Nano-organocatalyzed one-pot four-component reactions for the synthesis of phthalazine-trione/dione derivatives have been devised for the first time from easily accessible starting materials under solvent-free conditions. This methodology showed very good substrate scope and high degree of tolerance for a variety of aldehydes (including aliphatic and heteroaromatic aldehydes) and active methylene compounds. Moreover, the catalyst can be easily separated from the reaction mixture because of its highly paramagnetic nature, by using an external magnet, and can be reused in five more consecutive runs without much decrease in catalytic activities. Other significant advantages of this method are shorter reaction time, good yield, simple work-up procedure, easy catalyst handling etc.

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. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

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.

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.

Quality Control of 4,4′-Methylenebis(2-methylaniline), We’ll be discussing some of the latest developments in chemical about CAS: 838-88-0, Name is 4,4′-Methylenebis(2-methylaniline), SMILES is NC1=CC=C(CC2=CC=C(C(C)=C2)N)C=C1C, belongs to phthalazine compound.

Solid-phase microextraction (SPME) coupled with thermal desorption-gas chromatography (TD-GC) has become a powerful analysis tool for volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) in water samples. However, water adsorption into polar microextraction phase is usually unavoidable during the extraction process, and the burst of large amounts of water vapour during thermal desorption will cause serious problems to GC separation and detectors. Pawliszyn’s group had demonstrated that the tens of micron-thick, defect-free polydimethylsiloxane (PDMS) coating could act as a perfect barrier for water adsorption and offer much better compatibility in complex matrices. However, the PDMS overcoat largely decreased the uptake rate of polar analytes into the inner sorbent. In order to quantify the effect of PDMS coating thickness on water adsorption amount and the extraction kinetics, ultrathin PDMS layer was used to coat the polar extraction phase with polyimide (PI) as a model in this work. It was surprising to find that the PDMS coating with the thickness less than one micron can decrease the water adsorption by 96%, while the extraction efficiency for polar analytes (phenolic compounds and nitroaromatic explosives) was decreased by less than 20% at the extraction time of 30 min. Moreover, the kinetic data showed that the thinner the PDMS coating was, the less the uptake rate of polar analytes into PI extraction phase decreased. Finally, polar poly (phthalazine ether sulfone ketone) (PPESK) extraction phase was also coated with ultrathin PDMS coating to verify the universality of the strategy. Generally, the water adsorption problem in polar SPME was overcome to a great extent, and the extraction efficiency of polar analytes was mainly preserved with this ultrathin PDMS coating, which could broaden the application of SPME in the environmental field.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Paragas, Erickson M., once mentioned the application of 88-44-8, Name is 4-Aminotoluene-3-sulfonic acid, molecular formula is C7H9NO3S, molecular weight is 187.2163, MDL number is MFCD00007908, category is phthalazine. Now introduce a scientific discovery about this category, Synthetic Route of 88-44-8.

Aldehyde oxidase (AOX) is a cytosolic enzyme responsible for the metabolism of some drugs and drug candidates. AOX catalyzes the oxidative hydroxylation of substrates including several aliphatic and aromatic aldehydes, and nitrogen-containing heterocyclic compounds. AOX is also reported to catalyze the reductive metabolism of nitro-compounds, N-oxides, sulfoxides, isoxazoles, isothiazoles, nitrite and hydroxamic acids. These reductive transformations are not well understood and are generally believed to only occur at low oxygen concentrations. In this study, we used 5-nitroquinoline (5NQ) as a substrate to further understand both the oxidative and the reductive transformations catalyzed by AOX. In vitro reaction of 5NQ with AOX under aerobic conditions generated the oxidized (2-oxo-5-nitroquinoline, 2-oxo-5NQ), the reduced (5-aminoquinoline, 5AQ) and the oxidized/reduced (2-oxo-5-aminoquinoline, 2-oxo-5AQ) metabolites. Interestingly, in human liver cytosol, co-incubation of 5NQ and known AOX oxidative substrates DACA and phthalazine significantly increased the yield of the reduced metabolite, while oxidized metabolites production decreased. These data indicate that 5NQ can be reduced at atmospheric oxygen concentrations and that the reductive transformation occurs at a second site that is kinetically distinct from the oxidative site.
