alkylamines provided the target "two-armed" anthrapyrazoles. A-ring 7,10-dihydroxy anthrapyrazoles were derived from amine condensation with intermediate 5-chloro-7,10-dihydroxyanthrapyrazoles or, alternatively, from intermediate 5-chloro-7,10-bis(benzyloxy)anthrapyrazoles followed by hydrogenolysis of the benzyl protecting groups to provide the target compounds. Potent in vitro activity was demonstrated against
试图提供与米托蒽醌有关的蒽酮二酮的发色团修饰,以试图提供减少或没有心脏毒性的药剂,从而产生了新型的DNA结合物,蒽吡唑。它们的合成是通过从所需的1,4-或1,5-二氯-9,10-蒽二酮前体开始的两步缩合序列进行的。与单烷基肼反应得到氯蒽吡唑中间体,其随后与伯或仲烷基胺的缩合提供了目标“两臂”蒽吡唑。A环7,10-二羟基蒽唑是由胺与中间体5-氯-7,10-二羟基蒽唑的缩合反应衍生而来的,也可以是由中间体5-氯-7,10-双(苄氧基)蒽吡唑,然后氢解苄基保护基以提供目标化合物。在广泛的结构变异中,体外抗鼠L1210白血病(IC50 = 10(-7)-10(-8)M)以及体内P388白血病表现出强大的体外活性。通常,通过在N-2和C-5处的碱性侧链,侧链近端和远端氮之间的2至3个碳间隔基以及A环羟基化,可以最大限度地提高针对P388系的活性。除了具有针对P388品系的治疗活性外,更具活性的化合物
