Novel amalgamation of phthalazine-quinolines as biofilm inhibitors: One-pot synthesis, biological evaluation and in silico ADME prediction with favorable metabolic fate

A facile and highly efficient one-pot synthesis of phthalazine-quinoline derivatives is reported via four component reaction of phthalic anhydride, hydrazine hydrate, 5,5-dimethyl 1,3 cyclohexanedione and various quinoline aldehydes using PrxCoFe(2-x)O(4) (x = 0.1) nanoparticles as a catalyst. The synthesized compounds have been evaluated for anti-biofilm activity against Pseudomonas aeruginosa and Candida albicans. The compounds 12a (IC50 = 30.0 mu M) and 12f (IC50 = 34.5 mu M) had shown promising anti-biofilm activity against P. aeruginosa and C. albicans, respectively, when compared with standards without affecting the growth of cells (and thus behave as anti-quorum sensing agents). Compounds 12a (MIC = 45.0 mu g/mL) and 12f (MIC = 57.5 mu g/mL) showed significant potent antimicrobial activity against P. aeruginosa and C. albicans, respectively. Thus, the active derivatives were not only potent biofilm inhibitors but also efficient antimicrobial agents. In silico ADME and metabolic site prediction studies were also held out to set an effective lead candidate for the future antimicrobial drug discovery initiatives. (C) 2016 Elsevier Ltd.

Phthalazine-trione as a blue-green light-emitting moiety: crystal structures, photoluminescence and theoretical calculations

Phthalazine (2,3-diazanaphthalene) and phthalhydrazide (2,3-dihydro-1,4-phthalazinedione) compounds are heterocycles with several biological properties. Most recently, analogous phthalazine-triones also emerged as drug candidates. Herein, we introduced a phthalazine-trione moiety as a promising fluorophore in the blue and green spectral regions. This desired optical property was rationalized based on their crystal structure and time-dependent density functional theory (TD-DFT) calculations. Under ultraviolet (UV) excitation (ca. 360 nm), two light emission maxima at ca. 460 nm and 480 nm were observed for ten phthalazine-triones, regardless of the substitution pattern. This conservation in the light-emitting property was rationalized by our time-dependent DFT calculations for the three phthalazine-triones whose crystal geometries were also determined in this study (4-chlorophenyl, 3-methoxyphenyl and 4-nitrophenyl derivatives) and for those available in literature (4-fluorophenyl and 4-bromophenyl derivatives). Electronic transitions with the largest oscillator strengths were near 360 nm and were in excellent agreement with the experimental excitation energy (UV-visible and photoluminescence spectra). Lifetime values of selected samples could also be determined, which were between 1.59 ns and 3.21 ns. In all compounds, the Frontier molecular orbitals involved in these excitations were distributed over the phthalazine-trione moiety and were not localized on the changeable substituent.

Synthesis, Characterization and Antimicrobial Activity of Bis(Phthalimido)Piperazine and its Derivatives: a New Class of Bioactive Molecules with Enhanced Safety and Efficacy

Piperazine rings are important heterocyclic targets in organic synthesis and are useful synthetic intermediates or intricate parts of biologically active molecules. In our efforts, a series of piperazine derivatives has been prepared discovering new classes of antimicrobial agents, including bis(phthalimido)piperazine, bis(3-aminopropyl) piperazine, 2,3-dihydro-phthalazine-1,4-dione, and bis(3,4-aminophenol)piperazine. The synthesized antimicrobial agents have been studied using various spectroscopic techniques. Furthermore, these compounds have been screened for their in vitro antimicrobial activity against selected bacterial and fungal strains. Three compounds exhibited mild to good antibacterial activity, but somewhat lower antifungal activity against tested microbial strains.

A novel chromogenic and fluorogenic chemosensor for detection of trace water in methanol

A novel receptor (E)-1-(phthalazine-4-yl)-2-(1-(pyridine-2-yl) ethylidene) hydrazine (3) was developed for the detection of trace water content present in methanol. Upon interaction of water molecule with receptor 3, there appears a significant color change from colorless to yellow green and the absorption band at 355 nm was shifted to 435 nm (i.e. bathochromic or red shift) due to selective encapsulation of water molecule at 1-(pthalazine-4-yl) hydrazine-NH and imine groups leading to tautomeric transformation in the ground state which is caused by an intramolecular proton transfer. Also, there was remarkable enhancement in fluorescence intensity of 3 in methanol upon addition of water. Thus the chemosensor 3 has been developed for chromogenic and fluorogenic investigation of water and the detection limit is 5 ppm in methanol. (C) 2015 Elsevier B.V. All rights reserved.
