Ho, Thanh C.;Tius, Marcus A.;Nikas, Spyros P.;Tran, Ngan K.;Tong, Fei;Zhou, Han;Zvonok, Nikolai;Makriyannis, Alexandros research published 《 Oxa-adamantyl cannabinoids》, the research content is summarized as follows. As a continuation of earlier work on classical cannabinoids bearing bulky side chains we report here the design, synthesis, and biol. evaluation of 3′-functionalized oxa-adamantyl cannabinoids as a novel class of cannabinergic ligands. Key synthetic steps involve nucleophilic addition/transannular cyclization of aryllithium to epoxyketone in the presence of cerium chloride and stereoselective construction of the tricyclic cannabinoid nucleus. The synthesis of the oxa-adamantyl cannabinoids is convenient, and amenable to scale up allowing the preparation of these analogs in sufficient quantities for detailed in vitro evaluation. The novel oxa-adamantyl cannabinoids reported here were found to be high affinity ligands for the CB1 and CB2 cannabinoid receptors. In the cyclase assay these compounds were found to behave as potent and efficacious CB1 receptor agonists. Isothiocyanate analog AM10504 (I) is capable of irreversibly labeling both the CB1 and CB2 receptors.

1-Bromo-3,5-dimethoxybenzene (1BDMB) is a synthetic molecule that can be used as an electron acceptor in organic photovoltaic cells. 1BDMB is a salt of the sodium salt of resorcylic acid and 1,3-dibromo-5,5-dimethoxybenzene. It has been shown to have a radical mechanism for the generation of free radicals. The radical mechanism is initiated by light absorption by the ruthenium complex at the center of the molecule which induces photoinduced electron transfer from the ruthenium to 1BDMB. This process results in electron transfer from the donor to an acceptor molecule, such as oxygen or nitrogen. The pharmacokinetic properties of this compound are not well known; however, it has been demonstrated that it can be synthesized through a cross-coupling reaction with other aromatic compounds such as stemofuran., Recommanded Product: 1-Bromo-3,5-dimethoxybenzene

Ho, Vuong Thi Thanh Xuan;Park, Haebeen;An, Seeun;Kim, Gun;Ly, Nguyen Hoang;Lee, So Yeong;Choo, Jaebum;Jung, Hyo Sung;Joo, Sang-Woo research published 《 Coumarin-lipoic acid conjugates on silver nanoparticle-supported nanopipettes for in situ dual-mode monitoring of intracellular Cu(II) and potential chemodynamic therapy applications》, the research content is summarized as follows. Intracellular Cu(II) in the human body is essential to many physiol. functions, and its disruption is connected to several diseases. Synthetic coumarin-lipoic acid (Cou-LA) conjugate-functionalized silver-nanoparticles decorated on nanopipettes (CSNs) were fabricated herein for the determination of intracellular Cu(II) via in situ dual Raman/fluorescence spectroscopy. The CSNs selectively sensed Cu(II) over other metal ions to induce enhanced Raman intensities and fluorescence quenching. The determination of Cu(II) in single HeLa cells was achieved in accordance with changes in the ratio of Raman intensities at 500 and 597 cm^-1 and fluorescence at 469 nm, which was ascribed to the capturing of Cu(II) by the CSNs. The Raman signals exhibited a good linear relationship with Cu(II) concentration from 10 to 75 μM with R² = 0.956. The calibration curve indicated a local Cu(II) concentration of ∼42.6 ± 8.6 μM in a single HeLa cell after pretreatment with 100 μM Cu(II) for 1 h. Cou-LA exhibited negligible cytotoxicity in both normoxic and hypoxic HeLa cells. However, a significant reduction in cell viability occurred with the Cu(II)-Cou-LA complex. This cytotoxicity was attributed to the generation of reactive oxygen species via a Cu-catalyzed Fenton-like process in tumor microenvironments and was found to be applicable to chemodynamic therapy (CDT). The system fabricated in this study represents a novel strategy for intracellular dual-mode Cu(II) detection and CDT applications in cancer research.

Hollmann, Tim;Berkhan, Gesche;Wagner, Lisa;Sung, Kwang Hoon;Kolb, Simon;Geise, Hendrik;Hahn, Frank research published 《 Biocatalysts from biosynthetic pathways: Enabling stereoselective, enzymatic cycloether formation on a gram scale》, the research content is summarized as follows. Biosynthetic pathways of natural products contain many enzymes that contribute to the rapid assembly of mol. complexity. Enzymes that form complex structural elements with multiple stereocenters, like chiral saturated oxygen heterocycles (CSOH), are of particular interest for a synthetic application, as their use promises to significantly simplify access to these elements. Here, the biocatalytic characterization of AmbDH3, an enzyme that catalyzes intramol. oxa-Michael addition (IMOMA) is reported. This reaction essentially gives access to various types of CSOH with adjacent stereocenters, but it is not yet part of the repertoire of preparative biocatalysis. An in-depth study on the synthetic utility of AmbDH3 was performed, which made extensive use of complex synthetic precursor surrogates. The enzyme exhibited stability and broad substrate tolerance in in vitro experiments, which was in agreement with the results of mol. modeling. Its selectivity profile enabled kinetic resolution of chiral tetrahydropyrans (THPs) under control of up to four stereocenters. A systematic optimization of the reaction conditions enabled gram-scale conversions yielding preparative amounts of chiral THP. The synthetic utility of AmbDH3 was finally demonstrated by its successful application in the key step of a chemoenzymic total synthesis to the THP-containing phenylheptanoid (-)-centrolobine. These results highlight the synthetic potential of AmbDH3 and related IMOMA cyclases as a biocatalytic alternative that further develops the available chem.-synthetic IMOMA methodol.

The thermal behavior, including the cold crystallization, of alkyl-derivatized Sudan III (1-[4-(phenylazo)phenylazo]-2-naphthol), SD3-OCn, was investigated. Its structural flexibility due to the two azo groups caused the formation of plural crystal structures, which further resulted in complex cold crystallization A metastable nonflat structure and a thermodynamically stable flat structure resulted in the two sets of crystallization and melting behavior during the heating process. Further, the change in the alkyl chain length caused variations in the crystallization rate and crystallinity, thus systematically changing the cold crystallization behavior. It was proven that the high mobility of the Ph group triggered supercooling and cold crystallization and that the alkyl chain correspondingly controlled the thermal behavior.

Honda, Akinori;Hibi, Yukie;Matsumoto, Kazuma;Kawai, Masato;Miyamura, Kazuo research published 《 Alkyl substituent-dependent systematic change in cold crystallization of azo molecules》, the research content is summarized as follows. The thermal behavior of alkyl-derivatized 1-(2,4-dimethylphenylazo)-4-naphthol and 1-(2,4-dimethylphenylazo)-2-naphthol (2,4-DM-4-Cn and 2,4-DM-2-Cn, resp.) was investigated. The change in the position of the alkyl substituent led to a variation in the thermal behavior, including the cold crystallization, which is a heat-storing phenomenon. In addition, a comprehensive study of the alkyl chain length revealed that 2,4-DM-4-Cn had better crystallinity and exhibited cold crystallization with short alkyl chains. The π-π, C-H···N, and C-H···π interactions stabilized the crystal structure of 2,4-DM-4-Cn. On the other hand, the polymorphism of 2,4-DM-2-Cn inhibited the formation of a uniform crystalline phase during cooling, which led to poor crystallinity. The only difference between the compounds, the position of the substituent, resulted in a clear variation in the cold crystallization and heat storage properties.

A method of para-selective borylation of fully twisted aromatic amides ArCONBoc₂ is described, yielding boronamides 4-pinBC₆H_nX_4-nCONBoc₂ (X = alkyl, alkoxy, aryl, halo, CN). The borylation proceeded via an unprecedented substrate-ligand distortion between the twisted aromatic amides and a newly designed ligand framework, 4,5-diaza-9H-fluorene (defa) that is different from the traditionally used ligand (dtbpy) for the C-H borylation reactions.

The identification of key transition states and intermediates using the DFT computations associated with the three regio-isomeric pathways revealed that the most efficient catalytic pathway with the defa ligand leads to the para borylation while in the case of bpy the borylation at the para and meta sites compete.
