An easy and efficient synthesis of valylleucyl anilide (HValLeuNHPh) and labelled HVal(13C5,15N)LeuNHPh has been developed. Derivatization of these substances with oxirane, acrylonitrile, epichlorohydrin, glyceraldehyde and other aldehydes gives a series of reference substances and internal standards for the quantitative evaluation of human exposure to toxic electrophiles by quantitative determination
已开发出一种简单有效的缬氨酰苯胺 (HValLeuNHPh) 和标记的 HVal(13C5,15N)LeuNHPh 合成方法。这些物质与环氧乙烷、丙烯腈、环氧氯丙烷、甘油醛和其他醛类的衍生化,通过定量测定其血红蛋白加合物,为人类接触有毒亲电子试剂的定量评价提供了一系列参考物质和内标。NZN-Me-Val(13C5,15N)OH 与 HLeuNHPh 偶联,然后氢解得到 N-Me-Val(13C5,15N)LeuNHPh,用于量化甲基化剂的暴露量。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
