Kamra, Mohini;Maiti, Bappa;Saha, Pranay;Karande, Anjali A.;Bhattacharya, Santanu research published 《 Antibody-Conjugated Vitamin E-Derived Liposomes for Targeted Gene Transfer》, the research content is summarized as follows. Construction of a vitamin E-based liposomal biomaterial and its ability to deliver therapeutic genes selectively across liver cancer cells are demonstrated herein. In humans, liver regulates the levels of α-tocopherol, i.e., vitamin E, and hepatic cells carry the machinery for its transport. To exploit the presence of tocopherol transport protein, we have selected an efficient gene transfecting α-tocopherol-based twin lipid bearing a hydroxyethylated headgroup and octamethylene spacer (TH8S) for liposome formation. Also, based on the abundance of the low-d. lipoprotein receptor (LDLr) on the cellular surface in the case of hepatocellular carcinoma, anti-LDLr monoclonal antibody is used to confer the targeting ability to liposomes. A facile thiol-maleimide click chem. is used for antibody decoration on the liposomal surface. Selective delivery of reporter and therapeutic genes (GFP and p53) to cells of hepatic origin was observed using anti-LDLr-tagged TH8S liposomes. Cellular internalization by receptor-mediated endocytosis renders the bioconjugate highly specific as well as highly efficient. Compatibility of the designed material with human blood points to its safety of use in systemic circulation thereby highlighting its in vivo potential. Thus, we report here a versatile biomaterial derived from an essential vitamin that promises potential for targeted suicidal gene therapy.

Kanagasundaram, Thines;Laube, Markus;Wodtke, Johanna;Kramer, Carsten Sven;Stadlbauer, Sven;Pietzsch, Jens;Kopka, Klaus research published 《 Radiolabeled Silicon-Rhodamines as Bimodal PET/SPECT-NIR Imaging Agents》, the research content is summarized as follows. Radiolabeled fluorescent dyes are decisive for bimodal imaging as well as highly in demand for nuclear- and optical imaging. Silicon-rhodamines (SiRs) show unique near-IR (NIR) optical properties, large quantum yields and extinction coefficients as well as high photostability. Here, we describe the synthesis, characterization and radiolabeling of novel NIR absorbing and emitting fluorophores from the silicon-rhodamine family for use in optical imaging (OI) combined with positron emission tomog. (PET) or single photon emission computed tomog. (SPECT), resp. The presented photostable SiRs were characterized using NMR-, UV-Vis-NIR-spectroscopy and mass spectrometry. Moreover, the radiolabeling conditions using fluorine-18 or iodine-123 were extensively explored. After optimization, the radiofluorinated NIR imaging agents were obtained with radiochem. conversions (RCC) up to 70% and isolated radiochem. yields (RCY) up to 54% at molar activities of g.t. 70 GBq/μmol. Radioiodination delivered RCCs over 92% and allowed to isolate the ¹²³I-labeled product in RCY of 54% at a molar activity of g.t. 7.6 TBq/μmol. The radiofluorinated SiRs exhibit in vitro stabilities g.t. 70% after two hours in human serum. The first described radiolabeled SiRs are a promising step toward their further development as multimodal PET/SPECT-NIR imaging agents for planning and subsequent imaging-guided oncol. surgery.

2-Bromophenylboronic acid is a glucose monitoring agent that has a ruthenium complex with an acidic environment. The nitro group and the amines are in close proximity to the boron center, and this proximity leads to a high nucleophilic character of the molecule. This reactivity allows 2-bromophenylboronic acid to be used as a fluorescence probe for acidic environments. 2-Bromophenylboronic acid also inhibits secretase enzymes, which are involved in Alzheimer’s disease and other neurodegenerative disorders. It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., Related Products of 244205-40-1

Kanakala, Madhu Babu;Yelamaggad, Channabasaveshwar V. research published 《 Exceptional dual fluorescent, excited-state intramolecular proton-transfer (ESIPT) columnar liquid crystals characterized by J-stacking and large Stokes shifts》, the research content is summarized as follows. Herein the synthesis, characterization, and ESIPT activity of a homologous series of novel phasmidic bis(N-salicylideneaniline) Col LCs. was reported. Optical microscopic, calorimetric and powder X-ray diffraction (XRD) studies evidence the occurrence of hexagonal columnar (Colh) phase having p6mm symmetry where the constituent slices result from the self-assembly of a pair of mesogens in a side-by-side manner facilitated by intense longitudinal π-π interactions. X-ray data confirm the absence of both directionally correlated tilting of the slices and transverse core-core interactions within the columns. Fluorescence probing clearly evidence the ESIPT occurring not only in DCM solution of the mesogens but also in their three-condensed states viz., solid, liquid crystal, and isotropic liquid phase; in general, two archetypal emission bands at ∼430 nm (weak) and ∼ 630 nm (strong) with large Stokes shifts (250-275 nm) of ESIPT phenomenon was observed The slow shift of emission maxima of the ESIPT fluorescence as a function of decreasing temperature without photoluminescence quenching coupled with the estimated tilt angle (θ) of the slices normal to the columnar axis (37 to 42°), from the XRD data, confirmed the formation of so-called Scheibe or J-aggregates. The redox activity, metal ion sensing ability, and solvatochromism of the mesogens was also investigated. The study suggests that these ESIPT Col LCs with band-gap of about 3 eV can be regarded as wide-bandgap semiconducting materials having the electronic characteristics falling between those of conventional semiconductors and insulators.

3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
