N(3)-alkylation of 2-deoxo-2-methylthioalloxazine-5-oxides was carried out with various alkylating agents in the usual way. The antitumor activities against CCRF-HSB-2 and KB tumor cells have been investigated in vitro, and many compounds showed promising antitumor activities. Furthermore, AutoDock molecular docking into PTK (PDB: 1t46) has been done for lead optimization of the aforementioned compounds
通过对6-(N-烷基苯胺基)-2-甲基硫代嘧啶-4(3H)-进行亚硝化环化反应,然后制备各种新颖的10-烷基-2-脱氧-2-甲基硫黄素-5-氧化物及其2-烷基氨基衍生物。用不同的胺对2-甲硫基部分进行亲核取代,然后对2-甲硫基部分进行酸性水解,得到了相应的黄素衍生物。还分别通过Vilsmeier反应和通过对6-苯胺基-2-甲基硫代嘧啶-4(3H)-亚硝化来制备2-脱氧-2-甲基硫代5-脱氮杂恶嗪和2-脱氧-2-甲基硫代恶嗪-5-氧化物。然后,将它们用适当的胺进行亲核取代以产生相应的2-烷基氨基衍生物。用各种烷基化剂以常规方式进行2-脱氧-2-甲基硫代恶恶嗪-5-氧化物的区域特异性N(3)-烷基化。在体外已经研究了针对CCRF-HSB-2和KB肿瘤细胞的抗肿瘤活性,并且许多化合物显示出有希望的抗肿瘤活性。此外,已经完成了将AutoDock分子对接至PTK(PTB:1t46)的工作,以优化上述化合物作为潜在的PTK抑制剂的可能性。
