Mono- or di-fluorinated analogues of flavone-8-acetic acid: synthesis and in vitro biological activity.
BACKGROUND Previously, the antitumour activity of some flavone-8-acetic acid (FAA) derivatives substituted with an acid function in position 2 of the benzene ring was evaluated. The most active compound resulted the one bearing a fluorine atom in position 7 of the flavone nucleus. In this paper, we evaluated new mono- or di-fluorinated FAA derivatives. MATERIALS AND METHODS The cytotoxicity t...
متن کاملSynthesis, Characterization and Crystal structure of Chiral Schiff base compound (E)-3, 4-Dimethoxy [(1-phenylethyl) iminomethyl] benzyne
The crystal structure of the title chiral Schiff base compound (E)-3,4-dimethoxy[(1-phenylethyl)iminomethyl]bezyne (1) was determined by single-crystal X-ray diffraction data. The title compound was further characterized by elemental analyses (CHN), FT-IR, 1H-NMR and UV-Vis spectroscopic techniques. It crystallizes in the monoclinic space group P21 with unit cell parameters: a = 19.0121 (2), b...
متن کاملSynthesis and antioxygenic activities of seabuckthorn flavone-3-ols and analogs.
A practical synthesis of polyhydroxy- and regiospecifically methylated flavone-3-ols which are components of commercial 'seabuckthorn flavone' has been achieved by modified Algar-Flynn-Oyamada method. Antioxidant activities of seabuckthorn extracts, isolated products and a number of flavone-3-ols have been determined. Structure-activity relationships have been discussed. Amongst the compounds t...
متن کامل[2,7-Dimethoxy-8-(4-methylbenzoyl)-1-naphthyl](4-methylphenyl)methanone
In the title compound, C(28)H(24)O(4), the two 4-methyl-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the dihedral angle between the two phenyl rings being 9.64 (7)°. The dihedral angles between the two phenyl rings and the naphthalene ring system are 71.82 (6) and 71.58 (6)°. In the crystal, inter-molecular C-H⋯O inter-actions between...
