To find novel amphotericin B (AmB) derivatives with high therapeutic potential, low toxicity, and water solubility, a series of nine N-substituted AmB derivatives were evaluated for their antifungal activity using the broth dilution method and for their hemolytic toxicity with sterile defibrinated sheep blood. Qualitative screening of the effect of the derivatives on two reference Candida albicans strains
为了找到具有高治疗潜力,低毒性和水溶性的新型两性霉素B(AmB)衍生物,使用肉汤稀释法评估了九种N-取代的AmB衍生物的抗真菌活性,以及对无菌去纤维化绵羊的溶血毒性血。基于n的值(n为正整数)对衍生物对两种参考白色念珠菌菌株的影响及其溶解度进行定性筛选,从而鉴定出最佳化合物NH 2-(AEEA)5-AmB(DMR005; AEEA是8-氨基-3,6-二氧杂辛酸)。DMR005的初步安全性评估是通过体外MTT细胞活力测定和体内急性毒性测定进行的。通常,DMR005不仅比母体多烯具有更高的水溶性和更低的毒性,而且还保留了抗真菌效力。
