  Synthesis and evaluation of unsymmetrical bis(arylcarboxamides) designed as topoisomerase-Targeted anticancer drugs

  摘要：

  Symmetrical dimers of lipophilic intercalating chromophores linked by cation-containing chains have recently been shown to have broad-spectrum in vivo anticancer activity. We report the preparation and evaluation of a series of both symmetric and unsymmetric dimers of a variety of intercalating chromophores of varied DNA binding strength, including naphthalimides, acridines, phenazines, oxanthrenes and 2-phenylquinolines. The unsymmetrical dimers were prepared by sequential coupling of the chromophores to linkers with selectively protected primary terminal amines to ensure high yields and unequivocal product. Protection of the internal (secondary) amines as BOC derivatives was used to ensure complete structural specificity, and was also an aid to the purification of these very polar compounds. The growth inhibitory abilities (as IC50 values) of the compounds in a range of cell lines showed that the nature of the linker chain was important, and independent of the nature of the chromophore, with compounds containing the dicationic linker [-(CH2)(2)NH(CH2)(2)NH(CH2)(2)-] being on average 30-fold more potent than the corresponding compounds containing the monocationic linker [-(CH2)(3)NMe(CH2)(3)-]. However, the chromophores also play a role in determining biological activity, with the cytotoxicities of symmetric and unsymmetric dicationic dimers correlating with the overall DNA binding abilities of the chromophores.

  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.
