Synthesis of New Pyrimido[5?,4?:5,6][1,4]thiazino[2,3-b]quinoxaline Derivatives in One Step

As a continuation of our search for new heterocyclic compounds, the synthesis of pyrimido[5?,4?:5,6][1,4]thiazino[2,3-b]quinoxaline ring system is described. A series of new derivatives of this heterocyclic system (3a?d) have been synthesized through the one-pot heterocyclization of the appropriate 5-amino6-methylpyrimidine-4-thiols and 2,3-dichloroquinoxaline in the presence of K2CO3 in dimethylformamide under reflux. N-alkylation of the synthesized compounds with alkyl halides in KOH/dimethylformamide also gave the desired new derivatives of N-alkylated pyrimido[5?,4?:5,6][1,4]thiazino[2,3-b]quinoxalines (4a?h). All the synthesized products were characterized and confirmed by their spectroscopic and microanalytical data.

Ethyl (6,7-dimethyl-2-oxo-3,4-dihydroquinoxalin-3-yl)acetate and ethyl (6-methyl-2-oxo-3,4-dihydroquinoxalin-3-yl)acetate (1a,b), 3-methylquinoxalin-2(1H)-one (4) and 1,4-dihydroquinoxaline-2,3-dione (11) were the starting precursors for nine novel quinoxaline compounds, 3a, 6, 10, 13, 15, 16, 17, 18, and 20, via adopting different nucleophilic reactions. The synthesized compounds were tested for their antiviral activity against HCV, HBV, HSV-1, and HCMV. Concomitantly, their safety profile was investigated as well as their selectivity against the viral strains. The Virology Unit at the University of Alabama recorded that two compounds, i.e., 1a and 20, exhibited highly potent activity against HCMV with lower IC50 values (<0.05 muM) compared to ganciclovir (IC50 = 0.59 muM). Compounds 1a and 20 also exhibited low cytotoxicity together with a high selectivity index.

Fluorescent sensing of anions using a bis-quinoxaline amidothiourea based supramolecular cleft; an example of an anion-induced deprotonation event

The quinoxaline 1, possessing a 2,6-pyridyl-based amidothiourea moiety, with the view of forming a pre-organised molecular cleft, was developed as a fluorescent anion sensor. The sensing ability of 1 was evaluated in organic solution where both the ground and the excited state of 1 was affected upon recognition of anions such as acetate [as tetrabutylammonium salt (TBAAc) solution] at the amiodothiourea moieties in MeCN. The fluorescence of 1, with lambdamax at 477 nm, was, on all occasions quenched, upon anion recognition. Using TBAOH, we also show that the same anion-induced changes occurred; demonstrating that for this particular sensor, the anion-sensing takes place via a deprotonation mechanism. This anion-induced deprotonation event was further investigated by carrying out 1H NMR titrations on 1, using both AcO- and OH- in DMSO-d6.
