AB  - A simple and convenient synthesis of tautomeric (6 or 2)-hydroxy-4-methyl-(2 or 6)-oxo-1-(substituted phenyl)-(1,2 or 1,6)-dihydropyridine-3-carbonitriles from ethyl acetoacetate and 2-cyano-N-(substituted phenyl)ethanamides using microwave-assisted chemistry is presented. The structure of the obtained product was confirmed by the use of FT-IR, NMR, UV, and MS techniques. The presence of tautomeric forms (6-hydroxy-4-methyl-2-oxo-1-(substituted phenyl)-1,2-dihydropyridine-3-carbonitrile and 2-hydroxy-4-methyl-6-oxo-1-(substituted phenyl)-1,6-dihydropyridine-3-carbonitrile) and the state of equilibrium of the obtained product in DMSO-d (6) was studied by H-1 and C-13 NMR spectroscopy, as well as B3LYP/6-311++G(d,p) and GIAO/WP04/aug-cc-pVDZ theoretical calculations.

AB  - From the Montenegrin spurge Euphorbia dendroides, seven new diterpenoids [jatrophanes (1-6) and a tigliane (7)] were isolated and their structures elucidated by spectroscopic techniques. The biological activity of the new compounds was studied against four human cancer cell lines. The most effective jatrophane-type compound (2) and its structurally closely related derivative (1) were evaluated for their interactions with paclitaxel and doxorubicin using a multidrug-resistant cancer cell line. Both compounds exerted a strong reversal potential resulting from inhibition of P-glycoprotein transport.

AB  - A series of some new pyridone arylazo dyes was synthesized from the corresponding diazonium salts and 3-cyano-4,6-diphenyl-2-pyridone using the classical reaction for the synthesis of the azo compounds. The structures of these dyes were confirmed by UV-Vis, FT-IR and 1H-NMR spectroscopic techniques. The solvatochromism of the dyes was evaluated with respect to visible absorption properties in various solvents. The effects of solvent dipolarity/polarizability and solvent/solute hydrogen bonding interactions were analyzed by means of the linear solvation energy relationship concept proposed by Kamlet and Taft. The 2-pyridone/2-hydroxypiridine tautomeric equilibration was found to depend on the substituents as well as on the solvents.
AB  - Serija novih piridonskih arilazo boja je sintetisana reakcijom odgovarajućih diazonijum soli i 3-cijano-4,6-difenil-2-piridona primenom klasične sinteze azo jedinjenja. Struktura sintetisanih boja je potvrđena na osnovu podataka dobijenih iz UV, FT-IR i 1H-NMR spektara. Solvatohromna svojstva boja su procenjena u odnosu na njihovu apsorpciju u vidljivom delu spektra u različitim rastvračima. Efekti rastvarača, dipolarnost/polarizabilnost i vodonične interakcije rastvarač/rastvorak, su analizirane primenom linearne korelacije solvatohromnih efekata predložene od strane Kamlet-a i Taft-a. Tautomerna ravnoteža 2-piridon/2-hidroksipiridin zavisi kako od efekata supstituenta tako i od uticaja rastvarača.
