Design and synthesis of new anticancer scaffolds; pyrazolo[3,4-d][1,2,3]triazine derivatives, is a promising solution to overcome drug resistance problem. A series of (E)-2-cyano-N-(aryl)-3-methylthio-3-(substituted-amino)acrylamides 3a-e was synthesized and transformed to the 3-aminopyrazole derivatives 4a-e which were then transformed to the target pyrazolotriazinones 6a-e. All compounds were evaluated
新型抗癌支架的设计与合成;吡唑并[3,4- d ] [1,2,3]三嗪衍生物是克服耐药性问题的一种有前途的解决方案。合成了一系列(E)-2-氰基-N-(芳基)-3-甲硫基-3-(取代的氨基)丙烯酰胺3a-e,并将其转化为3-氨基吡唑衍生物4a-e,然后将其转化为3-氨基吡唑衍生物。目标吡唑并三嗪酮6a-e。评估了所有化合物对三种不同癌细胞系Huh-7,Panc-1和CCRF的抗癌活性。化合物3a,3c,6a和6c对Huh-7细胞系显示出优异的抗癌活性(IC 50:4.93-8.84μM对阿霉素5.43μM )。同样,化合物6a和6d对Panc-1细胞显示出优异的活性(IC 50:9.91μM和4.93μM,而阿霉素为6.90μM)。进行了Caspase-Glo 3/7测定,结果表明目标化合物的促凋亡活性可能是由于刺激了胱天蛋白酶3/7。6c处理Huh-7细胞的微阵列实验进行搜索以寻找其他分
