| Abstract: | A search for poly(ADP-ribose) polymerase-1 inhibitors by virtual screening of a chemical compound database and a subsequent experimental verification of their activities have been done. It was shown that the most efficient method to predict inhibitory properties implies a combinatorial approach joining molecular docking capabilities with structural filtration. Among more than 300000 database chemicals 9 PARP1 inhibitors were revealed; the most active ones, namely: STK031481, STK056130, and STK265022,--displayed biological effect at a micro-molar concentration (IC50 = 2.0 microM, 1.0 microM and 2.6 microM, respectively). |
