Abstract
Methods and compositions are provided for treating cancer, the methods including the step administering, either sequentially or simultaneously, (i) a compound of the xanthenone acetic acid group of compounds, and (ii) at least one compound selected from compounds which modulate TNF production and compounds which act on biochemical pathways leading to TNF synthesis. Compositions include a combination of (i) and (ii) above, together with acceptable pharmaceutical carriers and/or vehicles.
Claims12
A method of treating cancer, the method including the step of administering to a mammal in need of such treatment, either simultaneously or sequentially:
- (i) 5,6-dimethylxanthenone-4-acetic acid having the formula
- or a pharmaceutically acceptable salt or ester thereof;
- and
- (ii) a compound selected from the group consisting of deacylated LPS and a CD-14 receptor antibody, wherein said administering results in TNF-α induction in excess of that induced by either agent alone.
A pharmaceutical composition suitable for treating cancer, including
- (i) 5,6-dimethylxanthenone-4-acetic acid having the formula
- or a pharmaceutically acceptable salt or ester thereof, and
- (ii) a compound selected from the group consisting of deacylated LPS and a CD-14 receptor antibody, wherein the amounts of the compound of (i) and the compound of (ii) are selected to provide TNF-α induction in excess of that induced by either agent alone.
A method of preparing a medicament for treating cancer, comprising combining
- (i) 5,6-dimethylxanthenone-4-acetic acid having the formula
- or a pharmaceutically acceptable salt or ester thereof, with
- (ii) a compound selected from the group consisting of deacylated LPS and a CD-14 receptor antibody,
- wherein the amounts of the compound of (i) and the compound of (ii) are selected to provide TNF-α induction in excess of that induced by either agent alone.
A method of treating cancer, the method including the step of administering to a mammal in need of such treatment, either simultaneously or sequentially:
- (i) 5,6-dimethylxanthenone-4-acetic acid having the formula
- or a pharmaceutically acceptable salt or ester thereof;
- and
- (ii) a compound of deacylated LPS, wherein said administering results in TNF-α induction in excess of that induced by either a sent alone.
A pharmaceutical composition suitable for treating cancer, including
- (i) 5,6-dimethylxanthenone-4-acetic acid having the formula
- or a pharmaceutically acceptable salt or ester thereof, and
- (ii) a compound of deacylated LPS, wherein the amount of the compound of deacylated LPS is selected to provide TNF-α induction in excess of that induced by either agent alone.
A method of preparing a medicament for treating cancer, comprising combining
- (i) 5,6-dimethylxanthenone-4-acetic acid having the formula
- or a pharmaceutically acceptable salt or ester thereof, with
- (ii) a compound of deacylated LPS, wherein the amount of the compound of deacylated LPS is selected to provide TNF-α induction in excess of that induced by the compound of deacylated LPS alone.
