  • .beta.-Substituted cysteines as sequestering agents for ethanol-derived acetaldehyde in vivo
    作者:Herbert T. Nagasawa、James A. Elberling、Jeanette C. Roberts
    DOI:10.1021/jm00391a018
    日期:1987.8
    of beta-mono- and beta,beta-disubstituted cysteines were evaluated in rats as sequestering agents for metabolically generated acetaldehyde (AcH) during the oxidation of ethanol in vivo and compared against D-(-)-penicillamine. Both threo- (5) and erythro-beta-phenyl-DL-cysteine (6) reduced ethanol-derived blood AcH by ca. 40% and 60%, respectively, whereas the corresponding beta-methyl-DL-cysteines (3
    在大鼠中评估了一系列β-单-和β,β-二取代的半胱酸作为螯合剂,用于体内乙醇氧化过程中代谢生成的乙醛(AcH),并与D-(-)-青霉胺进行了比较。threo-(5)和erythro-beta-phenyl-DL-cysteine(6)均能降低乙醇衍生的血液AcH量。分别为40%和60%,而相应的β-甲基-DL-半胱氨酸(3和4)和α-取代的α-甲基-DL-半胱氨酸(8)无效。但是,β,β-四亚甲基-DL-半胱氨酸(7)在体内隔离AcH方面与D-(-)-青霉胺一样有效,可将乙醇后的血液AcH降低至最大值的20%。因此,这种活性需要在半胱酸上进行大体积的β取代或更好的β,β二取代。14C标签2(RS),5,

  • Synthesis of dual 14C-labeled (+)-calanolide A, a naturally occurring anti-HIV agent
    作者:Subbareddy Gaddam、Albert Khilevich、Crist Filer、John D. Rizzo、Jeremey Giltner、Michael T. Flavin、Ze-Qi Xu
    DOI:10.1002/(sici)1099-1344(199711)39:11<901::aid-jlcr39>3.0.co;2-h
    日期:1997.11
    [10,18-C-14]-(+)-Calanolide A [(+)-6] was synthesized in four steps from chromeno-coumarin 2. A Ti-mediated and reaction of 2 with [1,2-C-14]acetaldehyde stereoselectively produced the desired syn diastereomer (+/-)-3, with carbons at the 13 and 14 positions being C-14-labeled. Intermediate (+)-3 was isolated by lipase-catalyzed kinetic resolution and cyclized under Mitsunobu conditions to afford (+)-trans-2,3-dimethyl chroman-4-one, (+)-5. Luche reduction on (+)-5 in EtOH/THF at -78 degrees C led to the formation of dual C-14-labeled (+)-6 with a specific activity of 49.25 mCi/mmol. The overall radiochemical yield was 4.3% based on the starting C-14-acetaldehyde.
