Facile synthesis of multi-functional 1,3,4-thiadiazine derivatives bearing phthalazine, pyridazine, and pyrido-pyridazine moieties

A series of novel, multifunctional 1,3,4-thiadiazine derivatives bearing phthalazines, pyridazines and pyrido-pyridazines (9-13) have been synthesized via the multicomponent reaction of (3-(2-bromo-2-[2-chloropyrimidin-4-yl]acetyl)-2-chlorophenyl)-2,6-dichloro benzene-sulfonamide with thiocarbohydrazide and various anhydrides. The reactions were performed by refluxing the components in mixed ethanol/acetic acid to afford the corresponding products in good to excellent yields. All the synthesized compounds were characterized by analytical and spectral studies. The developed method features short reaction time, simple work-up without chromatographic separation, and a broad range of substrate applicability.

Nanostructured gamma-Fe2O3 @Starch-n-Butyl SO3H as New Recyclable Magnetic Catalyst for Promoting Multi-Component Reactions

Butane-1-soltunic acid modified starch-coated gamma-Fe2O3 magnetic nanoparticles (gamma-Fe2O3 @starchn-butyl SO3H] was easily prepared through a ring opening reaction of 1,4-butane sultone with nanomagnetic gamma-Fe2O3 @starch. After structural studies, using FT-IR, SEM, XRD, TGA, TEM, EDX, VSM and also pH analysis the efficiency of this reagent in the preparation of tetrahydrobenzimidazo[2,1-b] quinazolin-1(2H)-ones and 2H-indazolo[2,1-b]phthalazine-triones was studied. Operational simpleness, high yields, short reaction times, wide applicability and simple recyclability of the catalyst employing an external magnet are the most important advantages of this methodology.

A convenient, environmentally friendly and efficient procedure for the synthesis 3,4-dihydro-1H-indazolo[1,2-b]phthalazine-1,6,11(2H,13H)-trione derivatives has been developed via multi-component and one-pot reactions of various aldehydes with cyclic 1,3-diketones and phthalhydrazide 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). In simple and mild reaction conditions, the use of HFIP is explored as an easy workup and a green catalyst for the one-pot three-component synthesis of 3,4-dihydro-1H-indazolo[1,2-b]phthalazine-1,6,11(2H, 13H)-triones. Thus, this practical method is developed as a notable medium for these derivatives via a multicomponent reaction.

Imidazole-containing phthalazine derivatives inhibit Fe-SOD performance in Leishmania species and are active in vitro against visceral and mucosal leishmaniasis

The in vitro leishmanicidal activity of a series of imidazole-containing phthalazine derivatives 1-4 was tested on Leishmania infantum, Leishmania braziliensis and Leishmania donovani parasites, and their cytotoxicity on J774.2 macrophage cells was also measured. All compounds tested showed selectivity indexes higher than that of the reference drug glucantime for the three Leishmania species, and the less bulky monoalkylamino substituted derivatives 2 and 4 were clearly more effective than their bisalkylamino substituted counterparts 1 and 3. Both infection rate measures and ultrastructural alterations studies confirmed that 2 and 4 were highly leishmanicidal and induced extensive parasite cell damage. Modifications to the excretion products of parasites treated with 2 and 4 were also consistent with substantial cytoplasmic alterations. On the other hand, the most active compounds 2 and 4 were potent inhibitors of iron superoxide dismutase enzyme (Fe-SOD) in the three species considered, whereas their impact on human CuZn-SOD was low. Molecular modelling suggests that 2 and 4 could deactivate Fe-SOD due to a sterically favoured enhanced ability to interact with the H-bonding net that supports the antioxidant features of the enzyme.

The six-membered ring of the indazolone moiety has an envelope conformation, with the central methylene C atom as the flap. In the crystal, molecules are linked via C-H center dot center dot center dot O hydrogen bonds, forming slabs parallel to the bc plane. The slabs are linked via C-H center dot center dot center dot pi and pi-pi interactions [the shortest intercentroid distance involving rings of pyrazolophthalazine moieties is 3.6430 (8) angstrom], forming a three-dimensional structure.

Anion conductive poly(tetraphenyl phthalazine ether sulfone) containing tetra quaternary ammonium hydroxide for alkaline fuel cell application

The poly(tetraphenyl ether ketone sulfone)s (PTPEKSs) were synthesized from 1,2-bis(4-fluorobenzoyl)-3,4,5,6-tetraphenyl benzene (BFBTPB) and bis(4-fluorophenyl) sulfone with bis(4-hydroxydiphenyl) sulfone in sulfolane. The synthesis of poly(tetraphenyl phthalazine ether sulfone)s (PTPPESs) was carried out via an intramolecular ring-closure reaction of dibenzoylbenzene moiety with hydrazine monohydrate. The PTPPES-QAHs [poly(tetraphenyl phthalazine ether sulfone-quaternary ammonium hydroxide)]s were synthesized via chloromethylation of PTPPES, quaternization with trimethylamine, and followed by an anion exchange of tetra-quaternary ammonium chloride polymers with KOH. Different contents of quatemized unit in PTPPES-QAH (15, 20, 25 mol% of BFBTPB) were studied by FT-IR, H-1 NMR spectroscopy, and thermogravimetric analysis (TGA). Sorption experiments were conducted to observe the interaction of quatemized polymers with water. The ion exchange capacity (IEC), ion conductivity and cell performance of PTPPES-QAH were evaluated with increasing the degree of quaternization.
