Optimization of phthalazin-based aryl/heteroarylhydrazones to design new promising antileishmanicidal agents: synthesis and biological evaluation of 3-aryl-6-piperazin-1,2,4-triazolo[3,4-a]phthalazines

1-Monosubstituted and 1,4-substituted phthalazins based on aryl/heteroarylhydrazinyl have demonstrated attractive antileishmanial profiles against amastigote forms of theLeishmania braziliensisparasite. Further optimization of the mentioned acyclic scaffold motivated us to design a series of 3-aryl-1,2,4-triazolo[3,4-a]phthalazines, cyclic versions of the phthalazins based on aryl/heteroarylhydrazinyl, which have not been evaluated againstLeishmaniaparasites yet. In order to compare to phthalazine-based aryl/heteroarylhydrazones, five essential 3-aryl-6-piperazin-1,2,4-triazolo[3,4-a]phthalazines were efficiently prepared in excellent yields (73-83%) through a facile one-pot procedure from 4-chloro-1-phthalazinyl-arylhydrazonesviaC-H dehydrogenative cyclization using silver(i) salt. Fromin vitroantileismanial evaluation, compound2d, a nitro derivative, was identified as the most promising agent with a good anti-amastigote response (IC50= 9.37 mu M) and low relative toxicity against peritoneal macrophages (LD50= 123.93 mu M). A moderate response was found against clinical amastigote isolates ofL. braziliensis, although superior compared to the reference glucantime. A comparison with their phthalazin analogues based on aryl/heteroarylhydrazinyl gave evidence that the efficacy of each chemical system is determined by the nature of the functionalization next to the aryl moiety, which suggests that different mechanisms of action are involved for each chemical system. The cyclized form led to an enhancement of the antileismanial activity compared to the acyclic form, but the nitroderivatives seemed to be highly more toxic than the parent non-cyclized compounds. From the three compared phthalazine groups, 4-chloro-1-phthalazine-(5-nitrofuryl)hydrazinil with a nanomolar antileishmanial response was identified as a promising lead for further optimization, whereas compound2demerges as a prominent hit platform to prepare a group of derivatives based on phthalazine-1,2,4-triazolo bearing 3-nitro-phenyl at the 3-position.

Heteropolyacid-based ionic liquid [Simp](3)PW12O40 nanoparticle as a productive catalyst for the one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-triones under solvent-free conditions

A novel Keggin-type heteropolyacid-based ionic liquid [Simp](3)PW12O40 was developed via the reaction of the as synthesized ionic liquid 3-sulfonic acid 1-imidazolopyridinium hydrogen sulfate [Simp]HSO4 with an aqueous solution of H3PW12O40. Then, the formulated [Simp](3)PW12O40 was changed to the nano-form via solvothermal processing in tetralin at 220 degrees C. After that, the provided powdered solid nanomaterial was characterized by FTIR, H-1 NMR, XRD, SEM, EDX and TGA analyses. Then, the focused nanomaterial was handled as a productive and encouraging nanocatalyst for the establishment of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione attendants through one-pot, multi-component contraction of aldehydes, phthalhydrazide, and dimedone under solventless status and the generality and practical tolerance of this useful and environmentally benign method are illustrated. The simple work-up, smooth reaction conditions, good to excellent yields, and reasonably short reaction times are the particular benefits of this protocol. Besides, the new nano-powdered ionic liquid was a successful and modest catalyst that could definitely be recycled and reused several times without apparent decrease in its catalytic activity.

Surface-Enhanced Raman Spectroscopy-Based Approach for Ultrasensitive and Selective Detection of Hydrazine

A probe mediated SERS-based strategy is developed to selectively detect hydrazine with superb sensitivity. Ortho-phthaldialdehyde, a simple probe, reacts specifically with hydrazine to form phthalazine, a molecule that possesses a larger Raman cross section and better affinity toward the SERS substrate. We observed a limit of detection of 8.5 X 10(-11) M. Our method shows both qualitative and quantitative measurement of hydrazine with high sensitivity, low cost, and fast analysis time.

A new simple method for the preparation of PbO nanoparticles and implementation of an efficient and reusable catalytic system for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones

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.

Some Recent Approaches of Biologically Active Substituted Pyridazine and Phthalazine Drugs

Nitrogen atom containing heterocyclic compounds, pyridazines, pyridazinones and phthalazines are important structural feature of many biologically active compounds and show diverse pharmacological properties. Pyridazines and phthalazines hold considerable interest relative to the preparation of organic intermediates and physiologically active compounds. On the basis of literature, pyridazines, pyridazinone and phthalazines further focus our attention because of their easy fictionalization at various ring positions, which makes them attractive synthetic compounds for designing and development of the novel pyridazines and phthalazines drugs in future.

Synthesis of phthalazine derivative based organic nanoflakes in aqueous solvent as a potential nano-anticancer agent: A new approach in medical field

A simple phthalazine derivative 13-(4-bromophenyl)-3,3-dimethyl-3,4-dihydro-1H-indazolo[1,2-b] phthalazine-1,6,11(2H,13H)-trione (IDP) was synthesized by Knoevenagel condensation with Michael addition reaction. The present articles deals with preparation of highly fluorescent nanoparticles as prepared drug (IDP) by simple reprecipitation method using single aqueous solvent. The DLS measurement predicted the 150 nm size of a synthesized IDP NPs. Furthermore UV-Visible and fluorescence spectroscopy measurement showed a distinct peak for IDP NPs from their parent molecule. Scanning Electron Microscopy (SEM) microphotograph of air dried film of nanoparticles exhibited nanoflakes type and feathery morphology. The highly fluorescent nature of IDP NPs ultimately revealed in high quantum yield than IDP parent molecule. These fluorescent organic nanoflakes then further applied as anticancer agent. Interestingly it showed better activity than IDP molecules. Thus this is the first report to use organic nanoflakes as an anticancer agent, which may open new avenues in medical field’s and related sciences. (C) 2019 Elsevier B.V. All rights reserved.

Phosphoramidates as Transient Precursors of Nitrogen-Centered Radical Under Visible-Light Irradiation: Application to the Synthesis of Phthalazine Derivatives

Phosphoramidates are for the first time presented as efficient N-Centered Radical (NCR) precursors under visible-light irradiation. More precisely among this class of phosphorus-derived compounds, we studied the radical reactivity of phosphonohydrazones, under mild reaction conditions, which allowed the synthesis of a wide and diversified library of the scarcely reported phthalazine scaffold. Mechanistic investigations confirmed the formation of a NCR from these brand-new phosphonohydrazones (derivatived from phosphoramidates), which were further engaged in an intramolecular 6-exo-dig cyclization to provide phthalazines. Compared to other pre-activated moieties, the phosphoramidate group is self-immolative, thus enhancing its attractiveness for the C-N bond formation.
