4-naphthoquinone presented strong activity, e.g., 2-bromo-5-hydroxy-1,4-naphthoquinone, which exhibited inhibition at an MIC of 16 µg/mL in S. aureus, and 2-chloro-5,8-dihydroxy-1,4-naphthoquinone, with an MIC of 2 µg/mL in C. krusei. These compounds showed higher activity against fungi, but the antibacterial activities were very low. The study of structure–activity relationships is very important in the search
1,4-萘醌衍生物的合成备受关注,因为这些化合物作为抗疟疾,抗菌,抗真菌和抗癌剂具有很强的活性。合成了一系列50种萘醌衍生物,并使用肉汤微稀释法评估了其对大肠杆菌,铜绿假单胞菌,粪肠球菌,金黄色葡萄球菌,克鲁斯假丝酵母,副念珠菌和新隐球菌的抗菌和抗真菌活性。该念珠菌种是最易感的微生物。1,4-萘醌的卤素衍生物具有很强的活性,例如2-溴-5-羟基-1,4-萘醌,在金黄色葡萄球菌和2-chloro-5中的MIC为16 µg / mL时表现出抑制作用,8-二羟基-1,4-萘醌,在克鲁氏梭菌中的MIC为2 µg / mL 。这些化合物显示出较高的抗真菌活性,但抗菌活性非常低。由于药库的限制,结构-活性关系的研究对于寻找新的抗微生物药物非常重要。
