    on the indazole building block have been investigated referring to molecular modeling hypotheses and thanks to the in vitro biological evaluation of N1- and N2-methyl and ethyl-4-substituted indazoles on nNOS. Secondly, we attempted to confirm the importance of the substitution in position 4 or 7 by a hydrogen bond acceptor group thanks to the synthesis and the in vitro biological evaluation of a new
    考虑到我们团队先前在文献中报道的4-和7-硝基和卤代吲哚类化合物作为nNOS抑制剂的效力,最近在本文中进行了一项多学科研究,以阐明它们在酶活性位点的结合方式。首先,参考分子模型假设并通过对N 1-和N 2的体外生物学评估,研究了吲唑构件上的氮固定点。nNOS上的-甲基和乙基-4-取代的吲唑。其次,由于新的类似的4-取代的衍生物4-氰基吲唑的合成和体外生物学评估,我们试图确认氢键受体基团在4或7位取代的重要性。最后,与先前的假说相反,吲哚在位置1处的NH功能是关键的固定点,因此本研究表明氮在位置2上起着至关重要的作用。

    New N-alkyl-nitroindazolylacetonitriles were efficiently obtained via vicarious nucleophilic substitution of N-methyl-nitroindazoles with 4-chlorophenoxyacetonitrile. All compounds were fully characterized by NMR and mass spectroscopy techniques and the structures of some of them were additionally confirmed by X-ray diffraction analysis data. Tautomeric switching was observed in this series of nit
    通过用4-氯苯氧基乙腈将N-甲基-硝基吲唑类化合物进行亲核取代,可以有效地获得新的N-烷基-硝基吲哚基乙腈。所有化合物均已通过NMR和质谱技术进行了充分表征,其中一些化合物的结构还通过X射线衍射分析数据得到了证实。加入碱性阴离子后,在该系列硝基吲哚基乙腈中观察到互变异构转换,然后进行UV-Vis分光光度法和1 H-NMR滴定。阴离子官能团诱导的互变异构物质的形成得到密度泛函理论计算的支持。

In this manner, the amino, methylamino, dimethylamino and dimethylamino substituents are introduced in 3,4,5 or 7-position. The irradiation in the presence of ethanol gives ethoxyindazoles in only four cases. Two demethylation reactions have been observed: the first one concerns

    as precursors were developed and labeled with carbon-11 and fluorine-18, respectively. For this purpose, a protecting group strategy essentially had to be generated to prevent unwanted methylation and to enable the introduction of fluorine-18. Further, a convenient radiolabeling strategy using [11C]methyl iodide was established which afforded the isotopically labeled radiotracer in 30–35% RCY (d.c.)
