Molecules, Vol. 19, Pages 18676-18689: Design and Synthesis of Isosteviol Triazole Conjugates for Cancer Therapy

14.11.2014 | Khaybullin, Ravil N.; Zhang, Mei ; Fu, Junjie ; Liang, Xiao ; Li, Tammy ; Katritzky, Alan R.; Okunieff, Paul ; Qi, Xin, Molecules, 2014

One of the keys for successfully developing drugs against the broad spectrum of cancer cell types is structural diversity. In the current study, we focused on a family of isosteviol derivatives as potential novel antitumor agents. Isosteviol is a tetracyclic diterpenoid obtained by acid ...

Biocompatible Infinite‐Coordination‐Polymer Nanoparticle–Nucleic‐Acid Conjugates for Antisense Gene Regulation

13.11.2014 | Colin M. Calabrese, Timothy J. Merkel, William E. Briley, Pratik S. Randeria, Suguna P. Narayan, Jessica L. Rouge, D ..., Angewandte Chemie International Edition, 2014

Abstract Herein, we report the synthesis of DNA‐functionalized infinite‐coordination‐polymer (ICP) nanoparticles as biocompatible gene‐regulation agents. ICP nanoparticles were synthesized from ferric nitrate and a ditopic 3‐hydroxy‐4‐pyridinone (HOPO) ligand bearing a pendant azide. Addition ...

Sequential Control over Thiol Click Chemistry by a Reversibly Photoactivated Thiol Mechanism of Spirothiopyran

12.11.2014 | Zhenzhen Liu, Tao Liu, Qiuning Lin, Chunyan Bao, Linyong Zhu, Angewandte Chemie International Edition, 2014

Abstract A novel photocontrolled thiol click chemistry based on spirothiopyran and maleimide is reported. Upon irradiation with λ=365 nm light, the spirothiopyran can isomerize to the open merocyanine form, a thiophenolate group, which can rapidly react with maleimide. The unreacted MC will ...

Formation of the first derivatives of praseodymium‐containing metallofullerenes via regioselective carbene addition to Pr@C2v(9)‐C82

12.11.2014 | Qin Zhou, Hui Li, Yan Wang, Yongfu Lian, physica status solidi (a), 2014

The first derivatives of praseodymium‐containing metallofullerenes are formed through regioselective cycloaddition of adamantylidene carbene to Pr@C2v(9)‐C82, and two isomers out of the 35 possible monoadducts are successfully isolated. Optical adsorption and electrical chemistry ...

Simple Plate-Based, Parallel Synthesis of Disulfide Fragments using the CuAAC Click Reaction

12.11.2014 | David M. Turner; Christopher T. M. B. Tom; Adam R. Renslo, Journal of Combinatorial Chemistry, 2014

Disulfide exchange screening is a site-directed approach to fragment-based lead discovery that requires a bespoke library of disulfide-containing fragments. Previously, we described a simple one-pot, two-step synthesis of disulfide fragments from amine- or acid-bearing starting materials. Here, ...

Conformational Transformations of Sulfur‐Containing Rings: 2‐Methyltetrahydrothiophene Gas‐Phase Structures

06.11.2014 | Vinh Van, Christina Dindic, Ha Vinh Lam Nguyen, Wolfgang Stahl, ChemPhysChem, 2014

Abstract Stable conformations of five‐member rings with the prototype cyclopentane are well‐known to exist as twist or envelope structures and are of general interest in chemistry. Here, we report on the conformational analysis of the sulfur‐containing ring 2‐methyltetrahydrothiophene studied ...
