A series of 1-methyl-4,5-diphenylimidazoles 6 with various patterns of m-halogen substitution at the 5-phenyl ring were tested for cytotoxicity in cancer and nonmalignant cell lines and for their capacity to prevent tube formation in HUVEC cultures. Unlike the monofluoro and difluoro derivatives 6a and 6e, the monobromo and diiodo analogs 6c and 6h were strongly cytotoxic and inhibited the poly...
