Abstract:

In the present study, addition of nitroso group at position 1 of 2-aminoanthraquinone (1) to yield 2-amino-1-nitroanthraquinone (2) was carried out by the reaction of compound (1) with sodium nitrite in water. Compound (2) was used as starting material to produce many new naphtho[2,3-<em>f</em>] quinoxaline-dione, trione, naphtho-pyrazole quinoxaline-dione, anthra-triazine-dione, naphtho-thiazole quinoxaline-dione and anthrabenzo-triazepine-dione derivatives by elimination of one molecule of water as an initial reaction step. The reacting moieties were nitroso and amino function groups to yiel

Abstract:

(E)-Pyrrolo[1,2-a]quinoxalin-4-yl)-1-(3,4,5-trimethoxyphenyl)prop-2-en-1-one was designed then synthesized using a multi-step pathway starting from commercially available 2-nitroaniline. Structure characterization of this original substituted pyrrolo[1,2-a]quinoxaline compound was achieved by using FT-IR, 1H-NMR, 13C-NMR, X-Ray and HRMS spectral analysis. This new pyrroloquinoxaline shows interesting cytotoxic potential against different human leukemia cell lines (MV4-11, K562, MOLM14 and Jurkat cells).

Abstract:

Quinoxaline, triazole and benzothiazole heterocycles plays an important role in modulating biological activity. The present work describes the biological evaluation of target molecules designed using autodock vina docker. Novel benzothiazole based [1, 2, 4]-triazolo [4, 3-a] quinoxalines were synthesized by condensation of substituted 2-amino benzothiazoles and 4-chloro triazoloquinoxalines. The synthesized compounds were characterized by analysis of physical and spectral data. All synthesized compounds were screened for antioxidant activity using 1, 1-Diphenyl-2-picrylhyrazyl radical scavengi

Abstract:

This study introduces a green and efficient method for synthesizing manganese nanoparticles (MnO₂-NPs) using Bunium persicum extract as a reducing agent. The resulting MnO₂-NPs, characterized by UV-vis spectroscopy, SEM, and XRD, displayed spherical shapes with sizes ranging from 43.17 nm to 80.94 nm. These nanoparticles exhibited notable antibacterial properties and served as effective catalysts in the synthesis of quinoxaline derivatives through the condensation of 1,2-diaminoarenes with 1,2-diketones or 2-bromo-1-arylethanone. The method demonstrated broad substrate tolerance, mild reaction

Abstract:

Oxidation of quinoxalineaminothiol with SCl2 or S2Cl2/Cl2 affords a series of compounds based on the quinoxaline-1,2,3-dithiazole framework QDTA. Under highly oxidizing conditions, the 1,2,3-dithiazolyl ring is opened to afford the acyclic dichlorosulfimino-sulfenyl chlorides Clx-QDTA-Cl3 (x = 0, 1, 2). Reduction of these "trichloro" compounds leads to ring closure. For x = 2, reduction using S2Cl2 affords the dithiazolylium chloride [Cl2-QDTA][Cl]. For all values of x, reduction with iodide ion (3 mol equiv) affords the corresponding dithiazolyl radical [Clx-QDTA]. The radicals can be isolate
