生物活性:
DMUP is a potent CD47-SIRPα axis inhibitor. DMUP induces apoptosis and increases the macrophage phagocytosis in A549 cells. DMUP decreases the expression of CD47 and SIRPα protein. DMUP shows antitumor activity.

体内研究:
DMUP (10 mg/kg, i.v., every other day for 17 day) shows antitumor activity.DMUP (5, 10, 20, 40 mg/kg, i.v.,every two days for 18 days) shows no toxicity in mice.Animal Model:ICR mice
Dosage:5, 10, 20, 40 mg/kg
Administration:i.v., every two days, 18 days
Result:Showed low toxicity with LD50 of greater than 20 mg/kg.
Animal Model:A549 xenograft BALB/c nude mice
Dosage:10 mg/kg
Administration:i.v., every other day, 17 day
Result:Showed antitumor activity.

体外研究:
DMUP (72 h) shows antiproliferative activity with IC50s of 0.92, 3.58, 6.29, 1.54 μM for A549, A549/DDP, PANC-1, HepG2 cells, respectively.DMUP (5 μM, 24 h) arrests the cell cycle in S phase in A549 cells.DMUP (5 μM, 48 h) induces apoptosis in A549 cells.DMUP (5 μM, 24 h) decreases the expression of CD47 and SIRPα protein.DMUP (5 μM, 4 h) increases the macrophage phagocytosis in A549-GFP cells.
