1. First evidence of KPC-producing ST258 Klebsiella pneumoniae in river water.

Author

Jelić, M., Hrenović, J., Dekić, S., Goić-Barišić, I., and Tambić Andrašević, A.

Abstract

This paper reports the first case of Klebsiella pneumoniae carbapenemase (KPC)-2-producing K. pneumoniae in river water in Croatia. In total, four KPC-2-producing K. pneumoniae isolates were analysed. All isolates shared a similar genetic background, belonging to ST258. Isolates displayed uniform, multi-drug-resistant profiles susceptible to colistin. blaSHV-1, aac(3')-II, aac(6')-Ib and aph(3')-Ia genes were detected in all isolates. In all isolates, the blaKPC-2 gene was localized on a single non-conjugative IncFII plasmid that varied in size (∼140, ∼230, ∼225 and ∼220 kb). K. pneumoniae was viable in river water for up to 50 days, confirming its ability to survive and disseminate in the environment. [ABSTRACT FROM AUTHOR]

2. A detailed analysis of volatile constituents of Aquilegia pancicii Degen, a Serbian steno-endemic species

Author

Radulović, N., Dekić, M., Zlatković, B., Dekić, S., Dekić, V., and Palić, R.

Abstract

Chemical composition of the essential oil of Aquilegia pancicii Degen endemic to Serbia is reported. Essential oil obtained by hydrodistillation from the aerial parts was analyzed by GC and GC/MS. The major constituents were hexadecanoic acid (24.3 %) and hexahydrofarnesyl acetone (14.1 %), among 130 identified compounds, representing 90.3 % of the total essential oil. The oil was marked by the presence of 69 fatty acid derivatives and low content of terpenoids representing 60.4 % and 7.8 % of the oil, respectively.

3. Synthesis of new condensed and cyclized coumarin derivatives

Author

Dekić, S., Dekić, V., Dekić, B., and Dekić, M.

Abstract

Condensation of 4-chloro-2-oxo-2H-chromene-3-carbonitrile with selected heteroarylamines in acetonitrile containing a catalytic amount of triethylamine, followed by intramolecular cyclization, gave the new coumarin derivatives with yields ranging from 43 % to 78 %. The novel compounds were subjected to acid hydrolysis giving the corresponding oxo derivatives in 66–70 % yield. The structural assignments of the synthesized compounds were based on elemental, IR, 1H and 13C NMR analyses.
