  • On the role of singlet oxygen in the self-sensitized photo-oxygenation of bilirubin and its pyrromethenone models
    作者:G.L. Landen、Y.-T. Park、D.A. Lightner
    DOI:10.1016/s0040-4020(01)88703-2
    日期:1983.1
    undergo self-sensitized photo-oxygenation, as does bilirubin. The reaction products of 1 consist of methylethylmaleimide, kryptopyrrole aldehyde and its photo-oxygenation product and oxygenated dipyrroles. The same products are formed from 2, except xeronimide is found instead of methylethyl-maleimide. Kinetic studies indicate that singlet oxygen is not necessarily involved in the photo-oxygenation
    4-乙基-3-甲基-5-(4-乙基-3,5-二甲基吡咯基-2-亚甲基)-3-吡咯啉-2-酮(1),3,4-二乙基-5-(4-乙基- 3,5-二甲基吡咯基-2-亚甲基)-3-吡咯啉-2-酮(2)和黄胆红素酸(XBR)与胆红素一样经历自敏化的光氧合。1的反应产物由甲基乙基马来酰亚胺,k吡咯醛及其光氧化产物和氧化的二吡咯组成。由2形成相同的产物,不同之处在于找到了二氧酰亚胺,而不是甲基乙基-马来酰亚胺。动力学研究表明,单重态氧不一定参与光氧合反应。1和2的几何光异构化(Z →2 E),并且XBR的发展速度甚至比光敏化的氧合作用更快。
  • Total synthesis of symmetric bile pigments: Mesobilirubin-IVα, mesobilirubin-XIIIα and etiobilirubin-IVγ
    作者:Francesc R. Trull、Roger W. Franklin、David A. Lightner
    DOI:10.1002/jhet.5570240614
    日期:1987.11
    The unnatural bile pigments mesobilirubin-IVα, mesobilirubin-XIIIα and etiobilirubin-IVγ were synthesized following self-coupling of the pyrromethenones ψ-xanthobilirubic acid methyl ester, xanthobilirubic acid methyl ester and kryptopyrromethenone, respectively.
    吡咯烷酮ψ-黄胆红酸甲酯,黄胆红酸甲酯和k吡咯烷酮分别自偶联后,合成了非天然胆汁色素中胆红素-IVα,中胆红素-XIIIα和乙胆红素-IVγ。
  • Synthesis and acidity constants of 13CO2H-labelled dicarboxylic acids. pKas from 13C-NMR
    作者:Darren L. Holmes、David A. Lightner
    DOI:10.1016/0040-4020(96)00153-6
    日期:1996.4
    Simple dicarboxylic acids: adipic (1), succinic (2) and malonic (3); more complex linear tetrapyrroles with two propionic acid groups: mesobiliverdin-XIIIα (4) and mesobilirubin-XIIIα (5), and a rubin analog with a gem-dimethyl at C10 (6) were prepared with 99% 13C-enrichment in their CO2H groups. Their pKa values were determined from titration curves in water and in H2O-(CD3)2SO solutions: plots of
    简单的二元羧酸:己二酸(1),琥珀酸(2)和丙二酸(3);制备了具有两个丙酸基团的更复杂的线性四吡咯:mesobiliverdin-XIIIα(4)和mesobilirubin-XIIIα(5),以及在C 10(6)具有宝石-二甲基的红宝石类似物,其99 C 13 CO 2 H基团。由水和H 2 O-(CD 3)2 SO溶液中的滴定曲线确定其p K a值:羧基碳13图C-NMR化学位移随p H的变化而变化。在H 2 O中具有已知p K a的二酸1-3的滴定曲线用作测定四吡咯二酸4-6的p K a s的校准标准:p K a1 = 3.9,对于4,p K a2 = 5.3 ;p K a1 = 4.2,p K a2 = 4.9(5),p K a1 = 4.7,p K a2 = 5.7H 2 O中的6。
  • Strongly fluorescent dipyrrinones-substituent effects
    作者:Stefan E. Boiadjiev、David A. Lightner
    DOI:10.1002/jhet.5570410631
    日期:2004.11
    Bright yellow N,N'-carbonyl-bridged dipyrrinones (substituted 3H,5H-dipyrrolo[1,2-c:2′,1′-f]pyrimidine-3,5-diones) were synthesized by reaction of the parent dipyrrinone with carbonyldiimidazole. Their solutions in organic solvents fluoresced strongly, with fluorescent quantum yields (ϕF)0.32-0.92.

    日期:1991.11
    Thiolactam analogs of kryptopyrromethenone and xanthobilirubic acid methyl ester were prepared from the parent pyrromethenone using Lawesson's reagent and are shown to form dimeric association complexes through intermolecular hydrogen bonding.
