A series of novel hybrid molecules containing sulfanilamide and thiourea templates was designed and synthesized. These compounds were screened for antimicrobial and urease inhibitory activities. Some of the compounds revealed promising antibacterial and antifungalactivities. Fascinatingly, the majority of the compounds exhibited potential urease inhibitory activities with IC50 ranging from 0.20 to
A series of 3-aroyl-1-(4-sulfamoylphenyl)thiourea derivatives containing sulfonamide moiety were designed and synthesized as 15-lipoxygenase (15-LOX) inhibitors. Most synthesized compounds showed potent activity against soybean 15-LOX with IC50 values less than 25 mu M. The most potent compound 4c (3-methylbenzoyl derivative) with IC50 value of 1.8 mu M was 10-fold more potent than quercetin. Interestingly, compound 4c also showed the highest antioxidant activity, as determined by ferric reducing antioxidant power (FRAP) assay. Its capacity for reducing ferric ion was more than ascorbic acid. The viability assay of the selected compound 4c against oxidative stress-induced cell death in differentiated PC12 cells revealed that compound 4c significantly protected neurons against cell death in low concentrations.
