a series of 3-hydroxypyridin-4-one derivatives (hpos) were synthesized and their partition coefficient values (k part ) were determined. the cytotoxic effects of these iron chelators against hela cancer cells were also evaluated. the ic 50 of hpos was determined using mtt assay. among these ligands, compound 4e (k part =5.02) with an ic 50 of 30 µm and 4f (k part =0.1) with an ic 50 of 700 µm s...
In the title E isomer of the racemic compound, C37H32F2N2O2, the pyridinone ring adopts a twisted half-chair conformation with the N atom deviating by -0.355 (3) Å and with the methyl-ene C atom next to octa-hydro-indolizine moiety deviating by 0.415 (3) Å from the mean plane defined by other four atoms. In the octa-hydro-indolizine system, the pyrrolidine ring exhibits an envelope conformation...
A new method for the solid-phase synthesis of enantiomerically enriched highly substituted ring-fused 2-pyridinones 13 has been developed. The synthesis mediates introduction of substituents at two positions in the 2-pyridinone ring in a diverse manner and is suitable for parallel synthesis. (19)F NMR spectroscopy was used as a tool to monitor each of the five steps in the reaction sequence. Th...
The asymmetric unit of the title compound, C(19)H(18)N(2)O(3), comprises a whole organic dipyridinone mol-ecule plus a water mol-ecule of crystallization. The planes of the pyridinone rings are approximately perpendicular with the plane of the central aromatic ring [dihedral angles = 80.68 (8) and 83.65 (8)°]. The C-O bond of the hy-droxy group subtends an angle of 31.71 (10)° with the plane th...
Multinuclear platinum anticancer complexes are a proven option to overcome resistance of established anticancer compounds. Transferring this concept to ruthenium complexes led to the synthesis of dinuclear Ru(II)-arene compounds containing a bis(pyridinone)alkane ligand linker. A pronounced influence of the spacer length on the in vitro anticancer activity was found, which is correlated to the ...
