Earlier investigators found that some N-nitrosated Amadori compounds, derived from glucose and amino acid condensation reactions, exhibit mutagenic properties and theorized that these potentially carcinogenic compounds might be formed in the human digestive system. To further investigate these compounds, N-nitrosated Amadori compounds [i.e., N-(1-deoxy-D-fructos-1-yl)-L-N-nitroso-glycine (5a), -threonine
早期的研究人员发现,某些源自葡萄糖和氨基酸缩合反应的N-亚硝化的Amadori化合物具有诱变特性,并据推测这些潜在的致癌化合物可能在人体消化系统中形成。为了进一步研究这些化合物,使用了N-亚硝化的Amadori化合物[即,N-(1-脱氧-D-果糖-1-基)-LN-亚硝基甘氨酸(5a),-苏氨酸(5b),-蛋氨酸(5c) ,-缬氨酸(5d),-苯丙氨酸(5e)和-色氨酸(5f)]是通过已知方法的修饰合成的。在雄性瑞士小鼠中对5a,5b,5c,5d,5e和5f进行的急性毒性测试分别产生以下最低的致命毒性极限:2000、2000、4000、3000、2000和6000 mg / kg,而最高耐受剂量分别为1750、1500、3000、1500和5000 mg / kg。5b在小鼠中的50%致死剂量(腹膜内)约为1777 mg / kg。该值至少是非处方药布洛芬的三倍(即小鼠腹膜内为495 mg /
