Diastereoselective Three-Component Vinylogous Mannich Reaction of Nitrogen Heterocycles, Acyl/Sulfonyl Chlorides, and Silyloxyfurans/pyrroles

A one-step, 3-component vinylogous Mannich reaction of trimethylsilyloxyfuran or N-protected tert-butyldimethylsilyloxypyrrole with a variety of nitrogen-containing heterocycles in the presence of diverse electrophiles is described. The reaction products were generally obtained in high yields and as a single diastereoisomer having the (R*,R*) relative configuration based on crystallographic studies of several derivatives. Several azaheterocycles were successfully used for this reaction, such as isoquinolines, quinoline, phenanthridine, quinazoline, phthalazine, and beta-carboline, and electrophiles included acetyl chloride, methyl chloroformate, methyl chloromalonate, 2-bromobutanoyl chloride, and arylsulfonyl chlorides. The products of the vinylogous Mannich reactions were subjected to further transformations, leading to highly functionalized and stereochemically defined tetracyclic derivatives that are valuable building blocks for the preparation of natural products or medicinal agents.

Ruthenium Catalyzed C-H Amidation and Carbocyclization using Isocyanates: An Access to Amidated 2-phenylphthalazine-1,4-diones and Indazolo[1,2-b]phthalazine-triones

A direct carbocyclization of 2-aryl-2,3-dihydrophthalazine-1,4-diones is achieved using isocyanates as carbonyl source via Ru(II)-catalyzed sequential ortho-amidation followed by intramolecular nucleophilic substitution, delivering substituted indazolo[1,2-b]phthalazine-triones in good-to-excellent yields. For ortho-substituted 2-aryl-2,3-dihydrophthalazine-1,4-diones, the corresponding amidated products were also isolated in excellent yields by modifying the reaction parameters. Application of isocyanates as carbonyl source, high functional group tolerance on the two coupling partners and diverse chemical transformation of the synthesized fused and functionalized phthalazinones are the key highlights of the work.

Genetic variants of aldehyde oxidase (AOX) 1 in cynomolgus and rhesus macaques

The cynomolgus macaque is a non-human primate species widely used in drug metabolism studies. Despite the importance of genetic polymorphisms in cytosolic aldehyde oxidase (AOX) 1 in humans, genetic variants have not been investigated in cynomolgus or rhesus macaques. Genetic variants in AOX1 were identified and allele frequencies were assessed using the genomes of 24 cynomolgus and 8 rhesus macaques. The analysis identified 38 non-synonymous variants, some of which were unique to cynomolgus macaques (bred in Cambodia, Indochina, or Indonesia) or rhesus macaques, whereas many variants were shared by the two lineages. Among the variants observed at relatively high frequencies, eight were selected for functional analysis. Recombinant P605L and V1338I AOX1 variants showed substantially lower phthalazine and carbazeran oxidation activities than the wild-type AOX1 protein. In liver cytosolic fractions from cynomolgus and rhesus macaques genotyped for P605L and V1338I AOX1, groups of cytosolic fractions with P605L and/or V1338I AOX1 variants showed significantly lower phthalazine and carbazeran oxidation activities than the wild type. These results indicate that AOX1 is polymorphic in cynomolgus and rhesus macaques, just as it is in humans. Further investigation is needed to reveal the functional significance of these AOX1 variants in drug metabolism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 90-64-2, in my other articles.

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.

Synthesis and Antitumor Activity of 1-Phenyl-4-substituted Phthalazine Derivatives

In order to find more efficient and economical antitumor drugs, a series of 1-phenyl-4-substituted phthalazine derivatives were synthesized and evaluated for antiproliferative activity in vivo. The structures of the synthesized compounds were confirmed by H-1 NMR, C-13 NMR and HRMS. The antitumor activity of the target compounds was performed against four cancer cell lines by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT). The results showed that some compounds had a good antitumor activity, especially, N-(4-methoxyphenyl)-2-((4-phenylphthalazin-1-yl)thio)acetamide (5f) and N-(3-chloro-4-fluorophenyl)-2-(4-(4-phenylphthalazin-1-yl)piperazin-1-yl)acetamide (8c), exhibited better antitumor activities with IC50 values of 8.13 and 9.31 mu mol.L-1 against the human esophageal cancer cells, which were superior to 5-fuorouracil.

Synthesis, Characterization and Antimicrobial Activity of Bis(Phthalimido)Piperazine and its Derivatives: a New Class of Bioactive Molecules with Enhanced Safety and Efficacy

Piperazine rings are important heterocyclic targets in organic synthesis and are useful synthetic intermediates or intricate parts of biologically active molecules. In our efforts, a series of piperazine derivatives has been prepared discovering new classes of antimicrobial agents, including bis(phthalimido)piperazine, bis(3-aminopropyl) piperazine, 2,3-dihydro-phthalazine-1,4-dione, and bis(3,4-aminophenol)piperazine. The synthesized antimicrobial agents have been studied using various spectroscopic techniques. Furthermore, these compounds have been screened for their in vitro antimicrobial activity against selected bacterial and fungal strains. Three compounds exhibited mild to good antibacterial activity, but somewhat lower antifungal activity against tested microbial strains.
