    Abstract

    Polymerization‐induced phase separation takes place when a miscible component of the monomer becomes immiscible as the polymer is formed. One example is the polymerization of methyl methacrylate (MMA) in the presence of poly(ethylene glycol) (PEG). Depending on the initial conditions, microscopic structures, including porous structures, co‐continuous monolith structures, and particle aggregation structures, are obtained. In this study, the phase separation process is analyzed using an optical microscope and fluorescence microscope. The nucleation or spinodal decomposition in the initial stage, subsequent growth in the microscopic domains, and eventual fixation of the structure are observed. The observed images are analyzed using image analysis software. The particle number and the particle size as a function of reaction time are evaluated. Conversion and molecular weight distribution as a function of reaction time are also analyzed.

    Dendrimers are potent nanocarriers in drug delivery systems because their structure can be precisely controlled. We previously reported that polyamidoamine (PAMAM) dendrimers that were modified with 1,2-cyclohexanedicarboxylic acid (CHex) and phenylalanine (Phe), PAMAM-CHex-Phe, exhibited an effective association with various immune cells, including T-cells. In this study, we synthesized various carboxy-terminal Phe-modified dendrimers with different linkers using phthalic acid and linear dicarboxylic acids to determine the association of these dendrimers with Jurkat cells, a T-cell model. PAMAM-n-hexyl-Phe demonstrated the highest association with Jurkat T-cells. In addition, dendri-graft polylysine (DGL) with CHex and Phe, DGL-CHex-Phe, was synthesized, and its association with Jurkat cells was investigated. The association of DGL-CHex-Phe with T-cells was higher than that of PAMAM-CHex-Phe. However, it was insoluble in water and thus it is unsuitable as a drug carrier. Model drugs, such as protoporphyrin IX and paclitaxel, were loaded onto these dendrimers, and the most model drug molecules could be loaded into PAMAM-CHex-Phe. PTX-loaded PAMAM-CHex-Phe exhibited cytotoxicity against Jurkat cells at a similar level to free PTX. These results suggest that PAMAM-CHex-Phe exhibited both efficient T-cell association and drug loading properties.

    The 2-methacryloyloxyethyl phosphorylcholine (MPC) polymers are mimetic to phospholipids, being widely used as biocompatible polymers. In our previous study, MPC polymer hydrogels proved more effective for optical tissue clearing compared to acrylamide (AAm) polymer hydrogels. In the present study, 2-acryloyloxyethyl phosphorylcholine (APC) was synthesized and employed to create hydrogels for a comparative analysis with methacrylic MPC-based hydrogels. APC, an acrylic monomer, was copolymerized with AAm in a similar reactivity. In contrast, MPC, as a methacrylic monomer, demonstrated higher copolymerization reactivity than AAm, leading to a spontaneously delayed two-step polymerization behavior. This suggests that the polymer sequences and network structures became heterogeneous when both methacrylic and acrylic monomers, as well as crosslinkers, were present in the copolymerization system. The molecular weight of the APC polymers was considerably smaller than that of the MPC polymers due to the formation of mid-chain radicals and subsequent β-scission during polymerization. The swelling ratios in water and strain sweep profiles of hydrogels prepared using acrylic and methacrylic compounds differed from those of hydrogels prepared using only acrylic compounds. This implies that copolymerization reactivity influences the polymer network structures and crosslinking density in addition to the copolymer composition. APC-based hydrogels are effective for the optical clearing of tumor tissues and are applicable to both passive and electrophoretic methods.

    Abstract

    The tumor microenvironment (TME) strongly affects the clinical outcomes of immunotherapy. This study aimed to activate the antitumor immune response by manipulating the TME by transfecting genes encoding relevant cytokines into tumor cells using a synthetic vehicle, which is designed to target tumor cells and promote the expression of transfected genes. Lung tumors were formed by injecting CT26.WT intravenously into BALB/c mice. Upon intravenous injection of the green fluorescent protein‐coding plasmid encapsulated in the vehicle, 14.2% tumor‐specific expression was observed. Transfection of the granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) and CD40 ligand (L)‐plasmid combination and interferon gamma (IFNγ) and CD40L‐plasmid combination showed 45.5% and 54.5% complete remission (CR), respectively, on day 60; alternate treatments with both the plasmid combinations elicited 66.7% CR, while the control animals died within 48 days. Immune status analysis revealed that the density of dendritic cells significantly increased in tumors, particularly after GM‐CSF‐ and CD40L‐gene transfection, while that of regulatory T cells significantly decreased. The proportion of activated killer cells and antitumoral macrophages significantly increased, specifically after IFNγ and CD40L transfection. Furthermore, the level of the immune escape molecule programmed death ligand‐1 decreased in tumors after transfecting these cytokine genes. As a result, tumor cell‐specific transfection of these cytokine genes by the synthetic vehicle significantly promotes antitumor immune responses in the TME, a key aim for visceral tumor therapy.

    Although T cells play important roles in various immune reactions, there are only a few reports on delivery systems into T cells. Our previous study showed that carboxy-terminal phenylalanine (Phe)-modified polyamidoamine (PAMAM) dendrimers have both temperature- and pH-sensitive properties, which are affected by the chemical structure. The self-assembled structures of Phe, observed in phenylketonuria, enhance the protein aggregation, the association with the cell membrane and the membrane permeability. In this study, we applied the Phe-modified dendrimers to a pH-sensitive drug delivery system into T cells. Dendrimers with different amino acids and acid anhydrides were synthesized, and their pH-responsive association with T cells and their subsets was investigated. The dendrimers modified with Phe and cyclohexanedicarboxylic acid (CHex) showed higher uptake into various cells, including Jurkat cells, CD3+ T cells, CD3 + CD4+ helper T cells and CD3 + CD8+ killer T cells. These dendrimers were internalized into T cells via endocytosis, and their cellular uptake was enhanced under weak acidic conditions (pH 6.5). Our results showed that Phe- and CHex-modified dendrimers have a delivery potential to T cells and their subsets, which may be useful for cancer immunotherapy.

    It has been reported that the amount of intermediate water, defined as water molecules loosely bound to a material, is a useful index of the material's bio-inert properties. Polyethylene glycol (PEG) is a well-known biocompatible polymer with a large amount of intermediate water. Many researchers have showed that PEGylated nanoparticles are passively accumulated in tumor tissues owing to their enhanced permeability and retention (EPR) effects. Dendrimers are regularly branched polymers with highly controllable size and structure, which can be exploited as potent drug carriers. In this study, we investigated the tripartite relationship among the PEG density, the hydration state, and the passive tumor targeting property, using PEGylated dendrimers. The fully PEGylated dendrimer, PEG64-den, showed similar hydration behavior to PEG and a passive tumor targeting property. In contrast, the hydration state of the partly PEGylated dendrimer, PEG5-den, was different from that of PEG64-den, and the passive tumor targeting property was not observed. This is the first report to show the hydration state of a drug carrier as well as discuss a relationship between the hydration state and biodistribution.

    Zwitterionic polymers have both anion and cation groups in the side chain and have been used in various biomedical applications because of the unique properties. In this study, zwitterionic polymer hydrogels are applied to optical tissue clearing for 3D fluorescence imaging. Polyacrylamide hydrogels have been employed in Clear Lipid-exchanged Acrylamide-hybridized Rigid Imaging/Immunostaining/In situ-hybridization-compatible Tissue-hYdrogel method. Zwitterionic polymer hydrogels are produced using zwitterionic monomers, such as 3-[(3-acrylamidopropyl)dimethylammonio]propane-1-sulfonate (DAPS) and 2-methacryloyloxyethyl phosphorylcholine (MPC), and crosslinkers. The hydrogels made from poly(DAPS-co-acrylamide) and MPC homopolymers afford the most transparent tumor tissues. However, the tissues cleared using DAPS copolymers-containing hydrogels became turbid in a refractive index-matching solution, which are unable to obtain clear 3D fluorescence images. In contrast, the 3D fluorescence imaging is achieved in the MPC polymer-treated 2-mm-thick brain slices after immunostaining. The 3D fluorescence imaging of lung metastasis that is cleared by the MPC hydrogel to demonstrate the possible application to cancer diagnosis is performed. The results indicate the increased potentials of zwitterionic polymer hydrogels, especially MPC polymer hydrogels, in biomedical applications.

    The development of drug delivery vehicles to cancer and/or immune cells in lymph nodes is important for cancer diagnosis, therapy, and immunotherapy. We previously reported that anionic carboxyl-terminal dendrimers were accumulated in lymph nodes. In this study, three anionic dendrimers with carboxyl-, sulfonyl-, and phosphate-terminal groups were prepared to examine the lymph node targeting and the association with immune cells in the lymph nodes. These anionic dendrimers were accumulated in the lymph node by intradermal injection. Although the carboxyl- and sulfonyl-terminal dendrimers were diffused from the injection site, the phosphate-terminal dendrimers were mostly retained. The phosphate-terminal dendrimer was recognized by the macrophages, dendritic cells, and B cells in the lymph node, whereas the carboxyl- and sulfonyl-terminal dendrimers were not. Our results show that these anionic dendrimers were accumulated in the lymph node where the association with immune cells could be controlled by the terminal structure of the dendrimer. The phosphate-terminal dendrimer can be used as a nanoplatform for the delivery of some bioactive molecules to some immune cells, including B cells, in the lymph node.

    Metastasis is a characteristic property of cancer cells, which degrade extracellular matrix containing collagen. We prepared a polymer prodrug-embedded collagen gel for metastasis-associated drug delivery. A collagen peptide-modified dendrimer that attached doxorubicin (Dox) via a pH-degradable linkage was synthesized as a polymer prodrug. Compared with free Dox, the diffusion of the dendrimer prodrug from the collagen gel was suppressed. Highly invasive MDA-MB-231 cells were more sensitive to the prodrug-hybrid collagen gel than poorly invasive MCF-7 cells, even though the cytotoxicity of the dendrimer prodrug by itself against these cells was almost identical. The cytotoxicity against MDA-MB-231 cells decreased in the presence of a matrix metalloproteinase (MMP) inhibitor, suggesting that the dendrimer prodrug/collagen hybrid gel was affected by MMP activity. The dendrimer prodrug/collagen hybrid gel not only suppressed tumor growth but also attenuated metastatic activity in vivo. Therefore, the dendrimer prodrug-embedded collagen gel is useful for cancer chemotherapy.

    Temperature-responsive polymers are classified into LCST type which becomes turbid upon heating and UCST type which dissolves upon heating, which have used as intelligent materials in various fields. In this study, we found that carboxy-terminal dendrimers containing phenylalanine (Phe), a hydrophobic amino acid, exhibited a unique property that allows them to switch between LCST-type and UCST-type properties depending on pH. These dendrimers after the intradermal injection were useful for delivery into in lymph node-resident various immune cells, including T cells which had been difficult to deliver.

    Because cancer is a leading cause of death in Japan, development of imaging technology for cancer diagnosis and drug delivery systems for cancer therapy are crucial. Dendrimers are synthetic macromolecules with highly controllable structures, which are potent multifunctional imaging agents and drug carriers. The detection of the sentinel lymph node (SLN), the first lymph node draining tumor cells, is important in cancer diagnosis and therapy. First, the optimal dendrimer structure for SLN imaging was investigated. Carboxyl-terminal dendrimers of greater than G4 were mostly located in the SLN. SLN detection was successfully performed by nuclear medicinal imaging and fluorescent imaging using these dendrimers. Finally, triply functional dendrimers with tumor targeting activities, antitumor effects and detectable probes were prepared.

    We have tried to clarify a principle to convert the characteristics of collective modes of electronic excited states in a nanoparticle-assembled system into "macroscopic flow" via photothermal effect, and aimed at the application to nano-bioscience. When each dispersion liquid of diluted egg white or egg yolk was added into the dispersion liquid of spherical-shell type metallic nanoparticle-assembled structures, laser was irradiated with each mixture and included proteins were detected via thermal solidification due to enhanced photothermal effect arising from collective effect of localized surface plasmon therein. Particularly, the required time for bubble generation and thermal solidification was different depending on the component in each sample. Also, we have clarified the condition for the assembling organic nanocapsules including gold nanoparticles into the aimed position in their dispersion liquid by laser irradiation.

    The aim of this study is the development of bottom-up fabrication of nanocomposites by the light irradiation and the chemical surface modification, which would contribute to nano-bioscience. By irradiating doughnut-shaped laser beam on the dispersion liquid of Ag nanoparticles (NPs) with various shapes, we have theoretically and experimentally demonstrated selective assembling of NPs with highly uniform size and shape. It is expected that such a control of uniformity of NPs can be utilized in wide research fields, for example, the property control of photoresponsive NPs for the highly sensitive biosensor and the medical application. Furthermore, we have succeeded in the detection of a small amount of heat coagulation proteins by probe particles with high photothermal effect, and have succeeded in the destruction of pathogenetic cells by optimized photothermogenetic metallic NPs.

    The aim of this study is to develop novel CT contrast agent with a longer retention in blood in order to visualize vascular structure in a target tissue or angiogenesis of tumor. For this purpose, we use iodine or gold as a contrast element and human serum albumin or dendrimer modified with PEG as a carrier compound. Iodine modified agent showed a less enhancement effect in vivo because of its instability in blood. Gold modified agent showed a longer enhancement effect in vivo in comparison with a commercially available iodine contrast agent.

    We have studied drug delivery system involving metastasis for cancer therapy. Collagen gels containing drug-conjugated dendrimer exhibited the selective drug action against highly metastatic breast tumor cells. In this study, drug-conjugated poly(glutamic acid) enhanced the selectivity in metastasis, and modification of collagen peptide was influenced on the drug action. Collagen peptide-modified dendrimer with anticancer drugs via hydrazone bond showed the antitumor growth activity. Therefore, this kind of material is useful for a novel type of drug delivery system.

    厚生労働省の統計によると、日本の三大死因は悪性新生物(癌)、心疾患、脳血管疾患である。特に、癌による死亡数は年々増加傾向にあり、癌治療技術の発展は急務である。本研究では、転移性乳癌細胞を標的とした新しいドラッグデリバリーシステム(DDS)を提案する。
    まず、本年度は、薬物運搬デンドリマーの作製を行った。市販のG4のPAMAMデンドリマーの末端のアミノ基にBoc-Glu(OBzl)(Boc基で保護したグルタミン酸-gammaベンジルエステル)を反応させた後、トリフルオロ酢酸(TFA)によってBoc基を除去した。得られた化合物は^1H,^<13>C-NMRによって同定した。続いて、ポリエチレングリコールモノメチルエーテル(分子量2000)の水酸基にクロロ蟻酸-4-ニトロフェニルを反応させることによって、アミノ基への反応性を付与し、デンドリマーと結合させた。得られた化合物は^1H-NMR、GPCによって同定を行った。また、GPP(グリシン-プロリン-プロリン)の繰り返し配列の合成を行った。Gly-OBzl(OBzl基で保護したグリシン)とBoc-Pro(Boc基で保護したプロリン)を、HBTUを用いて縮合反応させ、シリカゲルカラムによって精製した。Boc基をTFAによって除去した後、さらにBoc-ProをHBTUを用いて結合させた。得られたトリペプチドを二グループに分け、一方はTFAによってBoc基を除去し、もう一方は接触還元によりOBzl基を除去した。得られたトリペプチドは^1H,^<13>C-NMR、HPLCによって同定した。これらのトリペプチドを縮合させ、ヘキサペプチド(PPGPPG)を合成した。この化合物のOBzl基を接触還元により除去して、アミノ基に反応性をもったヘキサペプチドを合成した。

    In this study, we attempted to develop highly efficient nonviral vectors with multi-functions according to two different approaches, namely liposome-based systems with fusogenic polymers and dendrimer-based systems. First, we prepared complexes of lipoplexes and liposomes modified with pH-sensitive fusogenic polymer, succinylated poly(glycidol) with transferrin, which is a cancer cell-specific ligand. We found that the complexation of the fusogenic polymer-modified liposomes enhanced ability of the lipoplexes as gene vectors. We also examined the influence of the complex size on its transfection activity and found that decrease in the size resulted in increase in transfection activity. The obtained complexes with small size exhibited high transfection activity in the presence of serum proteins, which often decreases transfection activity of gene vectors. We further attempted to improve transfection activity of the lipoplexes-fusogenic liposomes complexes by increasing fusogenic ability of the liposomes. For this purpose, we synthesized several fusogenic polymers with hydrophobic side groups. We found that fusogenic activity of the polymers increased with increasing hydrophobicity of the polymers. In addition, transfection activity of the complexes of the lipoplexes and polymer-modified liposomes exhibited extremely high transfection activity when the polymer with the highest fusogenic activity was used for the liposome modification. It was noteworthy that the obtained complexes achieved efficient transfection of DC 2.4, which is derived from dendritic cell. On the other hand, we also attempted to develop a new type of synthetic vector by using dendritic molecules, which achieve efficient transfection through so-called proton sponge effect. We prepared a new family of cationic lipids, which consist of a polyamidoamine dendron moiety and two long alkyl groups. These molecules formed complexes with DNA. The obtained complexes achieved efficient transfection of cells through a synergetic action of the proton sponge effect and membrane fusion. In addition, we attached polyethylene glycol chains to all chain ends of the dendron moiety. The obtained polyethylene glycol-modified dendron-bearing lipids were found to be useful for preparation of vectors with colloidal stability and high transfection activity. We believe that information obtained through this study will contribute for establishment of safe and efficient gene therapy.
