Background:

LM985 is one of a series of compounds based on the flavone ring structure, with anti-tumor activities.

LM985 shows inhibitory effects against MAC 13 cells, but MAC 15A cells are less sensitive to LM985[1].

LM985 (200 mg/kg, s.c.) shows moderate activity against MAC 13, and after repeated injection 7 days, responses are considerably enhanced[2].
