The sulfoxides 5-methylsulfinyl-2-furaldehyde semicarbazone (2) and 1-[(5-methylsulfinyl-2-fufurylidene)amino]hydantoin (3) as well as the sulfones 1-[(5-methylsulfonyl-2-furfurylidene)animo]hydantoin (1) and 1-(5-methylsulfonly-2-furyl)-2-(6-amino-3-p-ridazyl)ethylene hydrochloride (4) have been prepared and tested for antibacterial activity against a number of gram-negative and gram-positive organisms
亚砜5-甲基亚磺酰基-2-糠醛半卡巴zone(2)和1-[((5-甲基亚磺酰基-2-呋喃基)氨基]乙内酰脲(3)以及砜1-[(5-甲基磺酰基-2-糠基亚胺)苯胺制备了乙内酰脲(1)和1-(5-甲基磺基-2-呋喃基)-2-(6-氨基-3-对-叠氮基)乙撑盐酸盐(4),并测试了其对多种革兰氏菌的抗菌活性。阴性和革兰氏阳性生物。该化合物的活性比相应的5-硝基呋喃衍生物低得多,这可能是因为它们的还原电位太负,以至于它们无法干扰细菌中的还原酶系统。
