific importance of nanoparticles for biomedical applications has increased. The high stability and biocompatibility, together with the low toxicity of the nanoparticles developed lead to their use as targeted drug delivery systems, bioimaging systems, and biosensors. The wide range of nanoparticles size, from 10 nm to 1 μm, as well as their optical properties, allow them to be studied using microscopy and spectroscopy techniques. In order to be effectively used, the physicochemical properties of nanoparticle formulations need to be taken into account, namely, particle size, surface charge distribution, surface derivatization and/or loading capacity, and related interactions. These properties need to be optimized considering the final nanoparticle intended biodistribution and target. In this review, we cover light scattering based techniques, namely dynamic light scattering and zeta-potential, used for the physicochemical characterization of nanoparticles. Dynamic light scattering is used to measure nanoparticles size, but also to evaluate their stability over time in suspension, at different pH and temperature conditions. Zeta-potential is used to characterize nanoparticles surface charge, obtaining information about their stability and surface interaction with other molecules. In this review, we focus on nanoparticle characterization and application in infection, cancer and cardiovascular diseases.

Abstract
Dendrimers, which are considered as one of the most promising tools in the field of nanobiotechnology due to their structural organization, showed a great potential in gene therapy, drug delivery, medical imaging and as antimicrobial and antiviral agents. This article is devoted to study interactions between new carbosilane-based metallodendrimers containing ruthenium and anti-cancer small interfering RNA (siRNA). Formation of complexes between anti-cancer siRNAs and Ru-based carbosilane dendrimers was evaluated by transmission electron microscopy, circular dichroism and fluorescence. The zeta-potential and the size of dendriplexes were determined by dynamic light scattering. The internalization of dendriplexes were estimated using HL-60 cells. Results show that ruthenium dendrimers associated with anticancer siRNA have the ability to deliver siRNA as non-viral vectors into the cancer cells. Moreover, dendrimers can protect siRNA against nuclease degradation. Nevertheless, further research need to be performed to examine the therapeutic potential of ruthenium dendrimers as well as dendrimers complexed with siRNA and anticancer drugs towards cancer cells.

Abstract
Although the antiretroviral therapy has led to a long-term control of HIV-1, it does not cure the disease. Therefore, several strategies are being explored to develop an effective HIV vaccine, such as the use of dendritic cells (DCs). DC-based immunotherapies bear different limitations, but one of the most critical point is the antigen loading into DCs. Nanotechnology offers new tools to overcome these constraints. Dendrimers have been proposed as carriers for targeted delivery of HIV antigens in DCs. These nanosystems can release the antigens in a controlled manner leading to a more potent specific immune response. This review focuses on the first steps for clinical development of dendrimers to assess their safety and potential use in DC-based immunotherapies against HIV.

Abstract
This paper examines a perspective on the use of newly engineered nanomaterials as effective and safe carriers of genes for the therapy of cancer. Three different groups of cationic dendrimers (PAMAM, phosphorus and carbosilane) were complexed with anticancer siRNA and their biophysical properties of the dendriplexes analyzed. The potential of the dendrimers as nanocarriers for anticancer siBcl-xl, siBcl-2, siMcl-1 siRNAs and a siScrambled sequence was explored. Dendrimer/siRNA complexes were characterized by methods including fluorescence, zeta potential, dynamic light scattering, circular dichroism, gel electrophoresis and transmission electron microscopy. Some of the experiments were done with heparin to check if siRNA can be easily disassociated from the complexes, and whether released siRNA maintains its structure after interaction with the dendrimer. The results indicate that siRNAs form complexes with all the dendrimers tested. Oligoribonucleotide duplexes can be released from dendriplexes after heparin treatment and the structure of siRNA is maintained in the case of PAMAM or carbosilane dendrimers. The dendrimers were also effective in protecting siRNA from RNase A activity. The selection of the best siRNA carrier will be made based on cell culture studies (Part B).

Abstract
This study investigates the role of carbosilane dendrimers in fibrillation of α-synuclein and prevention of the mouse hippocampal cell (mHippoE-18) from rotenone-induced damage. Examining the interaction between carbosilane dendrimers and α-synuclein, we found that the dendrimers inhibit fibril formation. We also investigated cell viability, the production of reactive oxygen species (ROS), and mitochondrial membrane potential. mHippoE-18 cells were preincubated with carbosilane dendrimers before rotenone was added. All the dendrimers possess potential protection activity. Preincubation with dendrimers contributed to: increased viability, higher mitochondrial membrane potential, and reduced ROS level in cells. The probable mechanism of cell protection lies in the ability of dendrimers to capture rotenone by encapsulating or binding to its surface groups. The fact that dendrimers have prevention potential is important in the search for new pharmacological strategies against neurodegenerative disorders.

Abstract
AIMS We have investigated the effect of surface charge of model lipid membranes on their interactions with dendriplexes formed by HIV-derived peptides and 2 types of positively charged carbosilane dendrimers (CBD). METHODS Interaction of dendriplexes with lipid membranes was measured by fluorescence anisotropy, dynamic light scattering and Langmuir-Blodgett techniques. The morphology of the complexes was examined by transmission electron microscopy. RESULTS All dendriplexes independent of the type of peptide interacted with model lipid membranes. Negatively charged vesicles composed of a mixture of DMPC/DPPG interacted more strongly, and it was accompanied by an increase in anisotropy of the fluorescent probe localized in polar domain of lipid bilayers. There was also an increase in surface pressure of the lipid monolayers. Mixing negatively charged liposomes with dendriplexes increased liposome size and made their surface charges more positive. CONCLUSIONS HIV-peptide/dendrimer complexes interact with model lipid membranes depending on their surface charge. Carbosilane dendrimers can be useful as non-viral carriers for delivering HIV-peptides into cells.

Abstract
Vaginal drug administration can improve prophylaxis and treatment of many conditions affecting the female reproductive tract, including sexually transmitted diseases, fungal and bacterial infections, and cancer. However, achieving sustained local drug concentrations in the vagina can be challenging, due to the high permeability of the vaginal epithelium and expulsion of conventional soluble drug dosage forms. Nanoparticle-based drug delivery platforms have received considerable attention for vaginal drug delivery, as nanoparticles can provide sustained release, cellular targeting, and even intrinsic antimicrobial or adjuvant properties that can improve the potency and/or efficacy of prophylactic and therapeutic modalities. Here, we review the use of polymeric nanoparticles, liposomes, dendrimers, and inorganic nanoparticles for vaginal drug delivery. Although most of the work toward nanoparticle-based drug delivery in the vagina has been focused on HIV prevention, strategies for treatment and prevention of other sexually transmitted infections, treatment for reproductive tract cancer, and treatment of fungal and bacterial infections are also highlighted.

Structural characterization of lyotropic liquid crystals containing a dendrimer for solubilization and release of gallic acid. Colloids Surf B Biointerfaces 2013; 112:87-95. [PMID: 23973908 DOI: 10.1016/j.colsurfb.2013.06.051] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2013] [Revised: 06/18/2013] [Accepted: 06/21/2013] [Indexed: 12/31/2022]
Abstract
The role of 2nd generation polypropyleneimine (PPIG2) dendrimer in controlling the release of gallic acid (GA) as a model drug from lyotropic liquid crystal was explored. GA (0.2wt%) was solubilized in three types of mesophases: lamellar (Lα), cubic (space group of Ia3d, Q(G)), and reverse hexagonal (HII), composed of GMO and water (and d-α-tocopherol, or tricaprylin in the case of HII mesophases). Small angle X-ray scattering (SAXS) and attenuated total reflectance Fourier transform infrared (ATR-FTIR) along with UV spectrophotometry were utilized to elucidate the structure modifications and release resulting from the cosolubilization of GA and PPIG2. Solubilization of PPIG2 into Lα and Q(G) phases caused transformation of both structures to HII. The diffusion of GA out of the mesophases was found to be dependent on water content and PPIG2 concentration. Rapid release from Lα+PPIG2 and Q(G)+PPIG2 mesophases was recorded. The release from both HII mixtures (with d-α-tocopherol and tricaprylin) was shown to be dependent on the type of oil. Release studies conducted for 72h showed that GA release can be modulated and sustained by the presence of PPIG2, supposedly due to the electrostatic interactions between the dendrimer and the drug molecule.

Abstract
The present treatments for HIV transfection include chemical agents and gene therapies. Although many chemical drugs, peptides and genes have been developed for HIV inhibition, a variety of non-ignorable drawbacks limited the efficiency of these materials. In this review, we discuss the application of dendrimers as both therapeutic agents and non-viral vectors of chemical agents and genes for HIV treatment. On the one hand, dendrimers with functional end groups combine with the gp120 of HIV and CD4 molecule of host cell to suppress the attachment of HIV to the host cell. Some of the dendrimers are capable of intruding into the cell and interfere with the later stages of HIV replication as well. On the other hand, dendrimers are also able to transfer chemical drugs and genes into the host cells, which conspicuously increase the anti-HIV activity of these materials. Dendrimers as therapeutic tools provide a potential treatment for HIV infection.
