Since utilization of menaquinone in the electron transport system is a characteristic of Gram-positive organisms, the 1,4-dihydroxy-2-naphthoate prenyltransferase (MenA) inhibitors 1a and 2a act as selective antibacterial agents against organisms such as methicillin-resistant Stapylococcus aureus (MRSA), Staphylococcus epidermidis (MRSE), and Mycobacterium spp. Growth of drug-resistant Gram-positive organisms was sensitive to the MenA inhibitors, indicating that menaquinone synthesis is a valid new drug target in Gram-positive organisms.
由于甲萘醌在电子传递系统中的利用是革兰氏阳性菌的一个特性,1,4 - 二羟基 - 2 - 萘甲酸异戊烯基转移酶(MenA)抑制剂1a和2a可作为针对耐甲氧西林金黄色葡萄球菌(MRSA)、表皮葡萄球菌(MRSE)和分枝杆菌属等细菌的选择性抗菌剂。耐药革兰氏阳性菌的生长对MenA抑制剂敏感,这表明甲萘醌合成是革兰氏阳性菌中一个有效的新药物靶点。
