Abstract
New strategies targeting the synthesis of novel triazine sulfonamides as potent antiviral agents have been accomplished via reacting the sulfaguanidine derivatives with N-cyanodithioiminocarbonate. Further reaction of the new triazine sulfonamides with various secondary amines furnished several substituted triazine sulfonamide derivatives of promising broad-spectrum activities. New class of triazine sulfonamide thioglycosides was also designed and synthesized. The new structures were generated via a direct approach starting from potassium cyanocarbonimidodithioate, then the corresponding triazine sulfonamide thioglycosides were generated. Characterizations of the compounds have been determined utilizing NMR spectroscopy and single crystal X-ray diffraction technique. The anti-viral activity of the compounds against SARS CoV-2 virus was investigated utilizing MTT cytotoxicity assay to estimate the half-maximal cytotoxic concentration (CC50) and inhibitory concentration 50 (IC50). The most active compound demonstrated potent anti-viral potency against SARS-CoV-2 with IC50 = 2.378 µM as compared to the activity of the anti-viral drug remdesivir (IC50 = 10.11 µM). Anti-viral investigations of the triazine sulfonamide thioglycosides in vitro against HCoV-229E virus revealed that some compounds possess promising activity. Some compounds indicated moderate anti-viral activity against low pathogenic coronavirus 229E as compared to remdesivir at a concentration of 100 μg/mL. Our results demonstrate that these novel triazine sulfonamides could potentially serve as new anti-viral drugs.
