What is quinoxaline used for?
Quinoxalines are another important class of heterocyclic compounds, associated with wider pharmacological applications [71–73]. They are used in the treatment of bacterial, cancer, and HIV infections [74–77].
What is the meaning of quinoxaline?
A quinoxaline, also called a benzopyrazine, in organic chemistry, is a heterocyclic compound containing a ring complex made up of a benzene ring and a pyrazine ring. It is isomeric with other naphthyridines including quinazoline, phthalazine and cinnoline.
Which of the following is an example of quinoxaline derivatives *?
Quinoxaline derivatives have been found to play a broad spectrum of biological activities including antibacterial, antiviral, as kinase inhibitors, anti-inflammatory, anthelmintic, and anticancer [24]. The quinoxaline ring is a part of many antibiotics such as echinomycin, levomycin, and actinomycin.
What is green synthesis of quinoxaline?
A simple and catalyst free synthetic method has been developed by the synthesis of quinoxaline derivatives from 2-chloro quinoxaline and different types of amine derivatives using PEG-400 green solvent at room temperature. PEG-400 increases the rate of reaction and reduces reaction time.
What is the melting point of 2/3 diphenyl quinoxaline?
125-127 °C
mp. 125-127 °C (lit.)
What is coumarin used for?
Coumarins are commonly used in the treatment of prostate cancer, renal cell carcinoma and leukemia, and they also have the ability to counteract the side effects caused by radiotherapy. Both natural and synthetic coumarin derivatives draw attention due to their photochemotherapy and therapeutic applications in cancer.
Is Pyrazine basic?
Pyrazine is a heterocyclic aromatic organic compound with the chemical formula C4H4N2. It is a symmetrical molecule with point group D2h. Pyrazine is less basic than pyridine, pyridazine and pyrimidine. Pyrazine and a variety of alkylpyrazines are flavor and aroma compounds found in baked and roasted goods.

Which solvent is used for the synthesis of 2/3 diphenyl quinoxaline?
This is a method of condensation of an aryl 1,2-diamine with a 1,2-dicarbonyl compound by heating in a solvent like rectified sprit. Here condensation reaction of 1,2-diamines with α-diketones occurs with cyclization. Aim: To prepare 2,3- diphenylquinoxaline from benzyl.
What is the melting point range of Diphenylquinoxaline?
Is coumarin soluble in water?
Those are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Coumarin is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa).
