A compound having a structure represented by the general formula (I):
(wherein n is 0 or 1;
R
1
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;
R
2
represents —(CH
2
)
p
—[O(CH
2
)
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);
R
3
represents a hydrogen atom, a C1-C6 alkyl group, a C7-C16 aralkyl group or a C6-C14 aryl group; and
R
4
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.
一种具有通式(I)所表示的结构的化合物:(其中n为0或1;R1表示氢原子(仅当n=0时)、卤素原子、C1-C6烷基、C1-C6卤代烷基、可选取代的氨基、可选取代的苯基、C1-C6烷硫基、C1-C6烷氧基、C1-C6卤代烷氧基或C7-C12芳基氧基;R2表示—(CH2)p—[O(CH2)q]r—X(其中X为卤素原子,p为1至6的整数,q为1至4的整数,r为0至4的整数);R3表示氢原子、C1-C6烷基、C7-C16芳基烷基或C6-C14芳基基团;以及R4表示氢原子或C1-C6烷基),或其药学上可接受的盐,在癌症中具有比FAMT更易积累、更亲和LAT1、更具选择性的优点,并且可以在临床设置中使用自动合成器标记,因此是一种非常多功能的PET成像剂。
