cytotoxic properties of the 2-(2'-pyridyl)- and 2-(2'-aminophenyl)-7-aminoquinoline-5,8-diones. A direct comparison of the antimicrobial and cytotoxic properties of a complete set of streptonigrin and lavendamycin partial structures is detailed in efforts to define the role peripheral substituents play in potentiating the biological properties of the naturally occurring and synthetic agents bearing the 7-aminoquinoline-5
7-氨基-5,8-二氧-2-(2'-吡啶基)喹啉-6'-羧酸(5a)和7-氨基-2-(2'-氨基苯基)-5,8的制备和评价详细介绍了构成潜在最低限度的-dioxoquinoline-5'-羧酸(6a),链霉菌素(1a)和拉文霉素(2a)这两种与结构相关的天然抗肿瘤抗生素的有效药效团。与链霉菌素和拉文霉素有关的观察结果相反,在这种观察中,C环C-6'羧酸增强了天然存在的取代7-氨基喹啉5,8-二酮AB环系统的抗肿瘤,抗微生物和细胞毒性。 5a / 6a的C-6'/ C-5'羧酸降低了2-(2'-吡啶基)-和2-(2'-氨基苯基)-7-氨基喹啉-5,8的抗菌和细胞毒性-diones。为了确定外围取代基在增强天然存在的和带有7-氨基喹啉5的合成剂的生物学特性中所起的作用,详细介绍了完整的链霉菌素和拉维达霉素部分结构的抗微生物和细胞毒性特性的直接比较。 8-dione AB环系统并努力确定天然存在
