The ligand [2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline] (L) have been prepared from 2,3-dichloroquinoxaline and 3-(2-pyridyl)-1H-pyrazole. The reaction of N,N?-bidentate chelating ligand (L) and the corresponding metal precursors [(arene)Ru(mu-Cl)Cl]2 {arene = p-cymene, benzene, hexamethylbenzene (HMB)}, [Cp?M(mu-Cl)Cl]2 {Cp? = pentamethylcyclopentadiene; M = Rh, Ir}, [CpRuCl(PPh3)2] {Cp = cyclopentadiene; PPh3 = triphenylphosphine} and [Re(CO)5Br] leads to the formation of mononuclear metal complexes having the general formula [(arene)Ru(L)Cl]+ where, arene = p-cymene (1), C6H6 (2), C6Me6 (3), [Cp?M(L)Cl]+ where, M = Rh (4), Ir (5), [CpRu(L)PPh3]+ (6) and [Re(L)(CO)3Br] (7). All these platinum group metal complexes were synthesized and isolated with PF6 counter anions except complex (6) whereas the complex (7) was isolated as a neutral complex. All these metal complexes were fully characterized by FT-IR, 1H NMR, UV-Vis and mass spectroscopic and analytical techniques. Moreover, the complexes (1-7) were determined by the single-crystal X-ray diffraction analysis. Single crystal X-ray data confirms that the coordination occurs to the N-atoms of the pyridyl and pyrazolyl moieties of the ligand. Agar well diffusion method reveals that complexes (1, 2, 4 and 5) are having good antibacterial activity against the three different bacteria, pathogenic test organisms Staphylococcus aureus subsp. aureus, Staphylococcus epidermidis and Escherichia coli. The electronic transitions and absorption band of the complexes calculated by using time-dependent DFT method are in good agreement with the experimental results.

Steroidal [oxazolo(4,5-b)quinoxaline-2-yl-hydrazone] derivative (7a-9a) (7b-9b) were prepared by the multi-step reactions of steroid. It is prepared via the reaction of steroidal semicarbazones with 2,3-dichloroquinoxaline at 80C in ethanol. The structures of the compounds were evident by IR, 1H NMR and mass spectrometry and their purities were confirmed by elemental analyses. The antibacterial activity of these compounds was evaluated by the disk diffusion assay against two Gram-positive and two Gram-negative bacteria and then the minimum inhibitory concentration (MIC) of compounds was determined. The results showed that compounds (7a, 7b, 8a, 8b) are better antibacterial agent as compared with the standard drug amoxicillin.

New Advances in Chemical Research, May 2021. In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C10H10N2O3, We’ll be discussing some of the latest developments in chemical about CAS: 16915-79-0, name is 2-(Hydroxymethyl)-3-methylquinoxaline 1,4-dioxide. In an article，Which mentioned a new discovery about 16915-79-0

We developed a simple and efficient method for fabricating a taste-masked oral drug delivery system (DDS) that regulates the release of unpleasant drug taste via the change in pH value in the physiological environment of the alimentary canal. In this drug delivery system, a pH-sensitive metal-organic coordination polymer (CP), Fe-4,4?-bipyridine (Fe-bipy) complex, works as a taste-masker. The pH-sensitive Fe-bipy was grafted onto the mesoporous silica nanoparticles (MSNs) containing the model bitter drug mequindox (MEQ) in its mesopores through metal-organic coordination cross-linking, resulting in the CP-coated nanodrug MSN-NH2-MEQ@Fe-bipy. In artificial saliva (pH 6.6), Fe-4,4?-bipyridine CPs effectively prevent the leaking of the loaded guest molecule MEQ. On the other hand, in artificial gastric fluid (pH 1.0), the coordination bonds of the Fe-4,4?-bipyridine complex were broken, leading to the release of MEQ molecules from MSN-NH2-MEQ@Fe-bipy. The results indicate that the simple and efficient preparation method for taste-masked MSN-NH2-MEQ@Fe-bipy could provide new insights into taste-masking technology by using pH-responsive smart nanomaterials.

Thirty-one quinoxalines bearing a substituted benzylamino group on position 2 and various substituents on position 3, 6, 7 and 8 of the heterocycle were prepared in order to evaluate in vitro anticancer activity. Preliminary screening performed at NCl on twenty-two compounds showed that most derivatives exhibited a moderate to strong growth inhibition activity on various tumor panel cell lines between 10-5 and 10-4 molar concentrations. Interesting selectivities were also recorded between 10-8 and 10-5 M.

Until recently, discriminating between homomeric 5-HT3A and heteromeric 5-HT3AB receptors was only possible with ligands that bind in the receptor pore. This study describes the first series of ligands that can discriminate between these receptor types at the level of the orthosteric binding site. During a recent fragment screen, 2-chloro-3-(4-methylpiperazin-1-yl)quinoxaline (VUF10166) was identified as a ligand that displays an 83-fold difference in [3H]granisetron binding affinity between 5-HT3A and 5-HT3AB receptors. Fragment hit exploration, initiated from VUF10166 and 3-(4-methylpiperazin-1-yl)quinoxalin-2-ol, resulted in a series of compounds with higher affinity at either 5-HT3A or 5-HT3AB receptors. These ligands reveal that a single atom is sufficient to change the selectivity profile of a compound. At the extremes of the new compounds were 2-amino-3-(4-methylpiperazin-1-yl)quinoxaline, which showed 11-fold selectivity for the 5-HT3A receptor, and 2-(4-methylpiperazin-1-yl)quinoxaline, which showed an 8.3-fold selectivity for the 5-HT3AB receptor. These compounds represent novel molecular tools for studying 5-HT3 receptor subtypes and could help elucidate their physiological roles.

The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 80636-30-2, Name is 3,3-Dimethyl-3,4-dihydroquinoxalin-2(1H)-one, molecular formula is C10H12N2O. In a article，once mentioned of 80636-30-2

A highly efficient and versatile method for the synthesis of quinoxaline derivatives with two benzimidazole fragments have been developed on the basis of the ring contraction of 3-(benzimidazo-2-yl)quinoxalin-2(1H)-one with 1,2-diaminobenzene and its various types of substituted and condensed derivatives. Owing to the inter- and intramolecular processes, involving self association, proton exchange, conformational, and/or tautomeric exchanges between several forms for most of the bis-benzimidazolylquinoxalines signals of bridged and neighboring carbon atoms and the hydrogen atoms of the neighboring carbon atoms of benzimidazole fragments in the NMR spectra are broadened. The conjugation between the benzimidazole fragments and the quinoxaline core of the molecules is increased from the quinoxaline derivative (10c) to its thiadiazol[f]- (17) and pyrrolo[a]-(19) annulated derivatives, resulting in a greater planarity of the molecule as a whole.
