A series of pyrazolo[3,4-d]pyrimidine derivatives related to allopurinol has been synthesized and evaluated for its cytotoxicity against a panel of three cancer cell lines as well as its xanthine oxidase (XOD) inhibitory activities. Among them, compound 4 showed potent cytotoxicity with IC50 values of 25.5 and 35.2 μM against human hepatoma carcinoma cell lines, BEL-7402 and SMMC-7221, respectively
合成了一系列与别嘌呤醇有关的吡唑并[3,4-d]嘧啶衍生物,并评估了其对一组三种癌细胞系的细胞毒性以及黄嘌呤氧化酶(XOD)的抑制活性。其中,化合物4对人肝癌细胞株BEL-7402和SMMC-7221表现出强的细胞毒性,IC50值分别为25.5和35.2μM。4的抗癌活性与Tanespimycin(17-N-alalamino-17-demethoxy geldanamycin,17-AAG)相当,后者分别以12.4和9.85μM的IC50值抑制BEL-7402和SMMC-7221细胞的生长。 。但是,与别嘌呤醇(它也是XOD的强抑制剂)不同,化合物4是弱得多的XOD抑制剂,这表明别嘌呤醇衍生物的抗癌活性可能与XOD抑制无关。
