Previous studies have identified that indole-oxidases are present in P. putida, whose major ligands are heterocyclic substrates and have an interesting affinity when the substrate is indole. 19005-93-7, formula is C9H7NO, Name is 1H-Indole-2-carbaldehyde. These enzymes oxidize the ring so the substrate turns into Indigo. Recommanded Product: 1H-Indole-2-carbaldehyde.
Zhang, Xinyu;Wang, Dan;Shen, Hao;Wang, Shuxian;Zhou, Yunbing;Lei, Yunxiang;Gao, Wenxia;Liu, Miaochang;Huang, Xiaobo;Wu, Huayue research published 《 3,6-Diamino-7,8-dihydroisoquinoline-4-carbonitrile derivatives: unexpected facile synthesis, full-color-tunable solid-state emissions and mechanofluorochromic activities》, the research content is summarized as follows. A series of novel 3,6-diamino-7,8-dihydroisoquinoline-4-carbonitrile (DDIC) derivatives I [R = Bn, R1 = Me; R2 = Ph, 4-FC6H4, 2-thienyl, etc.; RR1 = (CH2)4, (CH2)5, (CH2)2CH(CH3)(CH2)2, etc.] were prepared from dicyanomethylene-4H-pyran derivatives and secondary amines by a mechanism of ring-opening and sequential ring-closing reactions. This reaction had the advantages of readily available materials, simple operations, mild reaction conditions, a broad substrate scope and good yields. The DDIC derivatives displayed solid-state fluorescence with the emission wavelengths covering the whole visible light range and the solid-state emissions were demonstrated to be ascribed to the twisted mol. conformations and loose stacking modes by crystal structural anal. Among the compounds, 9aa exhibited a bathochromic mechanofluorochromic (MFC) phenomenon from blue to cyan due to increased mol. conjugation upon grinding, whereas 3aj and 3ka exhibited hypsochromic MFC activities with the color changing from orange to green and red to orange, resp., because of decreased mol. conjugation, revealing that full-color-tunable emissions could also be realized by mechanofluorochromism. Furthermore, MFC-active mols. could be used in the field of encryption of important image or text information. Addnl., 3ka was demonstrated to emit single-mol. white fluorescence in organic solvents through the regulation of the concentration The unexpected discovery of the DDIC derivatives provided a new possibility for the design and synthesis of novel isoquinoline-based fluorescent materials with excellent performance in the solid state.
