  Synthetic routes to 3-substituted imidazo[5,1-d]-1,2,3,5-tetrazines structurally related to temozolomide were explored. Interaction of 4-diazoimidazole-5-carboxamide with an isocyanate afforded high product yields when the isocyanate was available in acceptable purity. Alternatively, alkylation of the nor-temozolomide anion afforded high yields of new imidazotetrazines. Several compounds, evaluated

  探索了与替莫唑胺结构相关的3-取代的咪唑并[5,1- d ] -1,2,3,5-四嗪的合成途径。当以可接受的纯度获得异氰酸酯时，4-重氮咪唑-5-羧酰胺与异氰酸酯的相互作用提供了高产物收率。可选地，正-替唑啉酰亚胺阴离子的烷基化提供了高产率的新的咪唑并四嗪。针对含有匹配的MGMT±胶质瘤细胞系的一组化合物评估的几种化合物，无论MGMT的状态如何，均表现出相同的抑制活性。N3-炔丙基-咪唑并四嗪（10m）被优先作为替莫唑胺的替代品，后者能够绕过耐药机制。在Taq聚合酶测定法10m像替莫唑胺及其开环对应物MTIC一样，在三个和五个鸟嘌呤残基簇上的烷基化DNA；在哌啶裂解试验中检测到鸟嘌呤N-7位的共价修饰。化合物10m没有交联DNA，但是通过γ-H2AX检测证明诱导了双链断裂。炔丙基取代的咪唑三嗪（13g）显示出与10m相当的活性，表明新的咪唑四嗪的双环核开环可能是活性所必需的。
