Formal propagation of (hetero)arylamine is achieved via a one-pot Buchwald–Hartwig C–N cross-coupling and nitro reduction sequence, enabling a rapid modular synthesis of diverse amino-di(hetero)arylamines from (hetero)arylamines and halogenated nitrobenzenes. Various functionalized aromatic amines with different electronic and steric environments can be efficiently prolongated to formally incorporate
Several aromaticamine compounds are urinary bladder carcinogens. Activated metabolites and DNA adducts of polycyclic aromaticamines, such as 4-aminobiphenyl, have been identified, whereas those of monocyclic aromaticamines, such as o-toluidine (o-Tol), o-anisidine (o-Ans), and aniline (Ani), have not been completely determined. We have recently reported that o-Tol and o-Ans are metabolically converted
几种芳香胺化合物是膀胱致癌物。多环芳胺的活化代谢物和 DNA 加合物,如 4-氨基联苯,已被鉴定,而单环芳胺,如邻甲苯胺 ( o -Tol)、邻茴香胺 ( o -Ans) 和苯胺 ( Ani),尚未完全确定。我们最近报道了o -Tol 和o -Ans 在体外和体内代谢转化为具有细胞毒性和致突变性的对半胺型二聚体,即 2-甲基-N 4 -(2-甲基苯基)苯-1,4-二胺 (MMBD) 和 2-甲氧基- N 4-(2-methoxyphenyl) benzo-1,4-diamine (MxMxBD),分别表明它们在膀胱癌发生中的作用。在这项研究中,我们发现当o -Tol 和o -Ans 与 S9 混合物一起孵育时,会形成 MMBD 和 MxMxBD 以及两种异构异二聚体 MMxBD 和 MxMBD。因此,o-Tol、o-Ans 和 Ani 中的任意两种(各10 mM)与 S9 混合物一起孵育长达

The present invention includes a method of preparing an inkjet ink imaged lithographic printing plate, comprising the steps of: imagewise applying onto a substrate coated with an inkjet ink reactive coating composition comprising a diazonium material, an inkjet ink to produce an imaged coated substrate wherein the inkjet ink imaged regions are oleophilic and more developer-insoluble than non-imaged regions; and contacting said imaged and non-imaged regions of said an imaged coated substrate and an aqueous developer to selectively remove said coating from said developer soluble non-imaged regions. The present invention also includes a lithographic printing plate, such as an inkjet ink imaged lithographic printing plate, which is prepared by the method of the present invention.
