New enamine derivatives of lapachol and biological activity.
A convenient synthesis of the new enamine derivatives 2-(4-morpholinyl)-3-(3-methyl-2-butenyl)-1,4-naphthalenedione, 2-(1-piperidinyl)-3-(3-methyl-2-butenyl)-1,4-naphtalenedione and 2-(1-pyrrolidinyl)-3-(3-methyl-2-butenyl)-1,4-naphthalenedione was carried out from natural 2-hydroxy-3-(3-methyl-2-butenyl)-1,4-naphthalenedione (lapachol) and morpholine, piperidine and pyrrolidine. The structures...
متن کاملSynthesis,Characterization, Biological Evaluation and anti corrosion activity of some new bis-piperidone Derivatives
Aseries of piperidine derivatives was synthesis by the reaction between substituted benzaldhyde ,pentanone-3,and ammonium acetate by refluxining for 1-2 hr in ethanol and the derivatives refluxed with (4,4'-Diaminodiphenyl sulphone) yielded bispiperidine ,the structures of the synthesized compounds were confirmed by spectroscopy analysis , The reported compounds were screened for their antibact...

متن کامل[New coumarin derivatives with expected biological activity].
A number of novel 3-bromo-4-methyl-7-methoxy-8-amino substituted coumarins and 2-substituted 7-bromo-6-methyl-8H-pyrano-benzimidazoles, benzoxazoles and/or benzoxazine-8-ones were synthesized for the purpose of pharmacological evaluation. Some representative compounds showed antitumor activity in vitro on Ehrlich ascites carcinoma in the preliminary testing.
متن کاملSynthesis of Some New Bisindole Derivatives and Their Biological Activity
Substituted 1,4-diaza-1,3-butadienes with 2 equivalents of 1,4-naphthoquinone in presence of ethanol or benzene produce corresponding substituted bisindoletetrones via criss-cross cycloaddition reaction. The chemical structure was confirmed by elemental and spectral analysis. Biological activity against some micro-organisms was tested.
