Abstract
A brain tumor is an uncontrolled cell proliferation, a mass of tissue composed of cells that grow and divide abnormally and appear to be uncontrollable by the processes that normally control normal cells. Approximately 25,690 primary malignant brain tumors are discovered each year, 70% of which originate in glial cells. It has been observed that the blood-brain barrier (BBB) limits the distribution of drugs into the tumour environment, which complicates the oncological therapy of malignant brain tumours. Numerous studies have found that nanocarriers have demonstrated significant therapeutic efficacy in brain diseases. This review, based on a non-systematic search of the existing literature, provides an update on the existing knowledge of the types of dendrimers, synthesis methods, and mechanisms of action in relation to brain tumours. It also discusses the use of dendrimers in the diagnosis and treatment of brain tumours and the future possibilities of dendrimers. Dendrimers are of particular interest in the diagnosis and treatment of brain tumours because they can transport biochemical agents across the BBB to the tumour and into the brain after systemic administration. Dendrimers are being used to develop novel therapeutics such as prolonged release of drugs, immunotherapy, and antineoplastic effects. The use of PAMAM, PPI, PLL and surface engineered dendrimers has proven revolutionary in the effective diagnosis and treatment of brain tumours.

Molecules 2021; 26:6552. [PMID: 34770963 PMCID: PMC8588109 DOI: 10.3390/molecules26216552] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Revised: 10/25/2021] [Accepted: 10/25/2021] [Indexed: 12/20/2022] Open
Abstract
Novel peptide dendrimer with Lys-2His repeating units was recently synthesized, studied by NMR (Molecules, 2019, 24, 2481) and tested as a nanocontainer for siRNA delivery (Int. J. Mol. Sci., 2020, 21, 3138). Histidine amino acid residues were inserted in the spacers of this dendrimer. Increase of their charge with a pH decrease turns a surface-charged dendrimer into a volume-charged one and should change all properties. In this paper, the molecular dynamics simulation method was applied to compare the properties of the dendrimer in water with explicit counterions at two different pHs (at normal pH with neutral histidines and at low pH with fully protonated histidines) in a wide interval of temperatures. We obtained that the dendrimer at low pH has essentially larger size and size fluctuations. The electrostatic properties of the dendrimers are different but they are in good agreement with the theoretical soft sphere model and practically do not depend on temperature. We have shown that the effect of pairing of side imidazole groups is much stronger in the dendrimer with neutral histidines than in the dendrimer with protonated histidines. We also demonstrated that the capacity of a nanocontainer based on this dendrimer with protonated histidines is significantly larger than that of a nanocontainer with neutral histidines.

Why the Orientational Mobility in Arginine and Lysine Spacers of Peptide Dendrimers Designed for Gene Delivery Is Different? Int J Mol Sci 2020; 21:E9749. [PMID: 33371242 PMCID: PMC7766995 DOI: 10.3390/ijms21249749] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 12/06/2020] [Accepted: 12/08/2020] [Indexed: 12/12/2022] Open
Abstract
New peptide dendrimer with Lys-2Arg repeating units was recently studied experimentally by NMR (RSC Advances, 2019, 9, 18018) and tested as gene carrier successfully (Int. J. Mol. Sci., 2020, 21, 3138). The unusual slowing down of the orientational mobility of 2Arg spacers in this dendrimer was revealed. It has been suggested that this unexpected behavior is caused by the Arg-Arg pairing effect in water, which leads to entanglements between dendrimer branches. In this paper, we determine the reason for this slowing down using atomistic molecular dynamics simulation of this dendrimer. We present that the structural properties of Lys-2Arg dendrimer are close to those of the Lys-2Lys dendrimer at all temperatures (Polymers, 2020, 12, 1657). However, the orientational mobility of the H-H vector in CH2-N groups of 2Arg spacers in Lys-2Arg dendrimer is significantly slower than the mobility of the same vector in the Lys-2Lys dendrimer. This result is in agreement with the recent NMR experiments for the same systems. We revealed that this difference is not due to the arginine-arginine pairing, but is due to the semiflexibility effect associated with the different contour length from CH2-N group to the end of the side arginine or lysine segment in spacers.

Abstract
Transfecting nucleic acids into cells is an essential procedure in biological research usually performed using nonviral transfection reagents. Unfortunately, most transfection reagents have polymeric or undisclosed structures and require nonstandard synthetic procedures. Herein we report peptide dendrimers accessible as pure products from standard building blocks by solid-phase peptide synthesis and acting as nontoxic single component siRNA transfection reagents for a variety of cell lines with equal or better performance than the gold standard lipofectamine L2000. Structure-activity relationships and mechanistic studies illuminate their transfection mechanism in unprecedented detail. Stereoselective dendrimer aggregation via intermolecular β-sheets at neutral pH enables siRNA complexation to form nanoparticles which enter cells by endocytosis. Endosome acidification triggers protonation of amino termini and rearrangement to an α-helical conformation forming smaller dendrimer/siRNA nanoparticles, which escape the endosome and release their siRNA cargo in the cytosol. Two particularly efficient d-enantiomeric dendrimers are proposed as new reference reagents for siRNA transfection.

Abstract
Glioblastoma Multiforme (GBM) is one of the most aggressive forms of all cancers. The median survival with current standard-of-care radiation and chemotherapy is about 14months. GBM is difficult to treat due to heterogeneity in cancer cell population. MicroRNA-based drugs have rapidly become a vast and burgeoning field due to the ability of a microRNA (miRNA) to target many genes involved in key cellular pathways. However, in vivo delivery of miRNA remains a crucial challenge for its therapeutic success. To bypass this shortcoming, we designed polymeric nanogels (NGs), which are based on a polyglycerol-scaffold, as a new strategy of miRNA delivery for GBM therapy. We focused on miR-34a, which is known for its key role in important oncogenic pathways and its tumor suppression ability in GBM and other cancers. We evaluated the capability of six NG derivatives to complex with miR-34a, neutralize its negative charge and deliver active miRNA to the cell cytoplasm. Human U-87 MG GBM cells treated with our NG-miR-34a nano-polyplexes showed remarkable downregulation of miR-34a target genes, which play key roles in the regulation of apoptosis and cell cycle arrest, and induce inhibition of cells proliferation and migration. Administration of NG-miR-34a nano-polyplexes to human U-87 MG GBM-bearing SCID mice significantly inhibited tumor growth as opposed to treatment with NG-negative control miR polyplex or saline. The comparison between different polyplexes highlighted the key features for the rational design of polymeric delivery systems for oligonucleotides. Taken together, we expect that this new therapeutic approach will pave the way for safe and efficient therapies for GBM.
