Analogs of hycanthone and lucanthone as antitumor agents
摘要:
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 unsubstituted 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.
Novel 2H-[1]benzothiopyrano[4,3,2-cd]indazoles are disclosed as antitumor agents. Compositions containing the benzothiopyranoindazoles and methods of treating tumors and cancer in mammals with benzothiopyranoindazoles are also disclosed.
