The discovery and synthesis of novel adenosine substituted 2, 3-dihydro-1H-isoindol-1-ones: potent inhibitors of poly (ADP-ribose) polymerase-1 (PARP-1)
A series of novel 4-(N-acyl)-2, 3-dihydro-1H-isoindol-1-ones have been prepared from methyl-3-nitro-2-methylbenzoate and linked through various spacers to the adenosine derivatives 11 and 12. We found that potent inhibition of poly (ADP-ribose) polymerase-1 (PARP-1) was achieved when isoindolinone was linked to adenosine by a spacer group of a specific length. Introduction of piperazine and succinyl linkers between the isoindolinone ...
