Page/Page column 31, (2009/05/28)
The present invention relates to pharmaceutically stable crystalline forms of (5, 6-Dimethyl-9- oxo-9H-xanthene-4-yl) acetic acid (DMXAA) sodium salt,- processes for preparing those stable crystalline forms; pharmaceutical compositions comprising at least one of those crystalline forms in solid form or in dissolved form and a pharmaceutically acceptable carrier. Disclosed are methods of using those pharmaceutical compositions to treat tumours, optionally in combination with other active pharmaceutical agents.

Analogues of 9-oxo-9H-xanthene-4-acetic acid (XAA) bearing small, lipophilic 5-substituents are among the most dose-potent compounds yet reported with the capability of causing hemorrhagic necrosis of implanted colon 38 tumors in mice.To further extend structure-activity relationships among this class of compound, a series of XAA derivatives bearing two small lipophilic groups at various positions have been prepared and evaluated.The 5,6-disubstituted compounds in particular show consistently high levels of both dose potency and activity, suggesting this is the optimal configuration among substituted 9-oxo-9H-xanthene-4-acetic acids.The 5,6-dimethyl and 5-methyl-6-methoxy are the most effective analogues, showing in vivo colon 38 activity comparable to that of FAA at 10-15-fold lower doses and superior activity to FAA at the respective optimal doses, and the former has been selected for detailed evaluation.
