In continuing our study of the relationship between structures and antibacterial activity, 2-[2-(5-nitro-2-furyl)vinyl]-5-hydroxy- and 4-[2-(5-nitro-2-furyl)vinyl]-2,7-dihydroxy-1,8-naphthyridine and their related derivatives have been synthesized. In these compounds, 2-[2-(5-nitro-2-furyl)vinyl]-5-hydroxy- (I) and 2-[2-(5-nitro-2-furyl)vinyl]-5-hydroxy-6-ethoxycarbonyl-1,8-naphthyridine (II) showed broad spectra of antibacterial activity, and the activity of I was greater than that of II. Other compounds exhibit a strong antibacterial activity against Diplococcus pneumoniae, Streptococcus hemolyticus, and Staphilococcus aureus, but they show a weak activity against the other microorganisms tested.
为了继续研究结构与抗菌活性之间的关系,我们合成了 2-[2-(5-硝基-2-呋喃基)乙烯基]-5-羟基和 4-[2-(5-硝基-2-呋喃基)乙烯基]-2,7-二羟基-1,8-萘啶及其相关衍生物。在这些化合物中,2-[2-(5-硝基-2-呋喃基)乙烯基]-5-羟基-(I)和 2-[2-(5-硝基-2-呋喃基)乙烯基]-5-羟基-6-乙氧羰基-1,8-萘啶(II)显示出广泛的抗菌活性谱,且 I 的活性高于 II。其他化合物对肺炎双球菌、溶血性链球菌和金黄色葡萄球菌具有较强的抗菌活性,但对其他微生物的活性较弱。
