1676-73-9, Name is H-Glu(OBzl)-OH, molecular formula is C12H15NO4, belongs to phthalazine compound, is a common compound. In a patnet, author is Elmasry, Ghada F., once mentioned the new application about 1676-73-9, Quality Control of H-Glu(OBzl)-OH.
Various pyridopyridazinone derivatives were designed as Poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors. The pyridopyridazinone scaffold was used as an isostere of the phthalazine nucleus of the lead compound Olaparib in addition to some modifications in the tail part of the molecule. Preliminary biological evaluation indicated that most compounds possessed inhibitory potencies comparable to Olaparib in nanomolar level. The best PARP-1 inhibitory activity was observed for compound 8a with (IC50 = 36 nM) compared to Olaparib as a reference drug (IC50 = 34 nM). Molecular modeling simulation revealed that, the designed compounds docked well into PARP-1 active site and their complexes are stabilized by three key hydrogen bond interactions with both Gly863 and Ser904 as well as other favorable pi-pi and hydrogen-pi stacking interactions with Tyr907 and Tyr896, respectively. Computational ADME study predicted that the target compounds 8a and 8e have proper pharmacokinetic and drug-likeness properties. These outcomes afford a new structural framework for the design of novel inhibitors for PARP-1.
