Synthesis and antitumor evaluations of symmetrically and unsymmetrically substituted 1,4-bis[(aminoalkyl)amino]anthracene-9,10-diones and 1,4-bis[(aminoalkyl)amino]-5,8-dihydroxyanthracene-9,10-diones

or 8 with a different diamine leads to the unsymmetrically substituted 1,4-bis[(aminoalkyl)amino]anthracene-9,10-diones 9 and 10, respectively. Many of the synthetic unsymmetrical analogues have been evaluated for their antitumor activity against L1210 in vitro and in vivo. Cross resistance of analogue 10a with mitoxantrone (2) and doxorubicin was evaluated against MDR lines in vitro against human colon
1,4-二氟蒽-9,10-二酮(3)和1,4-二氟-5,8-二羟基蒽-9,10-二酮(4)的过量二胺(或a)氟化物的ipso bis置换在室温下,在吡啶中分别得到对称的1,4-双取代的类似物5和6。可以通过用小于1摩尔当量的二胺(或单胺)处理分别产生7和8来实现氟化物从3和4的ipso单取代。用不同的二胺处理7或8分别导致不对称取代的1,4-双[(氨基烷基)氨基]蒽9,10-二酮9和10。已经评估了许多合成的不对称类似物在体外和体内对L1210的抗肿瘤活性。评价了类似物10a与米托蒽醌(2)和阿霉素的交叉抗性,体外针对MDR株抗人结肠癌LOVO及其对DOXO的亚株(LOVO / DOXO)的交叉抗性。提出和讨论了观察到的细胞毒性的潜在机制。
