Design, Regiospecific Green Synthesis, Chemical Computational Analysis, and Antimicrobial Evaluation of Novel Phthalazine Heterocycles

Phthalazines have received considerable attention for their wide antimicrobial activity. Regiospecific nucleophilic attack of 4-benzylphthalazin-1-ol by the 1-oxo rather than the aza group on different alkyl halides gave novel phthalazine heterocyclic derivatives. Moreover, a variety of nucleosides bonded to electron-withdrawing groups were synthesized using 4-benzylphthalazine-1-ol. The density functional theory has been used to investigate the electronic structure of the synthesized compounds. All of the synthesized derivatives showed remarkable activity when tested against Gram-positive and Gram-negative bacteria, Aspergillus niger, and Candida albicans. The reactivity of these nucleosides was expected to arise from their bonding with the lone pair of N-atom of the macromolecules of bacteria. These bonding were expected to inhibit the enzyme by forming highly stable complex with lower highest occupied molecular orbital energy. The structures of these synthesized derivatives were established by Fourier transform infrared, H-1-NMR, and C-13-NMR spectroscopic evidence.

A high-strength PPESK/PVDF fibrous membrane prepared by coaxial electrospinning for lithium-ion battery separator

Electrospinning fibrous membranes have attracted a great deal of attention because of their advantages, including uniform pore size, large ratio surface area, and high porosity. For extended application in lithium-ion battery, it is essential to further improve their electrochemical, mechanical, and thermal properties. In this work, a new poly (phthalazine ether sulfone ketone) (PPESK)/polyvinyli-denefluoride (PVDF) core/shell fibrous membrane was fabricated via the coaxial electrospinning technique, followed by hot press. The PPESK/PVDF membrane hot pressed at 160 degrees C exhibits excellent comprehensive performance, including large porosity (80%), high electrolyte uptake (805%), and excellent thermal stability (at 200 degrees C). Moreover, due to the improved bonding effect derived from the solidification of the PVDF shell layer after the hot press, the mechanical property of the membrane is effectively enhanced. The electrochemical tests also indicate that the PPESK/PVDF membrane shows larger ionic conductivity and lower interfacial resistance when compared with commercial microporous polypropylene separator. In addition, simulated cells assembled with the PPESK/PVDF membrane present superior discharge capacity, stable cycle performance, and excellent rate capability. Therefore, the hot-pressed coaxial PPESK/PVDF fibrous membrane has the potential to be a promising candidate as the separator for high-performance lithium-ion battery.

Ligand Redox-Controlled Tandem Synthesis of Azines from Aromatic Alcohols and Hydrazine in Air: One-Pot Synthesis of Phthalazine

A controlled tandem synthetic route to azines from various alcohols and hydrazine hydrate by the use of a Ni(II) complex of 2,6-bis(phenylazo)pyridine as a catalyst is reported. In marked contrast to the previous report, the reaction is operative using an earth-abundant metal catalyst, milder reaction conditions, and aerobic conditions, which though are desirable but unprecedented in the literature. The catalytic reaction has a vast substrate scope including a single-step synthesis of phthalazine from 1,2-benzenedimethanol and hydrazine hydrate via intramolecular coupling. Mechanistic investigation suggests that the coordinated ligand redox controls the reaction by the use of a reversible azo (N=N)/hydrazo (NH-NH) redox couple where the metal center is used primarily as a template.

A New Pathway for Phthalazine Derivatives via Metal-Free Cyclization of ortho-Alkynylphenyl Ketones and Hydrazine

A one-step synthetic protocol for phthalazine derivatives has been developed. In the presence of Et3N, a series of phthalazine derivatives were conveniently prepared in high yield by the reaction of ortho-alkynylphenyl ketones and hydrazine under mild reaction conditions. The structure was unambiguously confirmed by X-ray crystallographic analysis of product 2i.

One-pot synthesis of 2H-indazolo[2,1-b]phthalazine-triones via nano gamma-Al2O3/BF3/Fe3O4 as an efficient catalyst and theoretical DFT study on them

Experimental and computational studies were carried out for the synthesis of 2H-indazolo[2,1-b]phthalazine-triones using gamma-Al2O3/BF3/Fe3O4 as a nanocatalyst in optimized and solvent-free conditions. The most significant features of the existing protocol are easy preparation of the catalyst, short reaction times, environmentally benign, and milder reaction conditions.

Structure-activity relationship for enantiomers of potent inhibitors of B. anthracis dihydrofolate reductase

Background: Bacterial resistance to antibiotic therapies is increasing and new treatment options are badly needed. There is an overlap between these resistant bacteria and organisms classified as likely bioterror weapons. For example, Bacillus anthracis is innately resistant to the anti-folate trimethoprim due to sequence changes found in the dihydrofolate reductase enzyme. Development of new inhibitors provides an opportunity to enhance the current arsenal of anti-folate antibiotics while also expanding the coverage of the anti-folate class. Methods: We have characterized inhibitors of B. anthracis dihydrofolate reductase by measuring the K-i and MIC values and calculating the energetics of binding. This series contains a core diaminopyrimidine ring, a central dimethoxybenzyl ring, and a dihydrophthalazine moiety. We have altered the chemical groups extended from a chiral center on the dihydropyridazine ring of the phthalazine moiety. The interactions for the most potent compounds were visualized by X-ray structure determination. Results: We find that the potency of individual enantiomers is divergent with clear preference for the S-enantiomer, while maintaining a high conservation of contacts within the binding site. The preference for enantiomers seems to be predicated largely by differential interactions with protein residues Leu29, Gln30 and Arg53. Conclusions: These studies have clarified the activity of modifications and of individual enantiomers, and highlighted the role of the less-active R-enantiomer in effectively diluting the more active S-enantiomer in racemic solutions. This directly contributes to the development of new antimicrobials, combating trimethoprim resistance, and treatment options for potential bioterrorism agents. Published by Elsevier B.V.

Synthesis of hydralazine-N-lactose and its metabolites in vitro

Hydralazine-N-lactose is a main impurity in hydralazine tablets. Hydralazine and lactose were used as raw materials, and silica gel column and preparation column of octadecylsilane bonded silica were selected to prepare and purify hydralazine-N-lactose. Its in vitro metabolites were identified by utilizing SD rat liver microsomes. The results of samples in vitro were compared with blank group and the resulting metabolites structures were identified by LC-MS/MS. Hydrazine-N-lactose produced six main metabolites, including s-triazolo[3, 4-a] phthalazine, 3 -methyl-s-triazolo [3, 4-a] phthalazine, 3 -(1-hydroxy) methyl-s-triazolo [3, 4-a] phthalazine, 3 hydroxymethyl-s-triazolo[ 3, 4-a] phthalazine, hydralazine and dehydro-hydralazine-N-lactose after in vitro metabolism. This study will be valuable in hydralazine-lactose conjunctions metabolism research and hydralazine formulation safety.
