Staphylococcus aureus (Sa) is a serious concern due to increasing resistance to antibiotics. The bacterial dihydrofolate reductase enzyme is effectively inhibited by trimethoprim, a compound with antibacterial activity. Previously, we reported a trimethoprim derivative containing an acryloyl linker and a dihydophthalazine moiety demonstrating increased potency against S. aureus. We have expanded this series and assessed in vitro enzyme inhibition (K-i) and whole cell growth inhibition properties (MIC). Modifications were focused at a chiral carbon within the phthalazine heterocycle, as well as simultaneous modification at positions on the dihydrophthalazine. MIC values increased from 0.0626-0.5 mu g/mL into the 0.5-1 mu g/mL range when the edge positions were modified with either methyl or methoxy groups. Changes at the chiral carbon affected K-i measurements but with little impact on MIC values. Our structural data revealed accommodation of predominantly the S-enantiomer of the inhibitors within the folate-binding pocket. Longer modifications at the chiral carbon, such as p-methylbenzyl, protrude from the pocket into solvent and result in poorer K-i values, as do modifications with greater torsional freedom, such as 1-ethylpropyl. The most efficacious K-i was 0.7 +/- 0.3 nM, obtained with a cyclopropyl derivative containing dimethoxy modifications at the dihydrophthalazine edge. The co-crystal structure revealed an alternative placement of the phthalazine moiety into a shallow surface at the edge of the site that can accommodate either enantiomer of the inhibitor. The current design, therefore, highlights how to engineer specific placement of the inhibitor within this alternative pocket, which in turn maximizes the enzyme inhibitory properties of racemic mixtures.

New hydrophilic fluorescent selective ion sensor based on phenazine and phthalazine moieties, 1,1′-(phenazine-2,3-diyl)-bis(3-(1,4-dihydroxyphthalazin-6-yl)urea) (1), has been designed, synthesized and characterized. Interestingly, sensor 1 exhibits prominent turn-on and turn-off’ fluorogenic signaling at 580 nm towards Fe2+ & AcO- and Sr2+ & Cu2+, respectively. The fluorescence titration experiments shed light on the nature of the interaction between 1 and guest molecules (Fe2+, Sr2+, Cu2+ and AcO-), which divulge that 1 is flexible enough to orient itself according to the size of the guest molecule. Water mediated excited-state intramolecular proton transfer (ESIPT) and photo-induced electron transfer (PET) mechanisms are responsible for the dual behavior of 1, which binds with guest molecules in 1:1 stoichiometry, Based on the significant duplex fluorescence response of 1, a molecular logic gate keypad lock with sixteen on passwords for a storage system has been developed.

As aldehyde oxidase (AOX) plays an emerging role in drug metabolism, understanding its significance for drug-drug interactions (DDI) is important. Therefore, we tested 10 compounds for species-specific and substrate-dependent differences in the inhibitory effect of AOX activity using genetically engineered HEK293 cells over- expressing human AOX1, mouse AOX1 or mouse AOX3 The IC50 values of 10 potential inhibitors of the three AOX enzymes were determined using phthalazine and O-6-benzylguanine as substrates 17 beta-Estradiol, mena dione, norharmane and raloxifene exhibited marked differences in inhibitory effects between the human and mouse AOX isoforms when the phthalazine substrate was used. Some of the compounds tested exhibited substrate dependent differences m their inhibitory effects. Docking simulations with human AOX1 and mouse AOX3 were conducted for six representative inhibitors. The rank order of the minimum binding energy reflected the order of the corresponding IC50 values. We also evaluated the potential DDI between an AOX substrate (O-6-benzylguanine) and an inhibitor (hydralazine) using chimeric mice with humanized livers. Pretreatment of hydralazine increased the maximum plasma concentration (C-max) and the area under the plasma concentration- time curve (AUC(0-24)) of O-6-benzylguanine compared to single administration. Our in vitro data indicate species-specific and substrate-dependent differences in the inhibitory effects on AOX activity. Our in vivo data demon strate the existence of a DDI which may be of relevance in the clinical context.

An eco-friendly and efficient green protocol is developed for the synthesis of sixteen pyrazolo-phthalazine derivatives (5a-p) by using inexpensive biodegradable eggshell powder (ESP) as a heterogeneous catalyst. The four-component one-pot condensation reaction proceeded through Knoevenagel-Michael reaction of different chosen active methylene compounds, phthalic anhydride, and hydrazine hydride with various substituted aromatic aldehydes in the water at 60 degrees C, and furnished the high yields of products (93-98%) in rapid reaction time of 28 to 45 min. The material was characterized by different analytical techniques (SEM, TEM, XRD, BET, and FT-IR), and was composed of the high percentage of calcium oxides and carbonates, and less percentage of Na and Mg elements (based on EDX analysis).

New phthalazine-based vasodilators were synthesized through the chloroacylation of the starting compound 1-hydrazinophthalazine 4 to give the two key intermediates 5 and 7. These intermediates were used to alkylate various cyclic amines to furnish the final compounds 6a-h and 8a-h. Compounds were tested for their vasorelaxant activities against nor-adrenaline-induced spasm on thoracic rat aorta rings and compared to the reference drug, prazosin. Seven compounds showed higher activity than prazosin, especially compound 8d having an IC50 = 0.10 mM. Molecular modeling studies, including fitting of the synthesized compounds to a 3D-pharmacophore and their docking into optimized homology model as alpha(1)-AR antagonists showed high docking score and fit values. Most vasodilation activities of tested compounds are consistent with their molecular modeling results. (C) 2012 Elsevier Masson SAS. All rights reserved.

Hybrid molecules are composed of two pharmacophores with different biological activities. Here, we conjugated phthalazine moieties (antiangiogenetic pharmacophore) and bis(hydroxymethyl)pyrrole moieties (DNA cross-linking agent) to form a series of bis(hydroxymethyl)pyrrolo[2,1-a]phthalazine hybrids. These conjugates were cytotoxic to a variety of cancer cell lines by inducing DNA damage, arresting cell cycle progression at the G2/M phase, triggering apoptosis, and inhibiting vascular endothelial growth factor receptor 2 (VEGFR-2) in endothelial cells. Among them, compound 29d encapsulated in a liposomal formulation (e.g., 29dL) significantly suppressed the growth of small-cell lung cancer cell (H526) xenografts in mice. Based on immunohistochemical staining, the tumor xenografts in mice treated with 29dL showed time-dependent decreases in the intensity of CD31, a marker of blood vessels, whereas the intensity of gamma-H2AX, a marker of DNA damage, increased. The present data revealed that the conjugation of antiangiogenic and DNA-damaging agents can generate potential hybrid agents for cancer treatment.

Electrocatalytic multicomponent transformation of phthalhydrazide, aromatic aldehydes and malononitrile in n-propanol in an undivided cell in the presence of sodium bromide as an electrolyte leads to 1H-pyrazolo[1,2-b]phthalazine-5,10-diones in short reaction times (4-8 min) and high yields (85-98%) at room temperature.

We report herein the design and synthesis of a series of optimized phthalazine compounds as novel hedgehog signaling pathway inhibitors. The 4-methylamino-piperidine moiety of Taladegib was replaced by different four, five or six-membered azacycle or azaspirocycle building blocks. The in vitro Gliluciferase assay results demonstrate that the scaffold hopping in this region afforded significant influences on Hh pathway inhibition. Pyrrolidin-3-amine moiety was found to be the best linker between pharmacophores phthalazine and fluorine substituted benzoyl group. Meanwhile the optimization of 1-methyl-1H-pyrazol by different aromatic rings was also investigated and the SAR was described. Many new derivatives were found to show potent Hh signaling inhibitory activity with nanomolar IC50 values. Among these compounds, compound 23b showed the highest inhibitory potency with an IC50 value of 0.17 nM, which was 35-fold more potent than the lead compound Taladegib and 23-fold more potent than the marketed drug Vismodegib. The selected compounds 23a and 23b also possess potent antitumor activities against medulloblastoma cells proliferation in vitro. In vivo efficacy of 23b in a ptch(+/-)p53(-/-) mouse medulloblastoma allograft model also indicated encouraging results. (C) 2017 Elsevier Masson SAS. All rights reserved.
