摘要

A new class of highly functionalized tetrahydroisoquinolines with a quaternary carbon stereocenter was synthesized starting from an easily accessible l-tartaric acid. Nine strains of bacteria ( Staphylococcus aureus , Streptococcus pyogene s, Streptococcus mutans , Streptococcus salivarius , Bacillus subtilis , Enterococcus faecalis , Moraxella catarrhalis , Escherichia coli , Campylobacter jejuni ) were used for the determination of minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of synthesized compounds. The influence of analyzed compounds on viability and induction of apoptosis in human skin fibroblasts was determined. A majority of the synthesized compounds showed the strongest antibacterial properties toward some gram-negative bacteria (M. catarrhalis and C. jejuni ) with a high level of selectivity. High antibacterial compounds have bactericidal activity ratio MBC/MIC =4. Our studies also proved that the novel compounds do not possess cytotoxic and proapoptotic potential in normal cells.
