Antitumor agents. II. Bis(guanylhydrazones) of anthracene-9,10-dicarboxaldehydes
摘要:
9,10-Anthracenedicarboxaldehyde bis[(4,5-dihydro-1H-imidazol-2-yl)hydrazone] (bisantrene, VI-1) showed anticancer activity in mice vs. both leukemias and solid tumors. Increases in life span vs. the following neoplasms were: P-388 leukemia, 137%; B-16 melanoma, 122%; Lieberman plasma cell tumor, greater than 85%; colon tumor 26, 150%; Ridgway osteogenic sarcoma, 85%. There were significant numbers of long-term survivors. Both DNA and RNA synthesis were strongly inhibited. The drug was resistant to biodegradation and was bound strongly to tissues; in monkeys the half-life for disappearance from serum was 6 days. Related hydrazones were synthesized, and structure-activity relationships are discussed. Two routes to ring-substituted anthracene-9,10-dicarboxaldehyde intermediates were developed.

There is provided a process for the manufacture of substituted 9,10-anthracenedicarboxaldehydes and substituted 9,10-dihydro-9,10-anthracenedicarboxaldehydes useful as intermediates in the preparation of antibacterial agents.
This disclosure describes anthracene-9,10-bis-carbonyl-hydrazones and derivatives thereof useful as antibacterial agents, for inhibiting the growth of transplanted mouse tumors, and for inducing the regression and/or palliation of leukemia and related cancers.
