E. Kumazawa et al., SYNTHESIS AND ANTITUMOR-ACTIVITY OF NOVEL BENZOPHENONE DERIVATIVES, Chemical and Pharmaceutical Bulletin, 45(9), 1997, pp. 1470-1474
Novel benzophenone derivatives were synthesized and screened for cytot
oxic and antitumor activity. Friedel-Crafts condensation was employed
to construct the benzophenone skeleton. Among the compounds synthesize
d, morpholino and thiomorpholino benzophenones 3a-d exhibited potent c
ytotoxic activity against P388 murine leukemia and PC-6 human lung car
cinoma cells in vitro, and compounds 3a. 3c, and 3j, when administered
intraperitoneally, showed significant antitumor activity against the
malignant ascites caused by intraperitoneal inoculation of P388 cells
in mice.
