Vinylogous carbinolamine tumor inhibitors. 19. Synthesis and antineoplastic activity of bis[[[(alkylamino)carbonyl]oxy]methyl]-substituted 3-pyrrolines as prodrugs of tumor inhibitory pyrrolebis(carbamates)
摘要:
A series of bis[(carbamoyloxy)methyl]pyrrolines 2-4 were synthesized from either the appropriate alpha-silylated iminium salt, or an aziridine, or a 2H-azirine in a sequence involving 1,3-dipolar cycloaddition reactions. The antineoplastic activities of the pyrrolines were compared to the corresponding pyrroles. The C-2 gem-dimethyl-substituted pyrroline, 4, which cannot be converted to the pyrrole in vivo, was inactive. The activity of the 2-phenyl-substituted pyrrolines 3 was markedly dependent on the nature of the phenyl substituent, although the corresponding phenylpyrroles all showed comparable activity. The differences in the activities of the pyrrolines 3 may be due to the rate of metabolic conversion of the pyrroline to the pyrrole. Electron-withdrawing substituents on the phenyl ring appear to retard this process.

Disclosed are substituted aromatic N-heterocyclic compounds. The disclosed compounds typically exhibit kinase inhibition activity, for example, and inhibit Mnk1 kinase and/or Mnk2 kinase. The disclosed compounds may be used in pharmaceutical compositions and methods for treating diseases or disorders associated with Mnk1 kinase activity and/or Mnk2 kinase activity, such as cancers, diabetes, autism, and fragile X syndrome.

The synthesis of about forty new spirophosphoranes containing a PH bond offers examples of new cases of tautomeric equilibrium between the triand pentacoordinated forms as shown by: (a) recording the 31P NMR spectra between 20 and 150°, (b) using a chemical test which is specific of the PIII form. These results allowed us to discuss factors influencing the equilibrium PIII ⇌ PV.
