  DNA-Targeted 1,2,4-Benzotriazine 1,4-Dioxides:  Potent Analogues of the Hypoxia-Selective Cytotoxin Tirapazamine

  摘要：

  Tirapazamine (TPZ, 1,2,4-benzotriazin-3-amine 1,4-dioxide) is a bioreductive hypoxia-selective cytotoxin, currently in phase II/III clinical trials in combination with radiotherapy and with cisplatin-based chemotherapy. We have prepared a series of 1,2,4-benzotriazine 1,4-dioxide (BTO) analogues of TPZ where a DNA-targeting chromophore is attached at the 3-position via a flexible linker. DNA binding affinity was modified through variation of the chromophore or the pK(a) of the linker chain. The association constants (K-DNA) for calf thymus DNA ranged from 1 x 10(2) to 5.6 x 10(5) M-1 (ionic strength of 0.01 M). DNA binding affinity was dependent on the presence of a positive charge, either in the linker chain or in the chromophore, and (for a series of 4-acridine carboxamide chromophore analogues) correlated strongly with linker chain pKa. The efficacy of these BTOs in killing aerobic and hypoxic mouse SCCVII tumor cells in vitro was determined by clonogenic survival. Cytotoxicity was measured as the concentration required to reduce plating efficiency to 10% of controls (C-10), and the hypoxic cytotoxicity ratio (HCR) for each BTO was calculated as C-10(aerobic)/C-10(hypoxic). BTOs bearing a positive charge showed increased hypoxic cytotoxicity (1.5-56-fold) compared to TPZ and mostly modest HCRs (8-51), but some excellent (> 167 and 400) values. There was a strong correlation between K-DNA and hypoxic cytotoxicity but no correlation between K-DNA and HCR. Cytotoxicity in HT-29 human colon carcinoma cells, determined using IC50 assays, showed similar relationships with a correlation between KDNA and hypoxic cytotoxicity but no correlation between KDNA and HCR. In this cell line, a higher proportion of compounds (7 of 11) had HCRs greater than or equal to that of TPZ. The data confirm that DNA targeting is a useful concept for increasing potency while maintaining hypoxic selectivity and provide a direction for the further development of DNA-targeted analogues of TPZ.

  Potential antitumor agents. 57. 2-Phenylquinoline-8-carboxamides as minimal DNA-intercalating antitumor agents with in vivo solid tumor activity

  摘要：

  A series of phenyl-substituted derivatives of the "minimal" DNA-intercalating agent N-[2-(dimethylamino)-ethyl]-2-phenylquinoline-8-carboxamide (1) have been synthesized and evaluated for in vivo antitumor activity, in a continuing search for active compounds of this class with the lowest possible DNA association constants. Substitution on the 2'-position of the phenyl ring gave compounds of lower DNA binding ability that did not intercalate DNA, indicating that it is necessary for the phenyl ring to be essentially coplanar with the quinoline for intercalative binding. An extensive series of 4'-substituted derivatives was evaluated, but there was no overall relationship between biological activity and substituent lipophilic or electronic properties. However, several compounds showed good solid tumor activity, with the 4'-aza derivative 18 being clearly superior to the parent compound, effecting about 50% cures in both leukemia and solid tumor models.
