Discovery of Potent Poly(ADP-ribose) Polymerase-1 Inhibitors from the Modification of Indeno[1,2-c]isoquinolinone
摘要:
Novel indeno[1,2-c]isoquinolinone derivatives were synthesized and evaluated as inhibitors of the nuclear enzyme poly(ADP-ribose) polymerase-1 (PARP-1). These potent nonmutagenic PARP-1 inhibitors possess an additional five-membered ring between the B and C rings of 6(5H)-phenanthridinone. The most potent PARP-1 inhibitors were obtained from the substitution of the D ring at the C-9 position, in particular sulfonamide and N-acyl analogues (6 and 11). The 9-sulfonamide analogues 11a and 12a exhibited IC50 values of 1 and 10 nM, respectively.
