A new class of radiation-protective compounds has been found in the bis(methylthio) and methylthio amino derivatives of 1-methylquinolinium- and 1-methylpyridinium-2-dithioacetic acids. The compounds gave good protection to mice vs. 1000-rad gamma-radiation in ip doses of 10 mg/kg or less, much lower than those required for the aminoalkyl thiols (approximately 150-600 mg/kg). The dithioacetic acid
在1-甲基喹啉鎓和1-甲基吡啶-2-二硫代乙酸的双(甲硫基)和甲硫基氨基衍生物中发现了一类新型的辐射防护化合物。与1000 rad或更少的ip剂量的1000 rad伽马射线相比,该化合物对小鼠具有良好的保护作用,远低于氨基烷基硫醇所需的剂量(约150-600 mg / kg)。由二硫化碳与喹诺定和甲基吡啶甲硫醇的碱催化反应制得二硫代乙酸两性离子,室温下与碘代甲烷反应生成双(甲硫基)衍生物。当双(甲硫基)衍生物与1摩尔当量的胺反应时,一个甲硫基部分的取代容易发生。
