Acid-base behaviour and binding to double stranded DNA/RNA of benzo[g]phthalazine-based ligands

The affinity and the binding mode of two benzo[g]phthalazine compounds, functionalized with one or two 2-(imidazole-4-yl)-ethylamine groups, to DNA and RNA models have been evaluated by means of UV-Vis, fluorescence and circular dichroism (CD) spectroscopies in combination with viscometry and molecular dynamics. Both organic molecules bind strongly to all nucleic acid models via the intercalation mode in the duplex structure, especially compound 1. Intriguingly, 1 exhibits different emission responses depending on the base composition of duplex DNA/RNAs, which points out the possibility of using it as a base selective nucleic acid probe. Moreover, the acid-base behaviour of both compounds has been studied by pH-metric titrations and UV-Vis and emission fluorescence techniques to investigate the unexplored basicity of this type of compound. 1 behaves as a triprotic base whilst 2 is a diprotic base with the protonation of the benzo[g]phthalazine moiety occurring in the physiological pH range.

Synthesis of some pyridazine derivatives as antioxidants and antimicrobial agents

Purpose: To prepare some pyridazine derivatives as antioxidant and antimicrobial agents. Methods: The coupling of aryl diazonium salts with diethyl 2-cyano-3-methylglutaconate afforded pyridazine-5-carbonitrile derivatives (3a-e). The methyl function in the pyridazine derivatives (3a-e) reacted with cinnamonitriles to yield phthalazine derivatives (6a-h). Imino-pyridazine derivatives (9a-h) were obtained by reacting 2-aminoprop-1-ene-1,1,3-tricarbonitrile along with aryl diazonium salts (1a-h). Structure elucidation was done by spectral analysis. The 1,1-diphenyl-2-picryl hydrazyl (DPPH) technique was employed to assess antioxidant effect, while evaluation of antimicrobial activity was carried out by serial dilution technique. Results: Compounds, 6f (IC50 = 12.68 mu g/mL; p < 0.05), 6a (IC50 = 14.23 mu g/mL; p < 0.05), and 3c (IC50 = 14.34 mu g/mL; p < 0.05) displayed good antioxidant activity compared to ascorbic acid (IC50 = 12.45 mu g/mL; p < 0.05). Based on the zone of inhibition, compound 6c (p < 0.05) displayed higher activity than ofloxacin (p < 0.05) against E. coli. Conclusion: The presence of an oxo group and carboxylate group plays an important role in the antioxidant activity of these compounds. Compounds 6a, 6f, and 3c can potentially serve as lead compounds for the development of promising antioxidants. I hope this article can help some friends in scientific research.

A new efficient domino approach for the synthesis of pyrazolyl-phthalazine-diones. Antiradical activity of novel phenolic products

Pyrazolyl-phthalazine-dione derivatives (PPDs) were synthetized in the ionic liquid catalyzed one-pot multicomponent reaction of acetylacetone, 2,3-dihydrophthalazine-1,4-dione, and different aldehydes in moderate to good yields. Six new PPDs were obtained, and the crystal structure of 2-acetyl-1-(4-fluorophenyl)- 3-methyl-1H-pyrazolo[1,2-b] phthalazine-5,10-dione (PPD-4) was determined. The most interesting structural features of the novel PPD-4 is the formation of a rather short intermolecular distance between the F atom of one molecule and the midpoint of the neighbouring six-membered heterocyclic ring. This interaction arranges all molecules into parallel supramolecular chains. UV-Vis spectra of all PPDs were acquired and compared to the simulated ones obtained with TD-DFT. All synthetized compounds were subjected to evaluation of their in vitro antioxidative activity using a stable DPPH radical. It was shown that PPD-7, with a catechol motive, is the most active antioxidant, while PPD-9, with two neighbouring methoxy groups to the phenolic OH, exerted a somewhat lower, but significant antioxidative potential. The results of DFT thermodynamical study are in agreement with experimental findings that PPD-7 and PPD-9 should be considered as powerful radical scavengers. In addition, the obtained theoretical results (bond dissociation and proton abstraction energies) specify SPLET as a prevailing radical scavenging mechanism in polar solvents, and HAT in solvents with lower polarity. On the other hand, the obtained reaction enthalpies for inactivation of free radicals suggest competition between HAT and SPLET mechanisms, except in the case of the (OH)-O-center dot radical in polar solvents, where HAT is labeled as prefered.

Synthesis and Dynamic Behavior of an Anthyridine-Ligated Ruthenium Complex

A ruthenium complex containing a 1,9,10-anthyridine derivative, [Ru(L)(bpy)(2)](PF6)(2) ( [1] (PF6)(2); L = 1,13,14-triazadibenz[a,j]anthracene, bpy = 2,2′-bipyridyl), was synthesized. X-ray crystal structural analysis of [1](PF6)2 showed that L is coordinated to the Ru center as a bidentate ligand. When [1](PF6)(2) was dissolved in acetonitrile, a new complex incorporating one acetonitrile molecule, [Ru(L)(CH3CN)(bpy)(2)](PF6)(2) ([2] (PF6)(2)), was formed. X-ray crystallographic data revealed that, in [2](PF6)(2), L is coordinated to the Ru center in a monodentate fashion. The coordinated L in [2](PF6)(2) shows a unique haptotropic rearrangement in an acetonitrile solution.
