The present invention relates to novel substituted pyrrolo- and pyrazolopyridazinones, as well as pharmaceutical compositions containing at least one of these substituted pyrrolo- and pyrazolo- pyridazinones together with at least one pharmaceutically acceptable carrier, excipient and/or diluent. Said novel substituted pyrrolo- and pyrazolo- pyridazinones are binding to the prenyl binding pocket of PDEδ and therefore, are useful for the prophylaxis and treatment of cancer by inhibition of the binding of PDEδ to K-Ras and of Ras signaling in cells.

(η3-1- and 2-Trimethylsiloxyallyl)Fe(CO)2NO complexes were prepared by the reaction of the corresponding siloxyallylic halides with Bu4N[Fe(CO)3NO]. These complexes reacted with both of carbon nucleophiles and carbon electrophiles preferentially at the less hindered sites of the allylic ligands. In these reactions, (η3-1-trimethylsiloxyallyl)Fe(CO)2NO complexes served as synthetically equivalent synthons

The K‐Ras GTPase is a major target in anticancer drug discovery. However, direct interference with signaling by K‐Ras has not led to clinically useful drugs yet. Correct localization and signaling by farnesylated K‐Ras is regulated by the prenylbinding protein PDEδ. Interfering with binding of PDEδ to K‐Ras by means of small molecules provides a novel opportunity to suppress oncogenic signaling. Here

application of a Paal–Knorr synthesis. In this manuscript, we investigate the chemoselectivity and diastereoselectivity of furansynthesisfrom α-halo ketones and β-dicarbonyl compounds, by carrying out the separation and characterization of the intermediates involved in the reaction. Additionally, a one-pot Feist–Benaryfuransynthesisfrom α-halo ketones and β-dicarbonyl compounds without any base or solvent
