Compositions containing the thioxanthenones and methods of treating tumors and cancer in mammals with the thioxanthenones are also disclosed.

Lyophilized thioxanthenone antitumor agents

Disclosed are reconstituted lyophilized formulations for the treatment of mammalian tumors comprising a thioxanthenone antitumor agent in combination with mannitol or sucrose as a stabilizer in a lactate buffer.

Thioxanthenone antitumor agents

1-[[(Dialkylamino)alkyl]amino]-4-substituted-thioxanthen-9-ones are disclosed as antitumor agents. Compositions containing the thioxanthenones and methods of treating tumors and cancer in mammals with the thioxanthenones are also disclosed.

Analogues of hycanthone and lucanthone as antitumor agents

Hycanthone analogues (5 and 6) containing 7-substituted hydroxyl groups were prepared and evaluated as antitumor agents. These compounds were significantly more active than the corresponding unsubtituted derivatives. The 7-hydroxylated-4-(hydroxymethyl)-9H-xanthen-9-ones, 11 and 12, were also active antitumor agents. However, the 7-hydroxy-9H-xanthen-9-one counterparts of the 7-hydroxylucanthones were totally devoid of antitumor activity. Results obtained thus far are consistent with the hypothesis that 4-hydroxymethyl substituents in the 9H-xanthen-9-one and 9H-thioxanthen-9-one series are required for antitumor activity.
