Synthesis and biological evaluation of platinum(II) complexes containing (1R,2R)-N1-alkyl-1,2-diaminocyclohexane and D-(+)-camphorate ligands
摘要:
Five platinum(II) complexes with N-monoalkyl derivatives of 1R,2R-diaminocyclohexane as ligands and D-(+)-camphorate anion as leaving group have been synthesized and characterized by elemental analysis, IR, H-1 NMR, ESI-MS, and HRMS spectra. All complexes were evaluated for their in vitro cytotoxicity against four human tumor cell lines and most of them showed promising cytotoxic activity, especially compounds 3 and 4 with branched alkyl substituent at one of nitrogen atoms. Preliminary mechanism study by flow cytometry and agarose gel electrophoresis was also carried out in comparison with cisplatin and oxaliplatin. (C) 2012 Elsevier B. V. All rights reserved.
介绍了一系列新型有机催化剂的设计、制备和研究。催化剂的设计灵感来自于 DNA 核碱基发展精确和明确的氢键的能力。我们已经表明,这种现象可用于创建一种有用的有机催化剂,该催化剂显示出类似于常见有机底物的识别模式。基于鸟嘌呤结构的选定双功能催化剂已被证明可催化 1,3-二羰基化合物与各种硝基烯烃的共轭加成,从而以良好的产率和对映选择性提供产品。

Design and Development of Bioinspired Guanine-Based Organic Catalyst for Asymmetric Catalysis
Design, preparation, and studies of a family of new organiccatalysts are presented. The design of the catalysts is inspired by the ability of DNA nucleobases to develop precise and explicit hydrogen bonds. We have shown that this phenomenon can be used to create a useful organiccatalyst that demonstrates a recognition pattern similar to those of common organic substrates. A selected bifunctional
