A series of 5-aryl-2,3-dihydroimidazo<2,1-a>isoquinolines previously reported to be platelet activating factor (PAF) receptor antagonist were evaluated for potential antitumor activity.Several compounds, such as the 5-(4'-tert-butylphenyl) (65), 5-<4'-(trimethylsilyl)phenyl> (69), and 5-(4'-cyclohexylphenyl) (71) analogs showed very good cytotoxicity against several tumor cell lines. 5-<4'-(Piperidinomethyl)phenyl>-2,3-dihydroimidazo<2,1-a>isoquinoline (SDZ 62-434, 53) was more effective on a milligram per kilogram basis than the clinical cytostatic agent edelfosine (1) in increasing survivors and decreasing tumor volume in the oral mouse Meth A fibrosarcoma assay.It was selected for further development and is currently in phase I clinical trials in cancer patients.
