Fish scale hydroxyapatite (FS-HAP) has been used as an efficient catalyst for the synthesis of 3-amino-1H-pyrazolo[1,2-b]phthalazine-2-carboxamide derivatives via the one-pot, three-component cyclocondensation reactions of aromatic aldehydes with cyanoacetamide and phthalhydrazide under solvent-free condition. FS-HAP has been characterized by FT-IR, XRD, SEM and EDS techniques. The synthesized compounds were evaluated for their in vitro antibacterial activity against gram-positive (Bacillus cereus, Bacillus aryabhattai, Bacillus megaterium, Staphylococcus aureus) and gram-negative (Serratia marcescens, Bacillus Pseudomonas putida, Escherichia coli, Enterobacter cloacae) bacteria. Tetracycline and erythromycin were used as standard antibiotics in this investigation. In the present protocol, we have achieved remarkable yields of the product in shorter reaction time and the catalyst was easily recovered and reused.

RAB1 5 is a lead antibacterial agent in which trimethoprim is linked to phthalazine moiety. Similarly, our strategy in this research depends on the interconnection between some sulfa drugs and certain phthalazin-1(2H)-one scaffolds in an attempt to enhance their antibacterial activity. This approach was achieved through the combination of 4-substituted phthalazin-1(2H)-ones 9a, b or 14a, b with sulfanilamide 1a, sulfathiazole 1b or sulfadiazine 1c through amide linkers 6a, b to produce the target compounds 10a-d and 15a-e, respectively. The antibacterial activity of the newly synthesized compounds showed that all tested compounds have antibacterial activity higher than that of their reference sulfa drugs 1a-c. Compound 10c represented the highest antibacterial activity against Gram-positive bacteria Streptococcus pneumonia and Staphylococcus aureus with MIC = 0.39 mu mol/mL. Moreover, compound 10d displayed excellent antibacterial activity against Gram-negative bacteria Escherichia coli and Salmonella Lyphimurium with MIC = 0.39 and 0.78 mu mol/mL, respectively.

A highly diastereo- and enantioselective, scalable Pd-catalyzed dynamic kinetic asymmetric Heck reaction of heterobiaryl sulfonates with electron-rich olefins is described. The coupling of 2,3-dihydrofuran or N-boc protected 2,3-dihydropyrrole with a variety of quinoline, quinazoline, phthalazine, and picoline derivatives takes place with simultaneous installation of central and axial chirality, reaching excellent diastereo- and enantiomeric excesses when in situ formed [Pd-0/DM-BINAP] was used as the catalyst, with loadings reduced down to 2 mol % in large scale reactions. The coupling of acyclic, electron-rich alkenes can also be performed using a [Pd-0/Josiphos ligand] to obtain axially chiral heterobiaryl alpha-substituted alkenes in high yields and enantioselectivities. Products from Boc-protected 2,3-dihydropyrrole can be easily transformed into N,N ligands or appealing axially chiral, bifunctional proline-type organocatalysts. Computational studies suggest that a beta-hydride elimination is the stereocontrolling step, in agreement with the observed stereochemical outcome of the reaction.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 1679-64-7, Name is 4-(Methoxycarbonyl)benzoic acid, molecular formula is C9H8O4, belongs to phthalazine compound. In a document, author is Paragas, Erickson M., introduce the new discover, Application In Synthesis of 4-(Methoxycarbonyl)benzoic acid.

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.
