PbO nanoparticles were explored as a highly efficient, simple, cheap, and recyclable catalyst for the fast synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by means of a one-pot three-component reaction of phthalhydrazide, aromatic aldehyde, and malononitrile under solvent-free conditions at 80 A degrees C. Furthermore, nanosized PbO was prepared by the two conventional methods of planetary ball milling and dispersion of commercial PbO in n-octane, and their catalytic performances were compared with the commercial bulk PbO. The prepared nano-PbO via ball milling was described by SEM, TEM, XRD, EDX, and FT-IR spectroscopy. The present protocol conveyed major proficiencies such as the use of a reasonable and readily available catalyst, simple work-up and purification of products by nonchromatographic strategy, low reaction times, and enhanced yields under relatively environmental benign conditions. The heterogeneous catalyst was appropriately recyclable and could be reused for several times without loss of activity.

Herein we report the design and synthesis of a new series of phthalazine derivatives as Topo II inhibitors and DNA intercalators. The synthesized compounds were in vitro evaluated for their cytotoxic activities against HepG-2, MCF-7 and HCT-116 cell lines. Additionally, Topo II inhibitory activity and DNA intercalating affinity were investigated for the most active compounds as a potential mechanism for the anticancer activity. Compounds 15h, 23c, 32a, 32b, and 33 exhibited the highest activities against Topo II with IC50, ranging from 5.44 to 8.90 mu M, while compounds 27 and 32a were found to be the most potent DNA binders at IC50, values of 36.02 and 48.30 mu M, respectively. Moreover, compound 32a induced apoptosis in HepG-2 cells and arrested the cell cycle at the G2/M phase. Besides, compound 32a showed Topo II poisoning effect at concentrations of 2.5 and 5 mu M, and Topo II catalytic inhibitory effect at a concentration of 10 mu M. In addition, compound 32b showed in vivo a significant tumor growth inhibition effect. Furthermore, molecular docking studies were carried out against DNA-Topo II complex and DNA to investigate the binding patterns of the designed compounds.

The reaction of 1-chloro-4-propargylaminophthalazine with various aryl halides catalyzed by Pd-Cu in the presence of potassium carbonate, as the base, in water leads to the one-pot formation of new derivatives of 3-aryl-substituted-6-chloroimidazo-[2,1-a]phthalazines in moderate-to-good yields. Their structures are confirmed by IR and NMR spectra as well as elemental analyses. All the compounds prepared are screened invitro for their anti-bacterial activities. The preliminary results indicate that some target compounds exhibit promising anti-bacterial potency.

Design and synthesis of novel PARP-1 inhibitors based on pyridopyridazinone scaffold

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.
