values of 1.77, 1.94 and 2.87 μM, respectively. The synthesized compounds were then evaluated for their inhibitory activity to mammalian dihydrofolate reductase. Compound 22 was depicted as the most active compound for the inhibition of dihydrofolate reductase with IC50 value of 2.0 nM. DNA binding studies were also revealed strong interacting properties of triazine derivatives towards calf thymus-DNA
已经设计和合成了一系列被4-氟苯胺取代的三嗪-苯并咪唑。这些化合物进一步被不同的伯胺和仲胺取代。新合成的化合物的结构通过1 H,13 C NMR,质谱确定,对于化合物18,通过单晶X射线衍射分析确定。以一剂和五剂浓度水平针对60种人类肿瘤细胞系评估了新合成的化合物。化合物7,8和22已被发现是最活跃的抗肿瘤剂与GI 50值分别为1.77、1.94和2.87μM。然后评估合成的化合物对哺乳动物二氢叶酸还原酶的抑制活性。化合物22被描述为抑制二氢叶酸还原酶的最具活性的化合物,IC 50值为2.0 nM。DNA结合研究还揭示了三嗪衍生物与小牛胸腺DNA的强相互作用特性。
