Abstract
New (E)-5-[2-(5-nitrofuran-2-yl)vinyl]-1,2,4-oxadiazoles and 5-(5-nitrofuran-2-yl)-1,2,4-oxadiazoles were synthesized via the base-promoted condensation of nitrofuran-containing acyl chlorides with amidoximes. Testing these compounds against Gram-negative E. coli, Gram-positive B. subtilis and S. aureus as well as M. tuberculosis HRv37 strain revealed three compounds being selectively antimycobacterial. None of these compounds displayed any cytotoxicity towards human pancreatic epithelioid carcinoma cell line, PANC-1.
