3-Pyrroline N-oxide bis(carbamate) tumor inhibitors as analogs of indicine N-oxide
摘要:
The 2,3-bis[[(N-methylcarbamoyl)oxy]methyl]-3-pyrroline 1-oxide 5 was synthesized and tested in the murine P388 lymphocytic leukemia model. The compound showed significant reproducible activity and was more potent than indicine N-oxide. 1-Methyl-2-phenyl-3,4-bis[[(N-2- propylcarbamoyl)oxy]methyl]-3-pyrroline N-oxide (6) was less active than 5, and the 5,5-dimethyl analogue of 6, the pyrroline N-oxide 7, was inactive. The N-oxide 7 cannot be converted to a pyrrole in vivo because of the gem-dimethyl substitution at C-5.
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.
