The present invention relates to a chelating agent of the general formula: (I), wherein m is 0 or 1; X is NR4 or S; Y is SR5, NHR5 or P(R5)2; R1 and R3 are the same or different and are selected from H, alkyl or aryl; R2 is H, COOH, NHR6 or (CH2)nCOOR6; R4 is H, alkyl, aryl, (CH2)nCOOR6 or (CH2)nOR6; R5 is H, alkyl, aryl, (CH2)nCOOR6 or (CH2)nOR6, R6 is H, alkyl or aryl; n is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10; and when R1=R3=CH3, R2, R4 and R5 are not all three H. The invention further relates to a method and kit for the preparation of radiolabeled biomolecules while using the chelating agent.
本发明涉及一种螯合剂的普遍公式:(I),其中m为0或1;X为NR4或S;Y为SR5,NHR5或P(R5)2;R1和R3相同或不同,选自H,烷基或芳基;R2为H,COOH,NHR6或(CH2)nCOOR6;R4为H,烷基,芳基,(CH2)nCOOR6或(CH2)nOR6;R5为H,烷基,芳基,(CH2)nCOOR6或(CH2)nOR6,R6为H,烷基或芳基;n为1、2、3、4、5、6、7、8、9或10;当R1=R3=CH3时,R2、R4和R5不全为H。本发明还涉及一种利用该螯合剂制备放射标记生物分子的方法和试剂盒。
