抗肿瘤咪唑并[5,1- d ] -1,2,3,5-四嗪类化合物:在3位修饰的化合物克服了人胶质母细胞瘤细胞系的耐药性† ‡
摘要:
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。

The present invention provides methods for treating tumors of the brain by administering the compounds of the Formula A and particularly N-(3,4-dichloro-2-fluorophenyl)-7-([(3aR,6aS)-2-methyloctahydrocyclopenta[c]pyrrol-5-yl]methyl}oxy)-6-(methyloxy)quinazolin-4-amine, or a pharmaceutically acceptable salt thereof, to a subject in need of such treatment. In the methods of the invention, the compounds disclosed herein were surprisingly found to cross the blood brain barrier. The method of the present invention further relates to the treatment of cancers of any type potentially responding to EGFR, HER2, VEGFR2, or Src family kinase inhibitors and that are found in the brain.
The present invention provides combination compositions comprising Pt based compounds, including satraplatin, along with another chemotherapeutic agent such as temozolomide or lonafarnib. The combinations are useful for the prevention or treatment of cancer. Method of using the combinations to treat or prevent cancer are also provided
