The halogenated xanthine derivatives and the precursors thereof for anti-cancer and anti-metastasis activity and the preparation method thereof are provided. The halogenated xanthine derivatives can further be radio-labeled with the radioactive halide group. The growth of human prostate carcinoma, tongue squamous cell carcinoma, colon adenocarcinoma and lung carcinoma can be inhibited and arrested in G

phase by KMUP-2Cl (7-[2-[4-(chlorophenyl)-piperazinyl]ethyl]-1,3-dimethyl-8-chloroxanthine). In addition, the growth of human prostate carcinoma LNCaP can be inhibited by KMUP-1 (7-[2-[4-(2-chlorobenzene)-piperazinyl]-ethyl]-1,3-dimethyl-xanthine), and the LNCaP prostate cancer xenograft growth in nude mice is effectively inhibited by the intraperitoneal injection and per oral administration of KMUP-1.
提供了用于抗癌和抗转移活性的卤代黄嘌呤衍生物及其前体,以及其制备方法。这些卤代黄嘌呤衍生物可以进一步与放射性卤素基团进行标记。通过KMUP-2Cl(7-[2-[4-(氯苯基)-哌嗪基]乙基]-1,3-二甲基-8-氯黄嘌呤),可以抑制和阻断人类前列腺癌、舌鳞状细胞癌、结肠腺癌和肺癌在G0/G1期的生长。此外,KMUP-1(7-[2-[4-(2-氯苯基)-哌嗪基]-乙基]-1,3-二甲基-黄嘌呤)可以抑制人类前列腺癌LNCaP的生长,通过腹腔注射和口服给药KMUP-1可以有效抑制裸鼠体内LNCaP前列腺癌异种移植瘤的生长。
