The conjugation of methotrexate (Mtx) with a siderophore to construct “Trojan horse” antibacterial conjugates is reported. The most potent conjugate exhibited over 1000-fold improved activity against Gram-positive Streptococcus pneumoniae and Gram-negative Yersinia enterocolitica compared with Mtx, while possessing 2313-fold reduced human cytotoxicity, resulting in 2.08×106-fold improvements in the
报道了甲氨蝶呤 (Mtx) 与铁载体的结合以构建“特洛伊木马”抗菌结合物。与 Mtx 相比,最有效的缀合物对革兰氏阳性肺炎链球菌和革兰氏阴性小肠结肠炎耶尔森菌的活性提高了 1000 倍以上,同时对人体细胞毒性降低了 2313 倍,导致治疗指数提高了2.08×10 6倍。
