  Mammalian topoisomerase II inhibitory activity of 1-cyclopropyl-6,8-difluoro-1,4-dihydro-7-(2,6-dimethyl-4-pyridinyl)-4-oxo-3-quinolinecarboxylic acid and related derivatives

  摘要：

  1-Cyclopropyl-6,8-difluoro-1,4-dihydro-7-(2,6-dimethyl-4-pyridinyl)-4-oxo-3-quinolinecarboxylic acid (1), a previously reported potent inhibitor of bacterial DNA gyrase, was found to be interactive with mammalian topoisomerase II (topo II). In a DNA-cleavage assay using topo II isolated from HeLa cells, 1 exhibited an EC50 value of 7.6 muM (VP-16; EC50 = 0.81 muM). A series of analogues modified at the 1-, 2-, 3-, 5-, and 7-positions of 1 were subsequently made and assessed for topo II inhibition. Compound 1 was considerably more potent than derivatives where the 1-substituent was alkyl, aryl, or H, or when N-c-C3H5 was replaced with S. The descarboxyl (i.e., 3-H) analogue had potency comparable to that of 1; when both these compounds were substituted at the 2-position with methyl or phenyl, an interesting relationship between activity and the conformation of the carboxyl group emerged. Upon replacement of the 5-H of 1 with NH2 or F, sustained potency was seen. No enhancement of activity was evident upon replacing the 7-substituent of 1 with other pyridinyl groups, 4-methyl-1-piperazinyl, or pyrrolidinyl groups; however, the 7-(4-hydroxyphenyl) analogue (CP-115,953) was 6-fold more potent than 1. The topo II inhibitory properties of 1 translated to modest in vitro cytotoxicity and in vivo activity versus P388.
