Structures and biological activity of cinnamoyl derivatives of coumarins and dehydroacetic acid and their boron difluoride complexes

Computer-assisted screening for Kohonen self-organizing maps in terms of the quantitative structure-activity relationship (QSAR) model revealed the high potential activity of cinnamoyl derivatives of coumarin and dehydroacetic acid and their boron difluoride complexes against a number of biological targets, including HIV-1 integrase. The pronounced inhibitory properties of dehydroacetic acid derivatives and their boron difluoride complexes against HIV-1 integrase were experimentally confirmed by in vitro testing of their antiviral activity with respect to HIV-infected cells. The data obtained suggests a correlation between the structure of the compounds studied and their biological activity.
