Pathogenic fungi are one of the main causes of hospital-related infections. Since conventional antifungals have become less effective because of the increasing fungal resistance to the standard drugs, the need for new agents is becoming urgent. Herein we report a synthesis of a series of novel N-[imino-(1-oxo-(1H)-phthalazin-2-yl) methyl]benzenesulfonamide derivatives with in vitro activity against yeast-like fungi isolated from the oral cavity and respiratory tract of patients with candidiasis. These compounds were synthesized by the one-step or two-step reactions of 1-(2-alkylthiobenzensulfonyl)-2aminoguanidines with the appropriate ortho-carbonyl benzoic acids. The biological study revealed that new derivatives have shown significant growth-inhibitory activity, superior or comparable, than those of the reference drug fluconazole. The most promising activities were observed against Candida albicans, with inhibition at least 1-3 (12.5%-37.5%) of the eight tested strains at the low MIC level of <= 6.2-25 mu g/mL.

Multicomponent reactions between phthalazine, alkyl isocyanides, and 1,1-dicyanoalkenes in acetonitrile-water mixture produced high yields of substituted pyrrolo[2,1-a]phthalazines, which were converted upon treatment with 10% hydrochloric acid to pyrrolo[2,1-a]-phthalazines unsubstituted at position 1. As a result, a range of new pyrrolo[2,1-a]phthalazine derivatives have been synthesized by this one-pot approach.

Aldehyde oxidase (AOX) is a xanthine oxidase (XO)-related enzyme with emerging importance due to its role in the metabolism of drugs and xenobiotics. We report the first crystal structures of human AOX1, substrate free (2.6-angstrom resolution) and in complex with the substrate phthalazine and the inhibitor thioridazine (2.7-angstrom resolution). Analysis of the protein active site combined with steady-state kinetic studies highlight the unique features, including binding and substrate orientation at the active site, that characterize human AOX1 as an important drug-metabolizing enzyme. Structural analysis of the complex with the noncompetitive inhibitor thioridazine revealed a new, unexpected and fully occupied inhibitor-binding site that is structurally conserved among mammalian AOXs and XO. The new structural insights into the catalytic and inhibition mechanisms of human AOX that we now report will be of great value for the rational analysis of clinical drug interactions involving inhibition of AOX1 and for the prediction and design of AOX-stable putative drugs.

Herein we report a protocol for visible-light-induced copper-catalyzed decarboxylative coupling reactions between N-heteroarenes and redox-active esters. Various N-hydroxyphthalimide esters reacted with isoquinoline, quinoline, pyridine, pyrimidine, quinazoline, phthalazine, phenanthridine, and pyridazine to give the corresponding products in modest to excellent yields. The reactions proceed under mild conditions and have a broad scope and high functional group tolerance. Mechanistic studies revealed that the catalytic behavior of Cu-I photocatalyst generated in situ was consistent with that of preformed [Cu(dmp)(xantphos)]BF4.

Despite the great potential for applications spanning, from military night-vision displays and information-secured devices to civilian medical diagnostics and phototherapy, the development of highly efficient, stable, and low-cost near-infrared (NIR) emitting lumophores is still a formidable challenge. Herein, we report two novel NIR-emitting homoleptic facial Ir(III) complexes based on extended pi-conjugated benzo[g]phthalazine ligands, namely, tris[1,4-di(thiophen-2-yl)benzo(g]phthalazine] (Ir(dtbpa)(3), 1) and tris[1-(2,4-bis(trifluoromethyl)pheny1)-4-(thiophen-2-y1)-benzo[g]phthalazine] iridium(III) (Ir(Ftbpa)(3), 2). Actually, these two ligarids not only enable simple one-pot synthesis of homoleptic Ir(III) complexes without any catalyst under mild conditions, but also contribute to intense NIR-emission with high photoluminescence quantum yield up to 5.2% at 824 nm for 1 and 17.3% at 765 nm for 2 respectively. Single-crystal structure of 1 demonstrates desired facial form with short Ir-N and Ir-C bonds because of strong coordination and small steric hindrance of those highly conjugated C<^>N=N ligands. Importantly, the incorporation Of CF3 groups in 2 further leads to high thermal stability and a good ability to sublime, thus resulting in ultrapurity for highly efficient NIR-organic light-emitting diodes (NIR-OLEDs) with a high maximum external quantum efficiency of 4.5% at 760 run and small efficiency roll-off remaining of 3.5% at 100 mA. cm(-2), values which rank with those of the most efficient NIR-OLEDs with small roll-off and peak emission over 750 nm. Notably, the content percentages of the noble metal in these two complexes, (similar to 10% Ir) are markedly lower by about two-thirds than that of typical green-emitting tris(2-phenylpyridine)iridium (similar to 30% Ir). The findings may provide a new strategy to develop robust NIR emitters and achieve high efficiency, small roll-off, and low cost simultaneously in NIR-OLEDs for practical applications.

In this paper, C-N bond formation between 2,3-dihydrophthalazine-1(4H),4-dione (phthalhydrazide) and alpha,beta-unsaturated esters was investigated and a new series of phthalazine derivatives was synthesized using an efficient and simple method under solvent-free conditions. An aza-Michael addition of phthalhydrazide to both acrylic and fumaric esters led to N-monosubstituted phthalhydrazides (as mono-Michael adduct) in the presence of tetrabutylammonium bromide as a high polar media, and 1,4-diaza-bicyclo[2,2,2] octane as an available organic base. In this reaction, the N1,N2-bis-Michael adduct was not observed at all. Also, reactions were performed at 90 degrees C and yields of products were good to excellent.
