    • The present invention relates to a new kind of heavy metal chelating agents and a preparation process and uses thereof. The said heavy metal chelating agents are expressed in &agr;-[D(+)glucose-1-yl-amino]-&bgr;3-mercapto-(S)-propanoic acid (abbreviated to NGP,I) and/or N,N′-di[D(+)glucose-1-yl]-L-cystine (abbreviated to NGCD,II). In the process of preparation, glucose and cysteine are reacted with a base, with a reducing agent, and the obtained products are acidified to give NGP,I, which can be used in and/or as drugs, health foods and food additives for accelerating the excretion of heavy metals including Pb, Cd, Hg, Al, Sb, As, etc. The structural feature of the compounds of the present invention is that they contain glucose and cysteirie in their molecules. Compared with the heavy metal-excreting drugs of prior art, the compounds of the present invention have four advantages, namely suitability for oral administration, high ability to accelerate the excretion of heavy metals, high selectivity and less toxicity.
    • 本发明涉及一种新型的重金属螯合剂及其制备方法和用途。 所述重金属螯合剂在α-[D(+)葡萄糖-1-基 - 氨基]-β-巯基 - (S) - 丙酸(缩写为NGP,I)和/或N, 二[D(+)葡萄糖-1-基] -L-胱氨酸(缩写为NGCD,II)。 在制备过程中,葡萄糖和半胱氨酸与碱反应,还原剂,将所得产物酸化,得到NGP,I,可用于和/或作为药物的保健食品和食品添加剂加速 重金属的排泄,包括Pb,Cd,Hg,Al,Sb,As等。本发明化合物的结构特征是它们在其分子中含有葡萄糖和半胱氨酸。 与现有技术的重金属排泄物相比,本发明的化合物具有四个优点,即口服适用性,加速重金属排泄能力高,选择性低,毒性小。
