  Structure−Activity Relationships for Pyrido-, Imidazo-, Pyrazolo-, Pyrazino-, and Pyrrolophenazinecarboxamides as Topoisomerase-Targeted Anticancer Agents

  摘要：

  Heterocyclic phenazinecarboxamides were prepared by condensation of aminoheterocycles and 2-halo-3-nitrobenzoic acids, followed by reductive ring closure and amidation. They showed similar inhibition of paired cell lines that underexpressed topo II or overexpressed P-glycoprotein, indicating a non topo II mechanism of cytotoxicity and indifference to P-glycoprotein mediated multidrug resistance. Compounds with a fused five-membered heterocyclic ring were generally less potent than the pyrido[4,3-alpha]phenazines. A 4-methoxypyrido[4,3-alpha]phenazine (IC(50)s 2.5-26 nM) gave modest (ca. 5 day) growth delays in H69/P xenografts with oral dosing.

  A compound which is a heteroaromatic[a]phenazine carboxamide derivative of formula (I) 1 wherein X is a five- or six-membered heteroaromatic ring which contains one or two nitrogen atoms and which is unsubstituted or substituted by C 1 -C 6 alkyl, hydroxyl or C 1 -C 6 alkoxy; Q is C 1 -C 6 alkylene which is unsubstituted or substituted by C 1 -C 6 alkyl which is unsubstituted or substituted by a hydroxy group; and R 1 and R 2 which are the same or different are each C 1 -C 6 alkyl; or a pharmaceutically acceptable salt thereof. These compounds are inhibitors of topoisomerase I and II and can be used to treat tumours, including tumours which express MDR.
