  [FR] COMPOSÉS D'IMIDAZOTÉTRAZINE ET TRAITEMENT DE CANCERS RÉSISTANTS AU TMZ

  摘要：

  Imidazotetrazines were designed to evade resistance byO6-methylguanine DNA methyltransferase (MGMT) while retaining suitable hydrolytic stability, allowing for effective prodrug activation and biodistribution. One compound, called TABZ, exhibits activity against cancer cells irrespective of MGMT expression and MMR status. TABZ has comparable blood-brain barrier penetrance and comparable hematological toxicity relative to TMZ, while also matching its maximum tolerated dose (MTD) in mice when dosed once-per-day over five days. The activity of TABZ is independent of the two principal mechanisms suppressing the effectiveness of TMZ, making it a promising new candidate for the treatment of GBM, especially those that are TMZ resistant.

  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
