Definitions

• reaction mixture was concentrated, diluted with chloroform (50 mL), and the resultant solid was filtered through a sintered glass funnel and further washed with methanol (50 mL) to give bisindenoisoquinoline 14a (0.48 g, 80%) as a red solid: mp 240-242 0 C.
• Each compound was tested in the hollow fiber assay against a panel of twelve human tumor cell lines as described previously; see, Hollingshead, M.; Plowman, J.; Alley, M.; Mayo, J.; Sausville, E., The Hollow Fiber Assay. Contrib. Oncol. 1999, 54, 109-120; and Plowman, J.; Camalier, R.; Alley, M.; Sausville, E.; Schepartz, S. Contrib. Oncol. 1999, 54, 121-135, the disclosures of which are hereby incorporated by reference.
• the compounds were solubilized in 10% DMSO in saline/Tween-80 ® and administered intraperitoneally once daily for a total of four doses at each of two dose levels.
• the 161 bp fragment from pBluescript SK(-) phagemid DNA (Stratagene, La Jolla, CA) is cleaved with the restriction endonuclease Pvu II and Hind III (New England Biolabs, Beverly, MA) in supplied NE buffer 2 (10 ⁇ L reactions) for 1 h at 37 0 C, separated by electrophoresis in a 1% agarose gel made in IX TBE buffer.
• the 161 bp fragment is eluted from the gel slice (centrilutor by Aniicon) and concentrated in a centricon 50 centrifugal concentrator (Amicon, Beverly, MA).
• Approximately 200 ng of the fragment is 3 '-end-labeled at the Hind III site by fill-in reaction with [alpha- 32 P]-dCTP and 0.5 mM dATP, dGTP, and dTTP, in React 2 buffer (50 mM Tris-HCl, pH 8.0, 100 mM MgCl, 50 mM NaCl) with 0.5 units of DNA polymerase I (Klenow fragment). Labeling reactions are followed by phenol-chloroform extraction and ethanol precipitation. The resulting 161 bp 3'-endlabeled DNA fragment is resuspended in water.
• Electrophoresis is performed at 2500 V (60 W) for 2-5 h.
• the gels were dried and visualized using a Phosphoimager and ImageQuant software.
• Reactions are performed at 37 0 C for 30 min and terminated by the addition of 0.5% SDS, and then 1.1 ⁇ L of 1OX loading buffer (20% Ficol 400, 0.1 M Na 2 EDTA pH 8, 1.0% SDS, 0.25% Bromophenol Blue) is then added and reaction mixtures are loaded onto a 1% agarose gel made in K TBE buffer. After electrophoresis, DNA bands are stained in 10 ⁇ g/mL of ethidium bromide and visualized by transil lumination with UV light (300 ran).
• 1OX loading buffer 20% Ficol 400, 0.1 M Na 2 EDTA pH 8, 1.0% SDS, 0.25% Bromophenol Blue
• IP and SC scores listed are the sums of all the BP and SC scores for each compound.
• a net cell kill at one or more implant sites is indicated with a Y.
