Synthesis and cytotoxic activity of 1-alkoxy- and 1-amino-2-hydroxy-1,2-dihydroacronycine derivatives.
Sixteen new derivatives of the natural alkaloid acronycine, bearing 1-alkoxy or 1-amino and 2-hydroxy groups, were synthesized in order to clarify the role of the C-1 substitution. Studies on the cytotoxic activity of compounds 4-19 were carried out in vitro on L-1210 cells. Structure-activity relationships are discussed.

متن کاملSynthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone
An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...
متن کاملTheoretical prediction of spectroscopic constants of 1-alkoxy radicals
Spectroscopic constants for the conformers of the 1-alkoxy radicals were computed by ab initio and density functional methods. These parameters include ground and excited state rotational constants, harmonic frequencies, and Ã− X̃ and B̃ − X̃ excitation energies. Elements of the electronic spin-molecular rotation tensor have also been predicted for the ground electronic state utilizing a simple tr...
متن کاملAlkyl vs. alkoxy chains on ionic liquid cations.
The crystal structures and thermal behavior of the 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexa-fluorophosphate salts are compared with the analogous 1-butyl-2,3-dimethylimidazolium salts to examine the influence of the ether oxygen on salt thermal properties for a typical constituent cation used in the preparation of ionic liquids.
