  A novel copper(I) sulfamate π-complex based on the 5-(allylthio)-1-(3,5-dimethylphenyl)-1H-tetrazole ligand: Alternating-current electrochemical crystallization, DFT calculations, structural and NLO properties studies

  摘要：

  Using the alternating-current electrochemical technique, the novel pi-complex [Cu-1(m-dmphast)NH2 SO3](1), based on the 5-(allylthio)-1-(3,5-dimethylphenyl)-1H-tetrazole (m-dmphast) ligand, was obtained and it was studied by single crystal X-ray diffraction as well as IR and UV-Vis spectroscopy. The structure 1 should be considered as the first known example of a metal sulfamate coordination compound with a tetrazole ligand. The copper(I) ion in 1 possesses a trigonal pyramidal environment, arranged from the N4 atom of the tetrazole core, the C=C bond from the S-allyl group of the same m-dmphast ligand and O and N atoms of the NH2SO3- anions. The sulfamate anion is coordinated to the two neighboring Cu(I) ions in a bridged mode, occupying a basal plane (through the N atom) and an apical (through an O atom) position of the two neighboring metal trigonal pyramids. The bicolor coherent photoinduced treatment by a nanosecond Nd:YAG laser at a wavelength of 1064 nm caused the occurrence of charge density acentricity, which in turn favours an occurrence of second harmonic generation described by third rank polar tensors, that are usually forbidden for centrosymmerical crystals.

  通过在氢氧化钠存在下将单乙醇胺硫酸氢盐与芳基异硫氰酸酯环化，可以合成3-（取代的苯基）咪唑烷-2-硫酮（SPIT）和相关化合物。用这些化合物检查了刺激从美国蟑螂美洲大i的胸神经线制备的腺苷酸环化酶的活性。具有2,6-二乙基苯基基团的SPIT（48）是唯一的完全激动剂，其他SPIT衍生物是部分激动剂。更大的酶活化似乎是由短链烷基而不是SPITs芳香环的2,6-位上的卤素取代引起的。在2,6-二取代的SPIT中，从甲基到乙基的链长增加导致酶激活增加。同时，在2中，从乙基到异丙基的链长进一步增加 6-二取代的SPIT导致酶活化降低。能量最小的章鱼胺和48的叠加显示出结构和构象相似，这说明48的Vmax值更高。在有效SPIT的咪唑烷环的C4或C5烷基化后，酶的活化作用明显降低。因此，在SPIT的苯环和N-末端的2-位和6-位的一定程度的蓬松度和疏水性对于活化腺苷酸环化酶是有利的。
