Synthesis, in vitro metabolic studies, and antitumour activity of methyl analogues of ifosfamide
摘要:
Synthesis of 2-chloro-1,1-dimethylethyl and 2-chloro-2,2-dimethylethyl analogues of ifosfamide was performed via aziridine intermediate. In vitro metabolic activation showed that both compounds are metabolised at a rate similar to the parent drug. However, their anticancer activity against L1210 leukaemia in mice was lower as compared with ifosfamide. The reduction of antitumour efficiency of examined analogues is probably caused by a lower ability to cross-link DNA by their final, active metabolites.

that leads to five- or six-membered metallacyclic intermediates. Analogous reactions that occur through four-membered metallacycles are rare. We report a challenging palladium-catalyzedoxidation of primary C-H bonds β to nitrogen in an imine of an aliphatic amine, a process that occurs through a four-membered palladacyclc intermediate. The success of the reaction relies on the identification, by a study
