A compound having a structure represented by the general formula (I):
(wherein n is 0 or 1;
R1 represents a hydrogen atom (only if n = 0), a halogen atom, a C1-C6 alkyl group, a C1-C6 haloalkyl group, an optionally substituted amino group, an optionally substituted phenyl group, a C1-C6 alkylthio group, a C1-C6 alkoxy group, a C1-C6 haloalkoxy group or a C7-C12 aralkyloxy group;
R2 represents - (CH2)p-[O(CH2)q]r-X (wherein X is a halogen atom, p is an integer of 1 to 6, q is an integer of 1 to 4, and r is an integer of 0 to 4);
R3 represents a hydrogen atom, a C1-C6 alkyl group, a C7-C16 aralkyl group or a C6-C14 aryl group; and
R4 represents a hydrogen atom or a C1-C6 alkyl group), or
a pharmaceutically acceptable salt thereof excels FAMT in terms of the tendency to accumulate intensively in cancer, the affinity for LAT1 and the selectivity for cancer, and can be labeled using an automated synthesizer in clinical settings, and therefore is useful as a highly versatile PET imaging agent.
具有通式 (I) 所代表结构的化合物:
(其中 n 为 0 或 1;
R1 代表氢原子(仅当 n = 0 时)、卤素原子、C1-C6 烷基、C1-C6 卤代烷基、任选取代的氨基、任选取代的苯基、C1-C6 烷硫基、C1-C6 烷氧基、C1-C6 卤代烷氧基或 C7-C12 芳氧基;
R2 代表-(CH2)p-[O(CH2)q]r-X(其中 X 为卤素原子,p 为 1-6 的整数,q 为 1-4 的整数,r 为 0-4 的整数);
R3 代表氢原子、C1-C6 烷基、C7-C16 芳基或 C6-C14 芳基;以及
R4 代表氢原子或 C1-C6 烷基),或
或其药学上可接受的盐,其在癌症中的聚集倾向、对 LAT1 的亲和力和对癌症的选择性方面均优于 FAMT,并可在临床中使用自动合成器进行标记,因此可用作用途广泛的 PET 成像剂。
