Abstract: Nitrothiazole derivatives have been reported to exhibit activity against aerobic, anaerobic, and microaerophilic bacteria. This activity profile makes the nitrothiazole compound class an ideal lead source against Mycobacterium tuberculosis, which flourishes in varied environments with different oxygen concentrations. In this work, we investigated six nitrothiazole derivatives for antitubercular activity. The compounds exhibited potent activity, with compounds 9 and 10 possessing an equipotent MIC90 value of 0.24 μM. The compounds were investigated for cytotoxicity against HEK293 cells and hemolysis against red blood cells, and they demonstrated no cytotoxicity nor hemolytic effects, suggesting they possess inherent antitubercular activity.

60% | In water; hydrogen bromide; sodium nitrite; | 2-Bromo-5-nitrothiazole To 72.5 g of 2-amino-5-nitrothiazole in 300 mL of 48percent hydrobromic acid and 200 mL of water stirred and cooled to about -10° C. was slowly added, in portions, 51.8 g of sodium nitrite dissolved in 80 mL of water from one addition funnel and 250 mL of n-amyl alcohol from a second addition funnel. The addition of both solutions required about 3 hours. The cooling bath was removed and the mixture allowed to warm to about 15° C. overnight and then stirred at room temperature for 2 hours. The solid was collected by vacuum filtration and steam distilled to give 67 g of crude product. The crude product was recrystallized from hot ethanol to give 61 g (60percent yield) of the 2-bromo-5-nitrothiazole as a yellow solid. |
